    TODAY’S STUDY: U.S. TIDAL ENERGY POTENTIAL

    Assessment of Energy Production Potential from Tidal Streams in the United States
    June 29, 2011 (Georgia Tech Research Corporation)

    Executive Summary

    Tidal stream energy is one of the alternative energy sources that are renewable and clean. With the constantly increasing effort in promoting alternative energy, tidal streams have become one of the more promising energy sources due to their continuous, predictable and spatially-concentrated characteristics. However, the present lack of a full spatial-temporal assessment of tidal currents for the U.S. coastline down to the scale of individual devices is a barrier to the comprehensive development of tidal current energy technology. This project created a national database of tidal stream energy potential, as well as a GIS tool usable by industry in order to accelerate the market for tidal energy conversion technology.

    Tidal currents are numerically modeled with the Regional Ocean Modeling System and calibrated with the available measurements of tidal current speed and water level surface. The performance of the model in predicting the tidal currents and water levels is assessed with an independent validation. The geodatabase is published at a public domain via a spatial database engine and interactive tools to select, query and download the data are provided. Regions with the maximum of the average kinetic power density larger than 500 W/m2 (corresponding to a current speed of ~1 m/s), surface area larger than 0.5 km2 and depth larger than 5 m are defined as hotspots and list of hotspots along the USA coast is documented. The results of the regional assessment show that the state of Alaska (AK) contains the largest number of locations with considerably high kinetic power density, and is followed by, Maine (ME), Washington (WA), Oregon (OR), California (CA), New Hampshire (NH), Massachusetts (MA), New York (NY), New Jersey (NJ), North and South Carolina (NC, SC), Georgia (GA), and Florida (FL). The average tidal stream power density at some of these locations can be larger than 8 kW/m2 with surface areas on the order of few hundred kilometers squared, and depths larger than 100 meters. The Cook Inlet in AK is found to have a substantially large tidal stream power density sustained over a very large area.

    Background

    Tidal streams are high velocity sea currents created by periodic horizontal movement of the tides, often magnified by local topographical features such as headlands, inlets to inland lagoons, and straits. As tides ebb and flow, currents are often generated in coastal waters. In many places the shape of the seabed forces water to flow through narrow channels, or around headlands. Tidal stream energy extraction is derived from the kinetic energy of the moving flow; analogous to the way a wind turbine operates in air, and as such differs from tidal barrages, which create a head of water for energy extraction. A tidal stream energy converter extracts and converts the mechanical energy in the current into a transmittable energy form. A variety of conversion devices are currently being proposed or are under active development, from a water turbine similar to a scaled wind turbine, driving a generator via a gearbox, to an oscillating hydrofoil which drives a hydraulic motor.

    Tidal energy is one of the fastest growing emerging technologies in the renewable sector and is set to make a major contribution to carbon free energy generation.. The key advantage of tidal streams is the deterministic and precise energy production forecast governed by astronomy. In addition, the predictable slack water facilitates deployment and maintenance. In 2005, EPRI was first to study representative sites (Knik Arm, AK; Tacoma Narrows, WA; Golden Gate, CA; Muskeget Channel, MA; Western Passage, ME) without mapping the resources (EPRI, 2006g). Additional favorable sites exist in Puget Sound, New York, Connecticut, Cook Inlet, Southeast Alaska, and the Aleutian Islands among others. Besides large scale power production, tidal streams may serve as local and reliable energy sources for remote and dispersed coastal communities and islands. The extractable resource is not completely known; assuming 15% level of extraction, EPRI has documented 16 TWh/yr in Alaska, 0.6 TWh/yr in Puget Sound, and 0.4 TWh/yr in CA, MA, and ME (EPRI 2006b-f). The selection of location for a tidal stream energy converter farm is made upon assessment of a number of criteria:
    Tidal current velocity and flow rate: the direction, speed and volume of water passing through the site in space and time.

    click to enlarge

    Other site characteristics: bathymetry, water depth, geology of the seabed and environmental impacts will determine the deployment method needed and the cost of installation.

    Electrical grid connection and local cost of electricity: the seafloor cable distance from the proposed site to a grid access point and the cost of competing sources of electricity will also help determine the viability of an installation.

    Following the guidelines in the EPRI report for estimating tidal current energy resources (EPRI 2006a), preliminary investigations of the tidal currents can be conducted based on the tidal current predictions provided by NOAA tidal current stations (NOAA, 2008b). There are over 2700 of these stations which are sparsely distributed in inlets, rivers, channels and bays. The gauge stations are concentrated along navigation channels, harbors and rivers but widely absent elsewhere along the coast. As an example, the maximum powers at some of these locations around the Savannah River on the coast of Georgia are shown in Figure 1. The kinetic tidal power per unit area, power density, given in this figure were calculated using the equation where ρis the density of water and V is the magnitude of the depth averaged maximum velocity.

    click to enlarge

    These tidal currents and therefore the available power per unit area can have significant spatial variability (Figure 1); therefore, measurements (or predictions) of currents at one location are generally a poor indicator of conditions at another location, even nearby. It is clear that the majority of the data is available along the navigation channel in the Savannah River, with sparse data within the rest of the tidal area. EPRI (2006a) suggest a methodology using continuity and the Bernoulli equation for determining the flow in different sections of a channel. This is a reasonable approach for flow along a geometrically simple channel, but is not applicable for the flow in the complex network of rivers and creeks along much of the US coastline. Thus we have applied a state-ofthe-art numerical model for simulating the tidal flows along the coast of the entire United States…

    Total theoretical available power estimates

    The published maps and the database provide the distribution of the existing kinetic power density of tidal streams in the undisturbed flow conditions. These results do not include any technology assumptions or flow field effects as in the case of device arrays. In order to calculate a theoretical upper bound based on physics only, a simplified method that considers both the kinetic and potential power with the exclusion of any technology specific assumptions is applied. The details of the method is outlined in a recent paper (Garrett and Cummins, 2005). The power calculated with this method is used in estimating the tidal power potential for the entire country with a specific value for each state. The method uses undisturbed flow field from the model with simple analytical methods, accounts for the cumulative effect of dissipating energy and provides information on an estuary scale.
    Considering a constricted channel connecting two large bodies of water in which the tides at both ends are assumed to be unaffected by the currents through the channel, a general formula gives the maximum average power as between 20 and 24% of the peak tidal pressure head times the peak of the undisturbed mass flux through the channel. This maximum average power is independent of the location of the turbine fences along the channel…

    This upper bound on the available power ignores losses associated with turbine operation and assumes that turbines are deployed in uniform fences, with all the water passing through the turbines at each fence.

    This method is applied to the locations bounded between two land masses and has locally increased tidal current speed along the United States coast. A list of these locations grouped by state is given in Table 6. The list displays the coordinates and the name of each location (i.e. the midpoint) together with the width, mean/maximum of the constriction and the total theoretical available power. The totals are given for each state and for the entire country. Once again, Alaska with a total of 47GW constitutes the largest piece of the national total of 50 GW. Cook Inlet has the largest average maximum available power of 18 GW (Figure A22) closely followed by Chatham Strait with 12 GW (Figure A20). Alaska is stands out as an abundant resource of tidal stream…

    NEW PROOF OF CHINA’S SUN PRICE GAMING
    SolarWorld: Import Surge Shows Tariff Evasion By Chinese Solar Producers
    Jessica Lillian, 27 January 2012 (Solar Industry)

    "SolarWorld and its partners in the Coalition for American Solar Manufacturing (CASM) have unearthed new PV module import data that, according to the coalition, proves that Chinese solar producers flooded the market with product at the end of 2011. The CASM believes this information warrants the application of retroactive duties on Chinese imports.

    "SolarWorld filed its initial anti-dumping complaint and countervailing-duty petition last fall, claiming that low-priced crystalline silicon (c-Si) PV cells and modules from Chinese companies have violated international trade laws and harmed U.S.-based solar manufacturing…The International Trade Commission (ITC) made a preliminary determination last December that there is a ‘reasonable indication’ that Chinese manufacturers' practices are detrimental to the domestic solar industry…[The new CASM analysis] found that Chinese c-Si producers have more than doubled their imports into the U.S. since July 2011. This surge, the coalition says, constitutes ‘critical circumstances’ (as defined by the U.S. Department of Commerce) and justifies the implementation of tariffs on imports dating back to Nov. 15…[A decision on that is due] Feb. 15."

    CHINA’S VIEW ON TURBINE TOWER PRICE GAMING
    China Voices 'Deep Concern' Over U.S. Wind Tower Probe; Investigation by U.S. Commerce Department will examine whether towers from China and Vietnam were subsidized and sold at less than fair value.
    January 21, 2012 (AFP via Industry Week)

    "China expressed ‘deep concern’…after the U.S. launched a probe into Chinese wind towers that it suspects of being unduly subsidized and sold at a loss on the American market…[saying it would] hamper bilateral cooperation in the field of new energy…harm the interests of U.S. industries…[and] go against global efforts to tackle the challenges of climate change and energy security…

    TODAY’S STUDY: ENERGY OLD AND NEW, THE GOVERNMENT REPORT

    Annual Energy Outlook 2012 Early Release Overview
    January 23, 2012 (U.S. Energy Information Administration)

    AEO2012 Early Release Overview Executive Summary

    Projections in the Annual Energy Outlook 2012 (AEO2012) Reference case focus on the factors that shape U.S. energy markets in the long term, under the assumption that current laws and regulations remain generally unchanged throughout the projection period. The AEO2012 Reference case provides the basis for examination and discussion of energy market trends and serves as a starting point for analysis of potential changes in U.S. energy policies, rules, or regulations or potential technology breakthroughs. Some of the highlights in the AEO2012 Reference case include:

    Projected growth of energy use slows over the projection period, reflecting an extended economic recovery and increasing energy efficiency in end-use applications Projected transportation energy demand grows at an annual rate of 0.2 percent from 2010 through 2035 in the Reference case, and electricity demand grows by 0.8 percent per year. Energy consumption per capita declines by an average of 0.5 percent per year from 2010 to 2035. The energy intensity of the U.S. economy, measured as primary energy use in British thermal units (Btu) per dollar of gross domestic product (GDP) in 2005 dollars, declines by 42 percent from 2010 to 2035.

    Domestic crude oil production increases Domestic crude oil production has increased over the past few years, reversing a decline that began in 1986. U.S. crude oil production increased from 5.1 million barrels per day in 2007 to 5.5 million barrels per day in 2010. Over the next 10 years, continued development of tight oil, in combination with the ongoing development of offshore resources in the Gulf of Mexico, pushes domestic crude oil production in the Reference case to 6.7 million barrels per day in 2020, a level not seen since 1994. Even with a projected decline after 2020, U.S. crude oil production remains above 6.1 million barrels per day through 2035.

    With modest economic growth, increased efficiency, growing domestic production, and continued adoption of nonpetroleum liquids, net petroleum imports make up a smaller share of total liquids consumption U.S. dependence on imported petroleum liquids declines in the AEO2012 Reference case, primarily as a result of growth in domestic oil production by more than 1 million barrels per day by 2020; an increase in biofuels use of more than 1 million barrels per day crude oil equivalent by 2024; and modest growth in transportation sector demand through 2035. Net petroleum imports as a share of total U.S. liquid fuels consumed drop from 49 percent in 2010 to 36 percent in 2035 in AEO2012 (Figure 1). Proposed fuel economy standards covering vehicle model years 2017 through 2025 that are not included in the Reference case would further reduce projected liquids use and the need for liquids imports.

    Natural gas production increases throughout the projection period Much of the growth in natural gas production is a result of the application of recent technological advances and continued drilling in shale plays with high concentrations of natural gas liquids and crude oil, which have a higher value in energy equivalent terms than dry natural gas. Shale gas production increases from 5.0 trillion cubic feet in 2010 (23 percent of total U.S. dry gas production) to 13.6 trillion cubic feet in 2035 (49 percent of total U.S. dry gas production) (Figure 2).

    U.S. production of natural gas is expected to exceed consumption early in the next decade The United States is projected to become a net exporter of liquefied natural gas (LNG) in 2016, a net pipeline exporter in 2025, and an overall net exporter of natural gas in 2021. The outlook reflects increased use of LNG in markets outside of North America, strong domestic natural gas production, reduced pipeline imports and increased pipeline exports, and relatively low natural gas prices in the United States compared to other global markets.

    Use of renewable fuels and natural gas for electric power generation rises The natural gas share of electric power generation increases from 24 percent in 2010 to 27 percent in 2035, and the renewables share grows from 10 percent to 16 percent over the same period. In recent years, the U.S. electric power sector’s historical reliance on coal-fired power plants has begun to decline. Over the next 25 years, the projected coal share of overall electricity generation falls to 39 percent, well below the 49-percent share seen as recently as 2007 (Figure 3), because of slow growth in electricity demand, continued competition from natural gas and renewable plants, and the need to comply with new environmental regulations.

    Total U.S. energy-related carbon dioxide emissions remain below their 2005 level through 2035 Energy-related carbon dioxide (CO2) emissions grow by 3 percent from 2010 to 2035, to a total of 5,806 million metric tons in 2035. They are more than 7 percent below their 2005 level of 5,996 million metric tons in 2020 and are still below the 2005 level at the end of the projection period (Figure 4). Emissions per capita fall by an average of 1 percent per year from 2005 to 2035, as growth in demand for transportation fuels is moderated by higher energy prices and Federal corporate average fuel economy (CAFE) standards, and as electricity-related emissions are tempered by efficiency standards, State renewable portfolio standard (RPS) requirements, competitive natural gas prices that dampen coal use by electricity generators, and the need to comply with new environmental regulations. Proposed fuel economy standards covering model years 2017 through 2025 that are not included in the Reference case would further reduce projected energy use and emissions.

    Introduction

    In preparing the AEO2012 Reference case, the U.S. Energy Information Administration (EIA) evaluated a wide range of trends and issues that could have major implications for U.S. energy markets. This overview presents the AEO2012 Reference case and compares it with the AEO2011 Reference case released in April 2011 (see Table 1 on pages 12-13). Because of the uncertainties inherent in any energy market projection, the Reference case results should not be viewed in isolation. Readers are encouraged to review the alternative cases when the complete AEO2012 publication is released, in order to gain perspective on how variations in key assumptions can lead to different outlooks for energy markets.

    To provide a basis against which alternative cases and policies can be compared, the AEO2012 Reference case generally assumes that current laws and regulations affecting the energy sector remain unchanged throughout the projection (including the implication that laws which include sunset dates do, in fact, become ineffective at the time of those sunset dates). This assumption helps increase the comparability of the Reference case with other analyses, clarifies the relationship of the Reference case to other AEO2012 cases, and enables policy analysis with less uncertainty arising from speculative legal or regulatory assumptions. Currently, there are many pieces of legislation and regulation that appear to have some probability of being enacted in the not-too-distant future, and some existing laws include sunset provisions that may be extended. However, it is difficult to discern the exact forms that the final provisions of pending legislation or regulations will take, and sunset provisions may or may not be extended. Even in situations where existing legislation contains provisions to allow revision of implementing regulations, those provisions may not be exercised consistently. In certain situations, however, where it is clear that a law or regulation will take effect shortly after the AEO Reference case is completed, it may be considered in the projection.

    As in past editions of the AEO, the complete AEO2012 will include additional cases, many of which reflect the impacts of extending a variety of current energy programs beyond their current expiration dates and the permanent retention of a broad set of programs that currently are subject to sunset provisions. In addition to the alternative cases prepared for AEO2012, EIA has examined proposed policies at the request of Congress over the past few years. Reports describing the results of those analyses are available on EIA’s website.1

    Key updates made for the AEO2012 Reference case include the following:

    Industrial cogeneration was updated with historical rather than assumed capacity factors for new units and with updated investment decision procedures that reflect regional acceptance rates for new cogeneration facilities.

    A new heavy-duty vehicle model was adopted in the transportation module, with greater detail on size classes and end-use vehicle types to enable modeling of fuel economy regulations covering the heavy-duty vehicle fleet.

    The light-duty fleet model in the transportation module was updated to include a new algorithm for consumer purchase choice that compares fuel savings against incremental vehicle cost for advanced technologies, new technology cost and performance assumptions, and representation of fuel efficiency standards already in effect.

    Shale gas resource estimates for four plays (Haynesville, Fayetteville, Eagle Ford, and Woodford) were updated using the mean value of resource assessments recently released by the U.S. Geological Survey (USGS). The shale gas resource estimate for the Marcellus play was updated using new geologic data from the USGS and recent production data. EIA’s estimate of Marcellus resources is substantially below the estimate used for AEO2011 and falls within the 90-percent confidence range in the August 2011 USGS assessment, although it is higher than the USGS mean value.

    The tight oil resource estimate for the Bakken play was increased to include more of the Three Forks and Sanish zones.

    The handling of U.S. LNG exports of domestically sourced gas was updated, resulting in exports beginning in 2016.

    The electricity module was updated to incorporate the Cross-State Air Pollution Rule (CSAPR)2 as finalized by the EPA in July 2011. CSAPR requires reductions in emissions from power plants that contribute to ozone and fine particle pollution in 28 States.

    Assumptions regarding the potential for capacity uprates at existing nuclear plants and the timing for existing nuclear plant retirements were revised.

    Updates were made to reflect recent information pertaining to retirement dates for existing power plants and scheduled in-service dates for new power plants.

    California Assembly Bill 32 (AB 32), the Global Warming Solutions Act of 2006, was incorporated for electricity sector power plants serving California. As modeled, AB 32 imposes a limit on power sector CO2 emissions, beginning in 2012 and declining at a uniform annual rate through 2020.

    Economic growth

    Recovery from the 2008-2009 recession is expected to show the slowest growth of any recovery since 1960. Table 2 compares average annual growth rates over a five-year period following U.S. recessions that have occurred since 1960.

    For the most recent recession, the expected five-year average annual growth rate in real GDP from 2009 to 2014 is 1.3 percentage points below the corresponding average for the three past recessions, with consumption and non-farm employment recovering even more slowly. The slower growth in the early years of the projection has implications for the long term, with a lower economic growth rate leading to a slower recovery in employment and higher unemployment rates.

    Real GDP in 2035 is 4 percent lower in the AEO2012 Reference case than was projected in the AEO2011 Reference case. Real GDP grows by an average of 2.6 percent per year from 2010 to 2035 in the AEO2012 Reference case, 0.1 percent per year lower than in the AEO2011 Reference case. The Nation’s population, labor force, and productivity grow at annual rates of 0.9 percent, 0.7 percent, and 1.9 percent, respectively, from 2010 to 2035.

    Beyond 2012, the economic assumptions underlying the AEO2012 Reference case reflect trend projections that do not include short-term fluctuations. Economic growth projections for 2012 are consistent with those published in EIA’s October 2011 Short-Term Energy Outlook….

    Energy Prices…

    Natural gas

    With increased production, average annual wellhead prices for natural gas remain below $5 per thousand cubic feet (2010 dollars) through 2023 in the AEO2012 Reference case. The projected prices reflect continued industry success in tapping the Nation’s extensive shale gas resource. The resilience of drilling levels, despite low natural gas prices, is in part a result of high crude oil prices, which significantly improve the economics of natural gas plays that have high concentrations of crude oil, condensates, or natural gas liquids. After 2023, natural gas prices generally increase as the numbers of tight gas and shale gas wells drilled increase to meet growing domestic demand for natural gas and offset declines in natural gas production from other sources. Natural gas prices rise as production gradually shifts to resources that are less productive and more expensive. Natural gas wellhead prices (in 2010 dollars) reach $6.52 per thousand cubic feet in 2035, compared with $6.48 per thousand cubic feet (2010 dollars) in AEO2011.

    Coal

    The average minemouth price of coal increases by 1.4 percent per year in the AEO2012 Reference case, from $1.76 per million Btu in 2010 to $2.51 per million Btu in 2035 (2010 dollars). The upward trend of coal prices primarily reflects an expectation that cost savings from technological improvements in coal mining will be outweighed by increases in production costs associated with moving into reserves that are more costly to mine. The coal price outlook in the AEO2012 Reference case represents a change from the AEO2011 Reference case, where coal prices were essentially flat.

    click to enlarge

    Electricity

    Following the recent rapid decline of natural gas prices, real average delivered electricity prices in the AEO2012 Reference case fall from 9.8 cents per kilowatthour in 2010 to as low as 9.2 cents per kilowatthour in 2019, as natural gas prices remain relatively low. Electricity prices tend to reflect trends in fuel prices—particularly, natural gas prices, because in much of the country natural gas-fired plants often set wholesale power prices. It can take time, however, for fuel price changes to affect electricity prices because of the varying lengths of fuel- and power-supply contracts and the periods between electricity rate cases. In the AEO2012 Reference case, electricity prices are higher throughout the projection than they were in the AEO2011 Reference case. Although natural gas prices to electricity generators are similar to those in AEO2011, the cost of coal is higher. In addition, reliance on natural gas-fired generation in the power sector increases partially as a result of new environmental regulation covering emissions of sulfur dioxide (SO2) and nitrogen oxides (NOX) that make it a more economical option. Electricity prices in 2035 are 9.5 cents per kilowatthour (2010 dollars) in the AEO2012 Reference case, compared with 9.3 cents per kilowatthour in the AEO2011 Reference case….

    click to enlarge

    Electricity generation

    Total electricity consumption, including both purchases from electric power producers and on-site generation, grows from 3,879 billion kilowatthours in 2010 to 4,775 billion kilowatthours in 2035 in the AEO2012 Reference case, increasing at an average annual rate of 0.8 percent, about the same rate as in the AEO2011 Reference case.

    The combination of slow growth in electricity demand, competitively priced natural gas, programs encouraging renewable fuel use, and the implementation of new environmental rules dampens coal use in the future. The AEO2012 Reference case includes the impacts of the CSAPR, which was finalized in July 2011 and was not represented in the AEO2011 Reference case. CSAPR requires reductions in SO2 and NOX emissions in roughly one-half of the States, with an initial target in 2012 and further reductions in 2014. Even so, coal remains the dominant energy source for electricity generation, but its share of total generation declines from 45 percent in 2010 to 39 percent in 2035 (see Figure 3 on page 2). Market concerns about GHG emissions continue to slow the expansion of coal-fired capacity in the AEO2012 Reference case, even under current laws and policies. Low projected fuel prices for new natural gas-fired plants also affect the relative economics of coal-fired capacity, as does the continued rise in construction costs for new coal-fired power plants. As retirements outpace new additions, total coal-fired generating capacity falls from 318 gigawatts in 2010 to 301 gigawatts in 2035 in the AEO2012 Reference case.

    Electricity generation using natural gas is higher in the AEO2012 Reference case than was projected in the AEO2011 Reference case, particularly over the next 10 years, during which natural gas prices are expected to remain low. New natural gas-fired plants also are much cheaper to build than new renewable or nuclear plants. In 2015, natural gas-fired generation in AEO2012 is 13 percent higher than in AEO2011, and in 2035 it is still 6 percent higher. Electricity generation from nuclear power plants grows by 11 percent in the AEO2012 Reference case, from 807 billion kilowatthours in 2010 to 894 billion kilowatthours in 2035, accounting for about 18 percent of total generation in 2035 (compared with 20 percent in 2010).

    Nuclear generating capacity increases from 101 gigawatts in 2010 to a high of 115 gigawatts in 2025, after which a few retirements result in a decline to 112 gigawatts in 2035. AEO2012 incorporates new information about planned nuclear plant construction, as well as an updated estimate of the potential for capacity uprates at existing units. A total of 10 gigawatts of new nuclear capacity is projected through 2035, as well as an increase of 7 gigawatts achieved from uprates to existing nuclear units. About 6 gigawatts of existing nuclear capacity is retired, primarily in the last few years of the projection, as not all owners of existing nuclear capacity apply for and receive license renewals to operate their plants beyond 60 years. Increased generation from renewable energy in the electric power sector, excluding hydropower, accounts for 33 percent of the overall growth in electricity generation from 2010 to 2035.

    Generation from renewable resources grows in response to Federal tax credits, State-level policies, and Federal requirements to use more biomass-based transportation fuels, some of which can produce electricity as a byproduct of the production process. Near-term market growth in some sectors, such as solar energy, is projected to result in significantly reduced costs in the AEO2012 Reference case, increasing the projected growth for those resources as compared with the AEO2011 projections. More retirements of coal-fired capacity are expected in the AEO2012 Reference case than were projected in AEO2011 because of slower growth in electricity demand, continued competition from natural gas and renewable plants, and the need to comply with new environmental regulations. Growth in renewable generation is supported by many State requirements, as well as new regulations on CO2 emissions in California. The share of U.S. electricity generation coming from renewable fuels (including conventional hydropower) grows from 10 percent in 2010 to 16 percent in 2035. In the AEO2012 Reference case, Federal subsidies for renewable generation are assumed to expire as enacted. Extensions of such subsidies could have a large impact on renewable generation.

    Energy-related CO2 emissions

    Although total U.S. energy-related CO2 emissions increased by almost 4 percent in 2010, they do not return to their 2005 level (5,996 million metric tons) by the end of the AEO2012 projection period (see Figure 4 on page 2). Emissions per capita fall by an average of 1 percent per year from 2005 to 2035, as growth in demand for transportation fuels is moderated by higher energy prices and Federal CAFE standards. In addition, electricity-related emissions are tempered by efficiency standards, State RPS requirements, and implementation of the CSAPR, which helps shift the fuel mix away from coal toward lower carbon fuels.

    click to enlarge

    Energy-related CO2 emissions reflect the mix of fossil fuels consumed. Given the high carbon content of coal and its use to generate 45 percent of the U.S. electricity supply in 2010, prospects for CO2 emissions depend, in part, on growth in electricity demand as well as the portion of that demand satisfied by coal-fired generation. After declining from 2007 to 2009, electricity sales grew in 2010 by 4.3 percent. Electricity sales continue to grow through 2035 in the AEO2012 Reference case, but the growth is tempered by a variety of regulatory and socioeconomic factors, including appliance and building efficiency standards and a continued transition to a more service-oriented economy. The combination of slow demand growth, competitive natural gas prices, and CSAPR included in the AEO2012 Reference case lowers the consumption of coal within the first 5 years of the projection period; as a result, emissions from coal combustion in the power sector in 2015 are 149 million metric tons below the AEO2011 Reference case projection. With modest growth in electricity demand and increased use of renewables for electricity generation, electricity-related CO2 emissions grow by a total of 4.9 percent (0.2 percent per year) from 2010 to 2035. Growth in CO2 emissions from transportation activity also slows in comparison with the recent pre-recession experience, as Federal CAFE standards increase the efficiency of the vehicle fleet, employment recovers slowly, and higher fuel prices moderate growth in travel. The AEO2012 Reference case projections do not include proposed increases in fuel economy standards for model years 2017 through 2025, which are expected to further reduce fuel use and emissions.

    Taken together, these factors tend to slow the growth in primary energy consumption and CO2 emissions. As a result, energy-related CO2 emissions in 2035 are only 3 percent higher than in 2010 (as compared with the 10-percent increase in total energy use), and the carbon intensity of U.S. energy consumption falls from 57.4 to 53.8 kilograms per million Btu (6.3 percent). Over the same period, U.S. economic activity becomes less carbon-intensive, as energy-related CO2 emissions per dollar of GDP decline by 45 percent.

    "A new and detailed bottom-up analysis of the polysilicon industry by GTM Research further supports growing consensus that polysilicon prices will continue to set record lows in 2012 as they did in 2011 as overcapacity continues. Lower silicon prices in 2012 will likely lead to even lower c-Si module prices and force higher-cost poly producers to exit the market.

    WHAT ENERGY EFFICIENCY MEANS TO THE WORLD

    Exploiting the full potential of energy efficiency; New IEA report offers detailed guidance for governments on how to partner with private sector to finance energy efficiency measures
    19 January 2012 (International Energy Agency)

    "Improvements in energy efficiency can achieve a whole array of economic, societal and environmental benefits, often at low cost. In many cases it seems unexplainable that consumers, business and government authorities do not exploit the full potential of energy efficiency, yet there are a range of market and human behavioural failures that stop us from doing so.

    "Improving energy efficiency often requires an initial upfront cost, for example, for a more advanced or new piece of technology, a change in process, or the refurbishment of a building, that is paid back later through reduced energy bills. Even though the rate of return in investment in energy efficiency can be high, lack of finance can still be a key barrier to investment in energy efficiency."

    TODAY’S STUDY: THE CELTIC TIGER BUILDS A SMART GRID

    Smart Grid Roadmap to 2050
    January 2012 (Sustainable Energy Authority of Ireland)

    Introduction

    Ireland faces the same long term energy challenges as the rest of the world: a need to move towards competitively priced, environmentally sustainable, low carbon energy sources; and an insecure supply of conventional fossil fuels on which we are now dependent.

    click to enlarge

    A smart grid can help us address these challenges by maximising our use of indigenous low carbon renewable energy resources. A systems-based approach that optimises energy supply with demand for energy services and maximises our use of indigenous renewable electricity is central to ensuring Ireland meets its long term target of a secure and low carbon future.

    While Ireland has plentiful wind and ocean energy resources that can produce low carbon electricity, they are variable in nature. Being an island nation with small amounts of interconnection to other electricity markets creates significant technical challenges to utilising these variable resources. However, if we can find ways of moving some of our electricity demand to periods when renewable supply is available, we will increase our ability to use our indigenous low carbon resource. This requires significantly increased information flow between producers, users, and system and infrastructure operators. The combination of systems, infrastructure, policies and technologies that enables a shift away from the traditional model of electricity supply following demand towards a model where demand follows the availability of low carbon, but variable, renewable supply can be collectively called the “smart grid”.

    click to enlarge

    Building on work done by the International Energy Agency, this roadmap explores how the smart gird can contribute towards increasing the amount of renewable energy on the electricity system, improving our energy supply security and meeting Ireland’s long term emissions reduction targets. It was developed in conjunction with a roadmap for wind energy and electric vehicle deployment in Ireland, and consistent assumptions are used across the three. The roadmap has been developed with input and advice from a wide range of stakeholders and experts in the smart grid arena. It identifies a number of key steps required to achieve a smart grid scenario resulting in 13.4 million tonnes of CO2 emission reduction by 2050. These include developing market structures and policies that encourage: increasing electrification of potentially flexible loads (residential and commercial space heating and cooling and water heating), demand side management, and deployment of technologies that provide greater system flexibility such as energy storage, distributed generation and load aggregators. This in turn will require equipment, control systems and communications networks to operate on harmonised protocols.

    A number of key actions required are already in train. Communication systems between generation and networks and transmission system operators are already advanced and continuing to improve. The national smart meter rollout, scheduled to be completed by 2018, will enable real time monitoring of the system at the low voltage network level which will allow the participation in the market of distributed generation and virtual power plants. More importantly, it will allow electricity suppliers to offer pricing packages that provide customers with options and incentives to manage their electricity usage and costs. This increased level of customer participation is essential as it is this which creates the opportunity to shift electricity consumption to periods where variable renewable energy is available.

    Ireland is well positioned to lead in the deployment of the smart grid. The key energy sector actors are already engaged and looking to benefit from application of a smart grid. Many key ICT and energy equipment sector companies are looking to Ireland as a possible market in which to test smart grid products and concepts. Finally, Ireland has world leading research capacity in integrating large amounts of variable renewables into power systems. Now is the time to capitalise on this position, develop the expertise and technologies that will enable us to become world leaders, and develop an enterprise and innovation sector around smart infrastructure.

    Finally, I want to thank the organisations, listed on the back cover, that participated in the steering group that supported the development of this roadmap.

    Key Findings

    This roadmap explores how a smart grid can be operational in Ireland by 2050 and examines the contribution this will make to the decarbonisation of the electricity supply.

    ●● Decarbonisation of electricity in the Irish system will result in annual savings of over 13 million tonnes of CO2 by 2050. Eight million tonnes of this will be derived directly from the implementation of smart grid. A further five million tonnes will come from the displacement of fossil fuels due to the electrification of transport and thermal loads, facilitated by the smart grid

    click to enlarge

    ●● Greater integration of indigenous renewable energy sources will see a net reduction in energy imports in excess of 4.3 Mtoe, [equating to savings of €3.2-7.2bn in direct fuel offset by 2050]

    ●● Increasing the electrification of thermal loads in the residential and services sector will see an annual demand in this sector in excess of 28,000 GWh by 2050

    ●● Electrification of transport, predominately in the domestic sector, will be expected to provide an annual demand close to 8,000 GWh by 2050

    click to enlarge

    ●● Overall annual electrical final energy demand will be in excess of 48,000 GWh by 2050 with a corresponding peak demand of 9 GW. On-shore wind generation will be able to supply up to 33,000 GWh of the total demand

    ●● By 2025 Ireland will have 1.4 GW of interconnection. Our analysis indicates that a further 1.6 GW of interconnection will be required by 2040

    ●● More than 10,000 Irish jobs will be created by implementation of smart grid infrastructure and its associated technologies

    Matching demand to supply

    By enabling demand response, load balancing, load shifting and reduction, the integration of electrical storage and the management of the import and export of electricity, the smart grid will enable large amounts of distributed generation and renewable wind electricity onto the system, thus improving security of supply. However, the asynchronous, variable nature of wind means that demand must be matched to meet supply. This will require strategies and mechanisms in place to shift, store or export excess generation in order to maximise the amount of total final energy that can be delivered from wind and other distributed generation sources.

    Smart Grid – the ambitious scenario

    Predictions indicate that Ireland’s total wind resource could generate up to 140,000 GWh by 2050 (see SEAI Wind Roadmap). More than a third of this could be consumed domestically by aggressively increasing demand in the transport sector and built environment. By electrifying up to 50% of the transport fleet and over 90% of building thermal loads, the annual electrical demand could be increased to 80,000 GWh. This would enable over 50,000 GWh of variable wind generation to be accommodated on the system. When added to increases in generation from ocean energy and biomass, nearly 65,000 GWh of this demand could be met by renewable resources. This would represent an annual reduction in CO2 emissions of 25 million tonnes with a corresponding reduction in fuel exports of 8.5 Mtoe. In a medium price scenario where oil is at $179 / barrel this equates to savings of over €7.5 billion per year.

    OBAMA SOTU BACKS NEW ENERGY
    State Of The Union Address Calls For Comprehensive Energy Approach
    Jessica Lillian, 25 January 2012 (Solar Industry)

    "Although President Barack Obama's Jan. 24 State of the Union address contained only a singular mention of solar energy, he reiterated his commitment to expanding clean energy project development in the U.S. and ending subsidies to fossil-fuel companies…

    "In a follow-up proposal posted online by the White House, Obama specifically called for a temporary extension of the Advanced Energy Manufacturing Tax Credit as part of a broader manufacturing tax-reform proposal. This $5 billion investment would drive nearly $20 billion in domestic clean energy manufacturing, the White House said. The tax credit was previously oversubscribed more than three times over."

    "During his address, acknowledging that Congress' partisan divide may prevent broad action on climate change, the president nonetheless urged Congress to set a national clean energy standard. However, he made no mention of the 80% by 2035 clean energy standard that he introduced in last year's State of the Union.

    "Much of Obama's energy-independence discussion centered on increased exploration of domestic oil and natural-gas resources, as he advocated for the ‘all of the above’ energy approach that has been frequently espoused by more-conservative policymakers. He noted that the same public-private partnerships used in the natural-gas sector may also be applicable to renewable energy investment…Global competitiveness in clean energy - and beyond - also requires an increased emphasis on ensuring fair trade policies, Obama said. To that end, a newly created Trade Enforcement unit will investigate cases of unfair trading practices…"

    [Mahesh Shah, CEO, Figtree:] “PACE bond financing provides property owners fixed-rate, property value based and no credit check financing…The taxable municipal bond was sold to the capital markets without any state or federal funding assistance – a 100% private program…”

    "Under Assembly Bill 811, California property owners in special assessment districts may enter into voluntary contractual assessments against their properties to finance energy and water efficiency products. The financed amount incurred by the property owner is repaid over time through annual property tax assessments with the charge appearing as a line item on the property tax bill…[The bill can both] lower greenhouse gas levels and reduce energy and water consumption…[and be] a stimulus program that spurs local economic growth and creates new jobs…"


    COMMERCE INVESTIGATES ASIAN WIND
    U.S. Commerce Department Investigating Unfair Trade Of Wind Towers From China, Vietnam
    20 January 2012 (North American Windpower)

    "The U.S. Department of Commerce (DOC) has launched a formal investigation into the unfairly traded imports of wind towers from China and Vietnam…[following a complaint] filed by the Wind Tower Trade Coalition (WTTC) seeking investigation into the matter.

    "The DOC [found] an anti-dumping margin for China of 213.54% and an antidumping margin for Vietnam of between 140.54% and 143.29%....[T]he department has decided to investigate subsidy programs used by all levels of the Chinese government to support its wind turbine industry."
