||||||
Tax Credits and Renewable Generation (released in AEO2009)
Released: March 31, 2009 Tax incentives have been an important factor in the growth of renewable generation over the past decade, and they could continue to be important in the future. The Energy Tax Act of 1978 (Public Law 95-618) established ITCs for wind, and EPACT92 established the Renewable Electricity Production Credit (more commonly called the PTC) as an incentive to promote certain kinds of renewable generation beyond wind on the basis of production levels. Specifically, the PTC provided an inflation-adjusted tax credit of 1.5 cents per kilowatthour for generation sold from qualifying facilities during the first 10 years of operation. The credit was available initially to wind plants and facilities that used closed-loop biomass fuels [75] and were placed in service after passage of the Act and before June 1999. |
||||||
Greenhouse Gas Concerns and Power Sector Planning (released in AEO2009)
Released: March 13, 2009 Concerns about potential climate change driven by rising atmospheric concentrations of GHGs have grown over the past two decades, both domestically and abroad. In the United States, potential policies to limit or reduce GHG emissions are in various stages of development at the State, regional, and Federal levels. In addition to ongoing uncertainty with respect to future growth in energy demand and the costs of fuel, labor, and new plant construction, U.S. electric power companies must consider the effects of potential policy changes to limit or reduce GHG emissions that would significantly alter their planning and operating decisions. The possibility of such changes may already be affecting planning decisions for new generating capacity. |
||||||
Distributed Generation in Buildings (released in AEO2005)
Released: September 24, 2008 Currently, distributed generation provides a very small share of residential and commercial electricity requirements in the United States. The AEO2005 reference case projects a significant increase in electricity generation in the buildings sector, but distributed generation is expected to remain a small contributor to the sectors energy needs. Although the advent of higher energy prices or more rapid improvement in technology could increase the use of distributed generation relative to the reference case projection, the vast majority of electricity used in buildings is projected to continue to be purchased from the grid. |
||||||
Limited Electricity Generation Supply and Limited Natural Gas Supply Cases (released in AEO2008)
Released: June 26, 2008 Development of U.S. energy resources and the permitting and construction of large energy facilities have become increasingly difficult over the past 20 years, and they could become even more difficult in the future. Growing public concern about global warming and CO2 emissions also casts doubt on future consumption of fossil fuelsparticularly coal, which releases the largest amount of CO2 per unit of energy produced. Even without regulations to limit greenhouse gas emissions in the United States, the investment community may already be limiting the future use of some energy options. In addition, there is considerable uncertainty about the future availability of, and access to, both domestic and foreign natural gas resources. |
||||||
Loan Guarantees and the Economics of Electricity Generating Technologies (released in AEO2007)
Released: March 11, 2007 The loan guarantee program authorized in Title XVII of EPACT2005 is not included in AEO2007, because the Federal Credit Reform Act of 1990 requires congressional authorization of loan guarantees in an appropriations act before a Federal agency can make a binding loan guarantee agreement. As of October 2006, Congress had not provided the legislation necessary for DOE to implement the loan guarantee program (see Legislation and Regulations). In August 2006, however, DOE invited firms to submit pre applications for the first $2 billion in potential loan guarantees. |
||||||
Impacts of Temperature Variation on Energy Demand in Buildings (released in AEO2005)
Released: April 1, 2005 In the residential and commercial sectors, heating and cooling account for more than 40 percent of end-use energy demand. As a result, energy consumption in those sectors can vary significantly from year to year, depending on yearly average temperatures. |
||||||
Production Tax Credit for Renewable Electricity Generation (released in AEO2005)
Released: April 1, 2005 In the late 1970s and early 1980s, environmental and energy security concerns were addressed at the Federal level by several key pieces of energy legislation. Among them, the Public Utility Regulatory Policies Act of 1978 (PURPA), P.L. 95-617, required regulated power utilities to purchase alternative electricity generation from qualified generating facilities, including small-scale renewable generators; and the Investment Tax Credit (ITC), P.L. 95-618, part of the Energy Tax Act of 1978, provided a 10-percent Federal tax credit on new investment in capital-intensive wind and solar generation technologies. |

Analysis of a 10-percent Renewable Portfolio Standard
Released: May 1, 2003 On May 8, 2003, Senator Jeff Bingaman, the Ranking Minority Member of the Senate Committee on Energy and Natural Resources, requested an analysis of a nationwide Renewable Portfolio Standard (RPS) program proposed to be amended to energy legislation currently pending before the U.S. Senate1. With his request Sen. Bingaman provided specific information on the program to be analyzed. This analysis was prepared in response to his request and projects the impact of the proposed program on energy supply, demand, prices, and emissions. The analysis is based on the Annual Energy Outlook 2003 (AEO2003) projections of energy supply, demand, and prices through 2025, as updated in May 2003. |

Power Plant Emission Reductions Using a Generation Performance Standard
Released: May 1, 2001 In an earlier analysis completed in response to a request received from Representative David McIntosh, Chairman of the Subcommittee on National Economic Growth, Natural Resources, and Regulatory Affairs, the Energy Information Administration analyzed the impacts of power sector caps on nitrogen oxides, sulfur dioxide, and carbon dioxide emissions, assuming a policy instrument patterned after the sulfur dioxide allowance program created in the Clean Air Act Amendments of 1990.
