Glenn Schleede has updated his 2006 white paper which discuses whether wind energy will reduce US reliance on oil. One of the claims often made by wind energy advocates is that greater use of wind energy for electricity generation will reduce US dependence on oil, including oil imports. In fact, adding more wind turbines will have no significant impact on US oil consumption. This update, based on the latest data from the US Energy Information Agency explains why the reduced oil use claim is false.

The November passage of Initiative 937 adds Washington to the states with renewable portfolio standards. Wind-powered generation is a resource of choice in meeting renewable standards, and it has been highly touted for its environmental benefits. Considered in isolation, the environmental benefits of a wind resource are undoubtedly warranted. However, it is misleading to consider wind on an isolated basis—that is, outside of the context of the full power-supply portfolio that is necessary to serve load. In the context of an integrated portfolio, much of the environmental benefit disappears and may even be non-existent as compared with other resource portfolio choices. In particular, a full assessment of the impact of wind resources on the environment necessitates a look at the energy consequences of adding wind-generation to an integrated portfolio in the context of meeting load. Accounting for energy, it is likely that there is no significant environmental difference between a resource portfolio adding wind generation and one adding high-efficiency combined-cycle gas turbines. It is also likely that the wind-based portfolio results in little reduction, if any, in the need for fossil fuels and therefore little reduction in the exposure to their price swings and environmental consequences. That is, the emissions and fossil-fuel impacts of a wind-based portfolio appear little better than a non-wind-based portfolio.

Editor's Note: This paper makes a critically important point re. wind's purported environmental benefits, i.e. "...it is misleading to consider wind on an isolated basis—that is, outside of the context of the full power-supply portfolio that is necessary to serve load. In the context of an integrated portfolio, much of the environmental benefit disappears and may even be non-existent as compared with other resource portfolio choices." In short, wind's environmental benefits (if any) will be grid-specific depending on the emissions generated (if any) of the reliable generating source(s) required to back it up.

DOE released its first Annual Report on U.S. Wind Power Installation, Cost, and Performance Trends: 2006 on May 31st, providing an overview of developments and trends in the U.S. wind power market. The report analyzes trends in the marketplace, including wind power prices compared to wholesale electricity prices, project costs, turbine sizes, and developer consolidation. It also describes the increasing performance of wind projects, current ownership and financing structures, and trends among major wind power purchasers.
The report notes that U.S. wind power capacity increased by 27 percent in 2006 and that the United States had the fastest-growing wind power capacity in the world in 2005 and 2006. For the second straight year, the United States led the world by installing 2,454 megawatts of wind power capacity in 2006—16 percent of the capacity installed worldwide that year—followed by Germany, India, Spain, and China. Leading the way in annual growth capacity in the United States are Texas, Washington, and California.

For those who think developers' feverish promotion of wind energy is about saving the planet, think again. The old adage follow the money explains their zeal much more than do its purported benefits. Worse, the enormous investment returns available to wind developers for an unreliable energy source that offers negligible emissions benefits stem largely from federal and state subsidies paid for by taxpayers and rate payers. Go figure.

The latest annual energy forecast issued by the US Energy Information Administration (EIA) indicates that, by the year 2030, wind energy would supply less than 1% of US electric generation and about 4/10 of 1% of total US energy consumption.
This forecast, which likely overstates the potential contribution of wind energy, helps show that officials of the wind industry and US Department of Energy are misleading the public, media and government officials with their claims that wind might supply 20% of US electricity.
