DOE Report Finds Big Future for Wind, Cites Challenges
A new U.S. Department of Energy report finds that wind power could supply up to one-fifth of the nation's electricity by 2030 but not without overcoming challenges such as improving the nation's transmission system.
The news media found lots to note in the report. The Washington Post wrote of the report's findings that wind could displace 50 percent of natural gas consumption and 18 percent of coal consumption in the United States (see story here). The San Francisco Chronicle, meanwhile, cited California's pioneering place in wind power history and cited major new wind farms under development in the state (see story here).
Separately, in a speech to a gathering of scientists, business executives and political leaders co-sponsored by a Republican group, Gov. Arnold Schwarzenegger touted California's emphasis on alternative energy as a way of fighting global warming. In his address, the governor noted that California patents account for 37 percent of all U.S. patents in wind technology (see press statement here).
The report, "20 Percent Wind Energy by 2030," found that significant hurdles remained to reaching the goal, including such potentially controversial efforts as expanding the transmission grid, as well as improving turbine technology and expanding markets for the power (see press statement here; full report here). In fact, it noted that a new "transmission superhighway system" could be needed to serve the wind farms and it cited one model showing it would be cost-effective to build more than 12,000 miles of additional transmission, at a cost of about $20 billion.
Transmission debates have already begun heating up in some parts of the country and have been identified by experts as a major issue in developing renewable resources (see Climate Law Update stories here and here).
In order to reach the 20 percent figure, the energy department report estimates that wind power capacity would have to reach more than 300,000 megawatts, compared to today's capacity of less than 12,000 megawatts.

Global warming is bad, and developing renewable energy to help solve the problem is good, right? While that might be a popular view, the reality is a bit more complicated, as experts in the field have begun noting with some frequency lately.
California utility regulators have voted to commit more than a half-billion dollars – paid for by the ratepayers of the state’s privately owned utilities -- to a research and development effort devoted to finding new technologies to reduce greenhouse gas emissions and getting them to market.
