US Wind Power Statistics

Total Available Renewable Resource

Several commenters questioned Friday's post on the grounds that the total amount of solar and wind power potentially available is insufficient to power modern civilization

This is incorrect.

Total available wind power available on land and near shore has been estimated at 72TW.   This is close to five times current total primary energy consumption, and still more than twice as large as energy consumption in 2040 (extrapolating at the 2.7% growth rate of the last decade).

Of course, not all technically and economically feasible wind sites are politically feasible.  Thus it's important that total incoming solar radiation is also very large.  Top of the atmosphere incoming solar radiation is 174000TW.  If we just look at the world's desert areas, they represent about a third of the global land area, itself about 30% of the total surface.  Allowing 30% losses in the atmosphere over deserts, and throwing out something for Antarctica (a desert, but not a very useful one for solar power), we end up with something in the ballpark of 7000TW of available solar energy from deserts alone.  This is hundreds of times larger than current civilizational energy consumption.

Therefore, constraints on our ability to utilize renewables are political and economic, not ultimate physical ones; there is plenty of renewable energy out there.

Nantucket Sound Wind Project Approved

Interior Dept press release:

BOSTON, Mass – Secretary of the Interior Ken Salazar today approved the Cape Wind renewable energy project on federal submerged lands in Nantucket Sound, but will require the developer of the $1 billion wind farm to agree to additional binding measures to minimize the potential adverse impacts of construction and operation of the facility.

“After careful consideration of all the concerns expressed during the lengthy review and consultation process and thorough analyses of the many factors involved, I find that the public benefits weigh in favor of approving the Cape Wind project at the Horseshoe Shoal location,” Salazar said in an announcement at the State House in Boston. “With this decision we are beginning a new direction in our Nation’s energy future, ushering in America’s first offshore wind energy facility and opening a new chapter in the history of this region.”

The Cape Wind project would be the first wind farm on the U.S. Outer Continental Shelf, generating enough power to meet 75 percent of the electricity demand for Cape Cod, Martha's Vineyard and Nantucket Island combined. The project would create several hundred construction jobs and be one of the largest greenhouse gas reduction initiatives in the nation, cutting carbon dioxide emissions from conventional power plants by 700,000 tons annually. That is equivalent to removing 175,000 cars from the road for a year.

A number of similar projects have been proposed for other northeast coastal states, positioning the region to tap 1 million megawatts of offshore Atlantic wind energy potential, which could create thousands of manufacturing, construction and operations jobs and displace older, inefficient fossil-fueled generating plants, helping significantly to combat climate change.
