Washington, D.C. — American wind energy generation has outpaced the growth in new wind power capacity thanks to innovative technological advancements. Over the past five years, U.S. wind energy capacity grew from 25,000 megawatts (MW) to over 61,000 MW, a 140 percent growth rate, yet electricity generated from these wind turbines grew at a rate of 200 percent, exceeding capacity growth and making wind energy cheaper than ever.
The increasing performance and production of wind turbines is the result of technological innovation and operational improvements, which has effectively driven down the costs and allowed development to occur in lower wind speed regions. Advancements undertaken by manufacturers include designing taller towers and turbines with longer and lighter blades allowing rotor diameters to exceed 100 meters, larger than the wingspan of the largest commercial jets. The power of the wind is directly proportional to the swept area of the blades, so an increase in rotor diameter has spurred development in low and medium wind speed areas and has added to the efficiency of existing sites.

America’s clean energy economy created nearly 80,000 green jobs in 2013, benefitting virtually every state across the country even as looming market and policy uncertainty threaten to shrink green growth.
Solar, energy efficiency, and public transportation created the highest number of green jobs in America last year, according to the second annual Clean Energy Works For Us report from Environmental Entrepreneurs (E2).

First, the good news — break out the champagne! The overwhelming majority of new U.S. electrical capacity is coming from wind and solar, according to the Federal Energy Regulatory Commission. FERC just released its monthly analysis for February, and the Sun Day campaign, a research and advocacy organization promoting sustainable energy, summarizes the findings:

Iowa has been a prime example for the progress of wind energy in the past few years. As this article shows, Iowa’s wind energy benefits extend from being an electricity generator and economic driver, it drastically cuts pollution and benefits the environment. Read on.

Iowa’s hugely successful wind industry isn’t just an economic driver, it’s having a major impact on cutting pollution and saving water. Wind energy generation in Iowa avoids more than 8.4 million metric tons of climate-altering carbon pollution — the equivalent of taking 1.7 million cars off the road, according to a new report released by Environment Iowa.
Additionally, the report found that wind energy saves Iowans nearly 3.8 billion gallons of water per year, enough to meet the needs of over 158,000 people. The U.S. National Drought Monitor shows a significant portion of the state is in moderate to severe drought conditions and has been for several months.

Occasionally a misinformed reader asserts wind turbines produce insignificant electrical output. That’s simply untrue.
MGE reports the energy produced by its wind turbines annually. According to reports, its Rosiere Wind Farm in Kewaunee County produced 19,513,000 kilowatt hours in 2011 and 20,279,000 in 2012, the former at an operating cost of 2.11 cents per kilowatt hour.

The rapidly increasing cost of utilities in Australia—energy in particular—has had much media coverage lately. We found an interesting, industry-backed article on the AWEA blog by Michael Goggin about wind helping lower energy prices during peak usage periods. In addition to … Continue reading Wind energy lowers market price of energy during seasonal peaks

The decision by Warren Buffett’s utility company to order about $1 billion of wind turbines for projects in Iowa shows how a drop in equipment costs is making renewable energy more competitive with power from fossil fuels. Continue reading “Buffett’s $1 Billion Order Shows Wind Power Rivals Coal”

When the Weather Channel began promoting “Turbine Cowboys” two months ago, our own Angeli Duffin wrote: “As ratings are critical to any show’s success, we expect ample attention will be given to the dramatic side of the job, but we hope some wind energy education will be mixed in as well.”
Alas, I’m here to report the our educational hopes were not fulfilled, at least not in any significant way. The drama in “Turbine Cowboys,” meanwhile, is mostly of the all-too-familiar Weather Channel junk food variety: Some good footage salted heavily with a repetitive narrative arc, larded with predictable plot turns and then piled high with amped background music and foreboding narration.

This is not to say that “Turbine Cowboys,” beginning a Tuesday night run this week, does not provide some insight into the wind power industry. It’s most profound accomplishment is in bringing home the monstrous scope of the machines, tens of thousands of which now dot the United States, generating close to 3 percent of the electricity we use.
