Since 1980, wind energy costs have fallen by more than a factor of 20 in some regions of the country — going from more than 55 cents per kilowatt-hour to  – Current standard height for most wind turbines is 80 m, however heights of up to 120 m are already common in parts of Europe. US Energy Department is working with wind turbine manufacturers to develop new turbines that stand 110 to 140 m tall – potential for wind deployment in U.S. increases by 54%, rising another 13% to 67% at 140m height – report finds increase in wind power to provide 20% of the country’s electricity production by 2030 would provide estimated annual benefit of $30 billion in 2030 from air pollution and greenhouse gas emissions reductions. The industry could also account for around 400,000 jobs by 2030 and provide billions of dollars annually in property tax payments.
