Wind power is booming. Giant, steely turbines now provide 6% of the United States' electricity. 13,000 megawatts worth of wind power—enough to power around 10 million homes—was installed stateside in 2012 alone. Which is huge. Literally. Typical wind turbines now stand at a height of 300-350 feet tall. They're gargantuan and expensive, and the most efficient can now produce over 6.5 megawatts of power alone.

Small-scale wind turbines [SWTs] are nothing new, after all, and farmers and rural landowners have been taking advantage of them for decades. But they've played a meager role in the recent clean energy renaissance because they're less efficient than their hulking brothers. read more>>>
