Big potential for expansion of wind energy

In my Resources class I show a map of areas suitable for wind energy, but it might be better for me to toss that thing away. New reports show that taller turbines, though more expensive to build and harder to transport, are workable just about everywhere. That's pretty cool on its own, but the even more exciting news is out of developing countries, where 2/3 of power being installed is from renewable sources, including wind and solar. Wow! Hopefully the batteries produced by Tesla and others will make wind increasingly the mainstay of the world's energy supply.
