Here is the vision for our zero-carbon future: Everybody will get around in electric cars. And all the electricity to run those cars will come from renewable sources, like solar and wind, both as good as zero carbon, once you start manufacturing them using energy from solar cells or windmills that you've already built.
Great idea, right?
Another source of renewable energy, hydropower, already provides more than 6 percent of the electricity consumed in the United States in 2015. They were built in a gung-ho time: first their construction gave lots of jobs. Once they were finished, they supplied electricity to growing cities as well as water to both cities and agricultural users. Not to mention the opportunity for water sports, in all those places that would normally not have enough water for a row boat, never mind yachts and water skis.
People love dams. But oddly enough, people don't love wind parks.
That's too bad, because wind is actually one of the most promising sources of clean energy. Already, at 60,000 megawatt (MW) installed capacity, it supplies 4 percent of the electricity used in the nation, and it's growing by leaps and bounds.
Back in 2008 wind already generated 52,000 gigawatt-hours of energy. A gigawatt (GW) is a billion Watts. But those 52,000 GWh is a tiny fraction of how much energy could potentially be generated by wind in the US: That number is mind-bogglingly large: 37,000,000 GWh, or 30 times the nation's entire current electricity consumption. Conveniently, the wind potential is reasonably well-distributed, peaking over a broad swath of the midwestern states as well as at the coasts.
So why aren't we buliding wind parks like mad?
