Status quo: Right now the US could satisfy one third of their total energy needs with power generated with wind turbines.
Now the Japanese found a way to triple the energy output of wind turbines.
So it becomes possible and even cheaper to live from wind power. Not to mention water and solar energy or even coal to fill additional gaps.

QUOTE said:Imagine: no more dirty coal power, no more mining deaths, no more nuclear disasters, no more polluted aquifers as a result of fracking. Our entire society powered by the quiet "woosh" of a wind turbine. Kyushu University's wind lens turbine is one example of the many innovations happening right now that could in the near future make this utopian vision a reality.
Yes, it's a heck of a lot of wind turbines (about 2,640,000) but the U.S. with its endless miles of prairie and agricultural land is one of the few nations that could actually deploy such a network of wind turbines without disrupting the current productivity of the land (Russia and China also come to mind). it would also be a win-win for states in the highest wind area — the Midwest — which has been hard hit by the recession. And think of the millions upon millions of jobs that would be created building a 21st century energy distribution system free of the shackles of ever-diminishing fossil fuel supplies.
It's also important to point out that growth in wind power capacity is perfectly symbiotic with projected growth in electric vehicles. EV battery packs can soak up wind power produced during the night, helping to equalize the curve of daytime energy demand. So the controversial investment currently being entertained by President Obama to pipe oil down from the Canadian Tar Sands would — in my utopian vision — be a moot point.

QUOTEThe International Clean Energy Analysis (ICEA) gateway estimates that the U.S. possess 2.2 million km2 of high wind potential (Class 3-7 winds) — about 850,000 square miles of land that could yield high levels of wind energy. This makes the U.S. something of a Saudi Arabia for wind energy, ranked third in the world for total wind energy potential.
Let's say we developed just 20 percent of those wind resources — 170,000 square miles (440,000 km2) or an area roughly 1/4 the size of Alaska — we could produce a whopping 8.7 billion megawatt hour's of electricity each year (based on a theoretical conversion of six 1.5 MW turbines per km2 and an average output of 25 percent. (1.5 MW x 365 days x 24 hrs x 25% = 3,285 MWh's).
The United States uses about 26.6 billion MWh's, so at the above rate we could satisfy a full one-third of our total annual energy needs. (Of course this assumes the concurrent deployment of a nationwide Smart Grid that could store and disburse the variable sources of wind power as needed using a variety of technologies — gas or coal peaking, utility scale storage via batteries or fly-wheels, etc).
Now what if a breakthrough came along that potentially tripled the energy output of those turbines? You see where I'm going. We could in theory supply the TOTAL annual energy needs of the U.S. simply by exploiting 20 percent of our available wind resources. Well such a breakthrough has been made, and it's called the "wind lens."
