Clean And Expensive



There is a tipping point in the Climate Change debate where clean energy starts competing in price with dirty energy.

Why Solar Is Much More Costly Than Wind or Hydro
no surprise that if environmental costs are considered, renewables—particularly wind power—are a far better bargain than coal power. But it might surprise many that according to a new such analysis, solar power lags far behind wind and even hydroelectric power in its economic impact, at least in the European Union. ........ the economic costs of climate change, pollution, and resource depletion as well as the current capital and operating costs of the power plants ....... a metric ton of emitted carbon dioxide costs around €43 ($55). ...... many of world’s solar panels are manufactured in China, where electricity is very carbon-intensive ...... new coal and natural gas plants in the E.U. have levelized costs of just over €50 ($64) (in 2012 euros) per megawatt-hour (assuming they are running at maximum capacity); onshore wind is around €80 ($102) per megawatt-hour; utility scale solar PV is about €100 ($127); nuclear power is around €90 ($115); and hydropower is as cheap as €10.

Offshoring The Wind Harvesting: Google Wind

Christian Science Monitor: Will Google wind power project harm wildlife? Depends on location.: The mid-Atlantic venture would position wind turbines at least 12 to 15 miles offshore, which means they would not be easily visible from land. ..... 6,000 megawatts .... equivalent to five nuclear power plants .... “It is so much better than each of the wind generators building their own transmission lines all over the seabed.”
Nokia did not start out a cellphone company. Nokia as a company has gone through many incarnations, in fact so many that its founders will not be able to recognize the Nokia of today. Google might have started out as a search engine, but these forays far and wide are welcome. This not only makes corporate sense, but this is also Google being a good citizen. This is Google turning Don't Be Evil into an active verb.
Wall Street Journal: Google’s Wind Project Got Lift From Vail Ski Trip: a planned giant wind farm designed to run 350 miles along the Eastern seaboard .... laying undersea cables to connect the wind turbines to electrical grids on land ..... 1,200 to 2,000 wind turbines
Google Earth. Google TV. Google Car. Google Wind. I say bring it on.
Google Blog: The wind cries transmission: offers a solid financial return ..... both good business and good for the environment ..... equivalent to 60% of the wind energy that was installed in the entire country last year ..... superhighway for clean energy. .... stronger and steadier winds offshore. .... Mid-Atlantic region ..... offers more than 60,000 MW of offshore wind potential in relatively shallow waters that extend miles out to sea. .....
