At the National Renewable Energy Laboratory’s National Wind Technology Center (NWTC), government scientists and engineers partner with industry and academia to test new renewable energy technologies. In this aerial photo, one engineer examines the interior of a new (large) wind turbine design.

    When one extracts gigawatts from the wind, what happens to weather? To Earth’s rotation? Who hears the bats and the birds when they die?

    Nothing changes.

    I don’t understand why nuclear power has declined.
    Rather than pushing reforms to keep it as safe as the U.S.N. program, it is being abandoned.
    The public hypocrisy is astounding and obtuse. In the century or so that oil alone has been used it has been the cause of at least a half billion deaths in an amazing myriad of ways. The casualties are so many as to be literally incalculable. Most people have been injured in some way by an oil product in their lives.
    Nuclear power has been around about 3/4 that long. Yet even INCLUDING the 2 bombs used it has “only” had around 225k fatalities! Casualties less than 100k. This holds true even extrapolating out to the same years as oil.
    Then there’s coal and it’ harms for even more centuries.
    Nuclear Power adds up to the least harmful per possible gigawatt many times over. Solar, wind, etc. are great but it is as yet unforeseeable as large scale replacement.
    Meanwhile whole cities are shut down for days at a time due to smog…

    @centromere
    Energy, linear and angular momenta must be conserved. Dry air at STP has a density of 1.29 g/liter. Calculate how much air at 20 mph must be reduced to 10 mph to generate one gigawatt continuous. Then tell me that does not bollox weather.

    A single one gigawatt coal-fired power plant burns about 28.5 million pounds of high grade coal/day. Look up the enthalpy of combustion of bituminous coal to deal in conversion efficiency.
