Study Suggests Generating Capacity of Wind Farms At Large Scales Overestimated

First time accepted submitter AchilleTalon writes "Research by Harvard professor David Keith suggests that the global capacity for energy generation from wind power has been overestimated, and that geophysical / climate effects of turbines will reduce the benefits of large-scale power installations. 'People have often thought there's no upper bound for wind power—that it's one of the most scalable power sources," he says. After all, gusts and breezes don't seem likely to 'run out' on a global scale in the way oil wells might run dry. Yet the latest research suggests that the generating capacity has been overestimated."

    The UK already figured out that wind power claims are exaggerated. By a lot. "Fuel poverty" is now an 'issue' that appears regularly in the UK press. It's killing people.

    Don't believe any of it; they're all oil company shills. Yay saving the planet.

    People have been predicting cheap energy for longer than I can remember. Energy is going to get more expensive, not less.

    The renewables (solar, wind) have fundamental reliability issues. They require an energy storage system, and that energy storage system is expensive.

    Nuclear is expensive too, but for different reasons.

    Oil and coal will likely stay the cheapest energy storage source for a long time to come. In part, because the concrete and steel to make the nuclear plants and the chemicals to make the solar cells come from heavily energy based sources that use oil and/or coal.

    Realistically, investing in different conservation schemes gets way better payback than some renewable energy approaches. It doesn't take much computation to show that switching from always-on incandescent to motion-activated LED light bulbs yields a better return on investment than purchasing solar cells. As gas prices rise and climate change issues increase, North America will simply have to get better at conservation.

    We've got to play the cards we're dealt

    We've long since played cards we've dealt ourselves. That's why there is a vast cloud of pollution drifting out of China. We've feathered our environmental pressure group nest at home and shipped our industry and its energy demands out of "the environment."

    Mexico doesn't have a Feinstein to wreck their solar build outs. For purposes of this discussion Mexico isn't in "the environment" either. It's just another destination for refugee industries evacuating the US.
