...year loan for the $64,500 system. Yes, his $550 loan payment is more than the $300 or so he used to spend each month on electricity bills--so far, he has generated enough solar power that he doesn't need to take any juice from the grid--but after he pays off the loan, his power will be free. And this year, he'll get a $16,000 rebate in the form of federal and state tax incentives for solar. "I really wouldn't have been able to do this without the financing," he says. "But with [the loan...
...prices at near-record levels and the rush on to find safe, clean sources of energy, news of leaks at two different French nuclear sites could not have come at a worse time. Concern over the incidents is rekindling questions about the safety of France's giant nuclear power grid and could complicate the country's quest to become the world's leading purveyor of nuclear technology...
...There are some obvious challenges. Power from coal-fired plants is cheaper. And the closest connection point to the national electricity grid is 500 km away. But Grove-White says geothermal power will become economic once coal and gas plants have to pay for their carbon emissions, which he expects to happen in an Australian carbon-trading scheme due to start in 2010. While the transmission lines will be expensive, their cost - $500 million or more - is included in the business model...
...that's still pretty egregious. We used an estimated 4 quadrillion British thermal units on air-conditioning in 2006, which is more than the total energy usage of all but 21 countries. And a fair amount of that is peak usage - the sort that sends the electric grid crackling toward brownouts and meltdowns and increases the demand for the construction of more electric power plants (and the pollution they spew - unless they use renewable sources like hydropower or, as John McCain correctly insists, nuclear power, which should be carefully reconsidered). "A lot of utilities supplement their main power sources with...
...system itself is the “safety net” intended to provide power during the few minutes the electrical power grid may suddenly fail, according to Harvard Computer Society president Joshua A. Kroll ’09. The system also provides a “blip in power” if officials briefly shut down the data center for electrical work, he said...
