...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...
...will actually create millions of new jobs. Someone, after all, will need to produce alternative power, increase energy efficiency and overhaul wasteful buildings. Angelides notes that between now and 2030, 75% of the buildings in the U.S. will either be new or substantially rehabilitated. Our inefficient, dangerously unstable electrical grid will need to be overhauled. The jobs that will go into that kind of work can be green-collar - provided that the government adopts the kind of policies that incentivize environmentally friendly choices. "Green jobs won't be sprouting up only in new technology fields" like solar energy, says Angelides...
