...Affordable, carbon-free energy available around the clock is the Holy Grail in a world that aspires to cut greenhouse-gas output even as it uses ever more electricity. Solar power can't provide it; nor can wind. And while nuclear power could do so, many Australians oppose...
...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...
...driven generators on the hottest days of the year," says Lee Schipper of the University of California, Berkeley. Schipper estimates the cost of peak usage is 20 cents per kW-h, as opposed to an average of 13 cents for "baseload capacity" usage, and it is far more carbon-intense because it is generated...
...believes in global warming but is skeptical of its severity - fighting climate change just isn't a good way to spend our money. We know for certain that supplying vitamins to impoverished children will save lives - but we don't know for sure that spending billions to reduce carbon emissions will have the same clear effect. One is a sure thing, and the other is a bit of a gamble - and since the world has limited resources for doing good, the thinking goes, best to opt for the sure thing when lives are at stake. It's a position that...
...what if instead of running your car on gasoline, you could run it on pure electricity? Not only would that help the environment - one-third of U.S. carbon emissions come from cars and trucks - but in an era of ever-increasing gas prices, it would help your wallet as well. Unfortunately, the auto industry has consistently failed to build and sell a truly marketable electric car. They were either too expensive or too weak on the road - or too often both; and back in those halcyon days when our chief climate fear was a new ice age, low gas prices...
