Busting the electric car myth

No, electric cars don't suck down the same amount of energy as gas guzzlers do.

Dear Pablo,

I was excited to hear that Chevy plans to debut an electric car in 2010. But then a discussion with a friend got me thinking: If the electricity used to charge up an electric car is created by burning fossil fuels, is it better to stick with a gas-powered car with good fuel economy?

It’s true that most electric cars get their electricity from the grid, which, in many states, is made up mostly of electricity from coal-fired power plants. In areas where the power comes mostly from hydro, wind or solar, your electric car would be virtually emissions-free. (Any electric-car owner can achieve this by installing a solar carport at home.)

But we can get at your question in a more precise way. The fact is, you can make an apples-to-apples comparison between an electric- and a petroleum-powered car. An electric car doesn’t consume gallons of liquid fuel, so you can’t measure its use of energy in miles per gallon. Similarly, conventional cars don’t run on electricity, so you can’t use miles per kilowatt-hour. So how do you do it?

Climate change denial’s new offensive

Global warming is wreaking devastation, but Big Oil won't give up profits without a planet-destroying fight

If we could see the world with a particularly illuminating set of spectacles, one of its most prominent features at the moment would be a giant carbon bubble, whose bursting someday will make the housing bubble of 2007 look like a lark. As yet — as we shall see — it’s unfortunately largely invisible to us.

In compensation, though, we have some truly beautiful images made possible by new technology. Last month, for instance, NASA updated the most iconic photograph in our civilization’s gallery: “Blue Marble,” originally taken from Apollo 17 in 1972. The spectacular new high-def image shows a picture of the Americas on January 4th, a good day for snapping photos because there weren’t many clouds.

Wind power: Renewable resource, or another corporate scam?

A fascinating new film about one small-town political fight takes on the pseudo-green wind industry

A still from "Windfall"

In telling the story of a small-town political fight over wind power, Laura Israel’s fascinating documentary “Windfall” at first seems like another entry in the long laundry list of post-”Inconvenient Truth” doomsayer environmental films. Indeed, “Windfall” has some of the rural, homespun feeling of Josh Fox’s Oscar-nominated “Gasland,” which helped ignite a national debate over the natural-gas extraction method known as fracking. Israel’s film also offers a direct riposte to Bill Haney’s “The Last Mountain,” in which Robert F. Kennedy Jr. is seen promoting wind power as a clean alternative to the dirty and destructive combination of mountaintop-removal coal mining and coal-generated electricity.

Can saving the Amazon save the planet?

A global carbon market aims to curb emissions and slow climate change by protecting rainforests

LIMA, Peru — International negotiators are closing in on a new solution for combating climate change — and saving the world’s remaining forests.

Global Post

Some 20 percent of all greenhouse-gas emissions now come from deforestation, especially in the lush, green band of tropical rainforest that circles the earth.

That is more than from global transport.

Big government, our one shot against crazy storms

In our age of devastating droughts, wildfires and hurricanes, the federal government is more important than ever

Look back on 2011 and you’ll notice a destructive trail of extreme weather slashing through the year. In Texas, it was the driest year ever recorded. An epic drought there killed half a billion trees, touched off wildfires that burned four million acres, and destroyed or damaged thousands of homes and buildings. The costs to agriculture, particularly the cotton and cattle businesses, are estimated at $5.2 billion — and keep in mind that, in a winter breaking all sorts of records for warmth, the Texas drought is not yet over.

Fracking: The new front of Occupy

In New York, protesters unite to stop the poisonous oil-extraction process before it starts

This is a story about water, the land surrounding it, and the lives it sustains. Clean water should be a right: There is no life without it. New York is what you might call a “water state.” Its rivers and their tributaries only start with the St. Lawrence, the Hudson, the Delaware and the Susquehanna. The best known of its lakes are Great Lakes Erie and Ontario, Lake George and the Finger Lakes. Its brooks, creeksand trout streams are fishermen’s lore.

Far below this rippling wealth there’s a vast, rocky netherworld called the Marcellus Shale. Stretching through southern New York, Pennsylvania, Ohio and West Virginia, the shale contains bubbles of methane, the remains of life that died 400 million years ago. Gas corporations have lusted for the methane in the Marcellus since at least 1967 when one of them plotted with the Atomic Energy Agency to explode a nuclear bomb to unleash it. That idea died, but it’s been reborn in the form of a technology invented by Halliburton Corporation: high-volume horizontal hydraulic fracturing — “fracking” for short.
