PlanetWatch focuses on mankind's threat to what an astronaut called our planet's "thin film of life", on an expanding population's voracious consumption and waste of resources, and on the need for clean energy alternatives both to reduce dependence on fossil fuels and to reverse our contribution to climate warming.

What's Inside? |
|
It's the fastest growing energy alternative, built quickly and producing electricity at costs near those of coal and gas in some areas. But to bring the power from plains to city we've got to extend the grid. |
|
We've urged Obama and Congress to use stimulus to create clean tech jobs. But this contrarian view says eliminate energy subsidies entirely, because the government has a terrible track record picking winners. |
|
We continualy hear that the nation's electricity grid needs expansion and modernization. But what does that mean?
Here's a primer. |

And they've already produced an economical car with a battery that takes an 80% charge in 15 minutes and will take you 180 miles. As for the Chevrolet Volt: it is running behind schedule and has slipped to 2011. |
|
First build the infrastructure, then the cars. And sell them without batteries. Let's make today's
gas stations will become tomorrow's battery stations, says this entrepreneur. |

The quest to find substitutes for imported oil is causing scientists to take school from Nature, even to the point of getting in bed with bugs -- bugs that can produce -- ready for this? -- crude oil. |

Most of America’s power is produced by coal-fired plants, and power plants account for nearly 40% of United States CO2 emissions. Coal is undeniably a dirty fuel, twice as dirty as natural gas. It spews more CO2 into our atmosphere than all our cars and trucks. And then there’s coal waste: California’s Sen. Boxer pictured the disposal problem for us: “the equivalent of a train of boxcars stretching from Washington, D.C. to Melbourne, Australia.” Over 130 million tons of coal combustion waste is produced in the U.S. every year with nowhere to go – except when it bursts from its containment ponds to engulf hundreds of acres, as it did last December at a Tennessee Valley site. |

One way is that the EPA, moving aggressively under its new chief, Lisa Jackson, will begin issuing over a period of some eighteen months a series of rulings that are expected to impact manufacturing, transportation, and the way utilities generate power. We could witness the most extensive regulatory rule-making spree in decades. |

Over the last few months, we've seen an
explosion in public interest and business investment in substitutes for
fossil fuels. This authoritative article, by an editorial board member of the
New York Times (and a founder of PlanetWatch.org),
offers a survey of what is happening and what holds promise.
