An acre of windy prairie could produce between $4,000 and 10,000 worth of electricity per year - which is far more than the value of the land's crop of corn or wheat.

There really wasn't an environmental movement 30 years ago. The Sierra Club national office in 1969 consisted of one full-time volunteer.

Sustainability requires that we demand enduring quality. Steve Strong has a slide presentation pointing out that much of Oxford was built 800 years ago. What are we building today that will be here 800 years from now? If something like that emerged from this recession, it would help justify the hardship so many people are currently experiencing.

I suppose I'd characterize myself as having a faith-based optimism. My faith is parental and Darwinian.

The easiest way to make something cool is to get cool people to do it. Part of this might mean the president has to forget tensions with opponents, or people like Arnold Schwarzenegger who has actually been decent with oil issues. Maybe he needs to pull some of the cool people in and make them model the right behaviors.

Zeroes are important. A million seconds ago was last week. A billion seconds ago, Richard Nixon resigned the presidency. A trillion seconds ago was 30,000 BC, and early humans were using stone tools.

The sunshine that strikes American roads each year contains more energy than all the fossil fuels used by the entire world.

Listen up, you couch potatoes: each recycled beer can saves enough electricity to run a television for three hours.

These are not exhortations from overwrought extremists, but carefully phrased warnings from some of the world's finest scientists.

We got everyone's attention, but we didn't solve any environmental problems.

Asbestos, EMFs, and CFCs have given us a degree of humility. When yesterday's triumph of modern chemistry turns out instead to be today's deadly threat to the global environment, it is legitimate to ask what else we don't know.

When we held the first Earth Day, everyone said it was a success because of the huge turnout. It was probably the largest planned event across the country.

Under communism, prices were not allowed to reflect economic reality. Under capitalism, prices don't reflect ecological reality. In the long run, the capitalist flaw -- if uncorrected -- may prove to be the more catastrophic.

Build high-speed, electrified trains over the most-traveled corridors. It'sreally hard to power carbon-free airplanes, but electrified trains are much easier. We'll be a half century behind the Japanese, but better late than never.

There are a few obvious consequences and perhaps one subtle possibility. One obvious thing is that, to stimulate the economy, President Obama has committed to creating millions of green jobs that will leave a legacy - much as Roosevelt's public works did during the new deal.

I feel more confident than ever that the power to save the planet rests with the individual consumer.

We presently have the technology ... fuel cells, solar cells, hydrogen ... the opportunities are amazing for clean energy.

That said, I'm embarrassed and furious that so many coal-state Democrats in the U.S. Senate are paralyzing international progress to protect the short term interests of a dying industry that ravages the environment from mine to slag heap.

Earth Day gathered up those strands, and dozens more, and knitted them together in the public consciousness as environmental issues. The nation was pretty startled when 20 million people hit the streets. Congress, which had adjourned for the day to go back to its districts, was blown away.

Whether you are buying a car or casting a ballot, choosing a job or planning a family, follow your moral compass. Don't let others define you. Don't let advertisers mold you don't let zealots ensnare you don't let conventional wisdom trap you....you are part of a much larger whole.
