By the year 2000, such renewable energy sources could provide 40 percent of the global energy budget; by 2025, humanity could obtain 75 percent of its energy from solar resources.

I would love to see a fundamental re-thinking of whether we truly want to be the world's largest debtor nation, feeding an insatiable desire for mall-crawling with cheaply made crap from all over the world.

We need a firm cap on carbon emissions from fossil fuels. No coal, oil, or gas could enter the economy until the buyer had a permit. All permits would be auctioned by the federal government, and the number of permits auctioned would be decreased by three percent per year. Permits could be traded, but they could not be created out of whole cloth by companies that plant forests or dump iron filings at sea.

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.

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.

Obama wants to build such things as smart electrical grids and high-speed rail lines, which will offer big environmental improvements. Another obvious thing is that large-scale project financing is virtually frozen, so a lot of renewable energy projects are on hold. If the system doesn't get unclogged before the developers run out of cash, they will be cancelled. Money matters, and we are racing against time.

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.
