Because of the industrialization of agriculture — using massive amounts of fossil fuel — only 2 percent of Americans work in farming. And yet they produce enough food to feed all 300 million Americans, with plenty left over for export. When are liberals going to break the news to their friends in Darfur that they all have to starve to death to save the planet?

If an aircraft is able to fly day and night without fuel, propelled only by solar energy, let no one claim that it is impossible to do the same thing for motor vehicles, heating and air-conditioning systems or computers, etc. This project voices our conviction that a pioneering spirit with political vision can together change society and and reduce society’s dependence on fossil energies.

I think that so far the political and economic power of the fossil fuel industry has trumped all else.

Renewable energy is far more labor-intensive than fossil fuel production.

We’re going to need that kind of movement, because the fossil fuel industry is a sprawling adversary – at work everywhere, its tentacles in everybody’s politics, invulnerable, I think, to direct frontal assault, but probably more brittle than it guesses if we come at it from all sides.

I think the world on the other side of fossil fuel is more local – the logic of sun and wind is diffuse and spread out, not concentrated like the logic of coal and oil.
