The underlying struggle - between worlds of plenty and worlds of want; between the modern and the ancient; between those who embrace our teeming, colliding, irksome diversity, while still insisting on a set of values that binds us together, and those who would seek, under whatever flag or slogan or sacred text, a certainty and simplification that justifies cruelty toward those not like us.

We need scientists to design new fuels. We need farmers to help grow them. We need engineers to invent new technologies. We need entrepreneurs to sell those technologies. We need workers to operate assembly lines that hum with high-tech, zero-carbon components. We need builders to hammer into place the foundations for a clean energy age. We need diplomats and businessmen and women, and Peace Corps volunteers to help developing nations skip past the dirty phase of development and transition to sustainable sources of energy. In other words, we need you.
