Sunil Paul has a great blog entry about how he chose to get involved with environmental technology companies first and foremost to help “green” the world, and only secondarily to make profit. The profits, of course, followed.

My favorite paragraph:

But it doesn’t have to be a choice between social and economic goals. Clean energy is like the love child of John Muir and Adam Smith. It joins environmentalism with capitalism. Cleantech companies have great value not captured by the price of the good or service. Their entire business model generates excess social return. In addition, the energy market is huge, and is ripe for change – and so the opportunity for profits is tremendous.
