Green is not just about renewable energy. It's also about creating a new direction for the whole economy. This requires government to step up, not step back, creating the kinds of mission-oriented public organizations that will enable us to tackle climate change - as ambitious as those that got us to the moon. It also requires the financial sector to be less short-term since we know that short-term finance has distorted incentives and directions in areas like biotechnology.

It's important that public funds be spent in research directions that are pushing market frontiers rather than working in existing areas.
