Nobel Prize-winning physicist Steven Chu is leading the Lawrence Berkeley National Laboratory's efforts to develop cleaner forms of energy, including new types of solar cells and new biofuels. He answered viewer questions about his research and the future of alternative fuels.
What about conservation? It is far easier to find more efficient ways to use energy than to find more energy. But industry is not interested in this because they will sell less energy.
Steven Chu responds:
I agree that conservation is the most important thing we can do, and it will remain the lowest-hanging fruit for decades! I am the co-chair of an Inter Academy Council (representing 90 academies of sciences around the world) report that should come out in October 2007 on how to transition to sustainable energy. I anticipate that conservation and energy efficiency will be our number one recommendation. However, conservation alone will not solve the problem; we also need new sources of clean energy.
