notyou2 writes "Steve Chu, Nobel prize winner and Director of Lawrence Berkeley National Labs, recently presented a talk at Google. It's a balanced look at all aspects of the energy problem and its effects, from global warming to emerging technologies, and well worth viewing. 'Among America's most serious concerns are (i) national security, which is intimately tied to energy security, (ii) economic competitiveness, and (iii) the environment. These issues transcend our national boundaries and have serious implications for the world. At the core of these problems is need to secure clean, affordable and sustainable sources of energy. Solutions must come from a combination of improvements on both the demand and supply side, and science and technology will be an essential part of the solution. After briefly describing the energy problem, the remainder of the talk will describe areas of research that may lead to transforming technologies.'"
