Clean energy breakthroughs depend on significant government research and development funding, agreed public policy, business, and academic leaders at the University of California at Berkeley\u2019s second annual Energy Symposium earlier this month. Without enough, the shift to clean energy could fall short or \u201ccrash.\u201d \u201cWe\u2019re at a very critical cusp in time,\u201d said David Sandalow, Brookings Institution senior fellow. \u201cThere is no magic bullet for adapting to global warming because the impacts are so wide ranging.\u201d Financiers seemed to agree. \u201cIf we go on as business-as-usual, the Arctic ice cap will melt in 5 years,\u201d said John Doerr, partner at the venture capital fund Kleiner Perkins Caufield & Byers. \u201cThe best way we can predict the future is to invent it. The second best way is to fund it.\u201d He added that \u201conly $1 billion of federal R&D are designated for renewables. The federal geothermal budget was only $5 million. This is criminal for investment R&D.\u201d Moreover, research and development funding is not seen as stable enough to \u201censure predictability for policy-makers, which is critical to nurture the innovation,\u201d said Mitch Zuklie, law firm partner at Orrick, Herrington & Sutcliffe. -Allison Loomis Editors\u2019 note: For a more detailed version of this story, please see our sister publication E=MC2 \u2013 Energy Meets Climate Challenge--energymeetsclimate.com.
