Davecbear on Rely on renewable energy sources

Agree with Lobachevsky and Sam that we can't solely rely on renewables. Yes renewables are a very important opportunity and part of the solution. But deliverying significant supplies of energy to offset the ongoing depletion of existing resources will take investment in renewables, very significant investment in traditional energy sources, and development of new technology that makes coal and other resources acceptable from a environmental standpoint. On top of that efficiency improvements and conservation initiatives from all of us will be key to meeting our energy needs, addressing climate change and providing the economic growth and standards of living throughout the world that people aspire to.
