Beyond Wind and Solar: What Are Our Real Options?: Solar power and wind power are usually the first topics tha...

Solar power and wind power are usually the first topics that come to mind when the discussion turns to renewable energy sources. The global solar footprint has grown almost a hundredfold, from 175 megawatts in 2000 to 15 gigawatts in 2010 . But despite the growth of those sectors, wind and solar still account only for a tiny fraction of global electrical generation, which is dominated by coal, natural gas and nuclear power. Conventional hydroelectric power currently provides about seven percent of the electricity in the United States. But the lack of new sites and tight environmental regulations ensure that there won't be a lot of growth in large hydro -- never mind the efforts to dismantle existing dams to restore fisheries. But dams are not the only way to harness hydro power. Startups are innovating and looking to use wave power, tidal power and power from river current...
