Agreed, we should instead focus our technologies and intelligentisia on harnessing the tremendous energies of the Sun, Sea and Earth before anything else, especially before energy sources that pollute our planet for hundreds of thousands of years (for some nuclear fission waste several million, in comparison homo sapiens have only existed for a few hundred thousand years).
Hydroelectric dams, windmills, geo- and solarthermal energy, etc. already many nations get about 10-15% of their energy from these sources, and some much more:
About 81 percent of total primary energy supply in Iceland is derived from domestically produced renewable energy sources. In 2007, geothermal energy provided about 66 percent of primary energy, the share of hydropower was 15 percent, and fossil fuels (mainly oil) 19 percent.[1] The main use of geothermal energy is for space heating with the heat being distributed to buildings through extensive district-heating systems.[1] About 85% of all houses in Iceland are heated with geothermal energy.[2]
Renewable energy provides 100 percent of electricity production, with about 70 percent coming from hydropower and 30 percent from geothermal power.[1] Most of the hydropower plants are owned by Landsvirkjun (the National Power Company) which is the main supplier of electricity in Iceland.[2]
