In 100 years our descendants will not be burning coal, oil, natural gas or using nuclear fission.  They might be using terrestrial nuclear fusion.  They will be using solar, wind, geothermal, marine current hydro, tidal energy systems – clean, renewable, sustainable energy systems. No fuel: No Waste. No mines, mills, wells, spills. No arsenic, lead, mercury, selenium, thorium – no fly ash to be contained or to leak.

We have started.  California and New Jersey lead the U. S. Germany and Spain lead Europe. Boeing and Richard Branson’s Virgin Atlantic want to build aircraft that run on biodiesel.  We need to move forward in a big way – to 100% clean energy in 10 years, to retrain coal miners and oil rig operators to build and run solar arrays and wind turbines, and dig deep geothermal systems.
