No. The current status of renewable energy (geothermal, hydroelectric, wind, solar, etc.) can in no way support our current consumption habits.
Can a more widely implemented renewable energy/less-polluting energy infrastructure support a society that uses less energy? Likely. Or some of us are going to have to die to make room for the bigger consumers lest we all die.
The plan?
(1) Assume all fossil-fuel-burning energy plants will shut down in 50 years.
(2) Begin plans to install the most regionally appropriate renewable energy power plants to support those areas.
(3) Calculate the energy shortfalls and make plans to supplement with the most reasonable nuclear options (insert arguments about recycling waste, using thorium, etc.)
(4) Select a demo site, implement, learn, discuss, implement better.
