If solar energy projects could replace fossil-fuel use, and growth could be stopped, and per-capita energy use could be reduced, that would slow, or stop, the increase of carbon emissions.
- stopping growth - no one in power is even discussing it
- reduced energy use - no one in power is even discussing it
- replacing fossil-fuel - fossil-fuels have higher return on energy invested, as long as there is demand, every joule of fossil-fuel saved in one place by solar will be burned somewhere else
- stopping carbon emissions is too little too late
Which leaves a big problem. Many people believe that humans can convert to solar energy and save our species. These people are not getting involved in real solutions. They are waiting for a technological breakthrough. This is deadly.
