Energy Problems? What Energy Problems?
If you realize that the annual influx of solar irradiation has a larger energy content than all fossil and nuclear energy cumulatively consumed in history; if you realize that thin film solar has an EROI of ca. 35, than you know that once the energy storage problem has been solved, as it will be solved since the entire world is working on it, the world’s energy problem will have been solved as well and with it a lot a climate problems.

The yellow area represents the magnitude of annual solar energy reaching earth. It is larger than the cumulative energy contained in all fossil and nuclear energy consumed throughout human history. An area the size of Spain plastered with solar panels would suffice to replace all energy consumed globally today. It can be done.
