Solar Panel Sales
When, what year, do you expect gasoline sales to End, Stop?
The first part to fight GW is to end burning coal, oil and trees.
The second part is to switch to renewable energy sources, like windmills, Solar Panels and Hydrogen from water.
Both parts must be carried out together, to avoid an economic disaster.
According to a study done by eminent scientist and writer Jerry Pournelle, the resource window will close on Humanity in 2035. That means, world population will have outgrown available resources so that there is less instead of more from that point forward. I suspect that unless the Arctic oilfields recently revealed in Canada are totally exploited, we won't have enough gas to move a single car by 2030 or thereabouts.
