He talked about how the government is now aiming toward a 100% renewable electricity supply by 2050. The press release on this from the agency (from almost two years ago now) quotes Flasbarth as saying that “The results of the study demonstrate that electricity supply can be generated completely from renewable energies by 2050 and that secure supply can be guaranteed at all times.”
Feasible? It’s already well in train. In fact, solar PV penetration into the German electric markets is already lowering the price for wholesale electric power at the hours of peak demand by 40% from only very recently. This recent item from Renew Economy lays out how this is being accomplished. I asked President Flasbarth to comment on this and he confirmed that this was indeed the case. Prices during peak demand hours, as you know, have traditionally been way above the average for the rest of the day. Solar PV is standing this paradigm on its head. You have high demand on hot sunny days – largely because of air conditioning. But, you are also going to have the highest boost from PV during that same time under those same conditions. Ergo, with sufficient PV capacity installed, you are going to be able to supply more-than-enough peak power to offset demand and lower prices.
Germany has only a few rivers and mediocre wind, little coastline and shitty sun yet they can go sustainable. Meanwhile with vast swaths of land with intense sunlight, lots of wind and every other resource available, the U.S. has no such aspirations.
