A recent analysis in Renewables International magazine explains in no more than two graphs the reason the fossil fuel industry has been battling solar power for so many years.
The first graph here (with a little editorial added) is the price of electricity on a given day in Germany four years ago when Germany mainly used coal and other fossil fuels to produce electricity:
This second graph shows the price of electricity on a given day now that Germany uses a ton of solar power during the day to produce electricity:
Now I am no economist, or even that good with money in general, but that big giant dip during the day looks to me to be a whole lot of money being saved on electricity production.
In other words, goodbye big fat profits to coal companies, and in the long run, big fat savings for all of us.
Then of course there's all those niggly other details like the fact that power from the sun is clean, unlimited and doesn't contribute to climate change or lung cancer.
