>Germany installed a lot of solar panels over the last decade but carbon emissions have not changed and electricity bills have increased.
>Germany is now digging up, buying and burning lignite, the shittiest type of coal, to avoid rolling blackouts.
>The reason is very simple, Germany is a country that gets a lot of clouds and not a lot of sunlight.
Are there any complete, rigorous maps of the parts of the world where solar panels are actually useful? Deserts and plains obviously, but you can't just put solar panels everywhere, because some of that sunlight is already being used for crops.

So what happens if by 2050 (((peak oil))), we haven't invented fusion power or any improvements to solar beyond what we have today?
