Hard Solar Realities in Puerto Rico

Very readable and informative. Obviously, there is more to consider, but yours is a good start. One typical unknowable: there are only about 4 or 5 countries with proven, sizable lithium reserves that we know of. If many countries begin building massive, utility-sized lithium battery banks, how soon before those reserves run out? Another unknowable: how well would 140,000 acres of solar farms have survived the hurricanes in Puerto Rico? A tree limb through a solar panel renders it pretty much useless and beyond repair. And solar farms in places with snowy winters are quite likely to produce no power just when the population most needs home heating.

A recent winter in Scotland, after they switched nearly entirely to wind power, was particularly cold, and during a fortnight when the wind didn’t blow at all, a lot of homes would have frozen if Scotland hadn’t been able to buy French nuclear power.

Anyone who thinks green energy is a done deal just hasn’t really thought it through. Most likely, green energy will be a supplement sitting alongside a sound system of conventional power sources. Germany is now building new coal fired power plants again.

I have yet to see any realistic appraisal of the economics of small, modular thorium nuclear energy. There are a great many advantages over uranium reactors, but I haven’t seen any analysis take thorium seriously.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
