I’m saying that if 2% of sun light is blocked I don’t think it will make much difference. If it does, build the panels 2% bigger.

Note that it will be 2% on everything. Also, crop production, basically all sources of energy on the planet, except nuclear. If all source of renewable energy can be made 2% bigger, why don't we do that today? What's the point of harming our only true source of renewable energy?!?

Because this is an insurance policy to guard against the worst case scenario ?

> except nuclear

> our only true source of renewable energy?!?

These things appear to contradict each other. I also can't understand the logic of "we can't use nuclear power, but please don't stop the rays from nuclear explosions far away from killing us all". If my options are let the sun kill us all, or run a risk of nuclear meltdown here on earth, my vote is firmly in the "block out the sun and run on nuclear power plants" camp.

For scale, Wikipedia says the US has 97,275 megawatts of installed photovoltaic and concentrated solar power capacity combined as of the end of 2020. If you add 2% loss onto that, you lose about 1,945 megawatts.
