edentSolar and batteries can power the world
The article is just wrong. And only mentions energy used for heating in passing. Heating requires MASSIVE amounts of energy.
I should know bc I have a whole house battery and solar system (almost 30 kWh battery and 24kW solar). It keeps the lights on, but not heating. I live in a mild climate.
The reality is that battery/solar requires major quality of life and activity time shifting trade-offs.
I live in a northern climate and I know multiple people who are net zero with solar+basic battery.
Proper insulation and good windows go a very long way. For instance, I set my heat to 66F during the day and 60F at night. When I wake up in the morning, the register is usually still above 60F.
Net zero. But not effectively zero. They sell energy during the day when no one needs it and buy it an night when we all need it. If we all switched to solar and heat pumps there would be blackouts and an energy crisis
Solar generates like 1/10 in the northern countries for half of the year. No batteries currently can solve this.
The problem with global ecological regulations is they never differentiate between countries on the equator or 30th parallel with countries around 60. They expect everyone to only run on sun and wind. It isn't possible. There has to be at least nuclear which is ridiculously expensive.
It's generally not an easy problem to solve otherwise it wouldn't be a problem anymore.
First sensible thing to do is to relax the expectations for countries like Poland that have no good way to compete with other countries energy wise because of geographical location that noone chooses.
It is extremely unfair to treat everyone the same even though every country has different energy resources.
There's a solution that costs less than fossil fuels, but it's a coordination problem and the USA is structurally unable to solve those anymore. I guess the Soviet Union wins the last laugh?
