Exactly what happened in the UK with the solar feed-in tariff.
It's not insane because large batteries are environmentally unfriendly. Nobody is disputing that. Of course they are. They're just less environmentally unfriendly than burning petrol.
Batteries might not be eco-friendly, but they are reciclable and meanwhile global warming is the more urgent and grave issue.
The alternative is you are a troll.
And for that matter where does the power for all the electric cars come from?
It's clear that the best ways to combat this issue lie in consuming less (also by creating better lasting /more easily repairable products). Instead poorer countries & people get fucked over due to "green rules" and higher prices in energy.
I don't see how poor people being unable to warm their houses during winter helps save the environment at all. They are part of the environment as well.
As long as people aren't interested in changing their lifestyle and limiting consumption and corporations are only geared towards more profit the environment will turn to ash.
Public transit infrastructure is a much better option for saving the environment and society. Good public transit is such a pleasure to use.
