You can't run an electrical grid on wind and solar alone and expect it to be stable enough. - The prospect of every household having a battery backup big enough to smooth over spikes and dips is ludicrously wasteful. We are already struggling just mining enough to make batteries for cars and phones. - the sheer scale of the wind and solar farms will leave major environmental impact to wildlife. Look at how massive area solar farms need, and know the area has to be cleared and desolate of life.

Nope, simply untrue. Cars use lithium ion batteries mainly for their energy density. For grid storage, other batteries and ways of storing energy are feasible and probably a lot cheaper as well. Wikipedia has a nice overview: https://en.wikipedia.org/wiki/Grid_energy_storage#Grid-oriented_battery_technologies https://en.wikipedia.org/wiki/Grid_energy_storage#Grid-orien... The wild life impact of solar is relatively minor compared to burning coal, intensive farming, and all the other things we do. We'd need to only cover a relatively small amount of land with solar to produce what we need. And ironically some of the most suitable land for this would be deserts that have relatively little wild life to begin with. Of course the impact of wiping out coal, gas, and petrol usage would be enormously positive. Windmills do indeed kill some birds. Yet, these things seem to have barely any impact on e.g. the seagull populations in places like Denmark that have a ridiculous amount of wind mills.
