Batteries do not create energy. They store energy. That energy must come from somewhere, and in America, that's usually coal.

Over 60% of US energy comes from coal & natural gas. ABout 20% comes from nuclear.

The second law of thermodynamics (among others), proves that charging batteries is done at a loss. Any time you convert from one form of energy to another there is a loss.

Even ICE engines converting exothermic reactions into torque is at a loss.

Batteries are cool for storing energy for times when direct energy isn't available, but are an otherwise terrible way to use as a utility. People think they are saving the planet because they convert coal and diesel (at a loss) into stored DC current, then convert that (at a loss) to AC current, or to torque.

Battery / e-vehicles might make more sense if an entire country's power grid is powered by natural /renewable resources. Then again, no one has studies what impact large solar farms, harnessing natural flow of water, and slowing wind movement has on the earth. It may be far worse.

edit: in b4 2nd law is about flow of energy form high concentration to low concentration, it also deals with the realism of entropy.

Anyone who works in electronics knows there's losses every step of the way. Transmission, batteries, creation, usage, and so on. ICE engine are horridly inefficient, but they are powerful and portable.

Batteries are good for when the grid goes down. They allow you to get your off-grid power online while everything is still running. In a collapsing empire, this is an important consideration. They're also required for solar energy systems, the grid-tied ones are jewish dogshit that do nothing when it goes down.

I just want to reduce my damn bills. It might end up being worth it to get a nice solar setup going.
Plus at the end of the world, you'd have electricity still (at least some).

By all means, if you can do it, yes! The concept of an e-car is a net loss. Not to mention children mining lithium and the huge environmental disaster we will have when All the ev's have batteries to dispose of.

Harnessing wind and solar for a home, is nothing like "farms" that drastically affect weather patterns.

I wish you success.
