Where are we going with electric cars? Are we kidding ourselves if every time... [View all]

we charge out EVs' batteries, that electricity still comes from power plants burning fossil fuels?

Just read that a major hydrogen rail initiative was just abandoned in Germany because battery power/electricity is cheaper. And we aren't even at that point here as many of our rail systems are still diesel.

What are we really doing? Oil/fossil fuels won't last forever, and it's use is slowly...no, rapidly...heating up the planet.

The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

We've got to do better and quickly. How do we get the message across to maga cultists, and Manchin, who vote down every environmental initiatives introduced by progressives?

Hydrogen vehicles already exist, and their emissions are H2O. brush Aug 2023 #27
It's still more efficient to centrally generate with H2 and power EV's Effete Snob Aug 2023 #28
You are dead wrong about emissions, though Effete Snob Aug 2023 #30
