(Most Teslas are powered by fossil fuels today via the grid, not renewables. 80% of US energy is still non-renewable and non-nuclear.)
- xxpor 5y agoIs that what OP meant by fossil fuel? Fixing the source of electricity is (probably) a lot easier than fixing the source of hydrogen itself.
- Robotbeat 5y agoIf by “energy” you meant “electricity” (which is the only thing that makes sense given context), that is incorrect. The US electrical grid is about 40% clean (half being renewable and the other nuclear). Coal is 19% and falling. The rest natural gas. But even on natural gas, Teslas are more efficient than conventional cars. This is NOT true for hydrogen. Making electrolytic hydrogen from existing grid energy is not better than a good hybrid in terms of overall efficiency. The “but electric cars still use the grid which has a lot of fossil fuel production” argument is actually compounded for hydrogen cars as they require over twice the electricity input to achieve the same distance traveled as battery electric.
