Gregory's Server@davidho One of the advantages of LED streetlights was a reduction in energy consumption. This defeats that.
Electric vehicles don’t save energy: net effort to move mass is the same. Except the energy now comes from a large generator somewhere with generating losses and transmission losses. What generates the electricity? Coal, oil, natural gas? Nuclear? Solar? Wind? Does it pollute as much as a gasoline car with emission controls? System level impact? Think!

@theron29 @davidho And one more question: what is the impact of lithium mining, transport and refining of the lithium, recycling (we hope)of the spent battery pack and replacing it with a new one? @bouriquet @davidho All your questions have answers long since. Pretty clear that @davidho thought more when posting. @bouriquet @davidho research says you're wrong https://mastodon.energy/@janrosenow/112507198471084730 |
@bouriquet @davidho The same goes for ICE cars: How much fuel and electricity had to be burnt for your petrol to get to your local pump? To get cracked in the refinery? Oil to be transported to the refinery? And drilled out of the earth? And your car then throws away at least 60% of that energy away in a super-inefficient combustion engine ! Think!
