GM looks jealously at the government subsidies that Tesla has received. That is what it is all about.
Relative to the efficiency of electric cars they are no more efficient than a diesel engine. Yes I said that. A diesel engine is about 35% efficient. A lithium ion battery and the electric motor is about 95% efficient or better.
From the burning of coal or natural gas at the generating station you will lose about 63% of the energy. The biggest energy loss is at the generating station. Most of that energy goes up the smokestack. A typical power plant converts about 37% of the energy of the coal or natural gas into electricity. The losses of energy from the battery to the electric motors is only a few percent depending on the efficiency of the electric motor.
Point being an electric car is not one damn bit more energy efficient than a modern diesel or gasoline engine. They burn just as much hydrocarbons.
Entropy always wins.
Electric cars butn the same amount of hydrocabons as every other vehicle. - thank you. just one correction, in the rankine cycle, nuke plants arent any better, most of the heat goes out the condenser to the cooling towers or whatever body of water they use, in the form of latent heat of condensation. 37% efficiency is a good number for most steam cycles.
Indeed. Both GM and Tesla survive by sucking off the government teat. And they want more.
Meanwhile, the electric car only survives because of government mandates and subsidies. Entropy laughs at our fantasies while our pocketbooks empty.
GM has almost used up their federal tax credit quota like Tesla. No wonder they want the government to mandate..
