An Electric Vehicle company is claiming that their electric school buses are “sending energy back to the grid to help conserve and reduce emissions.” They do nothing of the sort. All they are doing is returning a portion of the energy that they used in being charged back to the grid.
Energy is not created or destroyed, it merely changes form. In changing form, some of that energy is converted to heat, and is thus lost. Charging the bus causes losses as the batteries heat up. When the busses discharge into the grid, more energy is lost. Then the bus has to be charged again in order to be driven, meaning that even more energy is lost.
I don’t know if the left is stupid or thinks we are. On second thought, perhaps it is the left who is stupid, because they actually believe that it is possible to have perpetual motion devices. I guess arts majors don’t know anything about the First Law of Thermodynamics.
