Dave, you are down-selling the ability of coal miners. They are not idiots, they are people. There will be a lot of earthmoving, concrete work and steel errection before the electricians start work. The panels need to be built and transported and the maintenance work is not just cleaning. People can be re-trained to work at other things.
And “Greenies” as you call them, are people also and from all walks of life. Some are doctors, some are teachers and some are miners. They are people who believe we should leave the world in a better state than it was left to us, so our children and grand chilren don’t have to suffer the consequences of greed from those before them. So they can enjoy a cleaner, safer world and with cheaper electricity. Is there something wrong with that?
