“Renewable” has nothing to do with paying for anything. “Renewable” means that the supply is infinite. Yes, you have to pay for a solar panel. And you have to pay for a wind turbine. But if you own these, the energy you get from them is free. If you have to get your energy from somebody else’s wind turbine or solar panels, that person or party will probably charge you for it.
However, the sun is inexhaustible. So is the wind. If you use a lot of solar energy, the sun isn’t going to burn out. Fossil fuels are finite (and therefore not renewable), in that the planet has a limited amount of them. Why in the world does this need to be explained to you? I don’t like to call people stupid, but you’re making it very difficult not to, as your cognitive abilities appear to be sub-par.
Do you pay attention to anything that isn’t part of your little narrative bubble?
Not that it matters. Coal is on its way out. Renewable energies are on their way in. And there’s nothing you can do about it.
