Another Look at Green Energy
We are seeing a lot of proposals about pollution, global warming, fossil fuels, and alternative energy sources. I think they are all missing the point. The real problem is too many people on the planet using too much energy. The most basic law of physics is the law of conservation of energy. All energy, from whatever source, eventually becomes heat.
If you create electricity from hydroelectric plants, cleaner even than nuclear plants, making the electricity creates heat. Turning the turbines creates heat, running the generators creates heat. Transmitting the electricity through wires creates heat from the electrical resistance. Using the electricity creates heat. For that matter, building the dams, turbines, and generators all create heat and often other environmental pollutants.
It’s an unavoidable law of nature. All energy creation and use makes heat. Reduce the number of people on the planet by maybe 1/2 and most environmental problems are solved.
Wind energy? The bird kill problem would be solved by a different design for windmills. Vertical axis designs have been demonstrated that are more efficient, do not kill birds, and are cheaper to make. Even so, when you build them and their necessary generators and electronics, you create heat and other pollutants.
So the real problem is heat pollution, yes, there is accompanying problems of CO2 emissions, particulate pollution and all of the others. Each of those is possible to solve. But the heat pollution will remain and will continue to get worse until the world population is substantially reduced.
