We are being faced with cheap electricity, where even the public can generate their own electricity, but now we come to the era that, it is not constant, it is difficult to store, as hot water, battery energy, hot liquid salt, even hot sand to hold energy, until we can turn the water into steam energy, so now we need efficiency. When the oil companies were in charge, they wanted waste & pollution, they made money that way, but the supply was limited. With efficiency, everything works better.
