For a quick logical analysis of going “totally renewables”/electric, I propose doing the following… in the United States the government publishes yearly consumption numbers of petroleum products, (diesel fuel, gasoline, propane, natural gas..) and yearly coal consumption. These all have established BTU values, multiply the quantities by the btu’s, then using a conservative estimate of 40% of these btu’s being put to work (engines being less efficient, direct burn for heating applications being much more) convert this 40% number to KWH (divide by 3412) of electrical need to replace it and see the ENORMOUS scale of upgrade needed to do it. It truly is huge, not just on production but distribution, then add in the extra energy needed for the materials to make this upgrade (aluminum production for bigger transmission wires uses a lot of electricity), copper for the needed transformers to distribute it exceeds the global available resources, the transmission losses (and losses in charging/discharging batteries adds more load requirements).. I think you can get where I’m going with this. 20 minutes of back of the envelope calculations show there is a snowballs chance in…someplace.. of actually working at current consumption levels. Even if the green generating source was available (which it isn’t). Nuclear, maybe, if done right, but nobody seems to ever want to talk about it being the single viable generation source that could replace fossil fuels.
