Do the math ....
Don't imagine I am pro global warming ... not at all ... I am looking at a overall energy picture based on READING information posted by IEA, and Power Magazine etc ...
Do the math ... the total BTU consumption on earth each year is about 1 quintillion BTU, with US responsible for a large percentage. Use whatever percentage of total you choose. Now figure how many Kwh of electricity will be needed to equal the BTU consumption of gasoline and natural gas ... plus add the energy needed to actually mine, build, transport, and install all the electric heaters, cars, charging stations, solar panels, batteries, windmills, trucks, trains, ships, boats, RVs, jet skis, planes, water heaters, stoves, ovens, clothes dryers etc etc etc ... plus build and upgrade transmission lines at $500,000 per tower, and install new power transformers at each substation so you can achieve full 2-way flow of electric power, then cut down, treat and install millions of new poles for millions of miles of new distribution lines ... and estimate any unfavorable weather patterns that green energy is dependent on (sun, wind, water) ... while adding new, non-hackable smart-grid upgrades and getting each state to agree on protocols ... and don't forget the capitalist system is dependent on growth to pay interest on debt, so consumption must increase each year.
And the final number for reaching 'sustainability' is beyond our capability. I mean, an empty heat pump water heater weighs 300 lbs, and is unaffordable by most, impractical for many homes, and almost impossible to lift into attic, or drag into crawlspace, and expensive to repair, replace, and largely difficult to recycle etc, yet is touted as the 'solution' for water heating.
I say the transition will not happen ...  while each day watching new construction build ever-larger buildings, and pour more heat seeking concrete , and car makers building ever-larger vehicles, oblivious to the issue while they shamelessly promote green energy tripe across all media.
Remember, we cut down our rain forest a century ago, and nobody is talking about the issue, except the media bleeds hearts over the rain forest in Brazil.
