So the cost of energy is a complex topic and this guy has studied many aspects of that.
Amongst other things he wrote : Morgan, Tim (2013).Life After Growth. Petersfield, UK: Harriman House. ISBN 9780857193391
He discusses the energy cost of energy or : Energy return on investment
He gives an estimate of $130 trillion usd for the global cost of energy transition with a link to the source… I don’t understand how this estimate is made though.
