Lets see- using his own numbers lets examine his comment on the minimal contribution of wind and solar despite the hundreds of billions of investment. Fossil fuels - specifically oil and gas - have been around as our dominant source of energy for what- call it a hundred years. If we just look at the last 40 years - the subsidies alone accruing to that industry add up to somewhere in the neighborhood of $16 Trillion USD (40 x $400 B). It is probably also the largest single business sector in the world so the reinvested profits used to build the industry to its current colossal size is say- for the sake of simplicity- 10 times that amount over the past 100 years - USD 160 Tr. That means even a trillion USD invested in renewables over - what- primarily the past 8- 10 years- represents a grand total of somewhere in the neighborhood of 0.7% of the total invested in O/G. Renewables are going to blow O/G away- after all the fuel is free - unlike O/G. And - it will be soon
