Sorry, I got into a habit of submit then edit on HN because we used to get errors if you waited to long. I did not think we would hit 10% by 2060, but I hope we hit 40%.

US coal use is down to where it was around 1930. Petroleum is around 1960's usage levels. https://www.eia.gov/todayinenergy/detail.php?id=26912

Natrual gas has spiked, but it's realitvly speaking less of a global warming threat due to C(x) H(x) turning into H20 (x) + C02 (x) which produces less CO2 per heating vs just C into CO2 from coal.

So, while there are a huge range of predictions. What happens in the next 20 years is more important than what's going on 40 - 60 years from now.
