Finally, CO2 (in steam reforming of natural gas: 7.05 kg of this gas is produced per kilogram of hydrogen)

We can ballpark it by taking the per capita energy footprint of Canadians4 and multiplying it by the eight billion people in the world, which gives us about 2.4 × 1021 joules per year, roughly ten times the current global energy consumption. That’s the total amount of energy that would be needed each year for every person on the planet to have acce
