World Peak Uranium Production
Preface. The World Nuclear Association estimates 90 years are left. Today 67,500 tonnes of uranium are consumed a year world-wide and production in 2020 was 47,731 tonnes (WNA 2021). Sounds a bit peakish, thank goodness for stockpiles and the infinite … Continue reading

Utility scale energy storage doesn’t scale up: limits to minerals and geography
Preface. Natural gas is finite, but aside from (pumped) hydropower, natural gas is the main way wind and solar are balanced now. Therefore, a tremendous amount of energy storage will be needed in the future as natural gas declines. And … Continue reading
Pumped Hydro Storage (PHS)
Preface. This is the only commercial way to store energy now (CAES hardly counts with just one plant and salt domes to put more in existing in only 5 states). Though of course hydropower is only in a few states … Continue reading

Hydropower has a very low energy density
To store the energy contained in 1 gallon of gasoline requires over 55,000 gallons to be pumped up 726 feet (CCST 2012). As a thought experiment look at what it would take generate all of America’s 4,058 TWh electricity, where … Continue reading
