Can we grow enough food postcarbon? Irrigation needs water & electricity
Preface. Irrigated agriculture over 58 million acres consumes the largest share of U.S. water. And it’s shrinking as aquifers are drained, reservoirs evaporate, and drought reduces snowpack and rainfall at the same time population and the economy are growing. My … Continue reading

USGS Groundwater Depletion study of aquifer decline in the U.S.
Preface. I summarize two major research papers on the state of the Ogallal below. It and many other aquifers are depleting rapidly, and polluted from pesticides, feedlot waste, intruding salts, and other pollution. Rainfall isn’t replenishing the Ogallala. Many won’t … Continue reading

Aquifer decline in California
Preface. On top of aquifer depletion, water shortages in California are also expected in the future as rainfall and snowfall decline and snow melts earlier. Over half of Americans rely on underground aquifers for drinking water (Glennon 2002). Seventy percent … Continue reading

Compressed air energy storage (CAES)
Preface. Besides pumped hydro storage (PHS), which provides 99% of energy storage today, CAES is the only other commercially proven energy storage technology that can provide large-scale (over 100 MW) energy storage. But there are just two CAES plants in … Continue reading

California’s central valley aquifers may be gone in 2030s, Ogallala 2050-2070
Preface. Clearly the human population isn’t going to reach 10 billion or more. California grows one-third of the nation’s food, the 10 high-plains states over the Ogallala about a quarter of the nations food, and exports a great deal of … Continue reading
