Growing climate concerns and commitments to clean energy have done little to curb worldwide oil demand , which in the third quarter of 2019 increased by 1.1 million barrels per day. Experts expect peak oil usage in 2036 , with 70% of daily oil usage in the U.S. going toward transportation alone.

One example is a Russian oil field called Samotlor that once used flooding to push oil closer to the surface—a practice that required 95 barrels of water for every five barrels of oil. Today, that field […]
