Artificial intelligence has caused concern for its tremendous consumption of water and power. But scientists are also experimenting with ways that AI can help people and businesses use energy more efficiently and pollute less.

Data centers needed to fuel AI accounted for about 1.5% of the world's electricity consumption last year, and those facilities' energy consumption is predicted to more than double by 2030, according to the International Energy Agency. That increase could lead to burning more fossil fuels such as coal and gas, which release greenhouse gases that contribute to warming temperatures, sea level rise and extreme weather.
