A New Hydropower Boom Uses Pumped Storage, Not Giant Dams

Media Library

For a century, hydroelectric power has been synonymous with gigantic dams — feats of engineering that provide renewable energy but displace communities and destroy ecosystems. New research released Tuesday by Global Energy Monitor reveals a transformation underway in hydroelectric projects — using the same gravitational qualities of water, but typically without building large, traditional dams like the Hoover in the American West or Three Gorges in China. Instead, a technology called pumped storage is rapidly expanding. These systems involve two reservoirs: one on top of a hill and another at…

China’s Record Drought is Drying Rivers and Feeding Its Coal Habit

Chin@Strategy

HONG KONG — Car assembly plants and electronics factories in southwestern China have closed for lack of power. Owners of electric cars are waiting overnight at charging stations to recharge their vehicles. Rivers are so low there that ships can no longer carry supplies. A record-setting drought and an 11-week heat wave are causing broad disruption in a region that depends on dams for more than three-quarters of its electricity generation. The factory shutdowns and logistical delays are hindering China’s efforts to revive its economy as the country’s leader, Xi…

Drought Hurts China’s Economy as Central Bank Cuts Rates

Chin@Strategy

HONG KONG — Record-high temperatures and a severe drought in west-central China have crippled hydropower generation and prompted the shutdown of many factories there, in the latest blow to a Chinese economy that already has stagnant consumer spending and a deeply troubled real estate market. Sichuan Province in west-central China, one of China’s most populous and a fast-growing industrial base in recent years, normally generates more than three-quarters of its electricity from huge dams. The summer rainy season usually brings so much water that Sichuan sends much of its hydropower…
