'Water batteries' could store solar and wind power for when it's needed

The San Vicente reservoir in San Diego County stores water from as far away as the Colorado River. Pumping water into a smaller reservoir in the surrounding mountains could store excess solar power until it's needed, when the sun sets. Dan Charles for NPR hide caption

'Water batteries' could store solar and wind power for when it's needed

San Diego has an ambitious plan to store renewable energy, using extra solar power to pump water up a mountain. This old-style "water battery" technology could be set for a revival.

Meet the California farmers awash in Colorado River water, even in a drought

Sprinklers deliver vital Colorado River water to a field of celery in California's Imperial Valley. The Imperial Irrigation District draws enough water from the river each year to cover 470,000 acres with 5 feet of water. Dan Charles for NPR hide caption

Meet the California farmers awash in Colorado River water, even in a drought

A single irrigation district in California, along the Mexican border, takes more water from the Colorado River than all of Arizona and Nevada. It's under pressure to use less.

To fight climate change, and now Russia, too, Zurich turns off natural gas

Zurich is expanding its district heating system, which delivers hot water and steam through underground pipes. With more buildings relying on this system for heat, there's less demand for natural gas. City of Zurich hide caption

To fight climate change, and now Russia, too, Zurich turns off natural gas

Zurich, Switzerland, is shutting down the gas supply to some neighborhoods. Originally aimed at fighting climate change and saving money, it's also a step to cut gas imports from Russia.

How climate change is forcing cities to rebuild stormwater systems

Deep below our city streets lie intricate networks of underground piping built to carry away excess rainfall run off. These stormwater systems mostly go unnoticed until heavy rains overwhelm them, causing streets to flood. Now, with rising rainfall averages in much of the nation, cities need to plan for more water. Guest host Dan Charles talks to climate correspondent Lauren Sommer about the challenges of such planning and why many cities aren't set up to handle the coming rains.

How dairy farmers are cashing in on California's push for cleaner fuel

Big dairy farms are profiting from California's tougher limits on greenhouse emissions. They're getting paid to capture methane from cow manure. But critics say the system subsidizes polluters.

Megadrought fuels debate over whether a flooded canyon should reemerge

In the 1960s, the Bureau of Reclamation built a dam that flooded a celebrated canyon on the Utah-Arizona border. Today, it's known as Lake Powell — the second-largest reservoir in the U.S.

Placebos Vs Parkinson's: The Power Of Joy

Parkinson's disease is a brain disorder that leads to difficulty with walking, balance and coordination. There is currently no cure, but scientists in Pittsburgh, PA have an ambitious plan to develop a treatment based on the placebo effect. NPR science correspondent, Jon Hamilton, tells the story of how this plan came to be. It involves a batch of illegal drugs, the rabies virus, and figuring out what makes a monkey really happy.

The Debate About Pablo Escobar's Hippos

Pablo Escobar had a private zoo at his estate in Colombia, with zebras, giraffes, flamingoes - and four hippopotamuses. After Escobar was killed in 1993, most of the animals were relocated except for the so-called "cocaine hippos." Authorities thought they would die but they did not and now, about a hundred roam near the estate. Conservationists are trying to control their population because they worry about the people and the environment. But some locals like the hippos and a few researchers say the animals should be left alone and are filling an ecological void. The controversy reflects growing debate in ecology about what an invasive species actually is.
