Wave power

Wave power

The first ocean wave energy-capturing device with a permit to connect back to a public power grid will enter the Pacific next month. How much power could the U.S. potentially harness from the waves crashing into its the coastline? According to researchers, wave energy might be one of our best renewable resources. More »

Fracking

Fracking

Classroom Activity Page: Hydraulic fracturing, or fracking, is a high-pressure technique for cracking rocks and allowing natural gas to reach wells. Amid a boom in U.S. natural gas production, industry promises that fracking will bring Americans jobs and low-cost energy for decades. Opponents warn that the drilling-and-fracking process threatens to pollute air, surface water, and most importantly, groundwater. Will these concerns stymie an ongoing boom in natural gas production? Should they? More »

Mourning the dying weather satellites

Mourning the dying weather satellites

We love accurate weather forecasts, but the weather satellites they rely on are nearing the boneyard. Some replacements have crashed into the ocean, others are in financial limbo. Be very worried about our fragile planet: these satellites also track climate, ice, fire, and the health of forests and ocean! More »

Denial of science, science of denial
