The Centre Daily Times reports on geologist Richard Alley, a Penn State professor who explored possible solutions to climate change for a special on PBS.
He goes bungee jumping down a glacial crevasse, gets close with a herd of cows in Pennsylvania and explores what he calls a "glorious" cave in New Zealand that’s home to glowworms. The energy efficient creatures make light to lure in their prey. Alley also tours places like a desert in the southwest United States where solar panels could create sustainable energy.
"The amount of energy that's available is absolutely incredible," Alley said. "It's all there. The question is how to use it."
To explore that, Alley and the film crew visit places already producing green energy, such as a solar power plant near Seville, Spain, and a geothermal generating station in New Zealand.
