NEXT100 provides an in-depth look at the intersection of the clean energy business and the environment. It focuses on trends in green technology, policy and the Earth’s climate that will most impact the energy industry and our customers over the next 100 years–PG&E’s second century in operation.

NEXT100 is written and edited by Jonathan Marshall, with contributions from colleagues at PG&E. Postings on NEXT100 represent the opinions of the authors and do not necessarily reflect the official position of PG&E.

Small Hydro, Big Potential

It’s called “small hydro,” but U.S. Department of Energy and industry experts say there’s big potential to create more renewable energy from hydroelectric projects of 30 megawatts or less.

Earth vs. Sun: House Acts to Prevent Grid Meltdown

In old science fiction plots, it took an extraterrestrial threat—usually aliens in space ships—to unite the quarreling peoples of Earth and make them appreciate the virtues of cooperation.

Range Anxiety: An Update from Nissan

Last week, in a NEXT100 feature on electric vehicles and “range anxiety,” I noted lingering uncertainty over the claimed 100-mile range of the much-anticipated Nissan LEAF all-electric five-passenger car.

Climate Changes

Senate Republicans failed to block a plan that would allow the Environmental Protection Agency (EPA) to impose new global warming regulations aimed at reducing carbon dioxide emissions.

Coming Soon: The Solar Demonstration Zone Project

One of the most promising sources of clean, renewable energy in California and the Southwest is concentrating solar power (CSP). This thermal technology typically uses mirrors to concentrate the sun’s energy to create intense heat, which in turn can be used to run a steam turbine or heat engine to generate hundreds of megawatts of electricity.

"PG&E" refers to Pacific Gas and Electric Company, a subsidiary of PG&E Corporation.
