What scientists know well, and what's left to learn, about extreme weather and climate change.
Transportation accounts for 28 percent of Americans’ overall greenhouse gas emissions. Here's a look at how various modes stack up.
A graphic comparing the output of small modular reactors to conventional nuclear power reactors.
For decades, some nuclear engineers have been pushing an alternate technology that they claim could address all the concerns of conventional nuclear reactors. Called Small Modular Reactors (SMRs), these plants,would be inherently cheaper to build and safer to operate than conventional plants.
Renewable Fuel Standards designate the minimum levels at which several categories of biofuel are consumed through 2022.
CO2 emissions from fossil fuel have been growing steadily in the US and are projected to continue growing until 2030 and beyond if no legislation is passed to reduce emissions.
