In Bruce Logan’s lab, scientists use sewage to create electricity. And soon wastewater could provide all the power it needs to clean itself up.

Rather than advertising energy-efficiency features, a leading home builder and solar installer are pitching the effect—no electric bill, ever.

What if everyone, not just environmentalists or those who can afford it, could switch to wind- and solar-powered electricity?

These decisions could serve as a national precedent for small groups of people looking to keep big drilling companies at bay.

These companies are working on better batteries, engines that guzzle less gas, and materials to make more fuel-efficient cars.
Let's exert our energy figuring out how to deal with the root problem.

Hospitals use more energy per square foot than almost any other type of building in America. But experts are thinking about how to change that.

The Department of Energy has called cogeneration plants “one of the most promising options in the US energy efficiency portfolio."

Both wind turbines and birds rely on the power of air currents to move them. That means that as more wind turbines are built, the towers claim...

If a community wants to decrease carbon emissions, it needs to tackle emissions created outside its borders to produce the goods it consumes.

Investors haven't abandoned clean tech projects, they're just reevaluating how they fund them.

The budget may not pass through Congress, but it shows Obama's commitment to renewable energy

If delivery fleets went electric, any truck on a city street could provide storage and stability to the grid.

When reporters, politicians, and environmental advocates talk about renewable energy, they talk about wind and solar. This makes sense: Of the...

The Obama administration is speeding up clean energy development, but must balance the interests of conservationists and developers.

“It’s expensive to be poor, and nowhere is that truer than in energy."

As a group, states are already doing more to support clean energy development than the federal government ever dreamed of.
