Renewable Energy

More than a third of the credits issued under a tax credit program for renewable energy companies in Oregon went to problematic projects. That's according to an independent analysis issued Thursday by the Oregon Secretary of State's office.

San Francisco will soon begin requiring new buildings to have solar panels installed on the roof.

It's the first major U.S. city to have such a requirement, according to Scott Weiner, the city supervisor who introduced the bill.

Americans throw away about a third of our available food.

But what some see as trash, others are seeing as a business opportunity. A new facility known as the Heartland Biogas Project is taking wasted food from Colorado's most populous areas and turning it into electricity. Through a technology known as anaerobic digestion, spoiled milk, old pet food and vats of grease combine with helpful bacteria in massive tanks to generate gas.

Renewable energy like solar and wind is booming across the country as the costs of production have come down. But the sun doesn't always shine, and the wind doesn't blow when we need it to.

This challenge has sparked a technology race to store energy — one that goes beyond your typical battery.

Heat Storage: Molten Salt And A Giant Solar Farm

Batteries are often used to store solar power, but it can be a costly endeavor.

Oregon's biggest power companies will have 14 years to wean themselves from coal, under a new bill approved by lawmakers Wednesday. The measure has the support of Gov. Kate Brown — and the state's two largest electric companies.

Several environmental groups have backed the bill, which calls for requiring large utilities to ensure that at least 50 percent of their power comes from renewable sources by 2040.

As the biodiesel industry convenes for a national conference in San Diego today, one of the topics of discussions will be the loosening of the renewable fuel standard.

Among the participants will be Seattle-based General Biodiesel, a company that turns used cooking oil into vehicle-grade fuel. The company 's CEO is upset over backpedaling by the federal government on incentives for more use of alternatives.

Natural gas from organic waste is gaining momentum as a renewable energy source, and a local transit agency is already on board. 

You could call it power that’s growing on trees, but doesn’t get put to good use.

The US Forest service recently announced $4-million in grants to support projects that convert wood to energy. It's part of a program that's meant to support small businesses that create jobs while encouraging alternatives to fossil fuels.

The same forces of nature that create natural hot springs and volcanoes may soon become a source of electricity in Snohomish County. The county’s Public Utility District has broken ground on a deep geothermic well, just north of the town of Skykomish.

The exploratory well is the first of its kind in Washington.

As interest in solar power gains momentum, Seattle City Light is marketing a new program to make it more widely available. 

Community Solar gives people who can’t install solar panels on their own homes the chance to reap the rewards of a cash investment in solar power.

From carousels to picnic shelters and libraries, solar power is becoming more commonplace in Seattle.

City Light says it has seen big growth in customer demand for alternative energy over the past decade – and small solar is one of the biggest draws.

The amount of wind power in the Northwest is likely to double – and perhaps triple– over the next 15 years. That's according to a new estimate delivered Tuesday.

An effort in Olympia to broaden Washington’s renewable energy law is running into opposition.

Green energy groups say the proposed change would weaken the voter-approved Initiative 937.

An Oregon-based alternative energy company is one step closer to generating electricity from the ocean's waves. The company has launched a prototype wave energy buoy. For testing, the startup chose the gentler waters of Puget Sound.

Ideas for harnessing the power of the Pacific Ocean to create clean energy are proliferating.  The rush of creativity is creating a flood of visits by electric engineers to coastal communities.
