Atlanta Charts Difficult Path to 100 Percent Clean Energy

By Jeremy Deaton

At the start of 2017, just 22 cities had committed to sourcing all of their power from clean energy by 2050. As of this week, that number is 72. Since President Trump moved into the Oval Office and started ripping up federal climate policy, dozens of cities in conservative states have set ambitious goals for clean power, including Salt Lake City, St. Louis and Atlanta. Now for the hard part. These cities must chart a course to reaching their goal.

A Coder and a YouTuber Provide DIY Power for Puerto Rico

By Tom Cassauwers

Before the hurricane came, I was a software engineer. I'd graduated with a bachelor's degree in graphic design and animation, but here in Puerto Rico there weren't many jobs in that field, so I taught myself how to code. When I began, I didn't even know how to make "hello world" appear. After a while, I was building full-blown apps.

World's First Offshore Wind Battery Installed at Floating Farm

A revolutionary battery has been successfully installed at the Hywind Scotland, the world's first floating offshore wind farm located about 15 miles off the Aberdeenshire coast.

With the 1.2-megawatt storage system known as "Batwind" in operation, it will be possible for the first time to store energy produced from an offshore wind farm, developers Masdar and Equinor touted in a press release Wednesday.

Public Health Benefits of Adding Offshore Wind to the Grid

By Jonathan Buonocore

New plans to build two commercial offshore wind farms near the Massachusetts and Rhode Island coasts have sparked a lot of discussion about the vast potential of this previously untapped source of electricity.

But as an environmental health and climate researcher, I'm intrigued by how this gust of offshore wind power may improve public health. Replacing fossil fuels with wind and solar energy, research shows, can reduce risks of asthma, hospitalizations and heart attacks. In turn, that can save lives.

U.S. Sees Steady Solar Growth Despite Trump, But China Slashes Subsidies

By Andy Rowell

Donald Trump can't stop the sun from shining. Despite the climate denier's pro-fossil fuel agenda, and despite his tariffs on imported solar panels, the U.S. still installed more solar than any other source of energy in the first quarter of the year.

The amount of solar power installed in the U.S. climbed 13 percent in the first quarter, according to the trade body, the Solar Energy Industries Association (SEIA).

Samsung Commits to 100 Percent Renewable Energy by 2020

Samsung Electronics announced Thursday an aim to source 100 percent renewable energy for its energy used in all of its factories, office buildings and operational facilities in the U.S., Europe and China by 2020.

Specific locations were chosen as they are "well-equipped with infrastructure for the development and transmission of renewable energy," the South Korean tech giant said on its website. Samsung has 17 of its 38 global manufacturing factories, offices and buildings in those markets.

Major Coal-Fired Power Plant in Washington to Go Solar

By Starre Vartan

It was once Washington state's largest coal pit, a terraced, open-to-the-sky strip mine, five miles from the city of Centralia and halfway between Seattle and Portland, Oregon. Today, the coal beds are quiet and blanketed in green, but an adjacent TransAlta power plant with three tall stacks still churns out electricity the traditional way, with coal now supplied from Wyoming.
