Denver to Go 100 Percent Renewable by 2030

Denver became the 73rd city in the U.S. to commit to 100 percent renewable energy when Mayor Michael Hancock announced the goal in his State of the City speech Monday, The Denver Post reported.

The commitment is part of the city's larger 80×50 Climate Action Plan unveiled by Hancock Tuesday, which seeks to reduce Denver's greenhouse gas emissions 80 percent from 2005 levels by the year 2050.

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.

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).

2017 Was a Record Breaking Year for Renewables, But More Needs to Be Done to Meet Paris Goals

2017 broke the record for increased renewable energy capacity, Reuters reported Sunday. But it still isn't enough to reduce carbon dioxide emissions in line with the goals of the Paris agreement.

11 Turbines Successfully Installed at Wind Farm Trump Tried to Block

The world's most powerful wind turbines have been successfully installed at the European Offshore Wind Deployment Centre (EOWDC) off Aberdeen Bay in Scotland's North Sea.

The final turbine was installed on Saturday just nine weeks after the first foundation for the 11-turbine offshore wind farm was deployed, according to the developers Vattenfall.

Scientists Hit Back: Another Paper Claims 100% Renewables is Possible and Affordable

Is it possible for the world to run on 100 percent renewable energy? It's a noble goal, as the best science tells us we must significantly slash fossil fuel consumption or else the planet faces dangerous climate change.

A number of academics believe it's not only feasible to wean off coal, natural gas and other polluting fuels by transitioning to renewable sources such as solar and wind power, it's even cost-effective.
