Third U.S. City Goes 100% Renewable

Aspen is one of three U.S. cities to run on 100 percent renewable energy as of today, according to city officials. The Colorado mountain town is best known for its posh ski resorts, but this beautiful town also has established itself as a leader in environmental stewardship.

The city had been using about 75 to 80 percent renewable energy until Thursday when it signed a contract with wholesale electric energy provider Municipal Energy Agency of Nebraska, in order “to achieve this final leg of our goal,” David Hornbacher, utilities and environmental initiatives director, told The Aspen Times.

The goal was proposed 10 years ago as part of the city's Canary Initiative, which "identifies Aspen and other mountain communities as canaries in the coal mine with respect to their sensitivity to the effects of climate change."

The city's "100 percent" goal is just one component of its larger strategy to reduce both operational and community-wide greenhouse gas emissions 30 percent below 2004 levels by 2020 and 80 percent below 2004 levels by 2050, said Chris Menges and Will Dolan from Aspen's sustainability and utility departments. As of February, the city has reduced its operational emissions by 42 percent, while (as of July) community-wide emissions have been reduced by 7 percent (from 2004 levels).

“It was a very forward-thinking goal and truly remarkable achievement,” Hornbacher said. “This means we are powered by the forces of nature, predominately water and wind with a touch of solar and landfill gas.”

“We’ve demonstrated that it is possible” and that a small, progressive community can work together to be a pathway for others, he said. “Realistically, we hope we can inspire others to achieve these higher goals.” The first two U.S. cities to reach the goal were Burlington, Vermont and Greensburg, Kansas, which decided to make the move after it was devastated by a powerful tornado in 2007.

Aspen plans to celebrate with an "electric-pride party" and also wants to "launch a big national campaign" to show other cities that running a city on 100 percent renewable energy is possible.

Despite Trump’s Bluster, U.S. Officials and Scientists Maintain Climate Work with International Partners

Trump has loudly declared his intention to withdraw the U.S. from the Paris agreement, but, behind the tweets and the headlines, U.S. officials and scientists have carried on working with international partners to fight climate change, Reuters reported Wednesday.

EPA Sued Over Failure to Release Correspondence With Heartland Institute

The U.S. Environmental Protection Agency (EPA) is being sued for its "unlawful and unreasonable delay" in responding to requests for information about the agency's communications with the Heartland Institute, according to a complaint by the Southern Environmental Law Center (SELC) and the Environmental Defense Fund (EDF).

The Heartland Institute is an Illinois-based think tank that rejects the science of man-made climate change and has received funding from the Koch brothers and the fossil fuel industry.

Trump Administration Seeks to Gut Water Pollution Safeguards, Putting Communities at Risk

By Mary Anne Hitt

A Hollywood scriptwriter couldn't make this up. One day after new data revealed widespread toxic water contamination near coal ash disposal sites, U.S. Environmental Protection Agency (EPA) head Scott Pruitt announced a proposal to repeal the very 2015 EPA safeguards that had required this data to be tracked and released in the first place. Clean water is a basic human right that should never be treated as collateral damage on a corporate balance sheet, but that is exactly what is happening.

Why Trump’s New Trophy Hunting Council Is a Disaster

By Elly Pepper

In early November—the same week the Trump administration announced its disastrous decision to allow elephant and lion trophy imports from Zimbabwe and Zambia—the administration decided to create an advisory committee, the International Wildlife Conservation Council (IWCC), to advise Trump on how to enhance trophy hunters' ability to hunt internationally.

Yup, that means the administration now has a council dedicated exclusively to promoting the killing of more imperiled species, like elephants and lions, for sport. The council's mandate includes counseling Trump on the economic, conservation, and anti-poaching benefits of trophy hunting, of which there are very few. Sadly, Trump doesn't want advice on the many drawbacks of trophy hunting.

Walmart Files Patent for Robot Bees

With the mass die-off of bees spelling trouble for agriculture, the world's largest retailer has filed patents for the use of "unmanned vehicles," or drones, to aid with pollination and crop production.

In U.S. Patent Office documents made public last week, Walmart has applied for six patents on drones designed to identify pest damage, spray pesticides and pollinate plants.

Climate Change Threatens Easter Island

Easter Island has long served as a reminder of what happens to a civilization when the environment it depends upon collapses. Now, the iconic remains of that civilization are under threat from a new environmental challenge: global climate change.

Easter Island, Rapa Nui in Polynesian, is surrounded by statues called moai situated on top of ahu, or platforms. But according to an in-depth report for The New York Times published Thursday, the moai are now at risk from erosion caused by sea level rise.

'Climate Change' Removed From FEMA's Strategic Plan

Last year, one of the hottest years in modern history, was also the costliest year ever for weather disasters, setting the U.S. back a record-setting $306 billion in spending aid and relief cost.

But it appears the Federal Emergency Management Agency (FEMA), the agency that responds to hurricanes, flooding and wildfires, is ignoring a critical factor that exacerbates these natural disasters: climate change.
