Chicago Takes Giant Step Towards Becoming 100% Renewable

By Alexander Laska

The city of Chicago announced this week that renewable energy will power 100 percent of all of its government buildings by 2025, making the Windy City the country's largest to make that pledge.


That's no small feat: With more than 900 city-owned buildings—including public schools and colleges, park district fieldhouses and buildings owned by the Chicago Housing Authority—Chicago has the country's largest fleet of public buildings. Last year, they accounted for eight percent of all electricity use in Chicago.

Chicago Mayor Rahm Emanuel said the city will meet its goal by acquiring renewable energy credits, purchasing utility-supplied renewable energy through the state's renewable portfolio standard and increasing on-site generation by installing more wind turbines and solar panels.

If going 100 percent is a challenge, wind is up to the task: It already supplies 5.7 percent of Illinois's electricity needs. That's enough to power more than 982,000 homes and Illinois ranks as the seventh highest state in installed wind generating capacity.

"By committing the energy used to power our public buildings to wind and solar energy, we are sending a clear signal that we remain committed to building a 21st-century economy here in Chicago," Emanuel said.

Illinois already reaps the economic benefits of wind: The industry employs more than 4,000 people in the state, gives over $10 million annually in land-lease payments to farmers and ranchers hosting turbines and has brought $8.4 billion in investment into Illinois's economy.

Across the U.S., there is a clear trend of cities large and small committing to go big on clean energy and using wind power to get there: Greensburg, Kansas gets 100 percent of its electricity from wind and Georgetown, Texas became 100 percent renewable earlier this year, using 50 percent wind energy.

By committing to powering all of its public buildings with clean energy, Chicago has become America's next and biggest city to take a giant step towards becoming 100 percent renewable.

The Big Apple Loses to Big Oil as Judge Dismisses Climate Liability Suit

A federal judge ruled on Thursday in favor of a motion by five big oil companies to dismiss a lawsuit brought against them by New York City, which demanded they pay the costs of adapting the city's infrastructure to climate change, The New York Times reported.

The ruling comes nearly a month after a federal judge in San Francisco dismissed a similar case brought by the cities of Oakland and San Francisco.

New Dicamba Drift Estimate: 1.1 Million Acres Damaged Already in 2018

A University of Missouri report released Thursday estimates that drift damage from the pesticide dicamba has occurred across 1.1 million acres of agricultural crops, trees and other plants so far this year.

This comes less than a year after the U.S. Environmental Protection Agency (EPA) and many states introduced additional restrictions meant to prevent off-target damage from the pesticide. Last year dicamba drift wreaked havoc on a reported 3.6 million acres of soybean crops not genetically engineered to resist the notoriously drift-prone pesticide.

Most Popular Energy Source? Everyone Loves Solar

By John Rogers

A recent survey shows yet again that solar panels (and wind turbines) have a level of bipartisan popularity that would be the envy of any politician. That means we'll have something safe to talk about at the next barbecue after all.

‘Powerful Evidence’ of Global Warming’s Effect on Seasons Found in Troposphere

By Daisy Dunne

Scientists studying the troposphere—the lowest level of the atmosphere—have found "powerful evidence" that climate change is altering seasonal temperatures.

A study published in Science finds that climate change has caused an increase in the difference between summer and winter temperatures across North America and Eurasia over the past four decades.

Against All Odds, Mountain Gorilla Numbers Are on the Rise

By Jason Bittel

The news coming out of East Africa's Virunga Mountains these days would have made the late (and legendary) conservationist Dian Fossey very happy. According to the most recent census, the mountain gorillas introduced to the world in Gorillas in the Mist, Fossey's book and the film about her work, have grown their ranks from 480 animals in 2010 to 604 as of June 2016. Add another couple hundred apes living in scattered habitats to the south, and their population as a whole totals more than 1,000. Believe it or not, this makes the mountain gorilla subspecies the only great apes known to be increasing in number.

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.
