In a Stunning Turnaround, Britain Moves to End the Burning of Coal
September 18, 2017 09:02 AM - Yale Environment 360

Bigger than any medieval castle, with its 12 giant white cooling towers gleaming in the sun, the Drax Power Station dominates the horizon for tens of miles across the flat lands of eastern England. For four decades, it has been one of the world’s largest coal power plants, often generating a tenth of the U.K.’s electricity. It has been the lodestar for the final phase of Britain’s 250-year-long love affair with coal – the fuel that built the country’s empire and industrialized the world.

Stanford researchers team up to reduce pollution and improve health
September 15, 2017 02:40 PM - Stanford University

Stephen Luby’s epiphany came to him 30,000 feet up in the air. The Stanford epidemiologist was flying over India when he realized the view from his window seat was adequate to identify brick kilns on the ground below. The insight was startling for its potential to shed light on an environmental nightmare that kills thousands of people every year.

People of color still exposed to more air pollution
September 15, 2017 12:26 PM -

Pollution exposure for minority groups is still a big problem, according to a new nationwide study conducted by a team of researchers led by CEE professor Julian Marshall

The study found that during a 10-year period, little progress was made in reducing disparities between whites and people of color when it comes to being exposed to harmful air pollution emitted by vehicles. The study focused specifically on outdoor concentrations of nitrogen dioxide, which is a transportation-related pollutant.

New Orleans Greenery Post-Katrina Reflects Social Demographics More Than Storm Impact
September 15, 2017 11:25 AM - Ecological Society of America

Popular portrayals of “nature reclaiming civilization” in flood-damaged New Orleans, Louisianna, neighborhoods romanticize an urban ecology shaped by policy-driven socioecological disparities in redevelopment investment, ecologists argue in a new paper in the Ecological Society of America’s open access journal Ecosphere.

Using ethanol instead of gasoline as a car fuel can reduce emissions of ultrafine particles by a third, which benefits human health and the environment, according to a new study.

 

Cost of U.S. Solar Drops 75 percent in Six Years, Ahead of Federal Goal
September 13, 2017 04:41 PM - Yale Environment 360

The Trump administration has announced that a federal goal to slash the cost of utility-scale solar energy to 6 cents per kilowatt-hour by 2020 has been met early. The goal, set by the Obama administration in 2011 and known as the SunShot Initiative, represents a 75 percent reduction in the cost of U.S. solar in just six years. It makes solar energy-cost competitive with electricity generated by fossil fuels.

Wax On, Melt Off

Drexel University researchers have made a discovery that could create roads that melt off ice and snow during winter storms. Their secret? — Adding a little paraffin wax to the road’s concrete mix.

Low-Level Radiation Less Harmful to Health Than Other Lifestyle Risks
September 13, 2017 11:02 AM - University of Oxford

Human populations have always been exposed to ionizing radiation, and more so in modern life due to its use in medicine, industry and the armed forces. Whilst the risks to human health from medium and high-level radiation are relatively well-understood, the risks at lower levels are less clear.  Mixed messages about the safety of low doses of radiation from different sources have created confusion for the public and for policy makers.
