Policy-makers seeking to limit the impact of coal electricity-generating units (EGUs, also known as power plants) on air quality and climate justify regulations by quantifying the health burden attributable to exposure from these sources. We defined “coal PM2.5” as fine particulate matter associated with coal EGU sulfur dioxide emissions and estimated annual exposure to coal PM2.5 from 480 EGUs in the US. We estimated the number of deaths attributable to coal PM2.5 from 1999 to 2020 using individual-level Medicare death records representing 650 million person-years. Exposure to coal PM2.5 was associated with 2.1 times greater mortality risk than exposure to PM2.5 from all sources. A total of 460,000 deaths were attributable to coal PM2.5, representing 25% of all PM2.5-related Medicare deaths before 2009 and 7% after 2012. Here, we quantify and visualize the contribution of individual EGUs to mortality.
The fate, effects, and treatment of per- and polyfluoroalkyl substances (PFAS), an anthropogenic class of chemicals used in industrial and commercial production, are topics of great interest in recent research and news cycles. This interest stems from the ubiquity of PFAS in the global environment as well as their significant toxicological effects in humans and wildlife. Research on toxicity, sequestration, removal, and degradation of PFAS has grown rapidly, leading to a flood of valuable knowledge that can get swamped out in the perpetual rise in the number of publications. Selected papers from the Journal of Hazardous Materials between January 2018 and May 2022 on the toxicity, sequestration, and degradation of PFAS are reviewed in this article and made available as open-access publications for one year, in order to facilitate the distribution of critical knowledge surrounding PFAS. This review discusses routes of toxicity as observed in mammalian and cellular models, and the observed human health effects i

SACRAMENTO -- Data from the California Energy Commission (CEC) shows that 59 percent of the state’s electricity came from renewable and zero-carbon sources in 2020. The CEC estimates that in 2020, 34.5 percent of the state’s retail electricity sales were served by Renewables Portfolio Standard (RPS)-eligible sources such as solar and wind. When sources of zero-carbon energy such as large hydroelectric generation and nuclear are included, 59 percent of the state’s retail electricity sales came from non-fossil fuel sources in 2020. In 2019, over 60 percent of the state’s electricity came from renewable and zero-carbon sources. The decrease in 2020 is due to decline in hydroelectric generation caused by severe drought, as well as pandemic-related delays to new renewable energy projects.

From the Heart of the World - The Elder Brothers Warning is a documentary about the Kogi people who inhabit the Sierra Nevada de Santa Marta mountain in northern Colombia. Direct descendants of the Tayrona people they survived Spanish Conquistadors - a feat no other tribe can claim. Long thought extinct, they reappeared from their mountain home to warn the world about the harmful damage it was causing.

Later this year, Egyptian engineering firm Arab Contractors is expected to complete the construction of the Julius Nyerere dam on the Rufiji River. Once completed, the $3 billion dam could be Africa’s fourth biggest by power production, producing up to 5920GWH of power annually, enabling Tanzania to close the gap between those with electricity and those who have no access.

The case for cutting meat consumption is so compelling that you would think politicians would be less shy about making it. Yet while campaigners warn with increasing urgency that global livestock production is accelerating climate breakdown and causing devastating damage to nature and human health, governments remain reluctant to tackle meat-eating.
As a leading climate scientist, Paola Arias doesn’t need to look far to see the world changing. Shifting rain patterns threaten water supplies in her home city of Medellín, Colombia, while rising sea levels endanger the country’s coastline. She isn’t confident that international leaders will slow global warming or that her own government can handle the expected fallout, such as mass migrations and civil unrest over rising inequality. With such an uncertain future, she thought hard several years ago about whether to have children.

Rooftop solar panels are up to 79% cheaper than they were in 2010. These plummeting costs have made rooftop solar photovoltaics even more attractive to households and businesses who want to reduce their reliance on electricity grids while reducing their carbon footprints. But are there enough rooftop surfaces for this technology to generate affordable, low-carbon energy for everyone who needs it?
Drawing people into cities could cut emissions and combat housing crises. But even progressives are hard to convince
There are several ways to remove carbon from the atmosphere. One is called bioenergy with carbon capture and storage, or Beccs. Here, vast acres of fast-growing plants are grown and then harvested and burned to generate electricity or make biofuel for vehicles.
