U.S. Wind and Solar Boom Helped Prevent Up to 12,700 Deaths Between 2007-2015

A new study from the Lawrence Berkeley National Lab gives us further reason to transition away from fossil fuels to renewable energy.

According to the research, the U.S. wind and solar power boom helped prevent the premature deaths of thousands of people and saved the country billions of dollars in healthcare and climate-related costs in the years spanning 2007 through 2015.


"We find cumulative wind and solar air-quality benefits of 2015 US $29.7–112.8 billion mostly from 3,000 to 12,700 avoided premature mortalities," according to the paper authored by Dev Millstein of the Lawrence Berkeley National Laboratory in California and his team. The research was sponsored by the Department of Energy and published in the journal Nature Energy.

Unregulated and poorly regulated energy production and use, as well as inefficient fuel combustion, are the "most important man-made sources of key air pollutant emissions," a 2016 International Energy Agency study found. Eighty-five percent of particulate matter—which can contain acids, metals, soil and dust particles, and almost all sulfur oxides and nitrogen oxides can be linked back to those sources.

Unhealthful levels of air pollution can put people at risk for premature death and other serious health effects like lung cancer, asthma attacks, cardiovascular damage, and developmental and reproductive harm. But unlike fossil fuels, wind and solar power systems have no associated air pollution emissions.

As the Independent noted from the current study, major air pollutants have declined between 2007 and 2015. Carbon dioxide fell by 20 percent, sulphur dioxide by 72 percent, nitrogen oxide by 50 percent and tiny particles known as PM2.5 by 46 percent.

This decline is due to fossil fuels being replaced by renewable energy—solar and wind capacity increased from about 10 gigawatts in 2007 to roughly 100GW in 2015—as well as tougher emissions regulations.

The study also estimated that wind and solar contributed to the "cumulative climate benefits of 2015 US $5.3–106.8 billion," which includes "changes to agricultural productivity, energy use, losses from disasters such as floods, human health and general ecosystem services."

"The ranges span results across a suite of air-quality and health impact models and social cost of carbon estimates," the study added. "We find that binding cap-and-trade pollutant markets may reduce these cumulative benefits by up to 16 percent."

Forest Gardening With Space for Wild Elephants

By Michael B. Commons

In my collaboration with Terra Genesis International, I have been given space and support to investigate what we may call "Regenerative Pathways," looking at real life examples of functional farming systems that we can identify as being on the "Regenerative Agriculture Pathway."

While these farms/farming systems might be called "Regenerative Farms," we see regeneration more as a long term process and continuum that we can evaluate through indicators such as soil health, water retention, biodiversity, community health and more.

How Can We Help Put a Human Face on Climate Change?

By John R. Platt

Communicating the truths about climate change isn't always easy. Sometimes the effects of climate change seem to hover in the future, or are occurring most visibly in other parts of the world. Other times they're subtle—at least for now. And of course, there are some people who just don't want to hear anything about it.

Peru's Newest National Park Safeguards 2 Million Acres of Amazon Rainforest

The Peruvian government announced it will establish a new and enormous national park in the Amazon.

Yaguas National Park, located in the northern region of Loreto, consists of 2,147,166 acres of rainforest, a vast river system and is home to more than 3,000 species of plants, 500 species of birds and 160 species of mammals, including giant otters, woolly monkeys, Amazonian river dolphins and manatees. The park also features 550 fish species—one of the richest fish faunas in the world.

Will Cape Town Become the First Major City to Run Out of Water?

Cape Town is on track to become the first major city in the world to run out of water.

The world-renowned tourist destination—and the second-most populous urban area in South Africa after Johannesburg—could approach "Day Zero," when most taps run dry, by April 21, Mayor Patricia de Lille said Tuesday.

Haiti’s Most Popular Ecotourism Destinations

The tropical Caribbean island of Haiti is a paradise with a rich, fascinating history, natural wonders and diverse cultural offerings. It has also been named by some as the next big thing in regional tourism.

But ecotourism in particular could become important for Haiti, with its rich land and sea biodiversity. Globally, the business of ecotourism generates more than $600 billion a year and is connected to hundreds of thousands of jobs.

Nearly All Coastal Governors Denounce Plan to Expand Offshore Oil Drilling

Politicians from coastal states around the country continue to call for their states to be exempt from the Trump administration's proposed expansion of offshore drilling following its politically-tinged decision last week to remove Florida from the plan.

The Interior Department said last week that Secretary Ryan Zinke had spoken with seven coastal governors opposed to drilling, including the governors of North and South Carolina, Rhode Island, Delaware and Washington. Oregon Gov. Kate Brown's office told press Zinke would consider removing the state from the plan following their call, while California Gov. Jerry Brown's office reports that Zinke promised to travel to the state to further discuss the offshore leases.

In Alabama, a Cleanup Unearths Toxins—and Scandal

By Matt Smith

Lot by lot, backhoes and dump trucks are scraping and hauling away yards on the north side of Birmingham to remove soil laced with heavy metals and other industrial wastes—the legacy of this city's years as a steelmaking power.

Federal prosecutors say that effort also uncovered something else: a scheme to save polluters millions by putting the neighborhood's representative in Montgomery on their payroll.

Two Major Food Companies Announce War on Packaging Waste

More and more businesses are stepping up to reduce consumer waste. Iceland Foods, a major UK supermarket chain specializing in frozen food, announced on Tuesday that it will eliminate plastic packaging from its own brand of products by the end of 2023.

In a separate announcement on Tuesday, McDonald's said it will add recycling to its more than 36,000 locations around the world by 2025 and pledges that all packaging on customer products will come from "renewable, recycled or certified sources" by that same year.
