Public Health Benefits of Adding Offshore Wind to the Grid
By Jonathan Buonocore
New plans to build two commercial offshore wind farms near the Massachusetts and Rhode Island coasts have sparked a lot of discussion about the vast potential of this previously untapped source of electricity.
But as an environmental health and climate researcher, I'm intrigued by how this gust of offshore wind power may improve public health. Replacing fossil fuels with wind and solar energy, research shows, can reduce risks of asthma, hospitalizations and heart attacks. In turn, that can save lives.
So my colleagues and I calculated the health impact of generating electricity through offshore wind turbines—which until now the U.S. has barely begun to do.
Greening the Grid
New England gets almost none of its electricity from burning coal and more than three-quarters of it from burning natural gas and operating nuclear reactors. The rest is from hydropower and from renewable energy, including wind and solar power and the burning of wood and refuse.
The health benefits of moving to wind power would be significant, particularly for regions that rely more heavily on coal and oil to generate electricity.
Replacing coal and oil with offshore wind will reduce emissions of air pollutants like fine particulate matter, nitrogen oxide and sulfur dioxide. These pollutants can form smog, soot and ozone. When people downwind are exposed to them, they can develop incapacitating and deadly diseases.
Saving 13 Lives a Year
When my colleagues and I studied what would happen if offshore wind farms were installed off the Mid-Atlantic coast, we determined that they would bring about health and climate benefits.
We projected that a 1,100-megawatt wind farm off the coast of New Jersey, a bit smaller than the two approved offshore wind farms, would save around 13 lives per year.
When connected to the grid, this new source of power would make carbon emissions decline by around 2.2 million tons every year, the equivalent to taking more than 400,000 cars off the road.
Offshore wind faces a number of technical and economic hurdles, including installation of transmission lines. But at least theoretically, this form of renewable energy could generate enough electricity to supply all the electricity the U.S. consumes and then some, according to the Energy Department. Members of the Trump administration, including Interior Secretary Ryan Zinke, appear to support offshore wind.
While it may not be possible, practical or necessary to build offshore wind everywhere, even replacing a small portion of the nation's fossil-fueled electricity will be good for everyone's health.

It's that time of year again: Right now, monarch butterflies are taking wing in the mountains of northwestern Mexico and starting to flap their way across the United States.
At EcoWatch, our team knows that changing personal habits and taking actions that contribute to a better planet is an ongoing journey. Earth Day, happening on April 22, is a great reminder for all of us to learn more about the environmental costs of our behaviors like food waste or fast fashion.
To offer readers some inspiration this Earth Day, our team rounded up their top picks for films to watch. So, sit back and take in one of these documentary films this Earth Day. Maybe it will spark a small change you can make in your own life.

Guinness is joining the fight against single use plastic. The brewer has seen enough hapless turtles and marine life suffering from the scourge of plastic.
People of all ages are spending more of their day looking at their phones, computers and television screens, but parents now have another reason for limiting how much screen time their children get — it could lead to behavioral problems.
