Solar Arrays Are A Health Threat, Because Electromagnetic Fields, Or Toxic Runoff Or . . Something [View all]

EDIT

Still, a state board in Ohio rejected an application for a solar project last month, citing local opposition, even though its staff initially said it met all requirements. Along with other concerns, according to the board, opponents “testified about the potential impacts on the health of residents.” A bill in Missouri would halt commercial solar projects in the state, including those under construction, through at least 2027, as a state agency develops new regulations. The bill’s emergency clause says this is “deemed necessary for the immediate preservation of the public health, welfare, peace, and safety.”

And, on the eastern edge of Michigan, St. Clair County adopted a novel public health regulation last year that set limits on solar development and battery storage. The move was encouraged by the county’s medical director who, in a memo, warned of the threat of noise, visual pollution and potential sources of contamination. Some local residents have long pressed leaders to act, saying that intrusive noise could worsen post-traumatic stress disorder and other ailments. Public officials don’t always examine the validity of health claims, according to Rule. And local deliberations rarely compare the impact of solar farms to common agricultural practices, which can lead to runoff from fertilizers and herbicides, for example, or waste lagoons from concentrated animal feeding operations.

While the future farmability of the land is often a concern, many researchers — and farmers — say that a solar lease will help preserve it.With proper planning on the front end, equipment can be removed from a decommissioned solar site and green space restored, said Steve Kalland, executive director of the NC Clean Energy Technology Center, which, along with its partners, provides technical assistance to local governments in the Carolinas. And a person’s exposure to the electromagnetic field, or EMF, from a solar farm is roughly the same as what they would encounter from ordinary household appliances, according to researchers. EMF levels also decrease rapidly with distance.

Chronic exposure to noise is also a recurring complaint from critics. In challenging a proposed project from Adair’s company in Morrow County, Ohio, one woman said in a brief to the state siting board that she was troubled about how noise from the facility might affect people with neurological noise sensitivities, including her daughter. A piece of equipment called an inverter is usually the source of noise on a solar site. It converts the current into the form that’s used on the grid. But noise, as well as glare, are typically buffered with vegetative landscaping and setbacks, or the distance between the property line and the nearest structure. Inverters can also be placed far from the ears of neighbors.
