Sound thinking


For any wind energy developer, the issue of impacts on local population is one that must not be taken lightly. A new study published via the Commonwealth of Massachusetts has been conducted to look at the potential adverse benefits of wind farm developments on local populations. PES takes a look at the report’s findings…

The Massachusetts Department of Environmental Protection (MassDEP), in collaboration with the Massachusetts Department of Public Health (MDPH), convened a panel of independent experts to identify any documented or potential health impacts or risks that may be associated with exposure to wind turbines, and, specifically, to facilitate discussion of wind turbines and public health based on sound science.

While the Commonwealth of Massachusetts has goals for increasing the use of wind energy from the current 40 MW to 2000 MW by the year 2020, MassDEP recognizes there are questions and concerns arising from harnessing wind energy. Although fossil fuel non-renewable sources have negative environmental and health impacts, it should be noted that the scope of the Panel’s effort was focused on wind turbines and is not meant to be a comparative analysis of the relative merits of wind energy vs. non-renewable fossil fuel sources such as coal, oil, and natural gas. Currently, “regulation” of wind turbines is done at the local level through local boards of health and zoning boards.

Some members of the public have raised concerns that wind turbines may have health impacts related to noise, infrasound, vibrations, or shadow flickering generated by the turbines. The goal of the Panel’s evaluation and report is to provide a review of the science that explores these concerns and provides useful information to MassDEP and MDPH and to local agencies who are often asked to respond to such concerns.

The overall context for this study is that the use of wind turbines results in positive effects on public health and environmental health. For example, wind turbines operating in Massachusetts produce electricity in the amount of approximately 2,100-2,900 MWh annually per rated MW, depending on the design of the turbine and the average wind speed at the installation site. Furthermore, the use of wind turbines for electricity production in the New England electrical grid will result in a significant decrease in the consumption of conventional fuels and a corresponding decrease in the production of CO2 and oxides of nitrogen and sulfur. Reductions in
