Considering All the Benefits of Residential Renewable Energy is Critical
I wrote this article for the Huffington Post. It can be found in its original context here.
Ask most people about the benefits of residential renewable energy—geothermal, rooftop solar photovoltaic and solar thermal, and backyard wind turbines, primarily–and the response is usually the same: they are good for the environment, raise property value and lower or eliminate utility bills. While undoubtedly true, these responses present an incomplete picture of the benefits of distributed renewable energy. In certain instances, such as last week when a single ice storm left over 1 million homes and businesses in New England without power, a residential energy system can mean the difference between seeking shelter and being able to shelter others. Other times, particularly during peak demand, renewables stabilize the grid and lower costs for all utility customers.
The Grid Can Fail, and It’s Expensive When It Does
America’s electricity grid is an engineering marvel, but it is also old, outdated, overstrained and susceptible to failure from storms, terrorism, accidents and high energy demand. And when the grid fails, not only is the loss of power inconvenient, it is also dangerous and costly. For example, the 2003 blackout that stretched from Canada to New York was estimated to have an economic cost of “between $7 and $10 billion. . .due to food spoilage, lost production and overtime wages” as well as the cost of repairing and upgrading the affected parts of the grid. While the 2003 grid failure was one of the most extraordinary outages to hit the United States, smaller scale blackouts, particularly from storms and natural disasters, are rather common.
