Did you know that pairing an electric vehicle with rooftop solar can drastically reduce your carbon footprint and save money at the same time!
That's right, you can power your electric car with sunshine. When you pair an electric car with solar energy you are not only eliminating local pollution from tailpipe emissions, you are driving on clean, renewable energy! By combining an electric car with rooftop solar energy you can breathe easy knowing you are driving carbon-free. The savings from powering your car with rooftop solar rather than gasoline can really add up. Rooftop solar allows you to lock in your energy costs and hedge against rising fuel prices, saving you money on your utility bill.
Poor air quality is the result of the unique geography of the Wasatch Front coupled with pollution generated from transportation, industry, and buildings. "Mobile sources" of air pollution (like vehicles) are a major contributor to a certain type of pollution known as particulate pollution, or "PM 2.5", emitting 48% of Utah’s criteria air pollutants (the most harmful types of air pollution). By transitioning our traditional polluting vehicles to cleaner, electric vehicles and plug-in hybrid cars, we can tackle a big part of Utah’s air quality problem. According to the Department of Energy EVs convert up to 80% of the energy stored in their batteries to power the vehicle. Compare that to the 14 – 26% of the energy stored in gasoline being converted to power an internal combustion vehicle. According to a 2013 analysis conducted by SWEEP and Utah Clean Energy "all electric" vehicles produce 99% lower emissions of volatile organic compounds (VOCs), 95% less sulfur dioxide (SO2) emissions, 76% less nitrogen oxides (NOx) emissions as compared to a new gasoline vehicle. Plug-in hybrid electric vehicles reduces emissions significantly as well.
In addition to air quality benefits are the greenhouse gas emissions reductions from EVs. A recent report from the Union of Concerned Scientists finds that the life cycle greenhouse gas emissions from EVs are at least 50% less than comparable gasoline vehicles. The emissions associated with manufacturing EVs are slightly higher than gasoline vehicles, but once in operation EVs contribute significantly less emissions. The reduction in emissions from operating an EV can make up for the emissions from manufacturing it in as little as one year. After its useful life the battery can be reused or recycled, further reducing the climate impacts of EVs when compared to gasoline vehicles. You can read the full report here, and you can compare EV emission with gasoline vehicle emissions with this calculator from the Union of Concerned Scientists.
