A study conducted in the US has come to conclusions which do not sit well with EV ownership depending on the source of energy. If an electric vehicle is powered via a coal powered power station the pollution results are worse than for a gasoline powered vehicle and cause 86% more deaths due to air pollution. “If it comes from coal, the electric cars produce 3.6 times more soot and smog deaths than gas, because of the pollution made in generating the electricity, according to the study that is published Monday by the Proceedings of the National Academy of Sciences.”
This is quite damming news for anyone powering their EV from a coal fired power plant – they are doing more harm than good. The ideal solution is powering from renewable energies if possible. The study also found that electric vehicles powered by natural gas power plants produce just half the air pollution health problems compared to gasoline powered vehicles. Read more here
For those in Australia and sunnier climates roof top solar is the perfect solution. With battery prices set to fall dramatically over the next couple of years due to the likes of Elon Musk’s Gigafactory, battery storage, vehicle to home connectivity and smart control systems will mean clean fuel and power.
