It's not perfect, but the goal is to move forward and improve things which we can. In FL we have access to EV chargers by the power company that are completely powered by 100% renewable energy sources. This is a powerful network that others would like to strive for, and there is other charging companies out there also working off renewable energy sources for their chargers.
And it's not fully just about the environmental impact of a single car, but in the long run is moving away from fossil fuels and improving our power grids and more green resources, as well as reducing the dependence on oil, especially foreign oil. In turn this also helps reduce the cost and demand of oil/gasoline which in the long run can help many other areas and people. It's going to take time but this is all baby steps that will lead to improvements.
