The Houston Chronicle recently reported on the benefits electric cars can provide to cities as they combat climate change.
“We studied vehicle options available to Houston, which operates a fleet of about 12,000 vehicles, in 2015. Those options included two gasoline-powered Toyota sedans (the Corolla and the Prius), the natural gas-powered Honda Civic, the plug-in hybrid Toyota Prius and the fully electric Nissan Leaf. Since all these sedans seat five passengers, they are interchangeable.
Because Houston in 2015 bought 75 percent of its electricity from wind farms (it now draws even more of its power from wind and solar sources), we calculated that the fully electric Leaf would have reduced life cycle greenhouse gas emissions by 87 percent relative to the gasoline-powered Corolla over seven years. About half of those benefits would have been lost if the Leaf was charged from the fossil-heavy grid elsewhere in Texas.
Financially, the savings on fuel and maintenance would have more than offset the $12,000 premium for buying a Leaf instead of a Corolla. We estimated that Houston would have saved about $.0.04 per mile while operating the Leafs, as long as enough charging stations were available. That’s even before counting any savings from bulk purchases or federal tax credits.”
