Today’s mass-market battery electric vehicles are also a good deal and will likely save money for consumers compared to similar gasoline-powered vehicles. Battery-powered EVs cost less to own than comparable gasoline-powered vehicles once the full life-cycle costs of car ownership and federal and state incentives for EV purchases are accounted for.
America has made progress in cutting pollution from cars and trucks over the last decade as a result of improved vehicle fuel economy and slower growth in driving. But eliminating greenhouse gas emissions from our urban transportation systems is going to require more than incremental change – it will require transformation.
America’s major cities have played a key role in the clean energy revolution and stand to reap tremendous benefits from solar energy. As population centers, they are major sources of electricity demand, and with millions of rooftops suitable for solar panels, they have the potential to be major sources of clean energy as well.
The rooftops of America’s big box stores and shopping centers could host 62.3 gigawatts (GW) of solar photovoltaic capacity, equivalent to the amount of electricity used by more than 7 million average U.S. homes or more than 7,500 average Walmart stores, and more than triple the solar photovoltaic capacity that has been installed in the U.S. to date.
