Two case studies outline how Houston and Loveland are saving money with EVs in their fleets

Green Car Congress

City officials in Houston estimate that the city’s 27 Nissan LEAF electric vehicles will save the city $110,000 annually compared to internal combustion engine vehicles. We project that electric vehicles will save the city $110,000 per year in reduced fuel and maintenance, costs that we would otherwise have to spend on gas-powered vehicles.

The Case for Nuclear Cargo Ships

Cars That Think

Shipping uses over 300 million tonnes of fossil fuels every year, producing 3 percent of greenhouse gas emissions. At a July meeting of the International Maritime Organization , the U.N. The IMO’s previous goal was a 50 percent reduction by 2050 in comparison with 2008 levels. One is a thorium-fueled molten-salt reactor.

Study suggests high-mileage light-duty fleets contribute higher emissions and emissions share than expected

Green Car Congress

High emitters occur as a result of breakage, mal-maintenance (performance modifications, rechipping, and/or after-treatment removal), and at end of a vehicle’s useful life. Livery fleets have changed significantly in the past decade, with many city fleets now featuring large numbers of hybrid and alternatively fueled vehicles.
