A new study released this week shows that levels of air pollution that the U.S. Environmental Protection Agency deems safe may not be safe enough. The study, conducted by researchers at the Harvard T.H. Chan School of Public Health, found that long-term exposure to airborne fine particulate matter (PM 2.5) and ozone — even below current standards established by established by the EPA — increases the risk of premature death.
Electric vehicles are increasingly dominating the alternative fuel market for passenger vehicles in the U.S. With this boom in electric vehicle sales, we wondered how other alternative fuel vehicle options fairing. Is there still a place for hybrid, natural gas and hydrogen fuel cell vehicles in the passenger vehicle market?
Yes, you can afford an alt-fuel car.
A new study released this week by Massachusetts Institute of Technology compares the lifecycle cost and emissions of owning 125 different vehicles on the market, and guess what? It turns out that clean cars are a great deal for both the environment and your pocketbook.
Electrifying transportation is one of the most promising ways to significantly cut greenhouse gas emissions from vehicles, but so-called range anxiety – concern about being stranded with an uncharged car battery – remains a barrier to electric vehicle adoption. Is range anxiety justified given current cars and charging infrastructure?
It’s a question my research group and I addressed in a recent study. Specifically, we asked: When looking down on the geographic area of the U.S. from a bird’s-eye view, how many personal vehicles on the road daily could be replaced with a low-cost battery electric vehicle (EV), even if daytime charging isn’t available?
In case you missed any, here’s a roundup of our most popular blog posts of 2015. As you can see by this list, our readers are more interested than ever in learning about the food waste problem and finding ways to fix it. On the fuel side, stories about innovation and idling reduction were popular, too.
Some studies have found that replacing gasoline vehicles with electric vehicles is like trading one dirty fossil fuel for another if the electricity is coming from a coal-fired power plant. Other studies make a good case for driving electric even in regions dominated by coal.
These studies are helpful if you’re evaluating which car to buy and drive today, but what about in the future? What impact can getting more EVs on the road have as the energy grid gets cleaner? Can EVs make a significant difference in lowering total emissions?
The electric vehicle is one of the most promising sustainable methods of personal transportation. But what about the batteries used to power EVs? Once they can no longer power a car, it is important that EV batteries are not simply thrown into landfills, but rather recycled or better yet, repurposed.
We often blog about how businesses with vehicle fleets can be more fuel-efficient. But what about our nation’s largest fleet: school buses. Tasked with carrying 25 million children to school every day, our collective school bus fleet is the largest form of mass transit in the United States. Making the 480,000 buses in operation more fuel-efficient would go a long way to reducing oil usage in our country.
As a Washington, DC, native, I thought I understood traffic well, but I didn’t truly know how bad it could be until I moved to Connecticut. I drive a Ford C-Max Energi to work, and this 16-mile drive can easily take an hour door-to-door, and that’s all highway miles.
