California is pushing back. Because the state had terrible smog conditions in the past, the Clean Air Act allowed California to set stricter vehicle emissions standards than the EPA and let other states follow those standards. On May 1, California and 16 other states plus the District of Columbia sued the Trump Administration about the proposed weakening of fuel economy standards.
In any case, Steve Cohen, executive director of the Earth Institute, is not worried that the proposed rollback will harm the U. Both things are hard to do. The EPA will work with the Department of Transportation to propose new standards for to cars, no doubt weakening the current standards.
The revised standards will then be open to public comment and will probably face legal battles. In recent years, low oil prices have encouraged Americans to drive more miles and buy more SUVs and pickup trucks, which now make up 60 percent of the U.
While consumers may respond to short-term cheap fuel prices by buying fossil-fuel cars, EVs have long-term benefits and are improving all the time. To find out how electric vehicles and fossil fuel cars stack up, the management consultancy Arthur D. It looked at all stages of their lives from research and development, to sourcing of raw materials and manufacturing, through ownership and disposal. The study found that, mile for mile, EVs cost less to drive than gasoline-powered cars and cost less to maintain.
The total cost of ownership for EVs, however, is higher because they are more expensive to produce, mainly due to the cost of manufacturing their batteries. A Union of Concerned Scientists life cycle analysis found that EVs require more minerals and energy to build than fossil fuel cars, and thus produce more global warming emissions.

But because they do not burn gasoline, EVs offset these higher emissions relatively quickly, and emit less throughout their whole lives. Over their lifetimes, EVs produce half as much global warming emissions as comparable gasoline-powered cars.
The Little report determined, however, that EVs result in three times more toxicity, mainly due to the heavy metals, such as cobalt, used in manufacturing the batteries. These metals can shorten the lives of those working in and around polluting mines in the Congo and China, for example. Cohen maintains that the situation will improve.

Looking ahead to , the Little analysis predicted that while the difference in the total cost of ownership will narrow, gasoline powered cars will still be cheaper. By then, EVs will produce even fewer global warming emissions than gas-powered cars, but the amount of human toxicity of EVs may increase due to larger batteries. Electric vehicles are already cheaper to run and maintain since they have fewer moving parts. The next big challenges to tackle are range anxiety and charging time.

EVs can go between 50 and miles on one battery charge, depending on the make of the car. Cohen thinks that when EVs get to miles per charge—which may not take long, considering EV ranges have already doubled within the past three or four years—it will be a game-changer. These developments will lessen the environmental impacts of EVs and improve their efficiency. And as battery prices continue to fall battery pack prices fell 74 percent between and , consumers will get more range for their money and EV prices will come down.

The time it takes to charge an EV today can range from 30 minutes to 12 hours, depending on the capacity of the battery and the speed of the charging station. Multiple companies are already working on next-generation fast chargers, which will be able to recharge EVs with a to mile range within 15 minutes.
Currently there are about 17, charging stations in the U.

Solar and wind, which now generate about 10 percent of power in the U. In addition, as batteries improve , wind and solar power are becoming more reliable. To promote the growth of electric vehicles, the right policies are also key.
Tax credits for purchasing EVs must be continued. Fuel efficiency standards are necessary to spur automakers to produce clean and efficient cars.
Though it is an ambitious plan, getting the supporting infrastructure up and running will be a major challenge. Besides, one more aspect and that too a very important one is whether the switch over to EVs is really serving the purpose for which they were basically put on the roads? Yes, we are discussing about whether the switch over to EVs will actually make a difference in emissions, whether it will help in reducing air pollution?
Well, the answer lies in the fact that an EV will only be as green as the electricity it runs on. For instance, lets take the example of a country like Norway. Large- and small-scale hydro, wind and biomass make up for the rest. With only a small share of power sourcing coming from renewables, and electrification of mobility gathering steam in the near future, the potential impact of EVs on electricity cannot be ruled out.
This results in very low maintenance compared to a fossil fuel powered vehicle. Recently there has been much hype around EVs what with the Indian government pledging to replace all petrol and diesel cars with EVs by Though it is an ambitious plan, getting the supporting infrastructure up and running will be a major challenge.
