is using electric cars better for the environment?
9731
Research has shown that electric cars are better for the environment. They emit less greenhouse gases and air pollutants over their life than a petrol or diesel car. This is even after the production of the vehicle and the generation of the electricity required to fuel them is considered.

electric cars are much cheaper to run based on fuel costs alone. And when you factor in maintenance costs, electric starts looking like an even more attractive option – brake systems tend to last longer than on conventional vehicles, and electric vehicles (EVs) have fewer fluids to change, and far fewer moving parts.

The potential of renewable energy sources to power electric vehicles can contribute to a considerable decarbonisation of the future road transport sector and improved resource efficiency. It also has associated co-benefits in terms of reduced air pollution.

Electric motors and batteries add to the energy of electric-car manufacture. ... The same MIT study noted that the materials used in batteries are harmful to the environment. The mining and processing of metals such as lithium, copper, and nickel requires much energy and it can release toxic compounds.

Yes there is pretty much a fossil fuel backbone to all of this for now. However a typical car engine is about 25% efficient. An electric motor is typically greater than 90%. So overall you will get less emissions with the EV, even in areas with heavy coal.

We found that in all states, EVs generate fewer greenhouse gasses than the average gasoline powered vehicle by at least 20%. ... Nationwide EVs are over 60% cleaner than the average gasoline powered vehicle.

It concludes that the global warming potential of the process used to make electric cars is twice that of conventional cars. ... The study concluded that the increased environmental impacts of manufacturing the battery electric technology is more than offset with increased environmental performance during operational life.

Mostly false: “Electric cars generate higher emissions than diesel cars” According to a study conducted by the Ifo, under the leadership of German physics professor Christoph Buchal, the CO2 emissions of electric vehicles are higher than those of diesel cars.

EVs help reduce this threat because almost all U.S. electricity is produced from domestic sources, including coal, nuclear, natural gas, and renewable sources. EVs can also reduce the emissions that contribute to climate change and smog, improving public health and reducing ecological damage.

Higher CO2 emissions than diesel cars It is said that an EV can harm the environment by up to 28% more than conventional diesel engines.

With electrical vehicles already producing fewer emissions through their lifetime regardless of the energy source, it shows that EVs are indeed the vehicle of the future. Car manufacturers are also accepting the fact that electric cars are less polluting and producing more EVs will help reduce total carbon emissions.

They have lower operating and maintenance costs, produce little or no local air pollution, reduce dependence on petroleum and also have the potential to reduce greenhouse gas emissions. ... Since electric cars are heavier on average, they could produce more of this type of pollution than traditional vehicles.

Although electric cars are generally more expensive to buy than internal combustion engine equivalents, their lower running costs (and obviously their lower environmental impacts) mean they are still an attractive alternative.

Lifecycle emissions aside, EVs beat ICEs on air quality, hands down. A study co-authored by Posen, still under peer review, found that replacing all the cars in the Greater Toronto and Hamilton Area with EVs would have “enormous health benefits” even if none of the charging electricity was generated by renewables.

Electric vehicles are supposed to be green, but the truth is a bit murkier. Mining lithium for batteries, plus the power source they're charged from, affects an EV's impact on the environment.

In states that use more clean power sources, electric cars are going to create fewer emissions than hybrid cars. ... However, they also found that in 11 states that rely on more clean and renewable energy sources in their grid, driving an electric car is better for the environment than driving a hybrid or conventional car.

While the green credentials of electric cars vary depending on how that electricity is generated in the first place, they still have lower CO2 emissions overall. Manufacturers are now convinced that they can build electric cars with a comparable range and speed to their petrol counterparts.
