Does EV help address the energy crisis?
Electric cars (or electric vehicles, EVs) have a smaller environmental footprint than conventional internal combustion engine vehicles (ICEVs). While aspects of their production can induce similar, less or alternative environmental impacts, they produce little or no tailpipe emissions, and reduce dependence on petroleum, greenhouse gas emissions, and health effects from air pollution. Electric motors are significantly more efficient than internal combustion engines and thus, even accounting for typical power plant efficiencies and distribution losses, less energy is required to operate an EV. Manufacturing batteries for electric cars requires additional resources and energy, so they may have a larger environmental footprint from the production phase. EVs also generate different impacts in their operation and maintenance. EVs are typically heavier and could produce more tire and road dust air pollution, but their regenerative braking could reduce such particulate pollution from brakes. EVs are mechanically simpler, which reduces the use and disposal of engine oil.

Although all cars have effects on other people, battery electric cars have major environmental benefits over conventional internal combustion engine vehicles (ICEVs), such as:

Elimination of harmful tailpipe pollutants such as various oxides of nitrogen, which kill thousands of people every year. EVs use 38 megajoules per 100 km in comparison to 142 megajoules per 100 km for ICE cars. Less CO2 emissions globally than fossil-fuelled cars, thus limiting climate change.  Plug-in hybrids capture most of these benefits when they are operating in all-electric mode.

Electric cars have some disadvantages, such as:

Possible increased particulate matter emissions from tires compared to fossil-fueled cars. This is sometimes caused by the fact that most electric cars have a heavy battery, which means the car's tires are subjected to more wear. This is drastically reduced when EV-rated weight-specific tires are used on the EV which are built specifically for the extra weight.[citation needed] Devices to capture tyre particulates are being developed.
The brake pads, however, can be used less frequently than in non-electric cars, if regenerative braking is available and may thus sometimes produce less particulate pollution than brakes in non-electric cars. Also, some electric cars may have a combination of drum brakes and disc brakes, and drum brakes are known to cause less particulate emissions than disc brakes.

Reliance on rare-earth elements such as neodymium, lanthanum, terbium, and dysprosium, and other critical metals such as lithium and cobalt,though the quantity of rare metals used differs per car. Despite the name rare earth metals are plentiful.They make up a tiny share of the minerals used to make a car.
