Electric car motors have higher initial costs, lower costs of recharging and maintenance, higher economic life, and are safer for the environment than gasoline engines. Although gasoline engines are high-maintenance, detrimental to the environment, and have high costs of refueling, they are currently more reliable and have lower initial costs than electric car motors. A drop in the price of gasoline, such as the one experienced in 2015, lowers the cost of refueling mainly in favor of gasoline engines.
As a relatively new technology, electric car motors have higher initial costs than internal combustion engines. Electric car motors become cost-effective over time because they have lower costs of recharging and require little maintenance. Gasoline engines may be cheap initially, but their costs increase faster over time due to high refueling and maintenance costs. The useful life of gasoline engines is short compared to their counterparts, but gasoline engines are more reliable because they hold fuel over a longer distance. Moreover, there are more gasoline outlets than recharging spots for electric car batteries.
As concerns the environment, electric car motors are favorable. Gasoline engines account for about 20 percent of total greenhouse emissions as of 2015. Although electric car motors have zero emissions, the source of the electricity determines the overall impact on the environment. If recharging outlets use electricity from coal plants, the emissions from the technology increase. Additionally, electric cars rely on batteries whose production involves the extraction, refining and disposal of hazardous elements. Despite these downfalls, electric car motors are less detrimental to the environment than gasoline engines.
