Electric vehicle can impact climate change
Is it possible for electric vehicles to improve air quality and climate outlook? Recent research has thrown light on the efficacy of electric vehicles.
The study published in the journal Atmospheric Environment provided evidence that making a switch to electric vehicles would improve overall air quality and lower carbon emissions. The study quantified the differences in air pollution generated from battery-powered electric vehicles versus internal combustion engines.
The researchers found that even when their electricity is generated from combustion sources, electric vehicles have a net positive impact on air quality and climate change.
To quantify the differences between the two types of vehicles, the researchers used emissions remapping algorithm and air quality model simulations.
They used these methods to closely examine two pollutants related to automobiles and power emissions: ozone and particulate matter. Both are main components of smog and can trigger a variety of health problems, such as asthma, emphysema and chronic bronchitis.
To fully account for the complexity of changes to air pollution chemistry, the researchers took multiple variables into consideration including potential electric vehicles adoption rates, Generation of electric vehicle power supply, including our current combustion-dominant mix, combustion-only sources and enhanced emission-free renewable, geographical locations, and seasons and times of the day.
