People are becoming informed and concerned about the negative effects of traditional fuel vehicles on our environment. This has influenced many to change over to driving fully-electric cars. With the aim of reducing carbon footprints, noise and air pollution in our cities. However, with so many people now driving electric vehicles, it would be good to know the impact electric vehicles have on the environment and if electric vehicles actually do reduce pollution.
Increased demand for electricity: However, electric cars also require a significant amount of electricity to operate, as you charge your car as opposed to putting in fuel. If this electricity comes from fossil fuel sources like coal or natural gas, then the environmental benefits of electric cars may be limited. You can read more about the advantages and disadvantages of charging a car here โ
Electric cars use lithium batteries that are made up of metals like iron, aluminium, and copper. More critical raw materials are needed to make electric cars than regular gas-powered cars. These materials require a lot of energy to make
Most of the batteries used for electric cars are made in Japan, South Korea and China. In these countries, the use of carbon to produce electricity is higher compared to other countries that manufacture batteries ๐
Studies have even stated that about 35% to 50% of the total electric vehicle manufacturing emissions come from electricity being consumed to produce batteries in China. However, the use of renewable energy in these countries is predicted to rise rapidly during the course of the next three years โ
Around the globe, manufacturers of lithium-ion batteries are encountering difficulties in meeting the growing demand from electric vehicle makers, according to reports. However, this is considered a short-term issue because the electric car industry was caught off guard by the abrupt surge in demand for electric vehicles and their associated batteries.
The extraction of lithium and other metals, as well as the production of batteries, is being rapidly accelerated all over the globe. In 2018, the cost of valuable metals used in the manufacture of EVs decreased following two years of price surges from 2016 to 2017. This indicates that the markets are optimistic about the long-term availability of these precious metals
A well-maintained modern vehicle is expected to run for 150,000 miles or more before its battery starts to lose capacity. But this figure could reduce faster if the car owner uses a rapid charger more often as their charging method.
Electric car owners will eventually have to face recycling and replacing their EV batteries and it might cost them more than the actual value of the car. Also at present, thereโs no standardised process when it comes to battery recycling. If a process can be developed, then it can add weight to the green credentials of electric vehicles. ๐
Studies suggest that innovations in EV battery material recovery can help in reducing 23% of greenhouse gases. Many car manufacturers are starting to act. For example, Volkswagen introduced a scheme in 2019 where they expect to see 97% of all raw materials used in new batteries for EVs be reused by 2040.
If thereโs a way to standardise the recycling technique for EV batteries, as well as test the second-use applications for the batteries, then there is a high potential that can reduce the environmental impact of battery production significantly.
Other than the sources of energy used in the production phase of EVs, an electric vehicle can only be as clean as the power you use to charge it. When it comes to the environmental impact, EVs only become 100% environmentally friendly when they run completely on renewable power.
Whatโs important though is that electric cars have the potential to be a hundred per cent green in the future, from the perspective of driving as well production. Whatโs even better is that energy production is now reaching a crucial turning point.
Back in 2019, the UK was able to clock up its first coal-free fortnight. Hydro plants, biomass, solar panels, and wind farms were able to generate more electricity compared to the combined power produced by gas, oil, and coal power stations. By 2050, it is expected that solar and wind power will have the biggest share of power generation in the United Kingdom.
The environmental impact of EV charging infrastructure depends on factors such as construction materials, energy sources, and charging equipment efficiency. Building charging stations involves using materials that have their own environmental footprints, while the energy consumption of the stations relies on the grid's power sources.
Integrating renewable energy sources like solar or wind power can significantly reduce the carbon footprint of EV charging. Furthermore, advancements in technology and the incorporation of energy storage systems can help make charging infrastructure more sustainable and eco-friendly, ultimately contributing to a cleaner and more sustainable future for transportation.
Government policies and incentives play a crucial role in promoting the adoption of electric vehicles in the UK. These measures include tax breaks, grants and subsidies for EV buyers, as well as funding for charging infrastructure. Supportive policies like the ban on new petrol and diesel car sales by 2030 encourage a shift towards sustainable transport options.
Incentives such as reduced road tax, free parking, and access to low-emission zones further encourage EV adoption. A conducive environment for EV growth helps the government actively work towards reducing greenhouse gas emissions, improving air quality, and meeting climate change targets.
So are electric cars really better for our planet? ๐ค
The answer based on current evidence is that yes, they are. EVs are already making many busy cities cleaner and quieter ๐ค The challenge we have today is to reduce the emissions even further through improvements in EV manufacturing as well as energy production.
When electric cars are more widely used, will be able to experience the full benefit of the green potential of electric vehicles ๐ฑ
