Question

The Science Magazine article “The coming electric vehicle transformation” mentions the impacts this may have on (i) the energy system, (ii) geo-economics, (iii) battery development, (iv) material supply chains & (v) the global landscape. For each of these, select & comment on one impact you think is important, &/or interesting.

Answer 1

1. Electric vehicles results in less energy loss compared to gas power engine.Even cooler, electric car brakes don't function the same way that gas-powered car brakes do.Electric vehicles (EV) are 75 percent efficient at turning input energy into moving energy (kinetic energy).
2. Overall, electric cars are significantly cleaner and safer for the environment than traditional gas cars. They produce less greenhouse emissions. Thereby reduce global warming and air pollution. There is no chemicals which penetrate into the soil that cause harm to the plants. Electric car innovation and technology helps grow the economy.While oil prices fluctuate greatly, the depandance on renewable energy sources create less expenditure.
3. The battery, the primary component of electric cars, is a top concern among critics because they have a limited lifespan. They are also toxic if disposed of incorrectly.
4. In every electric vehicle (EV) battery, there’s a complex chemistry of metals – cobalt, lithium, nickel and more.The latest research suggests, they could face a supply crunch by the mid-2020s, increasing the pressure on the raw material supply chain.
