Electric Vehicles vs the Environment
Electric, Hybrid, Plug-in hybrid and 'solar powered'...
From point to point the idea of clean, quiet vehicles sounds great. For the user, the experience seems friendly to the little bunnies and flowers around us. But what about when we consider the building and disposal of such electric vehicles, are they still green compared to a traditional combustion engine vehicle?
Usage vs Production
More CO2 emissions are produced to manufacture EV cars compared to ICE cars, primarily due to the batteries.
Disposal
Life Cycle Emissions
the extra emissions associated with electric vehicle production are rapidly negated by reduced emissions from driving. Comparing an average midsize midrange EV with an average midsize gasoline-powered car, it takes just 4,900 miles of driving to “pay back”—i.e., offset—the extra global warming emissions from producing the EV. Similarly, it takes 19,000 miles with the full-size long-range EV compared with a similar gasoline car. Based on typical usages of these vehicles, this amounts to about six months’ driving for the midsize midrange EV and 16 months for the full-size long-range EV.
Meanwhile, the global warming emissions of manufacturing BEVs are falling as automakers gain experience and improve production efficiency. With a focus on clean manufacturing, emissions could fall even more. There are many ways in which the EV industry might reduce these manufacturing-related emissions, including:
Advances in manufacturing efficiency and in the recycling or reuse of lithium-ion batteries;
The use of alternative battery chemistries that require less energy-intensive materials; and
The use of renewable energy to power manufacturers’ and suppliers’ facilities.
Are electric cars really better for the environment?
Pull-ution
Are we merely sliding the responsibility and pollution further away to other parts of the industry, pulling the creation of emissions upstream?
