Electric vehicles are more environmentally friendly than thermal engine vehicles

I would like to offer some counterpoints to recent letters from the Gazette (“Nothing Green About the Green New Deal”, July 29, and “How We Can Tackle the Climate Crisis”, August 10), which asserted that electric vehicles consume excessive energy. energy in their production, rely primarily on fossil fuel-derived electricity sources and incorporate toxic materials.

The implication was that electric vehicles are no better for the environment than combustion engine vehicles. First, with regard to energy use and carbon emissions in manufacturing, a detailed 2022 study from the Yale School of the Environment found that total indirect carbon emissions from electric vehicles, including operation mining, manufacturing and other supply chain processes, are actually far inferior to those of conventional vehicles. combustion vehicles.

Second, when it comes to burning energy sources derived from fossil fuels, it is true that EVs indirectly consume all energy sources that feed into the electrical grid. However, electric vehicles use this energy much more efficiently than combustion engine vehicles.

According to the U.S. Department of Energy, electric vehicles convert about 59% to 62% of electric power from the grid into power at the wheels, while gas-powered vehicles only convert about 17% to 21% of the energy stored in the gasoline into energy at the engine level. wheels. So even without taking into account the ever-increasing share of renewable electricity in the US electric grid, electric vehicles use less fossil fuels.

Third, when it comes to toxic materials in EV batteries (in many cases mined with environmental and social operating processes), that is indeed a concern, but harmful manufacturing processes are not unique to VE.

And, there are encouraging developments. Startups are developing and building lithium-ion battery recycling facilities to extract valuable components for reuse in new batteries. Additionally, improved solid-state batteries with fewer toxic materials are being developed for electric vehicles that could outperform and eventually replace lithium-ion batteries.

I would say electric vehicles are the way to go.
