Researchers have published new findings and data that should hopefully put to rest damaging myths about electric vehicle emissions. According to a BBC story, studies from two European universities found that electric cars are environmentally superior in 95 percent of the world, with the exception of regions where coal is still largely used to generate electricity.
Renewable energy in general is in a transitional period, and this is perhaps best illustrated by the number of electric vehicles that still use a little amount of fossil fuels—or a lot if you've been driving the Nürburgring in your Chevy Volt. Covering any new study or technology regarding electric cars, nuclear plants, or different kinds of solar.
The results, according to the BBC, are that “the researchers say average ‘lifetime' emissions from electric cars are up to 70 [percent] lower than petrol vehicles in countries like Sweden and France (where most electricity comes from renewables and nuclear), and around 30 [percent] lower in the UK.”
By 2050, the scientists believe, a carbon-neutral future will be within reach. The passage of time and improvements in vehicle technology will continue to reduce transportation emissions from today's levels, but it will take years before they achieve best performance. It is critical to this transition period when emissions numbers are better—but not yet greatest—and when many governments.
Despite this, there are significant challenges. Because of the small number of renewable energy vehicles on the road today, their grids aren't being taxed to capacity, but if everyone swapped in a Tesla or a Nissan Leaf instead of a fossil-fuel automobile, the grid would certainly be pushed back into the demand region, where many more places would use more coal.
The innovative new “backup battery” farm in rural southern Australia run by Elon Musk, and technology to assist isolate and softly dim tiny areas under strain, might offer a path forward for grids that would otherwise rely on coal generation as backup.
It's also significant because it demonstrates that much of the world now has enough renewable energy to support such research, implying that renewables are making inroads in almost every sector and at every scale. We may accomplish far better if we follow through on more stringent, sooner emissions goals than the widely accepted 2050 deadline, according to the researchers.
