With new major spending packages investing billions of dollars in electric vehicles in the U.S., some analysts have raised concerns over how green the electric vehicle industry actually is, focusing particularly on indirect emissions caused within the supply chains of the vehicle components and the fuels used to power electricity that charges the vehicles.
But a recent study from the Yale School of the Environment published in Nature Communications found that the total indirect emissions from electric vehicles pale in comparison to the indirect emissions from fossil fuel-powered vehicles. This is in addition to the direct emissions from combusting fossil fuels —either at the tailpipe for conventional vehicles or at the power plant smokestack for electricity generation—showing electric vehicles have a clear advantage emissions-wise over conventional vehicles.
“The surprising element was how much lower the emissions of electric vehicles were,” says postdoctoral associate Stephanie Weber. “The supply chain for combustion vehicles is just so dirty that electric vehicles can’t surpass them, even when you factor in indirect emissions.”
ISTANBUL/ADDIS ABABA, Dec 22 (Reuters) — U.S. authorities have taken issue with Turkey over its sales of armed drones to Ethiopia, where two sources familiar with the matter said there was mounting evidence the government had used the weapons against rebel fighters.
Washington has “profound humanitarian concerns” over the sales, which could contravene U.S. restrictions on arms to Addis Ababa, a senior Western official said.
The year-long war between Ethiopia’s government and the leadership of the northern Tigray region, among Africa’s bloodiest conflicts, has killed thousands of civilians and displaced millions.

The team solved this mystery with the help of a vacuum chamber, many lasers, and one powerful cosmic reaction.
But strangely, this green shade disappears before it reaches the one or two tails trailing behind the comet.
Astronomers, scientists, and chemists have been puzzled by this mystery for almost 90 years. In 1930, it was suggested that this phenomenon was due to sunlight destroying diatomic carbon. The carbon is created from the interaction between sunlight and organic matter on the comet’s head. However, due to the instability of dicarbon, this theory has been hard to test.
Scientists at UNSW Sydney have finally found a way to test this chemical reaction in a laboratory – and in doing so, has proven this 90-year-old theory correct. They solved this mystery with the help of a vacuum chamber, a lot of lasers, and one powerful cosmic reaction.
However, the weather in French Guiana isn’t looking good.
