Electric vehicles (EVs) are a strong weapon in the world’s efforts     1     global warming, But the effects of EVs depend on which country you are in, new research shows.

The researchers compared gas emissions (排放) caused by charging an EV to drive 100 kilometers with the emissions     2     (come) from an average gasoline car driven the same     3     ( distant).

Countries     4     charging an electric vehicle is     5     (clean) than driving a gasoline-powered car use a lot of hydroelectric (水电), nuclear or solar power. Data suggests that an electric vehicle in Poland actually     6     (create) more carbon emissions because its electric system depends so much on coal. In other European countries, however, EVs result in reduced emissions.

Germany creates a lot of electricity from the sun and wind. But they do not add to the electricity system     7     (equal) throughout the day. For this reason, the amount of carbon emissions saved by driving an EV depends on the time of day when it     8     (charge). Charging in the afternoon, when there is more sun and wind, saves 16 to 18 percent more carbon than at night when electricity systems are more likely     9     (use) gas or coal.

The gap in emissions between electric and gasoline powered vehicles has narrowed in recent years. In Europe, carmakers have been required to meet EU carbon reduction standards. They have made their gasoline engines more fuel-efficient. As     10     result, the carbon emissions of new gasoline-powered cars in Europe fell by an average of 25 percent between 2006 and 2016.
