Small-Scale Energy Usage Practice Test

Electric cars still contribute to traffic congestion and idling vehicles are a large contributor to greenhouse gas emmissions.

Electric cars are often built in third world countries, where factories and firms are not subject to environmental protection or accountability laws.

If the electricity comes from a polluting source (e.g. coal), then the electric car still contributes to pollution and greenhouse gas emmissions indirectly.

Electric cars are actually not completely electric. They still contain an internal combustion engine and switch to running on gasoline after the electric battery has died or the car reaches a certain speed.

The lithium batteries in electric cars contain toxic chemicals that are difficult to store.
