How does an electric car's environmental impact depend on its energy source?

Back

An electric car's environmental impact is lower if charged with renewable energy sources; if charged with coal-generated electricity, its impact is higher due to emissions from coal.

Front

What is the process of modifying vehicles to run on alternative fuels?

Back

Modifying vehicles to run on alternative fuels involves adjusting the engine and fuel system to accommodate fuels like ethanol or biodiesel.
