Question

Ray bus is like ,most buses, powered by petrol engine.these buses contribute to environmental pollution
Some cities have trolley buses: they powered by an electric engine . The voltage needed for such an electric engine is provided by overhead lines ( like electric train) the electricity is supplied by a power station using fossil fuel supporters for the use of trolley buses in the city say that these buses don't contribute environmental pollution

Are these supporters right? Explain your answer?

Answer 1

Answer:

yes, it is correct to use trolley buses because trolley is run by electricity through wire then how the fossil fuel is passed in engine, so this this bus will not cause pollution

Answer 2

The supporters are not right.

• The burning of fossil fuels cause pollution.
• The ray buses use fossil fuels directly to run the engine.
• The trolley buses indirectly use fossil fuels. This is because the electricity for the trolley buses is generated in power station using fossil fuel.
• The use of the fossil fuels at the power station also causes pollution.
• So it is false that the trolley buses cause no pollution.
