The energy debate – True or false

Biofuels release carbon dioxide when burnt, similar to fossil fuels. However, the plants used for biofuels absorb carbon dioxide during growth, making biofuels carbon neutral. This means they do not add new carbon dioxide to the atmosphere, unlike fossil fuels.

What is a common misconception about biofuels when they are burnt?

• They release no carbon dioxide.

• They are completely renewable.

• They release more carbon dioxide than fossil fuels.

• They are more efficient than fossil fuels.

How do biofuels compare to fossil fuels in terms of carbon dioxide emission?

• Biofuels release no carbon dioxide.

• Biofuels release less carbon dioxide than fossil fuels.

• Biofuels release more carbon dioxide than fossil fuels.

• Biofuels release carbon dioxide just like fossil fuels.

What role do plants play in the carbon cycle of biofuels?

• They have no role in the carbon cycle.

• They absorb carbon dioxide from the air.

• They release carbon dioxide into the air.

• They convert carbon dioxide into oxygen.

Why are biofuels considered carbon neutral?

• The carbon dioxide they release is offset by the carbon dioxide absorbed by plants.

• They are more efficient than fossil fuels.

• They do not produce any emissions.

• They are made from renewable resources.

What is the main environmental benefit of using biofuels?

• They are easier to produce than fossil fuels.

• They do not require any land to produce.

• They do not contribute to new carbon dioxide in the atmosphere.

• They are cheaper than fossil fuels.
