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.

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

• They emit less carbon dioxide

• They emit the same amount of carbon dioxide

• They do not emit carbon dioxide

• They emit more carbon dioxide

What does it mean for a fuel to be carbon neutral?

• It does not produce energy

• It does not contribute to the increase of carbon dioxide in the atmosphere

• It is derived from renewable sources

• It is more efficient than fossil fuels
