Over 30 years, a town replaced much of the coal used to heat its buildings with bio-fuel made from plant material.
Which is the best explanation for the town's change in heating resources?
Coal reserves are finite, whereas the plant material used for bio-fuel can be grown again.
Coal output depends on changing weather, whereas bio-fuel provides heat continuously because it is renewable.
Burning coal releases carbon dioxide, whereas burning bio-fuel releases no carbon dioxide at all.
Coal cannot be stored for later use, whereas bio-fuel can be stored until heating is needed.
