As a domain expert with a focus on sustainable energy, I've been closely monitoring the development and impact of biofuels. Biofuels, derived from biological materials, are designed to be a cleaner alternative to fossil fuels. However, despite their potential benefits, there are several drawbacks associated with their production and use.

Firstly, the land use change** associated with biofuels can be significant.

While biofuels produced from agricultural crops can generate less pollution and greenhouse gas emissions than conventional fossil fuels, in practice, scientists are finding that some are causing environmental problems. Biofuels may also be hurting the poor.read more >>
