Biofuels would require a large amount of land to be dedicated as farm land to be successful.

Detailed explanation-1: -Biofuel feedstocks include many crops that would otherwise be used for human consumption directly, or indirectly as animal feed. Diverting these crops to biofuels may lead to more land area devoted to agriculture, increased use of polluting inputs, and higher food prices.
Detailed explanation-2: -1: Technical Challenges. Biofuels can be tricky, because they operate differently in cars than regular petroleum-based fuels do. Perhaps the most straightforward of biofuel’s drawbacks is the most obvious: It isn’t petroleum-based fuel, so it will operate differently in engines designed for petroleum-based fuel.
Detailed explanation-3: -One disadvantage of biodiesel is its incompatibility with cold regions. Researchers discovered biodiesel turns into a gel at low temperatures. Drivers are unable to use the fuel source in cold climates. Consumers can only use biodiesel as a fuel source in warm climates.
Detailed explanation-4: -It disturbs the life cycle. Cost of labour and it requires huge space for storage. More water consumption, especially in dry climates. Growing biomass for biofuel production increases the demand for agricultural land.
