In contrast, fossil fuels are made from organisms which died millions of years ago
3 advantages of biofuels
Renewable
Easy to transport
Can be used in vehicles
2 disadvantages of biofuels
They require a large area of land to grow
Require a lot of energy to harvest, process, and transport
Why are biofuels carbon neutral (in theory)
Absorb the same amount of carbon dioxide while growing as they release when they’re burned
Why are biofuels not really carbon neutral in practice
Lots of land is required to grow biofuels so trees must be broken down meaning less CO2 is being absorbed and more is being released if the trees are burned
