Answer:
Biofuels like fuel from microalgae are very costly as compared to fossil fuels.
Explanation:
The cost of biofuels is too high as compared to that of fossil fuel. For instance,
the cost of 1 gallon of algal fuel is $32.81 per gallon while cost of diesel is $2.9 -3.2 per gallon.
However, biofuels are very environment friendly as compared to that of fossil fuels.
Well one thing u could do is to reduce the amount of fossil fuels burning (idk how, maybe finding a better alternative to burning them) another way would be planting more trees, or buy energy efficient products. Basically these things just reduce the carbon footprint by reducing the amount of fossil fuels (because we only have a limited amount) i hope this helped
