Growing plants for biofuels is expensive
Ummm . . . windmills use the wind to keep them turning. No biofuels are involved.
Biofuels can compete with food production for land and water resources, leading to potential food shortages and environmental degradation. They can also contribute to deforestation and increase greenhouse gas emissions if not produced sustainably. Additionally, the production of biofuels may not always be cost-effective compared to traditional fossil fuels.
Use as gas
source:(http://en.wikipedia.org/wiki/Biofuel)we use biofuels because they do not make as much pollution as normal fuels.
Biofuels
If they are diesel powered they can.
SG Biofuels was founded in 2007.
I saw deforestation on my way to Africa.
Deforestation clears land for farms and dwellings for people.
The steady increase in carbon dioxide concentrations in the atmosphere come from our use of fossil fuels. If we were able to stop using fossil fuels, the amount of carbon dioxide in the atmosphere would stop rising. Biofuels are a partial answer, because by using biofuels you are reducing our use of fossil fuels.
Biofuels are fuel made from any plant or animal based products. Two traditional biofuels are wood and corn. Biofuels are renewable sources of energy.
