we use biofuels because they do not make as much pollution as normal fuels.
Ummm . . . windmills use the wind to keep them turning. No biofuels are involved.
Use as gas
Biofuels
If they are diesel powered they can.
In order to grow the crops required to produce biofuels more forests need to be knocked down to make the necessary fields.
SG Biofuels was created in 2007.
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.
Growing plants for biofuels is expensive
Yes, planes can use biofuels as a more sustainable alternative to traditional fossil fuels. Biofuels, derived from renewable sources such as plants and waste materials, can help reduce greenhouse gas emissions and dependency on fossil fuels in aviation. Several airlines and aircraft manufacturers have successfully tested and implemented biofuels in commercial flights, contributing to the industry's efforts to achieve greater environmental sustainability. However, the widespread use of biofuels in aviation is still in the early stages and faces challenges related to production and scalability.
The most common use is of the seeds or grain, but there are new processes being researched which can utilize the entire plant in the production of biofuels. One example is cellulosicethanol.
I know that biofuels are renewable because they are derived from plant material. Those plants use sunlight, which is an inexhaustible source. I'm not so sure but that should clear things up.
