There are several potential drawbacks. If the biofuel is ethanol, then the entire fuel distribution infrastructure and fleet of vehicle engines need to be changed in order to accomodate ethanol, which is more corrosive than gasoline. Moreover, the fuel needs are so large that replacing gasoline with biofuels requires an immense amount of land, which can compete with farmland for food, particularly of corn is used as the biofuel feedstock. Biofuels made from cellulose (the cell walls of plants) reduces this issue slightly. Biofuel production from algae shows some potential but still faces a number of challenges, particularly related to land and water use.
Sugar cane is used to make ethanol and sugar cane is a renewable energy resource, it also reduces certain greenhouse emission.
You need energy to survive

No, WikiAnswers will not do your homework for you. That's cheating. Make a list of all the positive things about renewable energy -- you're going to have to do some work and research this using your textbook! -- now pretend you're telling a friend all about these things and trying to convince them to use renewable energy. There's your letter.
The energy crisis can be overcame by the following methods: 1) Increase the use of renewable energy sources such as sunlight, wind, tides etc. 2) Reduce the use of non-renewable energy sources such as petroleum, coal, natural gas etc. 3) Avoid the wastage of energy such as burning street lights at daytime, using car or bike for going to a walkable distance etc.
No, biomass, biogas, biodiesel and other biofuels are all renewable.
Renewable energy can't run out. Non-renewable energy WILL run out. Renewable energy is produced at a constant rate, non-renewable is not. Renewable energy is free when the generator is built, non-renewable is not. Renewable energy does not cause pollution (with the exception of biofuels), non-renewable energy does.
Biofuels , Solar energy , Wind energy , Tidal energy are examples of some renewable energies
Biofuels are fuel made from any plant or animal based products. Two traditional biofuels are wood and corn. Biofuels are renewable sources of energy.
renewable or renewable resource
Electricity is generally a product of an energy source. It is renewable if it is coming from biofuels or solar, wind, nuclear, or hydropower, but not if it is from coal, oil, or natural gas.
Uranium is not a renewable energy resource however their is enough of it that it counts as an 'Alternative Resource'.
Oil, the fossil fuel, is a non-renewable resource on human time scales. Vegetable oil is a renewable resource. An inexhaustible resource would be sunlight and a renewable resource would be wind energy and solar energy.
it is a renewable resource
its renewable
renewable resource
it can be either renewable or nonrenewable resource.
