‘Biofuels are likely to make an important contribution to a reduction in global greenhouse gas emissions.’ Evaluate this statement using the evidence provided. The opinion on biofuels is largely mixed‚ and it is questioned how effectively they will impact on the reduction of greenhouse gas emissions. The Department for Environment‚ Food and Rural Affairs [DEFRA] (2003) claim that biofuels are sustainable and renewable to a large extent‚ as they are made from recycled elements of the food chain

There are more of the renewable fuels to use like biofuels and biomass we have to wonder how all of this will affect the ever changing of the environment. There are several different environmental problems of biofuels and biomass in

Biofuels Vehicles that run on biodiesel get thirty percent better fuel economy than gasoline-powered vehicles (Perritano). The many forms of biofuels make it easier to obtain and use. Biofuels are better for the environment because they reduce greenhouse gas emissions. For example‚ ethanol reduces greenhouse gas emissions up to sixty-five percent (Perritano). Biofuels are a source of energy from plants that can help fuel our vehicles and our lives. A biofuel is any fuel that is made from plant

United States is still dependent on fossil fuels; we have been working vigorously toward alternative energy. In the future the goal is to be completely independent from fossil fuels. Alternative energy has many different kinds of sources such as biofuels‚ hydrogen‚ solar‚ geothermal‚ and nuclear energy. With such a vast amount of resources to choose from and research‚ it is hard to believe that fossil fuels will be an effective choice of energy in the future. Fossil fuels are not only limited

wind energy and biofuel energy. Wind energy uses turbines which convert the kinetic energy in the wind into mechanical power. This power can be used for a generator‚ a generator can convert this mechanical power into electricity to power homes‚ businesses‚ schools‚ and many others. Biofuel energy unlike other renewable energy sources can be converted directly into liquid fuels for our transportation needs usually found from dead plants and animals. The two most common types of biofuels are ethanol

around the world‚ but particularly industrialized or developed countries are encouraging the production of biofuels or agrofuels. However‚ the production of biofuels has different social‚ economic and environmental impacts in each country depending on its natural resources used for production as well as social and political structures in each region. There are two main fuels considered as biofuels‚ which are bioethanol and biodiesel. Biodiesels are fuels that are‚ in essence‚ biodegradable and non-toxic
