Andrew steer and craig hanson: biofuels and bioenergy take up finite land resources desperately needed for food production and carbon storage and doesn't guarantee carbon in fact, burning biomass directly emits a bit more carbon dioxide than fossil fuels for the same amount of generated energy. Since these are nonrenewable sources of energy, there has been a steep decline in energy reserves moreover, burning using biofuels three gas pump nozzles use of biofuels such as ethanol or biodiesel could also play an important role in saving fossil fuels ethanol is is the most common biofuel worldwide it can be. On the one hand, reduced dependence on imported fossil fuels and broader development of alternative energy sources can help alleviate some of the current concerns around security of supply for these fuels yet as the demand for decarbonised electricity and also for biofuels increases, so new challenges will no doubt. Fossil fuels, sometimes known as traditional energy resources or nonrenewable energy resources, are formed over millions of years by decayed animal and plant matter buried under rock layers three main types of fossil fuels are coal, oil, and natural gas these fuels are formed depending the amount of animal and plant. Biofuels are not a silver bullet for the energy problems of the world to solve the issue of dwindling fossil fuel reserves, all viable means of harvesting energy should be pursued to their fullest however, the fact remains that biofuels are a reliable alternative energy resource with more development and research, it is.
Solar energy, wind power and moving water are all traditional sources of alternative energy that are making progress in our global society, it simply means energy that is produced from sources other than our primary energy supply: fossil fuels working on an essay right now this helped so much. Free essay: however, when temperatures exceed 160¢ªc, all of the oil in the sources rock burns off to form natural gas fossil fuels essay 2192 words 9 pages fossil fuels energy, whether it was sunlight or heat from a wood fire, has always been important to society however bio-fuels are better than fossil fuels. This means that there is a finite amount of fossil fuels available and the reserves are not replenished naturallythis is not entirely correct, as fossil fuels are products of millions of years of natural processes such as anaerobic decomposition of organic matter the thing is, as opposed to renewable energy sources such as.
Alternative resources for energy instead of fossil fuels essay 544 words | 3 pages alternative resources for energy are being used instead of fossil fuels being used fossil fuels create greenhouse gases which accumulate in the atmosphere and harms it some alternative options for getting energy are using solar, hydro,. So biofuel crops can be used to benefit and enrich farmers and not damage world food prices however, it is certainly reasonable that we do not switch our fuel usage and expect to be able to entirely replace fossil fuel with biofuel a reasonable future will see all sorts of alternative energy sources being.
Biofuel: an alternative to fossil fuel for alleviating world energy and economic crises the time has come when it is desirable to look for alternative energy resources to confront the global energy crisis the recent oil spill in the gulf of mexico is just another example of the environmental threats that fossil fuels pose. High co2 emissions found in limited areas supply may be exhausted before natural gas/coal resources possible environmental impact from drilling/ transporting biofuels abundant supply fewer emissions than fossil fuel sources can be used in diesel engines auto engines easily convert to run on biomass fuel source. Alternative energy is any energy source that is an alternative to fossil fuel these alternatives are intended to address concerns about such fossil fuels, such as its high carbon dioxide emissions, an important factor in global warming marine energy, hydroelectric, wind, geothermal and solar power are all alternative sources.
