Bio-fuels Essay Example for Free

Bio-fuels EssayAdvantages The actual aim of biofuels is to be carbon neutral. Potentially they can reduce greenhouse gas emissions when you comp ar them to conventional conveyancing fuels, but this ability depends on the way you produce these biofuels. In reality biofuels arent carbon neutral because they actually require energy to grow the crops and to metamorphose them into fuel. However, biofuels could still be more environmentally friendly then early(a) fossil alternatives. They can save up to 60% of the carbon emissions compared to fossil fuels, and back up generation biofuels can purport savings of about 80%. Another advantage of biofuels is that they save money of drivers. Governments pick out introduced many incentives to drivers of the well-k outrightn green cars who are based on emissions, who come with reduced taxation. And because the petrol prices are rising, if you then would replace the petroleum with a renewable energy source it should actually offer high s avings at the pump in the long term, especially when the availability of biofuels will rise.Disadvantages However, there have been some arguments that biofuel isnt as affirmative as it had been portrayed and thought of. The following points are some of the several concerns about biofuels * Biodiversity This has been feared a lot lately, because when adapting more land to produce the crops needed for biofuels, the essence would be that more habitats would be lost for animals and wild plants. * Food versus fuel debate Another concern is that if biofuels become attractive for farmers theyll decide that they may emergency to grow crops for biofuel production instead of for food production. If less food is produced that will lead to the increase of prices and also cause a rise in inflation. A way to counter this problem is by second generation biofuels which use waste biomass, but then again that will also impact the habitat of many organisms. Due to the food price increase, around 1 00 million people are at risk and then especially in the ontogenesis countries.* Carbon emissions Most of the investigations do indicate that by burning biofuels it does actually reduce the greenhouse gas emissions when you would compare it to petroleum and diesel. only if lately studies have been published that show that the burning of e.g. corn can contribute as much to nitrous oxide emissions than cooling through fossil fuel savings.* Non-sustainable biofuel production some first generation biofuels arent sustainable. And it is necessary to create biofuel production that doesnt affect the production of food and also what doesnt affect any other environmental problems. And because there has been lots of criticism of the production of non-sustainable biofuels many governments have switched their support to sustainable biofuels and other alternatives.Why controversial? Biofuels have been blamed for move up the food prices, that they couldnt meet the environmental standards, they themselves have caused for the demand of water and nitrate fertilizers and they have encouraged the destruction of natural habitats e.g. the rainforest. And still its an controversy which governments have been struggling to solve. What has also been revealed is that the companies who actually use biofuels havent been able to fully report the sustainability of them. But even though we classify environmental damage with the production of biofuels we should not immediately think that all biofuels are bad. The production of biofuels is still developing, and as new fuel technologies are be made the situation could radically change and we may be able to adjust the impact on the environment to a small percentage.After having seen the appointed and negative sides of biofuels you could wonder is biofuels are really worth it. On one hand they could actually reduce the carbon emissions and help save you some money. But they also negatively impact the habitat of many species and arent necess arily efficient enough at producing the energy that they are required to make. So there are two completely different sides to biofuels which explains why the topic biofuels has been so controversial lately in the 21th century and why we are all now discussing if we should go on producing biofuels or not.
