Biofuels: Are they the Future?
Everything humans need come from our planet whether it is food, water, metals or fuels. It has been determined that if we use up any one of these resources then we will be without forever. Fossil fuels, coal, oil, and natural gas are non-renewable resources. Formed from plant and animals that lived up to 300 million years ago, fossil fuels are found in deposits deep beneath the earth. The fuels are burned to release the chemical energy that is stored within this resource. Energy is essential to our modern technology based society. Currently over 82% of our energy demands are met by combustion of fossil fuel. (EIA, 2014) Coal provides 18%

The stem that has passed through the power station’s turbines must be cooled to condense it back into water before it can be pumped again. Therefore, there are huge cooling towers seen at power station. And so, they are usually built on coastal areas in order to access the vast amounts of water to cool the steam. However, this warms the lake or ocean water and can affect the environment.
Advantages of fossil fuels:
• Large amounts of electricity can be generated in one place using coal at a cheap price.
• Transporting oil and gas to power stations is easy.
• Gas fire power stations are very efficient.
• A fossil fuel power station can be built anywhere if you can get the fuel to it. Coal is delivered by large coal trains called a “unit train” which can be over a mile long containing 140 cars containing 15 tons.

• They use energy that otherwise might be wasted, or converted hazardous gases into energy that would otherwise be released into the atmosphere and create extra pollution.
• All biofuels are safe to handle and store due to their high ignition point.
• The advantages of biofuels include their contribution in conserving fossil resources and the reduction of greenhouse effect since biofuels are more favorable in energy balance and greenhouse gas balance as compared to fossil fuels.
• Biofuels are renewable and a sustainable source as the fuels from organisms that can be grown again. These organisms are mainly plants and wood, although algae. The United States has been faced with a shortage of fossil fuels and needs to find an alternative energy source. An ecological friendly and abundant source of alternative fuel comes from biodiesel. One current method that is still in early stages is obtaining biodiesel is the extraction of oil from microalgae. Currently scientists have found ways to extract oil from algae and convert it into fuel. This innovation of biofuel has the full support of the U.S. Department of Energy whom pledged $24 million dollars in

    Ethanol is an alternative fuel which can solve the most harmful issue with fossil fuels, it’s renewability. Ethanol is a renewable fuel with a complete cycle making it reusable. Since the production of ethanol is plant material the glucose inside the plant is synthesised from CO2 and water by photosynthesis, yeast fermentation generates ethanol from glucose (ehow.com). Ethanol is then used as an energy source and combusted which then produced CO2 and water completing the cycle with plants converting the CO2 and water back to glucose (ehow.com). With this cycle making ethanol renewable makes it a good alternative fuel to fossil fuels which are not…

    Thus for a relatively fast solution many nations are using renewable energy initiatives as an alternative for fossil fuels. Resources for renewable energy include sunlight, wind, rain, tides, waves, and geothermal heat. While renewable energy accounts for a minority share of the world 's energy supply, it is also the fastest growing energy supply on the planet. Renewable energy is sought after because it 's a clean source of energy; that means it doesn 't directly produce greenhouse emissions or air pollutants. The best part is that we don 't need to compromise our planet or harm it.…

    The topic of energy I chose to do my paper on was fossil fuels and their impact. For those of you who may not know what fossil fuels are they are formed by natural processes. They are hydrocarbons generally coal, fuel oil which come from dead organisms like plants and animals. These fuels became well recognized and in use following the 18th century’s industrial revolution. Since then we’ve seen the fossil fuels used more and more.…

    In this team paper, I choose the topic on the fossil fuels energy. The fossil energy is including petroleum, natural gas, and coal. They are three major use resources in the past few decades. The reason for them to be the main resources because they can transfer into different energies. So that make them to be more ways to use in our daily.…

    Fossil fuel use must be progressively phased out while renewable fuels are implemented. All the proven sources of oil will be depleted by the year 2055 per Erika Antoniazzo, an author of the website, eco-info.net, who is informed about oil production. One could argue that renewable resources can never be depleted. There will always be wind that can blow turbines. There will always be a sun to heat solar panels.…

    The obvious answer would be we would if we were able too. But that is not the case since fossil fuel is a natural made substance and process which we can’t recreate. To begin it takes hundred million and millions of years to make. It’s made from decaying plants and remains of living organisms that are buried under several layers of earth. Once under so many layers of immense amount of pressure and exposure to the earths heat the decomposed remains turns it to fossil fuel.…

    Nuclear Power For The Future The earth is running dry. People are quickly exhausting the fossil fuels that took millions of year to create. With this imbalance, the people of earth will soon be forced to find energy in other forms. While many options are available, the most efficient and cost effective is nuclear. Currently the United States only gets a small portion of its power from nuclear energy, and this needs to change.…
