Biomass Abstract: The current use of energy in the United States, especially California, is foreshadowing catastrophe in our environment. Due to high demand of fossil fuels, the air is filled with more pollution every day. In addition to, it can increase the chances of having global warming. Since fossil fuels are generated from raw materials which are easy and cheap users are becoming extremely dependent on them. The main problem with fossil energy is that the supply of fossil fuels is not continuous. However, alternative energy is continual and harmless to the environment. Biomass does not pollute the atmosphere as much as natural gas. One of the most convenient alternative energies that are currently used for minor purposes is biomass. From the significant results of recent and past use of biomass, it can be considered trustworthy as the main source of energy in the future. Introduction: The energy that we use presently has raised numerous questions, whether or not it would bring us danger. Thus, scientists tried to find new types of energy that we can use in the future that would not increase the chances of having global warming for other environmental crises. Renewable energy has been examined and tested for many years; and, it [has been proven that it is much better than fossil fuels. Types of renewable or alternative energy include wind power, solar power, and geothermal energy (About, Alternative Energy Resources 2007). Particularly, biomass, “in the energy production industry, refers to living and recently dead biological material which can be used as fuel or for industrial production. Most commonly, biomass refers to plant matter grown for use as biofuel, but it also includes plant or animal matter used for pr... ... middle of paper ... ...w.eia.doe.gov/kids/energyfacts/sources/renewable/biomass.html Biomass (2007).

Introduction:The idea of biofuels is a old concept, reaching as far as the ending of the 19th century. Solid in its idea but flawed in its presentation. Biofuels are a alternative energy to fossil fuels that are made from natural methods such as plants and crops and are key in solving the apparent flaws of fossil fuels. While fossil fuels have been in use for over a century, Biofuels have now risen to the popularity and been exposed to the press. At one point of time biofuel were being considered by some of the most brilliant minds ever in human history such as Henry Ford and Rudolph Diesel who believed that biofuels had the potential to be the new evolution s on only to reappear a century later. Now the world faces the struggles of global warming and the depletion of fossil fuels slowly dimming by day. Throughout the last century biofuels have proven to have a place in our society as a new alternative fuel source. Specializing in Being Natural and healthier than fossil fuels, biofuels have had a rough beginning against its competitor due to key situations such as pricing, Side effects, to fuel power. However the idea was passed on a to the later generations, and continued to pasand prolong usage. However through the last decade they have been highly advertised by politicians and Government officials claiming it to be the future of a powerful working society, and to help in making a new energy free world. Through belief Some even claiming that “By 2050, a new generation of sustainable biofuels could provide over a quarter of the world’s total transport fuel, according to a recent report by the International Energy Agency” (last name). With such improvement biofuels should be the obvious answer to providing a better future to th...
...lobal warming and innumerable animal fatalities worldwide. Workers in the fossil fuel industries undergo irrational risks of an inevitable explosion every day. Thousands of human lives have been taken in offshore oil rig explosions, coal mines and natural gas pipelines. In addition, fossil fuels are directly linked to rising global warming temperatures and drast changes in the environment. Likewise millions of avian fatalities were linked to fossil fuels plants, emitting greenhouse gases are responsible for acidic oceans that harm marine species, and thousands of animals are harmed by oil spills in the sea. Based on this research, fossil fuels are harming the Earth excessively. Renewable energy sources offer efficient and cleaner energy that will benefit the globe. Renewable energy is the definite solution to end human’s heavy dependence upon ancient fossil fuels.
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
In addition to the fact that solar, wind, and hydro power are local resources, they are also emission free resources. Emissions and pollution are a key concern with traditional power sources. The coal-fired plants that dominate U.S. energy production also produce more emissions than any other energy source. “Em...
Energy, especially from fossil fuels, is a key ingredient for all sectors of a modern economy and plays a fundamental role in improving the quality of life in less developed economies. In 2007, India is ranked fifth in the world in terms of energy demand; accounting for 3.6% of total energy consumed, and is expected to grow at 4.8% in the future. India imports 70% of the oil it uses, and the country has been hit hard by the increasing price of oil, uncertainty and environmental hazards that are concerned with the consumption of fossil fuels. In such context, bio energy constitutes a suitable alternative source of energy for India, as large amounts of raw material are available to be harnessed.
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
In contrast, most renewable energy sources produce little to no global warming emissions (“Benefits of Renewable Energy Use”). Coal mining and lumber harvesting would also be reduced by the switch, which in turn would improve the forest and ecosystem surrounding these power plants. Animals will also benefit from the change to clean energy. It is often reported that animals are constantly displaced and injured by the different forms of energy we are currently using. Andrew B. Gill performed a study and wrote a journal article on the conservation of wildlife and their habitats; the results of his study were conclusive that something needs to be done to change the current state of our energy resources.
Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern society, but since they are non-renewable and dangerous, we should reduce our dependence on them and explore alternative energy sources. Wind energy, hydroelectricity, and solar energy are some examples of renewable fuel sources. There are also many things that people can do everyday to save energy (and, in turn, conserve fossil fuels).
Biomass gasification is a process by which biofuel is produced. It has been used for over 180 years but in the last decades it has been reconsidered as an interesting technique due to the fact that oil supplies are decreasing. As mentioned before, gasification is a thermal process. Heat is added up in order to convert the organic mass to biofuel. The biomass usually undergoes drying, pyrolysis, partial oxidation and reduction. Nowadays the configurations used for gasification are three: fixed bed gasifier, fluidized bed gasifier and entrained bed gasifiers. The simplest configuration is the
In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
The concept of this essay is to stress that biofuels are a viable and sustainable energy source than fossil fuels, showing its advantages but not ignoring its disadvantages which also enlightens us about the cleaner and renewable natural resources. Biofuels is an alternative source of energy which can end the global dependence on fossil fuels.

With the depletion of fossil fuel resources comes speculations and debates about alternative energy sources. The world, including the Philippines, is practically dependent on a dwindling non-renewable source of energy. Today, experts are debating about and considering three options: Nuclear, Solar, or Wind Energy. Everyone has been accustomed to the bad image of nuclear energy as a result of the Chernobyl and Fukushima incidents above all others. The popular belief is that radiation from a nuclear meltdown is very harmful to humans and other living things—which is true—and that nuclear power plants are very dangerous and not ideal—which is not. According to Smith, et. al (n.d), all the nuclear disasters that ever occurred were caused by human error and natural disasters like tsunamis, not one because of system failure. Putting the false beliefs aside, with proper engineering and adequate maintenance by experts, a nuclear power plant is a very ideal and viable source of energy for the following reasons:
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
