Biomass is a biological material derived from living, or recently living organisms. In the context of biomass for energy this is often used to mean plant based materials, but biomass can equally apply to both animal and vegetable derived material. Biomass is considered to be one of the key renewable resources of the future at both small and large scale levels. It already supplies fourteen percent of the world’s primary energy consumption. Growing Biomass is a rural, labor-intensive activity, and can, therefore, create jobs in rural areas and help stem rural to urban migration. Biomass is carbon based and can be composed of different mixtures of organic materials such as, Hydrogen, oxygen, nitrogen, and also small quantities of other atoms, which are mainly metals. For plants, carbon used from biomass is absorbed from the atmosphere as carbon dioxide using energy collected from the sun, during their process of photosynthesis. Plants may be eaten by animals and is then converted into animal biomass. If plant material is not eaten it is generally either broken down by some microorganisms, or burned, such as fossil fuels (coal, oil, and gas), which comes from biologic material. But remember there is a difference between the two, because biomass is not fossilized material (Like oil, coal, and gas) but fresh material that can grow again after being harvested. Today biomass is used to produce power and heat in large-scale facilities: solid biomass, biogas, biofuel, or biodiesel. Biogas is a gaseous fuel, made when methane, produced by the fermentation of organic matter. Biofuel is fuel derived directly from living matter, and biodiesel is a biofuel intended as a substitute for diesel.

... wood as a source of heat, or Denmark where a plant burns twenty eight thousand tons of straw to produce 13 megawatts of electricity. Mega Watts are a unit of power equal to on million watts. Which is a lot compared to the product of pollution in Denver. That’s 13 million watts of power…that could possibly be used for a better circumstance!!! Although, this is a great way to generate biomass into electricity…it also pollutes many of the surrounding areas. Every year 335,000 Americans die of lung cancer, which is a direct result of air pollution. The average adult consumes 3,000 gallons of polluted air every day, and as we all know pollution is a major problem in environment today. But if we want to continue to have more electricity, etc., we should use biomass instead, because it is a lot healthier, than any of the other alternate energy resources, used still today!
As stated earlier, the burning of fossil fuels to produce energy is one of the largest contributors to global warming. This non-environmentally friendly energy source has to be replaced in order to keep the world going. There is a type of energy source that seems easy to create and doesn’t require radical changes: Biofuels. Biofuels are a greener version of diesel and oil. They are any solid, liquid, or gas fuels produced from organic matter; the range of organic materials used for biofuel production includes plants such as corn, sugar cane, soy, and wheat; vegetable oils and animal fats; ...
Our energy needs have significantly changed since the first Industrial Revolution that took place in the period from about 1760 to sometime between 1820 and 1840. Before this time period, our energy needs were modest. For heat, people relied on the energy of the sun, but when it failed them, they burned wood, straw and dried dung. For transportation horses and the power of the wind was used in sails. For agricultural work animals were used to do the jobs that could not be done with man labor. By harnessing the power of steam and wind simple machines could be run to grind our grain and pump our water. The Second Industrial Revolution, also called the Technological Revolution is considered to have begun around the time of the introduction of the Bessemer steel in the 1860s. This technological Revolution is considered as the second phase of the Industrial Revolution that resulted in factory electrification, mass production, the creation of production lines and the development of machine tools. With the appearance of the low cost automobile and the wide spread of electricity our society's energy needs have changed forever. Since the modest beginning of the oil industry in the mid 19th century, petroleum has risen to global dominance leading to mass consumption as the primary fuel to generate electricity, heat, to power our homes, cars and to support economic growth. Unfortunately, as a consequence of industrialization, atmospheric CO2 levels started to rise in proportion to the usage of fossil fuels. This trend raises some concerns about the well being of our environment, and researchers around the world started to look for alternative, cle...
Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least, set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in. America is wasting their finite resources, such as coal and nuclear, when we could actually be using renewable sources that will never run out. Most of our country’s citizens have never thought about where their energy comes from, or they do not even care.
The main points I presented included whether or not to utilize alternative sources, such as: Geothermal, biofuels, or solar. Another stance on the topic is to remain using generic fossil fuels, such as coal and oil. The common ground would be to use both alternative sources and traditional fuels to sustain efficiency. There are multiple benefits to alternative sources. Benefits of biofuels include the fact that they can come from a variety of sources, such as plant materials, crops, and recycled vegetable oils, as per Christopher Cone of Science Progress stated. Another source is biodiesel, which replaces standard diesel. If utilized, it can reduce greenhouse gas emissions, secure energy supplies, and promote the standardization of renewable energy. More positives of alternative sources suggest possible tax exempts, lower costs overall, coming from domestic sources, and also the availability of blending with multiple sources at a time. Possible negatives include the disadvantage of being limited or refined by OEM companies (Original Equipment Manufacturers) and scarcity of refueling options. The Environmental Defense Fund suggests, “using alternative sources, as traditional fossil fuels are known to cause health concerns…” (EDF). These health concerns include toxic compounds attacking organs, causing brain damage, or possible death. In parts of the country where lakes and waterways have been contaminated with mercury from
“The fuel is produced in a thermal/mechanical processor called a biomass fractionator. In a matter of minutes, the fractionator converts biomass like crop residues, algae, soft wood chips and rapid growth crops like switchgrass into multiple gas streams and into biochar. The gas can be upgraded to gasoline In a one-step catalytic conversion process.” (Rocke 1). The idea of this fuel source is also very cheap. It runs for about $1.50 per gallon. Finally, the use of Biochar can be shipped at in gallon tanks very easily. Aside from the cost and shipping efficiency, ‘According to one prominent study (Woolf et al, 2010), sustainable biochar implementation could offset a maximum of 12% of anthropogenic GHG emissions on an annual basis. Over the course of 100 years, this amounts to a total of roughly 130 petagrams (106 metric tons) of CO2-equivalents. The study assessed the maximum sustainable technical potential utilizing globally available biomass from agriculture and forestry. The study assumed no land clearance or conversion from food to biomass-crops (though some dedicated biomass-crop production on degraded, abandoned agricultural soils was included), no utilization of industrially treated waste biomass, and biomass extraction rates that would not result in soil erosion” (International Biochar Initiative
Today our renewable fuel of the future is ethanol. Many of us know ethanol as E85 or other higher levels of ethanol blends. Ethanol is a renewable fuel made from various plant materials known as biomass. Ethanol is non-toxic and biodegradable. Ethanol is a clear, colorless liquid primarily made from corn,sugar or cellulosic feedstocks.The potential benefits of cellulosic feedstock is that it results in lower levels of greenhouse gases emissions into the atmosphere. Cellulosic ethanol use could reduce greenhouse gases by as much as 86 percent. In the United States, ethanol is mostly made up of corn grain. Ethanol is not meant for a fuel substitute but a fuel additive. Of gasoline
...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 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.
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
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).
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.
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:
For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
Fuels like coal, and oil that once were a fine innovation in creating energy are now rapidly deleting and one day will be gone forever; energy that won’t last is often referred to as non-renewable energy. Besides being set up to fail and become inefficient in the future, fossil fuel energy is not clean to use and poses several environmental complications. Coal, for instance is “the dirtiest of all fossil fuels. Coal combustion not only produces sulfur oxides and nitrogen oxides that contribute to acid rain and snow, it generates millions of tons of particulates that cause asthma and other respiratory diseases.” As with all usage of fossil fuels, it creates enormous amounts of carbon dioxide, which contributes to greenhouse gas. Not only are fossil fuels dirty, they also pose as a security risk and unforgiving on the American wallet. (Saini)
