How can alternative sources of energy be harnessed effectively?
Biogas has been found to be a sustainable source of energy which is creates less emissions compared to coal and oil (1). Due to everyday needs and wants of the growing populations of the world, natural resources have been used and over used to a point where they are no more as available, such as fossil fuels in Kristianstad(2). This unfortunately creates concern for the future however, an alternative source of energy has been found and is being implemented in the Swedish city so that the strain on the over use of natural resources can be relieved(3). Biogas is produced from biomass and it is the best sustainable plan as a source of energy and a way to be more environmentally conscious(4).
In Kristianstad, Sweden - fossil fuels were used for up to twenty years before it was replaced by biogas. The city relied mainly on fossil fuels to generate heat for its homes and businesses. Fossil fuels were a reliable source of energy but it cost too much for the continent and the use of it was taxed by the European Union’s carbon trading system so a new solution had to be developed. This solution was the use of biogas, which is created by burning waste materials such as potato peels, manure, used cooking oil, stale cookies and pig intestines to generate heat and electricity or is refined as fuel for cars. Biogas uses such materials that would otherwise decompose in farm fields or massive landfills that wouldn’t create any benefits. Biogas also helps towards the fight against global warming because it eliminates the biological waste that would otherwise cause air pollution and water pollution in the environment. Due to Kristianstad’s change to biogas for a source of ene...

.... Biogas contain gas impurities that are corrosive to the internal parts of combustion engines which means that the maintenance costs for the engines would increase if there is continuous production of biogas, this corrosion also is induced in combustion engines such as car engines and boilers. Biogas plants also need high energy and heat; so some of the produced biogas needs to be used on site to meet the demands of production.
Biogas has replaced other sources of energy that could not be harnessed as well as biogas. Since the discovery of this sustainable source there has been a decrease on impacts from some countries on global warming as well as improvements in economies. It is and will continue to be the most sustainable source for energy as long as there are waste products to use, however the search for other sustainable sources should still be identified.
Biodiesel is considered an environmentally friendly alternative because it reduces the amount many toxic substances. Plants such as soybeans require carbon dioxide from the air to produce their stems, roots and leaves. During biodiesel production from soybean oil, carbon dioxide is produced and released in the atmosphere. Carbon dioxide is considered a green house gas (GHG). However, this cycle of GHG emission does not neccersarily contribute to the atmospheric carbon dioxide levels. This is because the next soybean crop will reuse the carbon dioxide emitted for its growth. Another important environmental benefit is that biodiesel reduces particulate matter (PM), hydrocarbon (HC) and carbon monoxide (CO) emissions. These benefits occur because biodiesel contains 11% oxygen by weight. Oxygen allows the fuel to burn better, resulting in fewer emissions from unburned fuel. And lastly, biodiesel fuels do not contain any sulfur and does not have an unpleasant smell when it is emitted from vehicles.
From the home to factories, families and industries are reliant on the use of nonrenewable fossil fuels to feed the needs of the everyday human. Fossil fuels are the main source of energy over clean, renewable sources such as the use of wind, solar energy, and water to power our homes, schools, and industries. In fact, about 85% of energy use comes from fossils fuels. The main reason being that using fossil fuels is cheaper than wind and solar energy. “For nearly two centuries, fossil fuels have been the cheapest source of energy” and widely abundant (Marburger, A global framework: international aspects of climate change). However, overtime fossil fuels will disappear due to the lack of time to replenish itself with the human races rapid use of it. Despite its current status of availability, there are many controversial issue in using fossil fuels; the most prominent issue being that it is the cause of rapid climate
Secondly, the use of biofuels is not a cost effective option as they are more expensive than fossil fuels. According to the County Commissions of the US Department of Agriculture and North Dakota State University, there are around seven biodiesel producers in the US. Biodiesel is the mix of biofuel and diesel in 20:80 ratio, which means that the cost of biodiesel will be around 20$ more ...
This research is purely to single out those factors that have caused a dramatic change in our environment and to find out how far does the excessive use of fuel will affect the globe that we are living in. I believe that the usage of transportation is not the only cause of these catastrophes, rather the usage of harmful fuels and the way we use it and the technology that assists in the breaking down of these fuels into energy all matters. This research will explore into how the adverse effects of extensive fuel usage could be reduced while researching into alternative energy resources.
Fossil fuel plays leading role in upsetting environmental and climatic protection. Our earth is at catastrophic risk by the exploitation of fossil fuels. Therefore, Pressure is on to find viable alternatives for energy to save bring a clean revolution. In that case, Bio-fuels make an attractive alternative for energy than fossil fuels. Various provocative questions need discussion that what are the attractive differences between both the fuels, why fossil fuel dependence are to be actually minimized? Why Biofuel magnetizes the environmentalists and people as viable substitute to fossil fuels? What is the scope of Bio-fuel for safer world in upcoming years? Above all, It will be conferred that why Biofuel is better than fossil fuels.
Woodfuel is not a new form of fuel; historically wood has been used as fuel for millennia with many civilisations relying on it as a source of energy. Even today the global south still use wood to produce heat. At the turn of the 19th century wood in the UK was no longer the main source of energy, but instead fossil fuel, which now outlines and dominates the way we live today. Furthermore with a growing population since World War II, much of the UK agricultural land has been used for conservation schemes and agricultural harvest only. Nevertheless with the rising concern of climate change, woodlands are now emerging to be used again for the use of renewable energy. Woodfuel in the UK is available as sawdust, pellets, sheets, charcoal chips, and firewood. The particular type used depends upon factors such as application, quality, quantity and source. When we view the geography of woodfuel in the UK we can view it from a broader perspective that reflects the discipline of geography. Sustainability is a way which tries to combine earth landscapes, environments and people together. We view sustainability “through the so called ‘three pillars’, namely economic, social and environmental or ecological” (Gregory et al 2009: 738) and it is these pillars which are to “be used as a benchmark for goals in which we must achieve” (O’ Riordan 2004: 245) so that we can use todays resources without compromising future generations supplies. Due to greater awareness of climate change and the need to use low carbon, renewable source of energy, this essay will predominately focus on the sustainability of woodfuel in the UK.
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.
Among various options available for bio-energy, bio-diesel, bio-ethanol and biomass gasification are three major options, which have huge potential in India to develop as energy sources and where investments made would be economical. The objective of this Business Plan is to review the option of electricity generation through the use of biomass energy.
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
...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.
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
Solid biofuels include manure, wood or charcoal burned as fuel as well as more recent innovations like high-density clean burning pellets. Solid biomass can be burned to produce electricity or heat either as part of a co-firing power plant or by itself. The most important advantages of biomass fuel is that it is most of the time got by waste-product of other processes, product or residue, such as farming, animal husbandry and forestry. In theory this suggests there's no competition between food production and fuel, although this can be not continually the case.
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.
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.
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)
