Finding Alternative energy sources is a significant issue from all over the world. In contemporary society‚ due to the lack of fossil fuels and environmental problems like air pollution‚ alternative sources of energy have being utilized widely for different domestic and industrial applications. Biogas is one of the alternative energy which instead of fossil fuels. This essay will focus on how to harness biogas effectively and it will highlight biogas as an important alternative energy plays

incineration of waste within the Sun (Touran). Although it may seem that nuclear energy isn’t safe for the environment‚ it is exponentially cleaner than current fossil fuels. By 2013‚ it has on average prevented 64 gigatonnes of CO2-equivalent greenhouse gas and 1.84 million air pollution-related deaths (Hansen and Pushker). With the replacement of fossil fuels as an energy source‚ this number can only

cars and do most of our tasks. Fossil Fuel is a non-renewable energy source. It results from the decomposition of dead and buried organisms. They are millions of years old and are fossilized under rock and sand. They are efficient energy producers‚ however‚ they also produce carbon dioxide‚ a pollutant. Their energy is released through combustion where heat starts an exothermic reaction. The hydrogen and carbon molecules react chemically to produce heat. Fossil fuels like natural gas can be used

Nuclear power is one of the latest ways to make energy. Although it is non-renewable it provides 6.3% of the world’s energy and 15% of the world’s electricity. It is designed to extract energy from the nucleus of a Uranium atom. Unlike fossil fuels‚ nuclear power doesn’t give off any greenhouse gases but produces radioactive and nuclear waste. France‚ Japan‚ and the United States of America generated 56.5% of nuclear power. In 2007‚ there were 439 nuclear power reactors operating around

Fossil fuels such as gasoline‚ methane and propane contain mostly carbon. When these fuels are burned‚ they react with oxygen and produce carbon dioxide. Because of our heavy use of fossil fuels‚ the amount of carbon dioxide in the atmosphere has been increasing since the industrial revolution. The destruction of forests which use carbon dioxide also contributes to the increase in carbon dioxide. Most of the light energy from the sun is emitted in wavelengths shorter than 4‚000 nanometers (.000004

climate change‚ nuclear energy is considered the key future energy resolution. In favor of greater reliance on nuclear energy‚ Mark Lynas – a climate-science author strongly brought in the reasons of: 1st‚ nuclear power avoiding climate change while fossil fuels have failed to do so and green energy capability is still being questioned; 2nd‚ opponents overstating danger even after many reactors has been safety improved; 3rd‚ the cost is acceptable comparing to other renewables energy. In contrast‚ Peter

energy source. The source may be electricity or fossil fuel but it is clear that everything needs an energy source to run. In the old days firewood was the energy source. After the invention of automobiles and airplanes in early 20th century‚ fossil fuels have been the most prominent source of energy. Fossil fuels fulfill most of the energy requirement of the world because of which energy produced from other sources are regarded as alternative energy. Fossil fuels are found in a limited amount which puts

but the former takes a more natural‚ less energy intensive path‚ while the latter takes more energy input from the use of fossil fuels to power the machines to plant‚ sow and maintain the tree farms. Once the trees are felled‚ requiring energy input‚ it is converted to pulp. The transformation of tree chips into pulp and then paper is an energy intensive endeavor‚ taking fossil fuel inputs to form and shape the paper into a specific product.
