In recent decades, there has been an increased need to produce sufficient renewable energy to support global population growth. In response, it has become crucial to find socially responsible sustainable energy resources that offer energy security, reduce greenhouse gas (GHG) emissions, and do not compromise biodiversity or sustainability of existing resources. Despite efforts to reduce the amount of waste produced, a continually growing population limits the space available in landfills. Municipal and industrial waste biomass is often rich in organic matter, allowing for the creation and use of biofuels as an energy source. This organic matter can be used to synthesize ethanol, methanol, and biodiesel through the conversion of inorganic compounds into energy-producing organic carbon compounds. Moreover, unlike fossil fuels, which take millions of years to form, these organic carbon compounds are formed relatively quickly. Biofuel production from waste is beneficial as it allows for better management of landfill sites, and energy production from materials which typically cannot be recycled or composted. Most importantly, it allows for the reduction of significant amounts of methane produced from landfill gas emissions.…

1767, First Solar Collector In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven, reaching temperatures of 230 degrees fahrenheit.…
The use of alternative energy sources versus the use of traditional energy sources has become one of the country’s, if not the world’s, most heated debate in recent years. For the purposes of this paper, the term “alternative energy” refers to any form of energy that is not derived from fossil fuels. Alternative energy sources like wind farms, solar cells, hydroelectric dams, biomass fuels, and nuclear power have been considered to be attainable sources that will be able to sustain the global population’s high demands. Traditional energy sources like oil, gas and coal are what the modern world knows and is most comfortable with, as its established fountain of fuel. Weighing the benefits and drawbacks of one power source over another is a complicated process. There are many factors to consider, including everything from understanding the environmental effects of a particular type of power production and consumption, to addressing the power needs of the people and finding methods for delivering the power. Looking at both sides of this issue and surmising which argument seems to hold more water will allow for a reasonable conclusion to be made in favor of one side versus the other.…
Wind Energy, energy contained in the force of the winds blowing across the earth’s surface. When harnessed, wind energy can be converted into mechanical energy for performing work such as pumping water, grinding grain, and milling lumber. By connecting a spinning rotor (an assembly of blades attached to a hub) to an electric generator, modern wind turbines convert wind energy, which turns the rotor, into electrical energy.…
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3% and are growing very rapidly. The share of renewables in electricity generation is around 19%, with 16% of global electricity coming from hydroelectricity and 3% from new renewables.…
In today’s civilization the need for energy is increasing at a sky-scraping rate. Every object requires energy to function. This is where preserving energy happens to be a vital subject. To begin with, let me identify what energy is. Energy is the rate of doing work and falls into categories such as light, heat, work, etc. In today’s society there are two main sources used known as renewable and non-renewable sources Non-renewable sources are the sources that cannot be rehabilitated after an interval of time and then develops into petroleum, fossil fuels, natural gas, etc. These sources pollute the environment with dangerous gases as well as the atmosphere. These sources are clean and non- polluting of dangerous gases keeping it to a minimal considerable amount. These sources can never be exhausted and called non-conventional sources of energy. Renewable sources consist of solar energy, bio-mass, wind speed, etc (Why Renewable Energy). The idea of this research paper is to cover the latest in the field of renewable energy sources. This subject illustrates the diverse form of renewable sources of energy and their functions.…
Everything has two faces. Though the hydroelectric has a lot of advantages, for its low cost and low pollution, still it has some disadvantages. In some Asian countries, like Philippines and China, people can see the hydroelectric production clearly by year. There are some hydroelectric stations which are typical in these countries. Like the Bela in Philippines and the Three Gorges Dam in China. What’s more, we can also know something about the development of hydroelectric in these…
Energy conservation is important for each of us and our future generations. At the rate of consumption we can experience an energy shortage like never before. If we continue to deplete the resources that are available to us then it will affect us in many ways such as; forced rationing, increased cost, and restrictions on use. Now is the time to seriously look at alternative energy sources before it’s too late. For Industrialized nations, it is necessary to have reliable sources of energy. Energy is used for many things including; heating, cooking, transportation and manufacturing. Energy can be put into to categories, renewable and non-renewable. In this paper I will layout the differences between renewable energy and non-renewable energy, methods of energy conservation in our homes and communities, and finally economic impact of changing.…
After experiencing the replacement of manual and animal labour by steam engines in the Industrial Revolution, cheap fossil fuels then became the main source of energy. However, faced with the notable increase demand for energy, fossil fuel, as a non-renewable resource becomes scarcer and more expensive nowadays. To solve this problem, the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more secure. Renewable energy is such a potential energy. This essay will give an outline of three sources of renewable energy to be used in developing nations, which are solar energy, wind power and biomass. First, it will give a definition of fossil fuel and renewable energy, then it will move to analyse these three sources, evaluating them in three criteria: technology, cost and reliability to see whether they have great potential helping the developing world moving upwards in the future development.…

Past achievements were considerable; still there is a wide window of opportunities to further promote clean and renewable energy technologies so that the country can better realize its full potential. Renewable energy currently makes up only a small percentage of the total electricity mixes in the country. Advanced clean fossil-fuel based technology is left largely unexplored despite the continued significance of fossil fuels in Thailand. It…
Description: The Indian solar energy sector has been growing rapidly, in the past few years, majorly due to Government’s initiatives such as tax exemptions and subsidies. Due to technical potential of 5,000 trillion kWh per year and minimum operating cost, Solar Power is considered the best suited energy source for India. Today the Solar power, has an installed capacity of 9.84 MW which is about less than 0.1 percent of the total installed renewable energy of India’s~ currently total installed renewable energy stands at 13,242.41 MW as per MNRE. India's power sector has a total installed capacity of approximately 1,46,753 Megawatt (MW) of which 54% is coal-based, 25% hydro, 8% is renewable’s and the balance is the gas and nuclear-based. Power shortages are estimated at about 11% of total energy and 15% of peak capacity requirements which is likely to increase in the coming years. The cost of production range is Rs 15 to Rs 20 per unit for the solar energy, which is very high when compared to, Rs 2 to Rs 5 per unit for other conventional sources in India. Much of the country does not have an electrical grid, so solar power will indeed be a boon for water pumping, to begin replacing India's four to five million diesel powered water pumps, each consuming about 3.5 kilowatt of off-grid lighting. Solar energy technology consists of solar thermal technologies, which utilize sun’s energy and solar photovoltaic technology, which convert solar energy directly into electricity. According to the 11th five year plan, the government of India projects a massive expansion in installed solar capacity, and aims to reduce the price of electricity generated from solar energy, to match that from fossil fuels like coal and diesel by 2030. MNRE has set up target to add 14500 MW by 2012, from new and renewable energy resources out of…
Energy sources play a crucial role, affecting just about every activity that societies do in every country around the globe. The role in the economic development of a region or country does not need emphasis; because of the greater effects, it exercises a huge influence. It is the key element in the production process, and the lack or shortage of it has a serious impact on the economy. Energy is produced from a variety of different sources such as the wind, water, sun and even plants. The United States Government and other governmental entities such as the Department of Energy, provide funding for the research and development of alternative energy and innovations. “…President Obama announced that DOE will hand out a total of $3.4 billion to 100 utilities and other energy companies to spur modernization of the US electricity grid” (Kramer, 2009). This research paper argues the possibility of perhaps, the lack of federal funding availability, or the abundance of federal funding via government grants for the research of alternative energy. It also argues the impact on the country’s population and its economy. The paper will discuss the different sources of federal funding for the research of alternative energy such as the Energy Efficiency and Conservation Block Grant Program and the Federal Energy Management Program.…
