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.…

Renewable energy is energy from natural resources such as sunlight, wind, rain, tides, and geothermal heat, these resources are naturally replenished. Renewable energy does not harm the environment or deplete any of our natural resources like fossil fuel. Renewable energy is not subject to sharp price changes because it comes from natural resources. Biomass is currently the largest U.S. renewable energy source with more than two hundred existing bio power plants providing energy for one point five million American homes, according to renewable energy specialist Davor Habjanec. The first time I heard the political differences about renewable energy was the last presidential debate. President Obama stated that he has and will continue to invest in renewable energy, like windmills and solar power. His opponent, Mitt Romney accused Obama of not using more fossil fuels found in America, from building a pipeline in Alaska to investing in oil and natural gas. Romney also claimed that the Obama administration was not expanding research of renewable energy. President Obama’s economic stimulus package included a number of incentives like thirty percent tax credit for renewable energy.…
The first contribution for sustainable environment by new technology is helping people to explore sources of renewable energy. This means that with the help of new technology, people can make full use of natural sources to create green and renewable energy that people cannot image nor realize before. Such as tidal power, wave power, solar power, wind power and so on. According to Jamie Frater (2009), “These sources of energy provide an alternate ‘cleaner’ source of energy, helping to negate the effects of certain forms of pollution. All of these power generation techniques can be described as renewable since they are not depleting any resources to create the energy.” For instance, the wind power, people set wind turbines to transform wind energy into electricity or mechanical energy. In the process of creating energy, there is no consumption of resources. It…
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.…
The rapid depletion of fossil fuels has given serious warning that the era of using conventional energy is coming to an end. Due to the energy shortage, a need to find replacement of fossil fuels has appeared. Moreover, problems such as various pollution and serious climate change have occurred, which makes renewable and less pollution energy source alternative choices. Therefore, three options can be suggested to solve the problem with the depletion of natural sources. These options could be wind power, geothermal energy and solar power, which will replace fossil fuels in the future. This essay will evaluate these there renewable energy sources by using the following criteria: availability, cost, practicality, and environmentally friendlness.…
It’s no secret that fossil fuels are rapidly depleting. What is not so well known is that Generation Y (my generation) is going to be around to see it. That is why immediate action to incorporation renewable energy sources is crucial. Specifically, the government should stop giving subsidies to oil companies and instead be using taxpayers’ money to develop solar energy, such as, solar thermal energy in order to establish a sustainable, clean, responsible and efficient form for energy for generations to come. While solar energy startup and even maintenance costs can be just as expensive as oil and coal production, solar energy is undoubtedly worth the price in the long run, even solely for the benefit of CO2 reduction. As far as using solar thermal energy locally, my hometown of Bloomington, Indiana currently uses solar thermal energy for various residential and commercial uses, but there is much room for expansion. Finally, I am a firm believer that helping the world consequently helps us in return and I believe that eventually, tax payers’ dollars could even be used to install solar energy devices in LDCs to ultimately better the world we all live in.…
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…

The energy generated from wind is clean and efficient. The wind energy industry helps to ensure that electric demands are met, the wildlife impact is minimal, the environment is not devastated, as well as creates new jobs during the construction of the wind farms, daily operations, manufacturing components and exporting components to foreign countries. The use of energy has been a key in the development of the human society by helping it to control and adapt to the environment. Managing the use of energy is inevitable in any functional society. The trend is the same in any other field of social activity, be it construction of social infrastructure. Production and consumption of energy resources is very important to the global economy.…
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.…
Hydropower is a renewable source of power used throughout the world. It uses the force of water to generate power sustainably. A big concrete wall is built in a fast flowing river and water builds up behind it all the while the pressure is building up. As the energy level rises to a maximum, the water is released and as the fast moving water passes through turbines which then convert the waters energy into power. It works when water I channeled into water turbines. The force of the moving water, makes the turbine blades move and powers an electrical generator, which converts the power into energy. Hydropower is the most efficient and advanced way of making renewable power and is used in more than 170 countries worldwide. Hydropower is renewable because after the water has made its way through the hydropower station in continues downstream to the sea. At sea level it evaporates because of the heat. It then rises up through the atmosphere and turns into clouds as the air cools. The clouds then rise which causes more condensation, which then results rain. The rain then falls into the rivers again where the cycle begins again.…
How many times have you walked by a penny on the ground, not bothering to pick it up? One cent on the sidewalk doesn¡¦t seem worth much, but the one-cent premium per kilowatt-hour for green energy somehow seems like too high of a cost for little gain. This is a continuing issue with the green energy movement: how do you get consumers to pay a premium for green energy? APS is facing this problem, and our solution is eGreen, a campaign to tie APS to green energy and motivate customers to ¡§go green.¡¨…
