...It is important to conserve energy especially when it is produced by non-renewable resources. We use non-renewable fuels to crank our cars, to hear our homes and to cool our homes. When pollutants from these non-renewable fuels are released into the air it contaminate the air we breathe along with the water that we drink. With that being said it is important to conserve energy to keep the air that we breathe cleaner. Conserving energy is also important because it reduces the electric bill and the gas bill which in turns save you money. Using renewable resources are the better ways to conserve energy and to maintain a healthier atmosphere for all humans, plants, and animals. There are two types of energy resources and they are renewable and non-renewable resources. There are three top renewable resources and they are but not limited to solar energy, wind energy and hydropower. Solar energy comes directly and indirectly from the sun which contributes to the growth of plants and trees. Wind energy is the movement of air when warm air descends and cooler air comes in. This type of energy is beneficial for sailboats. Hydropower comes directly from the energy of flowing water which make electricity. All of these renewable resources come directly from the earth. Non-renewable resources are coal, petroleum, natural gas, and nuclear energy. These resources come from underground and most of them derive from the fossil of dead plants and animals. This resources are not reusable which...

...A Sustainable Development Stacy Hohn-Sosa DeVry University Sustainable Development “Go Green” is a slogan that is pushed on society with the intention to bring awareness to sustainability. In Michael Pollan’s The Omnivore’s Dilemma, the issue of agriculture sustainability is presented. True sustainability is not just agriculture; it is all the natural renewable resources available in the world. Humans do not realized the amount of packaged products they consume in a day or the harmful chemicals that we pollute the earth with when we drive or apply them to agriculture. As consumers we look for convenient, cheap, and accessibility to minimize the time needed in order to perform everyday tasks. Until humanity grasps how these every day products are hazardous not only chemically but also on our natural resources; we as a people will continue to consume un-renewable resources. By increasing the concept of a sustainable development, humanity will use fewer nonrenewable resources such as petroleum’s and fossil fuels and rely on renewable resources such as solar energy. Without a defined structure of true sustainability; governments, corporations, businesses, companies and individuals will continue to depreciate the Earth’s natural resources until it is uninhabitable. “All definitions of sustainable development require that we see the world as a system—a system that connects space; and a system that connects time.”(EurActiv, 2004) Sustainability as...

...edu David NEWLANDS Senior Assistant Professor International School of Management ~ IESEG, Lille, France d.newlands@ieseg.fr Abstract As the new millennium evolves, many further and higher education establishments are bracing themselves against externally imposed challenges. Emerging fiscal constraints are reducing public funding for public institutions in various countries including the United States, United Kingdom and France. USCA for example saw state appropriations reduce from $11.1M in 2008 to $6.1M in 2011. Rising costs of energy in part due to under-capacity to store during off-peak seasons and infrastructure overhaul project investments compound budgetary decision making. Reducing energy consumption requirements partially can alleviate the funding shortfall. Environmentally friendly solutions that reduce dependence on, or usage of fossil fuels, can contribute to reducing the destruction of, or help clean, our world. This solution reduces costs and simultaneously provides attractive incentives to exert intensive efforts...

...source of unlimited, sustainable, renewable energy, it is no wonder why solar energy systems is being used worldwide from country’s in poverty to homeowners in the United States. From large scale utility plants to urban communities, more solar energy systems are being used to generate electricity for many different reasons. Whether it’s saving our planet, saving money, or increasing the value of a home, these are just a few reasons why solar energy is growing. Over the past three decades SunPower Corporation has been able to improve the technology in renewable energy to generate the most energy from the sun. SunPower has been leading the quest to improve lives and our world for a better future one day at a time. According to the U.S. Energy Information Administration in September of 2014, utility-scale solar power plants generated over 12,303 gigawatts- hours of electricity compared to September 2013which generated 6,048 gigawatts-hours. This is enough energy to power 1,513,703 average U.S. homes, (Danko, 2014). With the trend of solar energy and clean carbon emissions, the numbers of solar companies has risen. From manufacturing to installing, having a solar energy system has been easier and cost effective especially for homeowners. To motivate homeowners to start using solar energy system, local and state wide government has offered many incentives such as, “the eight-year extension of the Investment Tax Credit for renewable energy that was part of the 2008 Bush economic...

...is a serious danger to the Earth. The Intergovernmental Panel on Climate Change (IPCC) has stated that the consensus of scientific opinion is that Earth's climate is being affected by human activities (Oreskes, 2004). The United States and China are responsible for the most global carbon emissions, accounting for 40 percent (McKibben, 2012). Arising from the production and consumption of goods and services; a lot of greenhouse gas emissions are created through agriculture. With large pushes to “Go Green”, many companies have made strides in changing their process of production, types of products, and promotions due to the influence of the public, and the necessity to reduce their carbon footprint. Global warming has become a danger that cannot be overlooked like it has in the past several years. It is an exponentially growing problem, with very few things being done to prevent and reduce problems. ‘Planet Earth’s average temperature has risen just under 0.8 degrees Celsius with current reports which has led to some damage to our environment. About 400,000 square miles of Artic ice has melted. The sea level has risen 10-20 centimeters over the past one hundred years’ (McKibben, 2012). Extreme weather patterns have been recorded over the past decades such as fires, flooding, hurricanes, and other natural disasters. These have been present and increasing over the past years with obvious damages and changes...

...Solar Photovoltaic System: An Alternate Source of Energy Introduction Despite enormous hydropower potential (theoretically 83,000 MW), only about 40 percent of the population of Nepal has access to electricity and this percentage even drops down in the remote areas. Since the rural energy demand is basically for lighting, Government of Nepal (GoN) has its dedicated energy policy to promote Renewable Energy Technologies (RETs) including Solar Home Systems (SHS) which follows the principles of Solar Photovoltaic Systems. Photovoltaic are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons. Solar cells produce direct current electricity from sun light, which can be used to power equipment or to recharge a battery. The first practical application of photovoltaic was to power orbiting satellites and other spacecraft, but today the majority of photovoltaic modules are used for grid connected power generation. Due to the growing demand for renewable energy sources, the manufacture of solar cells and photovoltaic arrays has advanced dramatically in recent years. Solar photovoltaic is growing rapidly from a small base to a total global capacity of 40 GW (40,000 MW) at the end of 2010. More than 100 countries use solar PV. Some 24 GW of solar was projected in November 2011 to be installed in that year, pushing...

...Kavethkar Green energy is the need of the hour to sustain our energy requirements. Green energy includes natural energetic processes that can be harnessed with little pollution. Anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar energy, biomass power, tidal power, wave power, and some forms of nuclear power (ones which are able to "burn" nuclear waste through a process known as nuclear transmutation, such as an Integral Fast Reactor, and therefore belong in the "Green Energy" category). Some definitions may also include power derived from the incineration of waste. In this report we have discussed on various dimension of non renewable energy resources and its impact on our environment. It is aptly said that “The Earth has enough to satisfy the Need but not the Greed of the Humans” We have gone beyond boundaries, now if we look back the results of our greed is appalling for us. The below sections show the various examples of non renewable energy sector- Electricity Sector in India The electricity sector in India had an installed capacity of 250.256 was of end July 2014. Out of which considerable amount, approx. 69.12% (172.986 GW), is generated from non-renewable energy source.

...going up, it is time to start thinking about, “How can we make residential high-rises more sustainable in Toronto?” in terms of energy conservation and efficiency. If this significant problem is overlooked it could cause serious issues with our city, our ecosystems could be wiped out completely, our air and water could be entirely con-taminated, and it could diminish our natural resources. It affects more than just the residents whom live in the buildings, it affects the developers/builders, the residents of neighbouring buildings, even the kids that play in the park across the street. This paper will look at the problem and some possible solutions in terms of using renewable energy sources to sustain residential high-rises. Methods including Geothermal energy to heat and cool the building, Green-roofs that can be used to grow plants/food and can gather rain water, Cistern tank to catch all the rainwater that can then be used to wash clothes and flush toilets and possibly also for irrigation purposes if need be, Wind energy to provide electricity, as well as Solar energy to provide electricity can all be used to minimize a building’s ecological footprint. Geothermal energy is literally the heat from the earth, energy obtained from the hot areas under the earth’s surface. Geothermal energy is becoming very popular in Canada, taking the natural energy from the earth to heat and...

...life. There are three types of green technology. There is green energy, green transportation, and green building. Pollution must be diminished to moderate global warming. The encouraged use of green technology may increase the healthiness of the Planet. Green energy is renewable energy source, unlike fossil fuels. Even though green technology appears unaffordable, it is more efficient and lessens greenhouse gasses. Energy is extremely essential to everyday life. Individuals use energy to warm the home, keep the lights on, and the groceries refrigerated. Solar power is another energy source. There are currently one-hundred and sixty-five customer-owned solar electric systems in Madison, Wisconsin (Green Power Tomorrow, 2013) The expense for the installation of solar power for the home in Dane County, Wisconsin is thirty-thousand dollars. The cost-effectiveness of solar power depends on the following; how much sunlight one receives, where one lives, electricity usage, and the size of the solar system. (Chua, 2006) Solar panels are an excellent way to acquire the suns energy to deliver one with energy. Solar panels consist of a series of photovoltaic cells connected together. When the sun heats up these cells, it stores the charged energy into batteries. This is what helps people to power their homes. In 2007, the City of Madison, Wisconsin was named one of 25 Solar America Cities by the U.S. Department of Energy. Since receiving this designation, the City of Madison Solar...
