...Introduction Around 77 percent of the electricity used by South Africa comes from coal produced electricity (Statistics South Africa, 2009). South Africa ranks in the top twenty countries in the world in carbon dioxide emissions. As a result, South Africa has set out to lower its greenhouse emissions and push for renewable energy. There are many paths to take in reaching this goal, but I believe South Africa should adopt a similar program as Germany’s Community Wind Power program in order to meet some of its renewable energy goals and needs and solve some of its infrastructure and economic issues. Background of South African Energy Eskom is South Africa’s national power utility, which generates about 95 percent of the electricity in South Africa (U.S. Commercial Service, 2012). Of the total electricity generated in South Africa, 88 percent comes from coal fired power, 6.5 percent comes from a nuclear station, and 2.3 percent comes from hydroelectric and pumped storage schemes (U.S. Commercial Service, 2012). Also, South Africa is crucial to the rest of Africa’s infrastructure, supplying two thirds of Africa’s electricity. In addition to being so crucial to Africa’s infrastructure, South Africa is one of the cheapest electricity producers in the world. The 2009 world economic crisis reduced South Africa’s power supply constraints, but this reduction didn’t last long. In 2010, the electricity demand in the country began to rise again with no sign of slowing down or declining...

...Sustainable Design Case Study on Fashion designer, Stella McCartney. • Stella McCartney would always touch on an element of a sustainable or eco collection in everything she did. • In her lingerie collection, she had a part of the collection that was organic, or with her Adidas collaboration again there were organic materials or recycled materials in the bags or shoes, and every part of her design at some stage comes into contact with that. • She wanted to isolate the collection and in itself make it completely sustainable .She stated she wanted to bring all those elements together and show the importance that it had within the brand. • The designer felt using conventional dyes was an efficient use of resources and had damaging consequences. Though she had to resort to using them in some of her collections she felt it was important to create high quality products for the consumer and not lose its desirability yet also try to be responsible in thinking how to source materials. • She usually sourced organic fabrics. • Some challenges she did face were playing by the rules and being limited. There were less colours, fabrics and different quality attributes she wasn't used to. • She agreed that "80 per cent of a product’s environmental impact is decided at the design stage". • She refrains from using fur or leather in her designs and she exemplified in the reason in the quote, "In the fashion world I think that most designers know fur is wrong. More and more of them also know about...

...new generation of wind power turbines is being considered at this very same site and the surrounding area. Although this newly proposed wind farm along six miles of ridgeline is estimated to produce 50 megawatts of electricity and provide enough power for 15,000 households, this project will result in the irreversible destruction of this mountain top ecosystem. The environmental costs greatly outweigh any financial benefits that this proposed project offers. Background In early 2007 a renewable energy company named Noble power, a company that specialized in wind turbine construction, met with local officials to float the idea of a wind park on the Pittsford ridgeline known as Grandpa’s Knob. Noble ran into financial problems as a result of the 2008 recession and was forced to close its Rutland office in January 2009.Another event happened in 2008 when Vermont set a goal of having 25% its energy needs met by renewables by the year 2025. One year later, Reunion Power, a renewable energy company based in Manchester VT, bought out nobles’ stake in the project and erected two meteorological towers and began gathering data on wind speeds. At the time there was some excitement about this project, as reflected in a statement made by West Rutland Town...

...Go Green Go Green 2012 Jeremy Nicholl HUM 111 3/18/2012 2012 Jeremy Nicholl HUM 111 3/18/2012 Go Green I believe Green technology is very important as we proceed in the clean-up process of our planet and as we explore alternatives for fossil fuels. Drilling for oil within our country may seem easier and less expensive, however it is a short term solution; we must not rely or assume that fossil fuels are an unlimited resource. We must consider alternatives for fuel and energy while recognizing the effects of pollution on the ozone layer. As we explore different types of renewable energy resources, we must be sure that they are safe on the environment and safe to use in homes or automobiles. Another aspect to consider is the availability of the resource. We do not want to waste time exploring resources which are not going to be readily available or resources that will diminish. The need for fossil fuels in the near future is still a necessity until a transformation can be made to an alternative source. There will always be a demand for fossil fuels, the goal is to reduce to use of fossil fuels as the burning of these fuels emits pollution into our atmosphere. The advantages of fossil fuels are that they are already readily available and distributed worldwide, which is very convenient. You can get gasoline and oil at any gas station and even some grocery stores, across the entire United States. Another advantage...

...II. Contemporary Energy Use Frederic Menz, a professor of Economics and Finance at Clarkson University, analyzed the impact of renewable energy policies and the relative adoption of those types of energies. He notes that at one time, conventional wisdom suggested that renewable energy sources would gain primacy due to the “rising costs for fossil fuels, growing concern about environmental issues, and national security concerns with imported oil” (Menz, 2005). However, the reality has been “virtually constant” production of electricity from renewable sources, with “coal and nuclear responsible for about two-thirds of net electricity generation in the United States for the last several decades” (Menz, 2005). As regards adoption of solar photovoltaic technology, some argue that its deployment has been tailored towards “a conglomeration of regional markets and special applications” for which significant production will remain elusive until standardized practices of connecting it to existing grid technology are established (Shum & Watanabe, 2007). The stunted deployment of renewable energy technology and failure to meet expectations for growth to surpass fossil fuels, are argued to be due to conventional fuel subsidies that “actively discourage consumers from seeking cleaner alternatives, encourage the overconsumption of resources… and lead to capacity development and consumer patterns in excess of true needs” (Sovacool, 2009). With significant conventional fuel subsidies intact...

...Reynolds. Earthship Biotecture is a method of architecture and design that incorporates recycled materials, earthen materials, and renewable energy sources into a sustainable and self-sufficient home. The purpose of this according to Michael Reynolds it to achieve energy independence, sustainable housing, and relieve the burdens of stress on the environment from conventional building methods while keeping cost minimal. Utilizing waste and earthen materials, Michael was able to construct comfortable living, beautiful architectural design, and self-sufficiency with sustainable technologies. In achieving low cost construction methods, as little as $20 a square foot, a new way of living can be imagined in which utilities, mortgages, and sustenance cost are reduced. This reduction in expenses provide for the availability of greater opportunities due to decreased economic constraints, but furthermore provides a cost effective and sustainable method for supplying homes for those stricken with poverty. The purpose of this writing is to discus some of the materials and methods required and the various components that work together to create a dynamic self-sufficient home. The first concept discussed is the principle of thermal mass to maintain a constant temperature. Houses are built with south facing walls, typically glass, providing the energy from the sun required to heat the dense walls. These walls begin to emit heat once temperatures drop. During the summer time a combination...

Disadvantages 4. Conclusion Wind Energy 3 Introduction In light of concern owing to depletion of fossil based fuels it is emerging that wind energy is receiving considerable thought as a solution to the looming energy crisis. The Australian Cooperative Research Centre (CRC) for Renewable Energy (ACRE) was established in July 1996 with a goal of undertaking research on issues of power generation, storage and conditioning, energy efficiency, system integration and policy analysis (Smith 2008). The goal of the Australian government to attain a renewable energy target of 2% by the year 2010 caused a dramatic interest in wind energy within the country (Paulson 2001). Advantages With the current focus on global climate issues wind energy has been found to be very advantageous as it is produced naturally (Wagner & Mathur 2009). The process of production involves manipulation of a naturally available resource (wind power) and thus does not pollute the air. It is known that power plant rely on combustion of fossil fuels and thus pollute the environment. Turbines do not produce any pollutants (Wagner & Mathur 2009). Another advantage with wind energy is that unlike fossil fuels which are geographically isolated to specific regions, wind energy is available in almost all regions of the world (Wagner...

...Enviroment Management We know that the most important thing we can do to reduce our impact on the environment is to improve our products’ environmental performance. That’s why we design them to use less material, ship with smaller packaging, be free of many toxic substances, and be as energy efficient and recyclable as possible. So as we continue to grow faster than the rest of the industry, we’re doing it with products that are friendlier to the environment than ever, and we remain committed to creating products that have the least amount of impact on the environment. Though our revenue has grown, our greenhouse gas emissions per dollar of revenue have decreased by 21.5 percent since 2008. And we’re still the only company in our industry whose entire product line not only meets but exceeds the strict energy guidelines of the ENERGY STAR specification. Environmentally conscious materials. In addition to eliminating toxins and designing products with highly recyclable aluminum enclosures, Apple works with environmentally conscious materials including recycled plastics, recycled paper, biopolymers, and vegetable-based inks. We have also found ways to reengineer secondary materials to the high standard of our designs. For example, our fan assemblies in Mac Pro use advanced materials derived from repolymerized plastic bottles. Speaker assemblies and internal brackets in the Apple Thunderbolt Display are made from recycled PC-ABS. In 2012, our latest achievements included the...

...2. Energy Sources and Consumption Level a) Fossil Fuel: Oil, Nature Gas and Coal Oil China is the second largest oil consumer and oil importer in the world.(EIA,2013) The demand of oil is driven by the rapidly growing economic and the large population. Oil consumption is also influenced by Chinese government’s energy polices, national oil companies and oil imports. In order to perform more efficiently the Chinese government has improved their policymaking and implementation capacity. Nation oil companies dominate the production of China’s oil. They also do oversea acquisition to meet the increasing demand of oil and develop more qualified technicians. China’s oil imports are increasing over years. It predicted that China will become the largest oil importers by 2013. Most of China’s oil fields are located onshore. They are more mature and the productions are approaching the peak of capacity. Now, China is more concentrated on developing fields which are located in new western interior provinces and offshore. Nature Gas The consumption of nature gas is rising very fast. In 2007, China became to be a net import of nature gas since the Chinese government promoted the consumption of nature gas to reduce the pollution from the use of coal.(EIA,2013) The major source of natural gas are from southwest of country and offshore fields such as Yellow Sea and South China Sea. Government encourages to developing more fields, pipelines and advanced technology to satisfy the rapidly...
