Together with the rapid growth of the world population, the limited ability to supply of non-renewable leads to energy demand on a rise especially in developing countries. This situation results in the risk of depletion of cheap fossil energy and environmental pollution as well as climate change. According to Loir, there will probably be sufficient oil and gas for this century, and coal for 2 or more (Loir .N 2007, p.843). Or Edwin Cartlidge reports "the annual total consumption of energy...
Chemical contamination of Antarctic remains one of the most significant impacts of its fragile environment due to human occupation. Chemical contamination from land-based operation on average extends for kilometres (Kennicutt, 1992; 303) as witnessed in the largest oil spill to ever occur in Antarctica. This unfortunate incident occurred though the Bahia Paraiso region of Antarctica. It is evident that the levels of contamination can vary from terrestrial sources according to the seasons...
There are many different types of power sources across the world that produce electricity in many different ways. There are methods that use the power of nature, such as: hydroelectric power which uses the power of water to spin a turbine, windmills that use the power of the wind to spin a generator, and solar power which uses the heat from the sun. There are also man-made methods such as: power plants that burn coal, generators that burn gasoline, and plants that burn wood to use the heat from...
As the world's energy crisis progresses, renewable energy sources like tidal power are being explored. Tides, the rise and fall of sea levels, are created by changes in the gravitational forces of the sun and moon as well as the earth's rotation. Tidal Energy is generated by converting gravitational potential energy of high tides into hydroelectricity. Most ocean environments experience two high tides and two low tides [] everyday. There are three main ways to harness tidal energy,...
In the polar environment, there are beautiful polar animal in an section of the country in a polar environment, the polar animals you can see are like penguin, huskies, polar bears caribou musk ox, wolf, wolverine, arctic fox, ermine, lemming, arctic hare, arctic ground squirrel, birds, whales, harp seal, walrus, etc… In the icy land there are amazing large ice bergs surrounding the area. Did you know that you can see only one-fifth of the ice bergs above sea water? There are lots of...
The vulnerability to climate change is considered to be high in developing countries due to social, economic and environmental conditions that amplify susceptibility to negative impacts and contribute to low capacity to cope with and adapt to climate hazards. In addition, projected impacts of climate change generally are more adverse for low latitudes, where most developing countries are located, than for higher latitudes. The developing countries face many challenges - poverty, a high disease...
This assignment is an energy case study. The aim of the assignment is to learn, combine and manipulate the new and existing technologies and also the ethical issues behind the adoption of nuclear power in UK for the next thirty years. People should have new organizational behaviours to develop an organizational framework which meets the current ethical and environmental requirements, while remain innovative. I am acting as an independent energy consultant who is advising the UK Government. I am...
The inner core of the Earth is where geothermal energy can be derived. Favorable sites for geothermal energy extraction are rare. The location it occurs is at pushed up magma near the earth's surface through faults and cracks in the crust. The water that leaks in is heated by the resulting "hot spots" which is 2 to 3 km from the surface. Subsequently, hot water and the steam can be channeled directly to warm homes or to turn turbines. Lastly, cooler water runs back down while the hot...
The demand for good-quality drinking water is rapidly increasing world-wide. Increasing population, with the desire to improve standards of living, contribute to the increased demand. Increasing of potable water demands throughout the world has stressed traditional, high quality sources of potable water. Therefore, numerous potable water suppliers have restored to utilizing alternative water resources of lesser quality, such as ground waters, highly turbid and organic surface waters, and...
The use of biomass to generate electricity in thermal power plants has been practiced in many parts of the world for over 100 years. The use of high-pressure boilers to raise steam and to drive steam turbines is a well-proven and reliable technology. Over the years, these technologies have undergone many improvements. Today, the equipment to convert bio fuels into electricity is available at competitive prices. This equipment is very efficient and the pollutants emitted from them are minimal....
