Solar power emanates from the conversation of energy from the sun, into electric energy. Engineers can use photovoltaic, or concentrated solar power energy. Photovoltaic is a process that converts directly sunlight energy, to electric energy (Sussman, 2012). The use of solar power technology is an indirect process of converting sunlight energy, to electric energy. Photovoltaic uses the photo electric effect to directly convert sunlight into electric energy. It uses solar cells to produce...
In a recent paper published in The Lancet it was proclaimed that "climate change is the biggest global health threat in the 21st century" (Costello et al. 2009). There have been a number of wide ranging hypotheses and models produced attempting to predict future changes in the climate but due to its non-specific nature these predictions often conflict with each other thus giving an inaccurate portrayal of all climate models. Nonetheless it seems that the general opinion is that...
The project deals with Integrated Coastal Zone Management (ICZM) and tries to understand it's value by studying various case studies. The project can be divided into five sections. The first section deals with basics of ICZM, framework and implementation of ICZM. The second part deals with understanding ICZM implementation in context of a developed country which in our case is Germany. The third part deals with ICZM implementation in context of a developing country which happens to be...

In the past decade, Victoria, along with the rest of Australia has experienced a number of factors leading to the increase supply and demand of fresh water. Drought is seen as the major cause of Victoria's fresh water demand. 2006 showed some of the many long term effects of drought starting to appear across the country namely the state of Victoria. Australia's state governments all took action accordingly with different methods of compensating for water demand and future demand, with the...
A recurring theme in the debates that encircle waste and resources management is the extent to that the reprocessing and recycling of materials proposals genuine benefits to the environment. Often, criticizers of the strategy drive towards larger recycling assert that the deed of recycling could in fact possess slight or no benefit to the environment, counselling that extra power and energy could be utilized in bringing in materials to the recycling ability than is saved by the procedure of...

Water reuse refers to making beneficial use of diverse sources such as reclaimed water or treated water rather than fresh drinking water supply for specific purposes such as irrigation, industrial or environmental uses (Water recycling in AU, 2004). Direct potable reuse refers to the water which is conveyed directly from treatment plant to the water supply system is highly treated and suitable for drinking water use (Water recycling in AU, 2004). Indirect potable reuse refers to the water which...
In this report you will read to find out things about infrared waves. Infrared waves were discovered in the early 19th century by an astronomer. It is part of the electromagnetic spectrum, between microwaves and visible light. Infrared radiation is widely used in many different aspects of life such as in remote controls, heating food and in night vision. Infrared waves can detect differences in temperatures and portray them in colors. Read on to find out more interesting facts about Infrared...
