The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

Bottled Water Proposal In recent times‚ one of the world’s favorite grab and go drinks has come into question whether it is safe enough to drink or not and that is bottled water. “In 2007‚ according to the BMC‚ the total spending on bottled water in the United States reached an estimated $12 billion‚ despite the availability of clean and inexpensive tap water”(Lee‚Warhol). Some people argue that bottled water is not only unsafe for us‚ but also for our environment and it is much more expensive

Two of which are of great interest to architects are Active Solar’ and Wind Technology.’ I believe that architects have a responsibility to look for new sources of energy‚ not just for our environments sake but to gradually lose our dependency on fossil fuels which is quickly running out while demand keeps increasing. This research paper is about the

Another thing it pointed out was just how many contaminants are found in bottled water. There are many hazardous things in the bottles that people drink from everyday and most of us don’t realize how dangerous this is to us. It also pointed out the damage that these bottles have on the environment after they are thrown away. Bottled water is quickly

First of all‚ we know that the sun and wind energy are the most advance alternative energy. Today‚ mankind are beginning to look for energy that will support their life for the next century. So I could not think other than sun and wind energy as the best alternative energy resources‚ however it still needs a lot of development. The sun radiates vast amount of energy‚ which nourishes all life on earth and is the driving force behind the planets weather patterns and other natural cycles. In order

The use of nuclear energy should be banned as evidenced by the number of accidents‚ health effects‚ and global impact. Countless nuclear power plant accidents have been occurring quite frequently since its invention. Some accidents have even been underestimated‚ because the nuclear industry does not want the people to know about how dangerous it is. For example‚ the Three Mile Island Accident

Water Filtration There is a wide range of filtration methods currently being used all over the world. Some can be dangerous to handle and very reactive while others can be used in an any day household. Although no filtration method is perfect‚ combining different forms of filtration can provide near-perfect water. One note to take is that most of the time the more that is filtered‚ the pricier the method is. Three very effective methods of water filtration are “Ion Exchange”‚ UV light‚ and

Energy is constantly being produced and used‚ with the introduction of renewable energy it has allowed society to be more aware of the impact and effects of how energy is generated. Energy does have a predictable effect on a range of themes that have been intertwined‚ for example‚ the push towards renewable energy is caused by societal pressure and is only pursued by politicians if the type of energy is economically valuable. Energy is deeply rooted within society‚ government and the economy there

Water and me Water is a colourless‚ transparent and odourless liquid which forms the seas‚ lakes‚ rivers‚ and rain and is the basis of the fluids of living organisms. It is a chemical compound whose formula is H2O. It covers 71% of the earth’s surface and is necessary for every known organism to live. 97% of the total water found on the earth lies in the oceans. The rest of water is in the form of glaciers and ice caps (2.1%)‚ ground water (0.6%)‚ inland water (0.2%) and water vapours (0.001%).
