exploit wave power into useful form of electric energy. The WEC’s are attached to special turbines, buoys and other machineries that capture the power of waves and tides and combine them into pollution-free electricity (Aux 2010). The energy produced usually depends on the height of the wave, the speed of the wave, the wavelength and the density of water. The use of wave energy varies considerable

sense, the fossil fuels are a one-time gift that lifted us up from subsistence agriculture and should eventually lead us to a future based on renewable resources." Kenneth Deffeyes (2001) "I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." — Thomas Edison, 1931 We cannot create or destroy energy. We can only capture it. The sun provides either directly or indirectly nearly all of the energy available to

life today is consumed with at least one type of energy. Without the movement or conservation of energy no activity of any kind can take place. Energy has played an important role in early civilizations, starting with human power and animal power to the fossil fuels that power the world today. Everything that people now possess today has been influenced by energy. It has brought about culture, religion, and new technologies. All types of energy have limits on how much it can produce and when supplies

October 16, 2015 reflection paper 3: Shaping the future of solar power (Solyndra) After reading the case on “Shaping the future of solar power: climate change, industrial policy and free trade” I gained much clearer insight to the history and working of the solar energy industry. From personal experience, I have seen the recent increased use renewable energy, particularly wind and solar energy. Internationally, in Europe wind and solar energy as source of energy is not new revelation too me

time, the use of petroleum has caused a lot of trouble. Most wars after World War II happened in the Middle East because of oil, and for this reason alone,-- I think oil is a thing that causes and has caused the most serious trouble among humans in history. Now, the whole world’s population relies on oil deeply. Since the industrial revolution of the nineteenth century, it is hard to imagine how our lives would be possible without fossil fuel energy, especially oil. Nearly every machine we use

Introduction of accident Following a major earthquake, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident on 11 March 2011. (http://www.world-nuclear.org/info/fukushima_accident_inf129.html) What is radiation and how it damage people. Radiation may be defined as energy traveling through space. Non-ionizing radiation is essential to life, but excessive exposures will cause tissue damage. All forms of ionizing radiation have

have made the switch to solar or wind energy, thinking that as long as they don’t use fossil fuels they are doing the environment a favor. However, no matter the energy source for use on a large scale, it is going to have its own unique issues. There are a number of energy alternatives within the United States. The two sides to the argument are renewables, such as wind and solar energy (the two most popular) versus fossil fuels, such as coal and natural gas. Wind turbines can kill birds, cause

extreme weather. Hurricanes are a major hazard to buildings, people, and the environment. A hurricane has killed more people than any other storm there is. In order for a tropical storm to be classified as a hurricane its wind speed has to reach 74mph but usually reaches higher wind speed than that. Some examples of hurricanes over the last couple of years are hurricane Ivan and Katrina. Hurricane Ivan made its appearance on the gulf shores of Alabama. This hurricane started at 2:10am Thursday September
