How important is it to explore alternative forms of energy? Energy is the source of life. Energy that we gain from food helps us to survive. It implies that food is a source of energy for us. The vehicles that we use‚ the industries that manufacture different products are all dependant on some kind of energy source. The source may be electricity or fossil fuel but it is clear that everything needs an energy source to run. In the old days firewood was the energy source. After the invention of automobiles

that I find majorly important are wind power‚ solar power‚ and hydropower. All three alternative energy sources could be very useful to use in the future‚ but they all also have negative sides to them and that is why all three‚ instead of just one‚ are the best to use in the future. One alternative source of energy that could be used in the future is wind power. It is a clean source of energy that does not put off any air‚ land‚ or water pollution. Wind power is a renewable energy‚ and can be substituted

materials for producing windmill turbine blades related to the life cycle assessment with sustainable perspective. So we made the problem formulation like this: How can bamboo fibers be used in the design and production of wind mill blades and how would it influence the impact of wind mill blades in a lifecycle perspective? In order to answer this question‚ we made a research about the properties of bamboo material and made a LCA to compare the performance between bamboo turbine blades and glass fiber

2012 Professor Sean Homer Research Paper Why renewable power sources are better than nuclear power? Nuclear power is the most productive power source. However‚ there are several ongoing debates around the efficiency and the usage of nuclear power. Several factors such as the catastrophes in Chernobyl and Fukushima and the depleting of coal and gas reserves have led to the idea behind the renewable power sources. The renewable power sources are the future of the energy production in the world

use more renewable forms of energy like that from the sun‚ wind or geothermal energy. For centuries‚ the wind has been used to sail ships and to pump water. Now it is used to produce electricity. Groups of wind turbines along the red sea in Egypt generate large amounts of electricity. Water is also a renewable form of energy. Huge quantities of water go through the high dam at Aswan from lake Nasser. This hydroelectric power supplies Egypt with a lot of its electricity. As well as being

Moreover‚ the growth of the economy means there are many more power stations being built and used‚ contributing again to the level of pollution – this just shows that there is a positive relationship between the consumption of energy and economic development. Due to rapid economic expansion‚ India has one of the world’s

Indonesia‚ it is not only a major issue‚ but also an urgent problem that needs to be resolved soon‚ otherwise Indonesia will be in very big trouble in the near future. It is true that the government has the program “10‚000 MW projects” for building a new power plant‚ but there are too many obstacles for it to be successful in the short term. The diagram shows the increase of Indonesia electrification ratio from 1980 to 2012. Electrification ratio is a measurement of the availability rate of electricity

Students will familiarize themselves with alternative fuels that can be used in vehicles by engaging in an introductory class discussion‚ reading and answering questions from the Reading Passage‚ working in groups to conduct Internet research on assigned topics

These are solar energy‚ wind energy‚ geothermal energy‚ hydroelectric energy‚ tidal energy‚ nuclear energy and biofuel. Solar energy Every year‚ the earth gets more than enough energy from the sun as much as 35‚000 times the total energy needs of man. One-third of this solar energy is either absorbed by the outer atmosphere or reflected back into space. Today‚ this form of energy is used in furnaces for homes and for heating swimming pools. Its major applications are in power plants‚ space ships

Starting on these premises‚ we proceed direct to the solutions through examples.
