Alternatively, saving resources

Friend all surely know, the energy we use in everyday life certainly becoming more and more reduced, may experience shortages may even run out without rest. Examples of electrical energy. If the user is not saved or replaced by using alternative energy from now, what you want someday our world into darkness because there was no electricity? Sure you want to do .... ga Well, to prevent it, firstly it is needed awareness of our own self. Next, we need to consider alternate energy from this very moment.Some examples of alternative energy sources that have been used in the world to become electrical energy, among others:1. THE SUNDid you know? Our country is located in the vicinity of the equator and tropical climate is perfect to use alternative energy sun. If you belong to upper class families, it is better you try to use a roof made of solar system, known as photovoltaic cells. The price is not cheap, to the roof with a standard size to reach USD 200 million. But with this roof system, certainly very can reduce electric bills, let alone with a system like the current bills. So that your family can save electricity bill later.2. WINDWind energy is already quite widely used by humans. Kinetic wind power is used as a wind player using wind turbines for both at home and for business purposes. One turbine can feed electricity to 30 houses you know .. Pretty much it .. Currently in Indonesia, alternative energy wind is still under development and experiment. Wind energy is converted into electrical energy by such a converter, which is planned to be installed in every home residents to accommodate the energy gain from the wind. Electrical energy is produced and then sold to the local PLN. So that the people would not spend the cost of buying electricity but instead to get additional revenue by selling energy gain in their homes - each. Very helpful right?3. NUCLEARWith uranium fuel, metals found in rocks and processed in a nuclear reactor produces heat energy which will be used as an ingredient to turn turbines that exist. These energy sources do not release greenhouse gas emissions. 20% of electrical energy sources in the United States has used nuclear energy.
