Review of Related Literature Group 2 (IV-Assumption) Background information: (Local) Based on http://www. zamboanga. com, Caringo , Mercedes, Camarines Norte, Philippines is experiencing too many black outs, they also state that they don’t rely on Diesel fuel and coal for their Electricity, because in their place there are many renewable and sustainable source of energy like Hydro Power, Solar Power, and Wind Power.
Background information: (Foreign) According to http://www. bbc. co. uk Peru is also experiencing life without electricity as it is in Caringo,Merecedes,Camarines Norte, Philippines.It is stated that life is harder without electricity. Electric light especially is in most of need, because people cannot continue their activities after dark, this also affects the children in schools when reading or writing. Theories and data of existing problem According to (http://www. scientificamerican.
com/article. cfm? id=electricity-gap- developing-countries-energy-wood-charcoal) 130 years ago Thomas Edison had created an artificial light to be used for the humanities sake, but there is still one quarter of the world’s population or 1. 5 Billion people (mostly on Africa and SouthAsia) that lacks on electricity despite of other nations that is continuing to grow in terms of technology and electricity like USA and China. Because this nations that lack on electricity still don’t have access on modern fuels like natural gas, kerosene and etc. Instead they are using charcoal and woods that causes pollution and health problems. Researchers are recommending these Nations to switch to more efficient energy for their own health. Some of the people think that this 1. 5 billion people without electricity is a good thing because this will lessen the possibility releasing heat trapping gases that will soon cause Global Warming.
Subjects related to the problem: Electricity Generation (http://www. ge-flexibility. com/power-generation-basics/how- electricity-is-produced/index. html) Electricity is mostly generated by turbine generators. Mechanical Energy is converted to Electrical Energy from turbine generators through moving steam, water or gas across the blades of the turbine.
The turbine is connected to a metal rod in generators that turns the large magnet surrounded by coils of copper wire. The magnet creates a strong magnetic field that lines up with the electrons of copper coils that will soon cause them to move.This is called electricity Thick wires are used to carry the electric current from generators to transformer. When the electricity arrives on its destination it passes through transformers to minimize or to decrease its voltage levels. This is applicable on levels to 110-220 volts for safety use on our households Electricity enters a house from a meter that is measuring the amount of electricity the house is using through electricity control panels that controls the distribution of electricity to walls, lights and etc. Electricity http://global.

wikipedia. org/wiki/Bicycle A human powered single track vehicle with two wheels and is pedal powered.Recommendations: Bike powered electricity generators are not sustainable Basically it is because of its many proceeds and transformation of energy. Also due to the energy losses in the battery, the battery management system, other electronic parts, and the motor/generator. These energy losses add up quickly: 10 to 35 percent in the battery, 10 to 20 percent in the motor/generator and 5 to 15 percent in the converter The energy loss in the voltage regulator is about 25 percent. This means that the total energy loss in a pedal powered generator will be 42 to 67.
