WHERE DOES ELECTRICITY FOR MY HOUSE COME FROM?? By Clare Jenkin
WELL, OUT WITH IT!! Usually, energy for a normal household is produced by burning fossil fuels such as; coal or natural gases and oils. Though, with recent study it shows that some day if we keep burning fossil fuels, pollution in cities and surrounding area’s will increase and we will someday run out of the fuels.
RENEWABLE ENERGY During the last few years people have discovered nature’s beauty’s can produce energy, this sort of power is called renewable energy. E.g. The sun’s rays can be used to generated energy to solar panels that produce electricity or wind turbines use the strength of the wind to turn the turbine. These renewable energy sources don’t produce any pollution like burning fossil fuels do.
MY HOUSE’S ELECTRICITY At my dad’s house we are installing solar panels. This will keep pollution down and after the installation of the solar panels the power bill should lessen by heaps. At mum’s she rents a house. The landlord hasn’t got any solar panels installed or has a wind turbine to power the house. So mum has to pay for electricity burnt from fossil fuels.
HYDRO ENERGY Hydro energy is produced by the power of moving water. Even many, many years ago people used the power of water. Wheat mills used the water to turn the turbine that grinds the grains. Here is a diagram:
In its simplest form, electricity is generated by rotating a magnet inside a wire coil. In a power station, this process is enhanced; the magnet is an electro-magnet or “rotor” spinning inside the fixed coils or “stator” of the generator. Each generator is mounted on a vertical shaft above the turbine and water is used to drive the turbine, which operates the generator. Transformers boost generated voltage to a level that can be economically transmitted over long distances by transmission lines to the towns and cities of eastern mainland Australia.
