  2. 2.   There are many ways we can generate energy , the 2 methods under pinning these forms are renewable and non-renewable  Non-renewable – use fuel sources that do not replenish themselves quickly, like coal and natural gas  Renewable – use fuel sources that are readily available and inexhaustible or can be replenished quickly, like solar eaergy Energy generation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  3. 3.   Non-renewable forms of energy  Natural gas  Nuclear  Coal  Oil Energy generation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  4. 4.  Renewable forms of energy.  Solar thermal – energy from the sun to heat water  Solar photovoltaic – energy from the sun to produce DC electricity  Wind – wind energy to rotate wind turbines to produce electrical energy  Wave – wave energy to produce electricity  Tidal – the movements of the tides at sea to rotate turbines under the water surface to produce electrical energy Energy generation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  5. 5. Renewable forms of energy.  Biomass – burning of plant material and animal waste to produce heat energy  Biofuels – burning of bio oil crops to produce heat energy  Ground and air source – extraction of heat from the ground and air to produce heat energy (solar process)  Geothermal – extraction of heat from deep underground to produce heat energy (nuclear fission process)  Microgeneration using a water source – utilisation of a small source of water, like a stream, to turn a turbine to produce electrical energy Energy generation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM

  11. 11.   On average a mast mounted wind turbine would produce 2.5 kw to 6kw  On average a roof mounted wind turbine would produce 1kw to 2kw  When producing energy from domestic installations it is known as Micro-generation Micro-wind PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  12. 12. Rainwater harvesting This can save a householder large amounts of water. Storage cisterns are installed below ground and collect rain water from gullies. Average size may be 5,000 litres. Energy generation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  13. 13. Grey water recycling This system collects waste water from washing appliances like baths, showers and washing machines. It is commonly used to flush foul appliances like WCs. back-flow prevention is necessary to prevent any contamination of water supply PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  14. 14. Advantages of grey water recycling • Can lead to a reduction in water consumption without changing consumer behaviour • • Easy to install and maintenance free • Removes the need for complex water treatment • Can lower sewage costs • Can reduce ground water usage for irrigation • Less water will enter a city’s sewage systems – saves building new, or extending old, treatment plants PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
