RENEWABLE and NON-RENEWABLE:- Enviroment management

  1. 1. natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes. The term renewable resource also describes systems like sustainable agriculture and water resources. Sustainable development (SD) refers to a mode of human development
  2. 2. sun Solar energy is the most abundant and easily available renewable resource solar power including solar cookers, solar stills, solar water heating WIND Wind power is the conversion of wind energy into a useful form of energy. originally developed for milling grain for food production
  3. 3. HYDROPOWER energy derived from the movement of water in rivers and oceans hydroelectric power involves creating a dam, and using the resulting water force to turn a water turbine and generator GEOTHERMAL Geothermal energy comes from the Earth's crust
  4. 4. Pollutant free  Easily available Found across the globe  Never extinct
  5. 5. Very costly Harmful for wildlife Can’t be use all the time Requires vast land
  6. 6. Natural resource which cannot be reproduced, grown, generated, or used on a scale which can sustain its consumption rate. consumed much faster than nature can create them. Eventually fossil-based resources will become too costly to harvest and humanity will need to shift its reliance to other sources of energy. These resources are yet to be named.
  7. 7. COAL Formed from fossilized plants and consisting of carbon with various organic and some inorganic compounds Oil A carbon-based liquid formed from fossilized animals. Pipes are sunk down to the reservoirs to pump the oil out.
  8. 8. NUCLEAR Radioactive minerals such as uranium are mined. Electricity is generated from the energy. WOOD Obtained from felling trees, burned to generate heat and light.
  9. 9.  Used worldwide  Main sources of energy  Relatively cheap to extract  readily available
  10. 10.  gives off atmospheric pollutants  Only a limited supply.  Uneven distributed globally  costly to harvest
  11. 11. We should use the non-renewable resources very wisely and effectively. We should save them for future generation by giving ore focus on SUSTAINABLE DEVELOPMENT. Human beings have already started using alternate for limited resources. But these should be used all over the world.
