2. ENERGY

3. Definitions What is energy? Ability to do work What is Clean Energy? Is an energy supply whose utilization does not impair the environment and livelihoods but the magnitude differs, some are cleaner than others. What is Clean Energy? Is an energy supply whose utilization does not impair the environment and livelihoods but the magnitude differs, some are cleaner than others. What is renewable energy? What is renewable energy? Is the energy that comes from resources that are naturally replenished on a human timescale. Is the energy that comes from resources that are naturally replenished on a human timescale.Biomass,Solar,Hydro,Geothermal, wind wPOWER Hub - Wangari Maathai Institute

4. Some applications of energy Cooking Lighting Heating Farming wPOWER Hub - Wangari Maathai Institute

5. Why clean energy? Health: Around 14,000 people die annually in Kenya as a result of indoor air pollution (smoke) Climate change: Burning biomass as wood or charcoal releases green house gases such as carbon dioxide which causes global warming wPOWER Hub - Wangari Maathai Institute

6. Why renewable energy It can be replenished over the years Cost effective Minimal negative effects to the environment wPOWER Hub - Wangari Maathai Institute

7. Fire What is fire? What are the constituents of fire? – fire triangle What is fuel? wPOWER Hub - Wangari Maathai Institute

8. Fuels – cooking The main source is firewood This can be sourced sustainably from Forests Woodlots/On farm Agricultural wastes wPOWER Hub - Wangari Maathai Institute

9. Charcoal Production of charcoal(inefficient carbonization,cost) Use of charcoal with appropriate technologies Charcoal waste wPOWER Hub - Wangari Maathai Institute

10. Alternative fuels  Briquettes Made through compaction of biomass material in to a solid unit. The process can be manual or machine operated. A binder is added to make the biomass material stick to one unit. The binder can include starch, gum arabica, soil, animal dung, waste paper Bio mass material can be from rice husks, sugarcane bagasse, coconut husks, maize cobs, saw dust, charcoal dust etc. wPOWER Hub - Wangari Maathai Institute

11. Advantages Less emissions Easy to make Cheap High heating value wPOWER Hub - Wangari Maathai Institute

12.  Pellets Pellet fuels are fuels made from compressed organic matter, or, biomass wPOWER Hub - Wangari Maathai Institute

13.  Biogas This is a renewable energy source form waste that has decomposed. Materials used as organic matter include: Kitchen wastes, animal manure and slurry, agricultural residues, food and agro industries wastes, organic municipal wastes wPOWER Hub - Wangari Maathai Institute

14. Bio fuels – ethanol & bio diesel Energy derived from plant and animal materials. Examples of biofuels include; ethanol, biodiesel (vegetable oils and liquid animal fats) wPOWER Hub - Wangari Maathai Institute

15. Clean energy technologies Cookstoves Why have a Clean and modern cookstoves Saves more fuel Less toxic emissions Less cooking time & time to collect fuelwood Reduced greenhouse gas emissions More time for education and income generating activities wPOWER Hub - Wangari Maathai Institute

16. Traditional Stoves Improved Stoves and Fuels Advanced Super Clean Stoves and Fuels Technology shift wPOWER Hub - Wangari Maathai Institute

17. Lighting Sources of energy for lighting in domestic use Kerosene Electricity Candles Fire Solar wPOWER Hub - Wangari Maathai Institute

18. Use of kerosene for lighting Do you use kerosene for lighting? Health –indoor air pollution Cost Burns Not renewable wPOWER Hub - Wangari Maathai Institute

19. Solar lighting It is the Energy from the sun Can be used for cooking, lighting, running gadgets and electronics. Advantages Clean- no emissions Free - from a renewable source Cheaper Low maintenance cost wPOWER Hub - Wangari Maathai Institute
