  2. 2. What is RENEWABLE ENERGY? Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.  Renewable energy replaces conventional fuels in four distinct areas: electricity, generation, hot water/space heating, motors, fuels. 
  3. 3. Why is renewable energy important? Renewable energy is important because of the benefits it provides. The key benefits are:  Environmental Benefits  Energy for our children's children's children  Jobs and the Economy  Energy Security 
  4. 4. Types of renewable energy  There are 5 types of renewable energy sources: 1. wind power 2. solar power 3. geothermal energy 4. hydroelectric power 5. biomass
  5. 5. Biomass  Biomass is biological material derived from living, or recently living organisms. In the context of biomass for energy this is often used to mean plant based material, but biomass can equally apply to both animal and vegetable derived material.

  8. 8. Uses of Biomass in Pakistan  Biomass energy is derived form various sources which help in generating sufficient energy for use. The various source of generating energy from biomass are wood, waste, alcohol, garbage, landfill gases. Wood is either taken from trees or from the waste of industrial processes. The waste material of industry like paper making is really helpful in providing pulping liquor. The second major source of deriving biomass energy is from the solid waste. This solid waste is either provided by municipality waste or industrial waste. When energy is extracted either from alcohol or from the fiber present in the corn, it is termed as ethanol fuel. This ethanol fuel is really helpful in providing fuel to the cars and farm tractors.
  9. 9. Advantages of Biomass  Biomass is very abundant. It can be found on every square meter of the earth as seaweed, trees or dung.  It is easy to convert to a high energy portable fuel such as alcohol or gas.  It is cheap in contrast to the other energy sources.  Biomass production can often mean the restauration of waste land (e.g. deforested areas).  It may also use areas of unused agricultural land and provide jobs in rural communities.  If it is produced on a renewable basis using biomass energy does not result in a net cabon dioxide increase as plants absorb it when they grow.  It is very low in sulphur reducing the production of acid rain.
  10. 10. Potential Impacts of Biomass  The potential impacts of biomass energy development projects are discussed in this section in general terms on the basis of typical utility-scale biomass projects for which information is currently available. The impacts of a specific project will be determined by factors such as the type and size of the biomass facility, the amount of land disturbed by construction activities, the amount of land occupied by facilities long term, the location of the site with respect to other resources (e.g., species use of the site, distance to surface water bodies), and so forth. The various types of biomass facilities (such as power plants, ethanol ,production plants, bio diesel and biogas production plants, and landfills) may involve different activities and, as such, result in different impacts.
