   • Burning biomass still causes pollution
   • Collection of fuel-wood can cause desertification
     • Burden on women and children to collect it
   • Growing plants for bio-fuels reduces space for crops
   • Million gallons of water used/day

4. Examples

   • 2020 - biomethane could supply 15% UK domestic gas supply
     • From sewage of Thames Water
   • Global production doubled '00-'05
   • Brazil leads in biomass production

5. Location Factors

   • Near biomass supply
   • Large space required
     • Power plant
     • Land for plants
       • Fuel vs. food contraversy
   • Local acceptance
   • Conditions for crop growth
