Statements
• The flowing energy on global level is 1000 times the today demand
• Locally produced bio energy is cheaper than • Locally produced bio energy is cheaper than any fossil fuels
• Burning bio fuel is more fun than fossil fuels
• Existing energy actors are not taking necessary actions
The Ineffective energy system
Reach the goals by utilising the losses
• The today primary energy consumption will be decreased by utilising the losses
• The losses can only be utilised for low temperature demandstemperature demands
• Low temperature demands is space heating, drying and evaporation
• Heat distribution system is the key
• District heating must be built in Europe as infrastructure

Latvia opportunities
• Large amount of district heating
• Large amount of farming land per person
• Natural gas dominating fuel today• Natural gas dominating fuel today
• No use of burnable waste today, only landfill
• Big part of district heating not used for CHP

Socio-economic benefits of using bio energy
• Land owners get long term contracts for energy supply and takes part in the local cooperation
• Uses the waste products from society as fertilizer
• Solves nitrogen leakage to recipient• Solves nitrogen leakage to recipient
• Clean farming land from heavy metals
• Local energy needs society planning
• Local energy needs local interests/owners
Rindi business model
• Feasability study together with local or regional authorities
• Find the optimum solution for the region • Find the optimum solution for the region
