Mecine meeting may 7, 2012

Bio-based economy – Alternative energy

Plans, Experiences and Considerations

Biobased economy = alternative energy- Covenant of Mayors Goals: 20 % CO2-reduction in the community

before 2020.

- Improvement of alternative solutions partly based on biomass

Focus

Power & heating: Strategy for heating and energysupply.

Buildings: Municipal buildings, schools, technique, lighting, industry, private and public houses.

Transport: Municipal fleet, public & private transport, mobility plan public/private - car/bicycle.

Planning: Strategic town planning, raising building density, transport and parking in the city, car out – bus + bicycle in.

Public involvement and cooperation: campaigns (shops, villages), green fund, local climate council.

Heating and Power

• 50 % of CO2 emission comes from heating of buildings

• Conversion of gas, oil and power to district heating,

• Implementation of biomass ‘fuel’ in district heating,

• Plans for solar cells/-heating, biogas/-mass and windmills.

• Potential in CO2-reduction 110.000 t pa (70%)

Electric bikes for commuting• 35 electric bicycles in action• 2 month testdrive by citizens –

total of 105 test drivers• Citizens were commuters by

car with a minimum of 5 km to work

• 73 % used the bicycle instead of car

• 40 % will buy an electric bicycle for themself

• Average mileage of 400 km pr. driver (42.000 km)

• Estimated reduction of 6 t CO2

Transport

Public involvement and cooperation

Energy Village Herringløse

• Village with 418 inhabitants/200 houses and without district heating or gas: Oil, electric & biomass heating, heatpumps (air, soil)

• Meetings with focus on alternative energy in local citizens defined organisation

• Work focus on:– Options for local district heating– Local heatproducers: Biogas, biomass, windmills, etc.– Citizen to citizen knowledge transfer (showroom at the neighbours)– Strengthening the collaboration between local professionals– Renovation af buildings with better insulaton– Common buying of electricity and insulation– Energy day in the village with craftsmen

Windpower

• Community plan for windpower 2013

• Windpower can support individual heatpumps in areas without waterbased distribution systems

• Or common heatpumps and common waterbased distribution systems

• Geotermi to be investigated

Solarcells

• Solarcells to be installed in municipal buildings (1,5 mill. Euro)

• Actual good incentives for private individual solar plants in family houses.

Biomass - Biogas

• Biomass to be used in combustionplants in connection with local district heating system

• Biogas challenge: Combination of suited biomaterials in sufficient amount within sustainable distance.

• Biogas used in local power/heating plant with district heating

• Biogas used in existing gaspipes for natural gas
