3.3. Renewable energy

Aim: Solutions supporting the use of renewable energy sources are introduced. These can include, for example, mapping the potentiality of renewable energy, use of wind power, bio-energy, biomass and wood pellets, use of sludge for combined heat and power and biogas from organic materials, heat pumps, and use of geothermal heating.

Renewable energy and prosperity to Central Finland

Bioenergy covers the major part of energy consumption in Central Finland. Town centres have biomass based district heating and bigger towns and industries have CHP plants. A present campaign is to replace oil in the remaining smaller boilers with renewable biomass. In addition to benefiting the climate, the biomass operations have clear economic benefits to the area.
Asko Ojaniemi, Managing director of Energy office in the Centre of Finland

How to get to 100% renewable energy in the municipality of Thisted

More than 200 wind turbines, biomass fueled district heating plants, district cooling, wave energy plant in the North Sea, national center for large wind turbines, an energy plan for the municipality are some of the solutions that is used to reach the target in the municipality of Thisted.
Torben Juul-Olsen, Technical Director, Thisted Municipality, Denmark

Proactivity in new green development - case Lolland municipality

Metropolis will only be green cities in close corporation with there peripheral municipalities. This new symbioses can, in the next ten years, be the largest growth driver for peripheral areas regarding new jobs and avoiding migration. The municipality of Lolland - an island in Region Zealand with 1% of the Danish population, is already exporting five times more green electricity than it consumes. Lolland is also developed as a full scale laboratory for green energy within Wind-, Wave-, Hydrogen-, Smart Grid- and Biomass production. Being proactive in this new green development, Lolland Municipality expects more than 2000 direct jobs before 2020. Most peripheral municipalities can do the same.

Local Sustainable Energy Production

The presentation introduces a business model that integrates traffic, waste management, biogas production and agriculture in order to develop a sustainable transportation system. Sustainable transportation systems based on biogas production allow to make a decrease the levels of the CO2-emissions, the nitrogen emissions and the noise. Moreover, the particle emissions are non-existent. By producing and utilizing renewable fertilizer substances arising from biogas production, the waste handling is improved, the amount of job opportunities in the area increases and the dependency of imported fuels is minimized.

Thisted (DK), Lolland (DK) and the Region of Central Finland (FI) demonstrated their achievements as to renewable energy production positive development during past years. Åbo Academy (FI) presented the biogas utilization planning results as traffic fuel in Turku. The waste is ideal source energy and the residue of waste suitable as the fertilizer. The main energy sources were several; local wind power, geothermal energy, biomass like straw, solar, waste to energy and wood. The technologies like CHP and district cooling were used.
Lolland´s specialities are offshore wave and wind testing area, hydrogen generating with wind energy and delivering gas to household heating and algae for biogas. Both the Danish municipalities had started co-operative field testing utilities of wave and wind power by universities and companies.
The Region of Central Finland is using most renewable wood for energy purposes in Finland but there is also available the local energy source, peat critised often due to it`s non or slowly renewing origin. Anyway the recent growth in energy wood production has lead to 37% energy self- sufficiency and created hundreds local jobs and the future is promising.
The main findings were that good results can be achieved by number of methods and with many kinds of actors and through various activities. There are however challenges in fitting together different advantages and interests.

Discussion and conclusions

The lively discussion dealt with local information activities .The school is important channel like honest discussion with people. The wind power meets often local significant resistance; specially the big ones are difficult as NIMBY-matter (not in my backyard). The hydrogen causes fears due to its´s explosive nature. The wave energy areas were not so far resisted on but the fishing might be the one reason. Lolland was helped to proceed by the finance crisis.
The biomass helps and offers job and natural resource utilization in rural areas and farming. The available jobs earn and need locally much more important role. The public procurement is not enough developed in the cases of needs to proceed rapid. The energy business possibilities like selling electricity to grid can help the municipality financially. The municipality can work as promoter, starter and coordinator. Co-operation between private and public is essential.
