Renewable Energies in your region further green growth

-A fair partnership between towns and

rural areas is needed

Sheffield, May 10th 2012 Jörg Dürr-Pucher

Think globally – act regionally

• Climate Change is an urgent global topic.

• From G 20 over Europe to Great Britain,in Counties, towns and villages many people and politicians have realized the need of climate protection.

• All future activities and measures have to be:

Concrete

Common

Local und regional

Green growth needs active regions

People, municipalities, politicians, enterprises, craftsmen, banks and regional governments can form alliances for:

•Saving energy,

•Improving energy efficiency,

•Investing in renewable energy,

•Combining heat and power,

•Harmonizing supply and demand of power.

Green growth needs governmental support

Governments on european, and national level have to support renewable energies by:

•Feed in tariffs,

•Taxes on greenhouse gases,

•Funding programmes for renewables,

•Pro active regional planning.

•Organizing regional investment vehicles.

Ecologic drivers for renewable energies

• Climate change.

• Clean air, water and soil.

• Over use of natural resources.

• Beauty of the landscape.

Economic drivers for renewable energies

• Strong increase of prices for fossil fuels.

• High fluctuation of fossil energy prices.

• Decrease of costs for renewable energy, especially solar energy.

• Possibility of establishing regional economic power and influence in a more globalized world.

• More jobs and added value in the city or region.

Development of price indexes in Germany

between 2007 and 2012:

• General inflation: 1,8 % per year

• Woodchips: 7,1 % per year

• Oilprice: 11,22 % per year

District heating price mix: 70% woodchips / 30% inflation

Heating Oil 100%

Energy costs increase

Costs of heating oil and district heating

Jörg Dürr-Pucher 15

Motivation for joining district heating

• Rise of crude oil price.

• Old heating systems.

• Energy savings.

• Costs of chimney sweeper.

• Combination possibilities with other renewable energy sources (solar heat, stove).

• Climate protection.

Energy future for rural areas and cities

• Renewable energy belts surround towns.

• Investment in renewable energy production.

• Jobs and green growth for the region.

• Save energy and improve energy productivity.

• Export of green products and services.

Vision energy belt

• Potential of renewable energy production in rural areas is higher than the consumption.

• Much space, low population density, only some industry.

• First aim: 100 percent renewables in rural regions.

• Second aim: energy export to towns.

Vision Energy belts

Main challenges:

• Reconciliation between rural areas – towns.

• Energy transport to the towns.

• Energy storage.

• Smart grid.

Flow of resources and energy vs. money

• Energy concept based oncentral fossil fuels:

80 % of the money leaves the region.

• Energy concept based ondecentral renewable sources:

80 % of the money circulates in the region.

Investment, jobs and added value

• Construction of windmills or small windparks.

• Installation of geothermal heating.

• Production of renewable energy sources from forests or farmland.

• Reduction of energy demand by new heating systems, new windows and better insulation of buildings.

• Lighthouse investments in public buildings.

Investment, jobs and added value

• Construction of biogas plants, using waste biomass or farmed biomass.

• Installation of wooden biomass heating systems (pellets, woodchips, split logs).

• Use of industrial heat.

• Installation of photovoltaic und solarheat plants.

• Bioenergy villages and district heating systems in cities.

• Energy belts for towns.

Project financing

• Communal investment.

• Famer found a coporation.

• Founding of an energy cooperative.

Bioenergy village Mauenheim

• Biogas plant (500 kw) produces 4 millions kwh power and 3 millions kwh heat.

• Wooden biomass heating system (900kw) produces additional heat in winter and as reserve.

• 4 kilometers distict heating supplies 75 (of 105) households and two municipal buildings.

• Additional installation of private photovoltaic modules and solarheat.

Example bioenergy village Mauenheim

• Heat supply 90 % renewable.

• Electricity supply 920 % renewable.

900 % bioenergy, 20% solar.

820 % export of electricity!
