Renewable Energies in your region
further green growth
A fair partnership between towns and
rural areas is needed

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 crude oil prices
Prices of heating oil 2008 to 2012 (Germany)

Energy costs increase
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%

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 on
central fossil fuels:
 80 % of the money leaves the region.
•
Energy concept based on
decentral 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.
Biogas plant in Mauenheim (Germany)

Example bioenergy village Mauenheim
•
Heat supply 90 % renewable.
•
Electricity supply 920 % renewable.
 900 % bioenergy, 20% solar.
 820 % export of electricity!
