As the first city in the world will Frederikshavn in 2015 have shifted their energy to be based on 100% renewable energy. The most remarkable is perhaps that Frederikshavn also include transportation in this calculation.The idea for Energy city Frederikshavn was born at Energy Camp 2006, where Denmark's leading experts in the energy sector came together to inspire each other to innovate in making Denmark a leader in renewable energy. Frederikshavn was selected because it is a city of a certain size (around 25,000 inhabitants) and the city should show that it was possible to convert the energy to 100% renewable energy in a few years. In year 2009 24% of the energy supply in Frederikshavn comes from renewable energy, but in 2010 it will be 40%. To achieve the 100% in year 2015 Frederikshavn will focus on several different sources of energy that can complement each other.
The energy sources are: waste, manure, straw, wind and sun.In year 2015, energy is distributed as follows:
- 34% waste (a doubling of current capacity)
- 30% wind power (equivalent to 35 large wind turbines)
- 28% slurry (equivalent to 200,000 tonnes)
- 6% straw (equivalent to 10,000 tons)
- 2% solar energy (equivalent to 27,500 square meter solar heating)
The electricity will come from wind turbines and the heat from extra district heating and installation of several heat pumps and solar heating plants, and an emphasis on biomass. Transport is traditionally the most difficult point to get diverted to renewable energy and Frederikshavn is working with both electricity, biogas, fuel cells and especially bio methanol. Therefore, Frederikshavn municipality has build Denmark's first bio methanol plant where bio methanol is made of waste, straw and manure. The total investment for achieving the target is estimated to be approximately 1 billion Danish kroner.Source: http://www.energycity.dk/
