ObjectiveWind power is an endless and renewable source of energy that has been used for thousands of years. It plays an important role in Umeå Energis investment in renewable energy and is in line with the company’s aim to be completely carbon neutral by 2018. In total, the municipality owned company Umeå Energi owns ten wind turbines, which provide significant climate benefits. These turbines are situated in the towns of Hörnefors, Holmsund and Robertsfors. Hörnefors wind power plant consists of eleven turbines with an output of 2 MW each from two different manufacturers, Vestas and Enercon.

SectorsObjective
Smaller-scale wind turbines can be found in a wide range of applications including off-grid power; either directly by charging a storage battery or in combination with another form of generation to cover intermittent periods when there is little to no wind. In such instances small wind may be cost effective depending on the costs of alternate off-grid technologies and fuel prices; however the overall contribution of small wind to climate change mitigation will probably be limited due to the long payback periods required to offset the carbon used in their manufacture.

SectorsObjectiveThe conversion of kinetic energy in wind into electrical power is known as wind energy. There are a number of ways in which this conversion can be done but the design dominating the market is known as the horizontal axis wind turbine (HAWT) with its archetypal three-bladed rotor. Wind energy is actually a form of solar energy; the temperature differences caused by the sun shining on the earth act, along with other factors, to cause large bodies of air, winds, to move across the face of the planet.

SectorsObjectiveThe district heating net is a pipe network that supplies heating and hot water for connected consumers from a central power plant. It is a more efficient way to provide heat and power compared to localized boilers. District cooling is the cooling equivalent of district heating. Working in accordance to similar principles, district cooling delivers chilled water to buildings like offices and factories. Trigeneration is when electricity, heating and cooling are combined in the same plant.

SectorsObjectiveWind energy technologies can be classified into two categories – macro wind turbines that are installed for large-scale energy generation such as wind farms, and micro wind turbines used for local electricity production. Micro wind turbines are suitable for application at the building scale and are called ‘building-integrated wind turbines’. The main components of a wind turbine include blades, rotor, gearbox and generator. Small wind turbines were originally designed with a horizontal axis, also known as HAWTs.
