Aller-Leine-Tal, Germany

Aller-Leine-Tal, Germany

  • Target: 100+% Renewable Power Region, On Its Way to 100+% Renewable Heat.
  • Status: Achieved - In January 2012, Aller-Leine-Tal produced 108% of its electricity with local renewable sources.
  • RES: Wind turbines, biogas cogeneration plant, solar PV farm and small riverine hydro for electricity. Geothermal energy, biomass and district heating grid for heating.
  • Implementation: The region of Aller-Leine-Tal is located north of Hannover in Lower Saxony, Germany. The region consists of eight municipalities (Kirchlinteln, Dörverden, Wietze, Winsen, Hambühren and the administrative divisions in Ahlden, Rethern, and Schwarmstedt). The regional community has reached and surpassed a 100% renewable electricity goal, and is currently pursuing a 100% renewable heating target. Its efforts began in the late 1990's when the region pledged a commitment to help protect the climate by supporting renewable energy use. In 1996, 60 citizens collaborated to construct the first 660kW windmill. This was eventually replaced by a modern 2.3MW turbine. Today, the region is generating energy from additional 54 windmills, biogas (13 MW), solar PV (14 MW), and some smaller river hydro power providing more energy than needed. To achieve 100% renewable heat, the region will expand use of technologies already employed, including geothermal, biomass to heat, a district heating grid, and improving efficiency. To increase energy conservation, the municipalities offer energy audits and energy consulting. They have also initiated educational programs in local schools to engage and educate students in renewable energy-related activities. The idea is that students should experience and understand renewable energy with there own hands and be given the opportunity to use - and build where possible - renewable energy technologies like wind turbines, water mills, and solar chargers. To increase awareness, the region has created touristic bike paths with more than 40 energy stations that provide information on different renewable energy sources. As an energy exporter, the Aller-Leine-Tal has already set a new target of supplying neighboring areas with renewable energy.

Alzey-Land Region, Germany

Fishmarket, Alzey, Germany

  • Target: 100% renewable energy
  • Status: Achieved
  • RES: Wind farms, biogas plants, a hydroelectric power plant and solar power plants.
  • Implementation: The Alley-Land region is a hilly wine growing region comprising 24 local communities, located in the state of Rheinland-Palatinate, Germany. In 2010, the region reached 100% renewable electricity. To also achieve 100% renewable in heating and transportation, it is seeking to further expand its existing renewable energy infrastructure. Today, renewable energy plants in the Alzey region generates more electricity than its inhabitants consume. 38 wind turbines cover more than 91% of the electricity demand. The rest comes from two biogas plants, a hydroelectric power plant and 156 solar power plants.The initiatives in the field of wind power have been largely driven by the private sector. The municipality advises, moderates and creates the planning principles with regards to urban land use planning in order to encourage and guide RES installations. In order to make greater use of wind power, the municipality aims to expand areas for the use of wind power and to identify them in its land use plan. Old turbines will be replaced with newer, more powerful wind turbines to improve the wind power harvest. The Alzey region hosts the largest wind farm in the Rhineland-Palatinate called Park Ober-Flörsheim/Flomborn. Besides wind energy, there are over 150 PV systems installed on private houses, commercial buildings and farm buildings. The Freimersheim solar park produces more than 7.5 million kilowatt hours of electricity each year, able to supply around 2,300 households.

Aspen, Colorado, USA

Aspen, Colorado, USA

  • Target: 100% renewable energy
  • Status: Achieved
  • RES: Hydropower, windpower, and land-fill gas energy.
  • Implementation: The City of Aspen is located in the Rocky Mountains in the state of Colorado. As one of the most famous skiing resorts in the USA, Aspen welcomes many tourists every year. In particular, the city's winter population grows from approximately 7,000 to 50,000 people. This means that Aspen has to deal with a significantly higher energy consumption in winter compared to the rest of the year. In 1885, Aspen was already one of the first American municipalities to use hydroelectric power, and by 2014, hydroplants were covering 86% of the energy demand. The boost in hydropower has been largely due to the Canary Initiative, which was established in 2005, which identified Aspen and other mountain communities as “canaries in the coal mine” with respect to their sensitivity to the effects of climate change. The initiative laid out a Climate Action Plan, which would reduce GHG emissions by converting its energy supply to one based on RE. In cooperation with the National Renewable Energy Laboratory the city developed a strategy how to achieve this. Investments in renewable energy have enabled the utility to progressively replace fossil fuels. Finally, in August of 2015, the City of Aspen municipally owned electric utility achieved 100% renewable energy, by signing of a contract with the Municipal Energy Agency of Nebraska, a wholesale electric energy provider. Since then, the energy mix in the electricity sector is assembled by 46% hydro, 53% wind and 1% landfill gas energy. The new wind contract, which provides 95% of the new renewable energy, allows the city to only buy what it needs to keep it close to 100% renewable energies. The advantage of this arrangement is that it affords crucial supply management flexibility for dealing with inconsistencies in energy production from Aspen’s other resources, such as the fluctuations in hydro power. It also allows the city to avoid being forced to buy energy they do not need.

Beaverton, Oregon, USA

Beaverton, Oregon, USA

  • Target: Achieve 100% renewable energy target including all public buildings, streetlights, and the water supply. 80 percent carbon emissions reduction below current levels by 2050, with a near-term emphasis on 40 percent reduction by 2030.
  • Status: Achieved - Since 2014, 100% of electricity fed into the city's grid comes from wind power sources. It is the only city in the state of Oregon that procures all of its power, for civic operations, from Portland General Electric’s (PGE) renewable energy program.
  • RES: Windpower and solar.
  • Implementation: In the first instance, Beaverton created an Energy Map for the base year of 2012, and researched existing and proposed state laws. To achieve the energy target, the electricity that Beaverton uses is not sourced from renewable energies produced in the town, but through investments in renewable electricity, which offset the consumed power in the city. Beaverton teamed up with PGE to purchase renewable energy offsets equivalent to all of the electricity demands for the city. The renewable energy purchased powers the city’s street lights, traffic signals and water pumping. PGE acts as a public consultant and encourages the community to switch to 100% renewable energy via different green products and packages which they can can select according to their needs. Competitions and projects enhance the level of participation of community members, such as the Beaverton Better Buildings Challenge (Beaverton BBC) which aims to improve energy efficiency in local buildings 20% by 2020. The city provides participants of the program free energy consultation, assistance prioritizing efficiency projects and support with utility data tracking tools.

Bozcaada, Turkey

Bozcaada, Turkey

  • Target: 100% renewable electricity
  • Status: Achieved
  • RES: 17 turbine wind farm, solar arrays, hydrogen energy.
  • Implementation: Bozcaada is an island of Turkey in the northeastern part of the Aegean Sea. It currently generates more power than it consumes. In 2000, a 17 turbine wind farm was constructed with a nominal power capacity of 10.2 MW energy, and produces 30 GWh of electricity every year. This is the equivalent consumption of 17,500 households or 30 times the consumption of the whole island of Bozcaada. The excess electricity produced is fed to mainland Anatolia through an underground and partly undersea cable. The hospital and governor’s mansion on the island uses hydrogen energy produced by local renewable energy sources. At the governor’s mansion, energy is captured with a rooftop 20 kW solar array and a 30 kW wind turbine. The electricity produced is used to electrolyze water into hydrogen. This gas is stored compressed and used later to generate energy or as fuel in hydrogen-powered cars.

Bruchmühlbach-Miesau, Germany

Bruchmühlbach, Germany

  • Target: 100% renewable energy
  • Status: Achieved
  • RES: Wind farms, biogas cogeneration plants, a solar PV plant, and rooftop solar systems.
  • Implementation: The municipality of Bruchmühlbach-Miesau consists of several small towns and villages, located in the state of Rhineland-Palatinate in the west of Germany. The town of Miesau in particular is well-known for the “Miesau Army Depot” (the largest American ammunition depot outside the US). The town is also just a few miles from the famous Rammstein Airbase and Landstuhl Medical Centre. Today, Bruchsmühlbach-Miesau is also known for its 100% renewable energy supply systems. In order to achieve this 100% goal, the mayor initially approached the US Army authorities with the plan of placing a 1-MW solar PV plant on the roof of storage buildings within the military base. The project was finally approved in 2012 by the local American military authorities and the national German authorities, and following this success, the municipality began planning for a biogas cogeneration plant to be built, also with the US base's cooperation.

    The plants proposed were to help boost the municipality's existing energy infrastructure. By then, it already operated a wind farm consisting of 10 turbines that generated about 37 GWh/a, a biogas plant that generated 2.7 GWh/a, and over 200 rooftop solar systems generating 2 GWh/a.  When a 5 turbine wind farm was completed in 2013, it produced an additional 47 GWh/a. At this point the community of Bruchsmühlbach-Miesau was able to produce 290% of its electricity demand. The wind farms especially enjoyed good support in the area due to strong local participation and the emphasis on regional value creation.

Brunico (Bruneck), Italy

Brunico (Bruneck), Italy

  • Target: 100% renewable energy
  • Status: Achieved
  • RES: Solar thermal systems, solar photovoltaics, small hydro plants, biomass plant, biogas plant, and district heating network.
  • Implementation: Brunico, Italy is a town in South Tyrol. Today, the town is producing more electricity and heat than it consumes. It has an array of renewable energy systems installed. For heating, it has 840 m² of rooftop solar thermal systems supplying water heating, a 120 km district heating network fed by a 9 MW biomass plant and a 1.5 MW biogas plant near a landfill site supplies heat for more than 2000 buildings. Electricity for around 1500 families comes from 3 MW of rooftop photovoltaic panels, small hydro plants totalling 4.4 MW, and a 20 MW biogas plant that is fed by wood waste. The town additionally has a large 46.3 MW hydro project from its prior electricity system that is not counted toward the renewable energy total. The elementary school and fire station are entirely energy independent with their solar PV installations of 32 kW and 64 kW respectively. Brunico’s School Centre is additionally able to meet part of its heating requirements with 750 m² of vacuum tube collectors that heat up 3000 m³ of undeground tanks. The hot water is pumped through radiators and radiant floor heating panels.

    To support Brunico’s renewable energy commitment, town policy requires  that all local buildings meet up to 25% of their own energy needs with renewable sources, including 50% of their hot water demand. Italy's feed-in tariff law, like the German feed-in tariff provides a great incentive to the town. The law guarantees connection to the grid for renewable energy producers of all sizes and reasonably priced payment differentiated by technology for all the renewable electricity they generate.

Burgenland, Austria

Burgenland, Austria

  • Target: 100% of its electricity from local, renewable sources by 2020
  • Status: Achieved - Burgenland managed to supply 100% of its electricity needs through wind power by 2013.
  • RES: Wind power and biomass energy.
  • Implementation: Burgenland is the seventh largest of Austria's nine states. It borders the Austrian states of Styria and Lower Austria, as well as Hungary, Slovakia and Slovenia. Today, this region in eastern Austria gets 100% of its electricity from local, renewable sources . It all began in 1992, when a local citizen wanted to install a wind turbine on his property and contacts a wind power consultancy. The consultancy recommended to build a large farm in view of the site’s high wind power potential. In the following year, the owner and the consultancy presented the project to the Zurndorf town council. Between 1993 and 1995,  planning and wind measurements were undertaken. In 1994, the municipality decided to create a company for managing the project (where the municipality has a 98% stake). By 1995, the membership of Austria to the European Union, meant that the Burgenland could benefit from EU Structural Funds to carry out infrastructure projects, such as energy. By 1997, the Austrian government decided to increase the share of renewable energy to 3% of final energy use, beginning with the construction of the Zurndorf wind farm. In 2001 the Austrian electricity market was open, and in 2002 Burgenland developed a regional wind power plan. In 2003 the Green Power Act was adopted. By 2009, the Burgenland Energieteam was established to set an energy self-sufficiency target by 2050, accompanied by an action plan. By 2013 self-sufficiency in electricity was already achieved. It is estimated that 4,500 jobs have been created through the development of wind power in Burgenland.
