Litoměřice's approach to the local energy transition is twofold, consisting of incentives for small-scale renewable energy applications on the one hand and a large investment in geothermal heat and energy production on the other.

Coal-fired water boilers had been phased out and replaced with gas-fired boilers in the 1990s. When gas prices rose, people were inclined to use coal again which would bring back smog. Thus, in the year 2000, the municipal government introduced a subsidy to apartment or hose owners willing to replace coal boilers with solar water heaters who could combine it with state grants. The council has suppoted the development of small hydro power plants (8.7 MW) and has installed solar thermal as well as photovoltaic systems on public buildings (1,216 MW). At the larger scale, Litoměřice's town council has decided to exploit geothermal energy. Based on an in-depth territorial analysis, preparations for an ambitious geothermal heat and electricity production plant with an output up to 40 MWt and 5 MWe were launched in 2008.

 

Results

As the geothermal power plant is not finished due to financial and other constraints, Litoměřice continues to rely on coal-fired plants for most of its energy needs and the goal of 100% renewable energy is still far away. However, the town's gradual appraoch to promote clean energy has yielded several positive impacts. Litoměřice's SWH subsidy programme has earned the city nationwide attention. Litoměřice won several awards in the Czech Solar league at the European RES Champions League (2010). In 2014, around 5% of households had installed SWHs (1750 m2 in total).

Inspired by local support programs in neighboring Germany, Litoměřice's approach is now inspiring other cities. Together with three other Czech cities, Litoměřice set up a municipal energy manager association in November 2014.

The Ecoparc de Barcelona is an ambitious environmental facility which not only treats solid waste from the metropolitan area but aims to reuse and recycle elements through a range of techniques, such as composting and methanization.
 
Background
Metropolitan Barcelona produces 1.6 million tonnes of solid waste (excluding industrial waste) annually. The idea for the Ecopark emerged in 1998, following the adoption of the Metropolitan Municipal Waste Management Programme (PMGRM). The main objective was a large-scale transition from mere treatment of solid waste to a system which allowed for the recovery of materials and energy
resources and the reduction of landfill waste.
 
Activities
Built between 1999-2001 at a cost of €48 million, Ecopark de Barcelona is a waste sorting and biotreatment plant for Barcelona and neighbouring towns. The plant’s main aims are to limit the environmental impact of solid waste treatment; improve plant health and safety conditions; increase production of biogas; increase the production of compost; minimize factory discharges (waste we are unable to make use of); minimize the percentage of organic matter in factory discharges; recover the maximum amount of recyclable material
possible1. Ecoparc de Barcelona treats two kinds of waste: organic waste from selective collection and undifferentiated waste (residual waste). From the former biogas (methane and carbon dioxide) is produced, which is then used to generate electricity. From the latter recyclable materials (e.g. paper and glass) and organic matter (used to make compost) are extracted. Steam is also sold to a local cooling and heating network.
 
Results
Ecoparc de Barcelona treats approximately 12% of solid waste produced in the metropolitan area. From the c. 350,000 tonnes of solid waste treated per year, it produces 160,000 MWh per year. Around 7.6 tonnes of steam sold per year to urban heating and cooling network2.
