Here you will find information on anything to do with the energy model, energy supply, energy saving and power generation, in fact, everything you need to know, in the three languages.
How much energy can you generate?
Barcelona City Council, through the Barcelona Energy Agency (AEB) and the i.lab programme, with the support of the BIT Habitat Foundation, have launched the challenge entitled "Energy-generating floors: how can we incorporate local renewable energy generation into the city's floor surfaces and pavements?" with the aim of finding potential solutions for the local generation of renewable energy in floors and studying the feasibility of implementing them in Barcelona’s streets, squares and access roads.
With this goal in mind, we are looking for solutions to pilot test the generation of renewable energy in the city’s floor surfaces and pavements and assess the results over a six-month period.
Many of Barcelona's buildings have suitable conditions for installing energy-generating equipment on their roof terraces. The City Council has compiled Barcelona's Energy Resources Map so it can find out all this energy-generating potential.
The map classes buildings according to their energy yield (photovoltaic solar, solar thermal or mini wind power), and, what is more, gives information on the energy that could be generated, the greenhouse-gas emissions that could be cut and the estimated cost of the investment that would have to be made.
The map provides an area of 7,899,532 m2 for capturing sunlight, taking into account the fact that sunlight-exposed roofs are considered as optimal for solar-energy generation.
According to these data, the generating potential of roof terraces is:
- 1,191 GWh per year of solar photovoltaic energy, a quantity that is equivalent to roughly 50% of the electricity consumption of Barcelona’s domestic sector in 2012.
- 5,495 GWh per year of solar thermal energy, which is equivalent to the annual consumption for obtaining sanitary hot water for some 4,000 Les Picornell-size swimming pools.
