Despite efforts to move toward the energy transition, Catalonia continues to rely significantly on fossil fuels. This dependence is particularly notable in transport (with petroleum products) and energy demands (where natural gas plays a key role). In a context of geopolitical instability, this direct connection to external markets not only represents a strategic problem—it also weakens competitiveness.
Nevertheless, some steps taken indicate a change of course. One clear example is the decarbonization of heating and cooling demands driven by the growing popularity of heat pumps. Besides helping to reduce emissions, these devices serve as a means of adapting to climate change—especially with the increasing demand for cooling systems.
In the building sector, heat pumps are installed primarily in commercial and tertiary buildings such as hotels, hospitals, sports centres, or office buildings, due to their high thermal demands. One notable example is Bloc4BCN, a public-cooperative project located in a former industrial space at Can Batlló that was renovated and ceded to the Bloc 4 Association by the Barcelona City Council. There, businesses, organizations and projects share resources, knowledge, and values. Beyond cooperation, Bloc4BCN seeks to serve as the vanguard for the energy transition with the installation of solar panels and heat pumps (aerothermal and geothermal), as well as energy management and efficiency systems that convert it into a true testing ground.
