Biomass is the most-used renewable energy source, not including biofuels used in vehicles. More than 3,000 thermal biomass installations (to produce heat) are in service in Euskadi, with installed capacity of over 100 MW, in places such as sports centres, cultural centres, public institutions and industries, housing, etc.
One of the most abundant biomass resources in Euskadi is forestry biomass, as there are sufficient resources of wood to cover the heating needs of the buildings of the different public administrations. Specifically, Basque forests have stocks of potentially-exploitable wood products of over 62 million cubic metres. This is a large amount of energy stored in our forests which, far from being exhausted, continues to rise and represents an opportunity to generalise the use of a locally-produced and renewable energy source, at a competitive price in relation to commonly-used fuels for heating, also generating employment in rural areas in the process.
