On 15 December 2015 the European Parliament adopted a non-binding resolution entitled “Towards a European Energy Union”.

The resolution calls for a fully integrated European energy market and focuses on the issues of security of supply, energy efficiency as a “first fuel” and sustainable economy, in particular the decarbonisation of the transport sector. It mentions the energy efficiency potential in buildings and stresses that “it is necessary to increase both the depth and the rate of building renovation” (para 97). The resolution was voted with a large majority 403 votes to 177, with 117 abstentions.
