Barcelona’s residential consumption accounts for 30% of the total energy consumed in the city.  As for household consumption, roughly 28% comes from domestic hot water; 25% from central heating; 39% from appliances (electrical household appliances and others); 7% from lighting and 1% from refrigeration.

Consumption in the commercial sector represents 34% of the total consumption in Barcelona. This consumption, by the commercial sector and the services sector (without taking into account large facilities), is distributed in the following way: 5% comes from domestic hot water; 27% from heating; 17% from air-conditioning, and 51% from machinery and electric equipment (except air-conditioning).

These data correspond to the figures from Barcelona’s latest energy assessment, published in 2018.

That is why it is vital to work to save energy both in the home and in the workplace, not only to contribute to reducing greenhouse gas emissions, but also to reducing your electricity bill.

Calculadora energètica

Per poder estalviar millor és recomanable, en la mesura del possible, fer una auditoria energètica que permeti plantejar una sèrie de millores en matèria d'eficiència energètica per reduir els consums d'electricitat, gas i aigua. A la llar, es pot dur a terme una auditoria simplificada o utilitzar eines com la calculadora energètica.

Rehabilitar per estalviar

L'Ajuntament de Barcelona impulsa anualment ajuts a la rehabilitació d'habitatges orientats a la generació i estalvi d'energia.  

Promoting electric vehicles

 

Barcelona has a wide range of shared electric vehicle services (mopeds and cars) to solve journeys that cannot be made by public transport, on foot or by bike.
