The Bulgarian economy is by far the most energy intensive in Europe and it is highly dependent on other countries for its energy and therefore the economy - and in turn individual households are vulnerable to price changes. A quarter of energy consumed in Bulgaria is used in the residential sector. Actively reducing the energy consumed by end users will be the fastest and most cost-effective method of making further energy savings, and also has related benefits such as lowered reliance on energy imports and lower fuel bills for consumers and businesses.
