Immediate effect from an increased share of electricity from renewable sources is the reduction of greenhouse gas emissions as this production does not generate any emissions. Bulgaria has a significant potential of renewable energy sources and the encouragement of investments therein directly contributes to diversification of the energy mix and to slowing down the process of exhaustion of local energy resources. An important aspect here is the decentralized production of energy and the consumption of energy from renewable sources by households. The specific measure to be implemented is to increase the share of energy for heating and cooling from renewable sources which will contribute to reducing greenhouse gas emissions by 488000 tonnes by 2020.
