Abstract
Electrical energy and demand is constantly increasing disproportionately. Therefore, taken at Community level long-term programs such as the Europe 2020 strategy, which is primarily focused on the energy sector. Its priorities include reducing greenhouse gas emissions, increase energy efficiency through the development and introduction of innovative technologies and increasing the share of renewable energy sources (RES) at Community level. The issue of implementation of energy from renewable sources in addition to the existing EU environmental strategies key area where attention is focused policy. Therefore, we can expect a significant inflow of funds into the development of these strategic concepts. Improving the energy efficiency is one of the key strategic approaches, contributing to the achievement of greenhouse gas emissions in Community.
