Reducing greenhouse gas emissions by at least 55% by 2030 requires higher shares of renewable energy and greater energy efficiency in an integrated energy system. The RS produces electricity from different sources. The Thermal power plant "Ugljevik”, a relatively small plant, emits unimaginable amounts of dangerous sulphur dioxide. Bearing in mind the share of energy from fossil fuels, the question for the RS is how to provide enough energy to future generations? The development of the RES production in the RS is a crucial challenge for policymakers nowadays. This transformation will improve our health and well- being, create jobs, generate investment and innovation, reduce energy poverty and dependency on energy imports and strengthen the security of supply.
