In order for the European Union to reach its overall greenhouse gas emission targets, each of its member states must adopt the National Energy and Climate (??CP) Plan, a ten-year integrated plan. All five elements of the EU Energy Union are covered under the Energy and Climate Plan, including decarbonization, energy efficiency, energy security, internal energy markets, and research, innovation, and competitiveness. The following goals are listed in the plan: 1) increase the share of renewable energy in gross energy consumption and reduce GHG emissions; 2) ensure energy efficiency by setting goals and timetables for the renovation of the nation's stock of residential and non-residential buildings, both public and private; 3) to increase the diversity of energy sources and the supply from third countries in order to ensure energy security; 4) to develop measures for the internal energy market's interconnectedness; and 5) to expand the use of new technologies and new services in order to make the switch to a sustainable energy system.
