EU 2020 Climate and Energy Targets

01 EU strategy
Strategic energy Technology Plan (SET Plan)
The Renewable Energy Directive
4
1. Sets mandatory national targets for renewable energy shares, including 10% renewable share for transport, in 2020
2. Creates flexibility by facilitating cooperation between Member States to help reach targets cost effectively
3. Requires national renewable energy action plans
4. Requires reduction of administrative and regulatory barriers, improvements in provision of information and training and improves renewables’ access to the electricity grid
5. Creates a sustainability regime for biofuels
01 EU strategy
National Renewable Energy Action Plans
5
• Planned growth to 2020 leading to 20.6% by 2020
• Majority of Member States to reach or exceed their national targets; 2 -4 MS will partly rely on imports using cooperation mechanisms
• Total renewable energy consumption will more than double from 99 Mtoe (2005) to 245 Mtoe (2020)
• Combined EU renewable energy shares in the 3 sectors in 2020 (projections):
• Electricity from renewable sources – 34% • Heating & cooling from renewable sources– 21,5% • Transport from renewable sources– 11%

Other challenges and opportunities
1. Grid connection can be a limiting factor if the EU grid is not properly designed.
2. Legislation and administrative procedures.
3. Offshore wind is a rapidly maturing and increasing competitive market. Today Europe industry is leading.
4. Reliability is one of the key factors to reduce the cost of energy.
5. Some possible bottlenecks can influence the development of offshore wind:
a) Specialised vessels. b) Submarine cables. c) Adequate ports.
