20-20-20 targets for the European Union By 2020, the EU should: increase the share of renewable energy sources to 20 % decrease greenhouse gas emissions by 20 % increase energy efficiency by 20 %
Energy Roadmap 2050 The European Commission issued its Energy Roadmap 2050 in December 2011 the aim is to reduce carbon dioxide emissions by 85 % by 2050 electricity has a vital role in reaching the goal: > total energy consumption decreases > electricity consumption increases

Objectives for Finland Objectives for Finland have been listed in the Long-Term Climate and Energy Strategy approved by the Government in November 2008. Strategy will be updated in the beginning of 2013. decreasing total energy consumption increasing the share of renewable energy to 38 % slow growth in electricity consumption (except for last two years there has been slow decrease due to recession) acquisition of electricity should primarily be based on own capacity > nuclear power will almost triple and wind power increase tenfold during the next 10-15 years

Conclusions of upgradings Upgrading in connection with refurbishment is often very cost-effective Long periods on excess water improve the feasibility Possibility to improve safety and environment-friendliness by totally new solutions Increased value of power and improvement in turbine design have made it possible to achieve bigger power increase in the latest upgradings compared with the first ones
