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
IEA Hydro 2013 / Mr. Aimo Takala
• 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
