Thank you, Portugal, renewable energy works!
Running entirely on renewable energy for four days
The new Renewable Energy Directive, adopted on 23 April 2009, sets the target of generating mandatory 20% of EU energy consumption from renewable energy sources by 2020. The EU also has longer strategic vision and targets of energy consumption, such as Energy Roadmap 2050, where decarbonisation scenarios indicates a renewable energy share of at least 30% by 2030.
In the case of Portugal directives are efficient and effective as before 2009 the country was considered one of Europe’s biggest producers of CO2 emissions (the target to reach 31 per cent share of renewable energy sources by 2020 is surpassed only by Austria, Latvia, Finland and Sweden).
