The multi-lingual Europe's Energy [publicdata.eu] aims to put European energy policy (including the 2020 energy targets) into context. This interface attempts to augment Joe Public's patchy and anecdotal understanding of energy issues across Europe in order to have a more informed debate or enable an objective evaluation of the kinds of options that are viable.
Based on the data from Eurostat, the visualization compares different EU countries in terms of their carbon emissions, renewable energy share, energy dependency, net imports, and progress towards their respective renewables targets. People can find out how much energy different EU countries consume, how they consume it, and how this has changed in recent years. Alternatively, one can explore how much energy different EU countries produce, what the energy mix is like in different countries and how this has changed in recent years.
