According to these forecast reports, states like France and the Czech Republic are going to reach this 20% target, while others such as Spain, Germany, Sweden, Denmark and  Estonia even announced they will be able to exceed this goal. These leading countries in terms of renewable energy use “expressed an interest in transferring the volumes that exceed their indicative trajectories to other countries to help them achieve their goals”, Euractiv reported. This could concern Belgium and the Netherlands for instance: the two countries are not so confident that they will be able to increase their share of Renewables up to that point by 2020.

According to several states’ Representatives, the EU member states will have to bet on energy cooperation projects and improved grid interconnections to take advantage of the huge untapped potential of renewable energy sources all across Europe. For example, a pan-European Solar Plan is in the pipelines, as well as offshore wind parks in Germany. Within the frameworks of the Trans-European Energy Networks (TEN-E), the EU is also planning a massive North Sea grid for renewable energy that could meet up to 10% of Europe’s energy needs. "If Europe is able to develop a super-grid it will be a vital ingredient in the fight against climate change because it will allow large-scale integration of renewable electricity production”, Justin Wilkes, policy director of the European Wind Energy Association (EWEA), told Deutsche Welle on 5 January 2010. Not only will such projects enable member states to meet the 20% objective for renewable energy use, but they will also contribute to cut greenhouse gas emissions and bring down energy use by 2020, according to the Climate and Energy Package 20-20-20 commitment.

Spain is said to be very ambitious and optimistic about its capacity to comply with its renewable commitment under the Climate and Energy Package. Mischa Bechberger, international affairs manager at the Spanish Renewable Energy Association (APPA), said that the renewables sector was "surprised positively" by the fact that the government had sent out a message that it was expecting to overshoot the target by nearly three percentage points. "But there are surely some question marks, mainly about the high energy-efficiency evolution they assume and also the connection to the Europe-wide electricity grid", he cautioned. "This is in any case one of the major preconditions for renewable energy in Europe in general, but in Spain – having only minor interconnection capacities with the European grid – in particular."

The Spanish Presidency of the EU announced in its official programme that it is to work for greater interconnections of national renewable energy grids. The national action plans that EU countries will have to submit before the June deadline could include measures which go in this direction.
