European Union and member states are partially on target for meeting the EU-wide 20% of energy from renewable sources by the year 2020. Though some sources need to be further developed, others such as photovoltaic and wind are very close to becoming sustainable, with investment, economies of scale and cross-border cooperation driving down costs. “Europe needs to move away from thinking about developing renewables in terms of sovereignty and realise that it is just plain and simple self-interest,” commented Philip Lowe, European Commission Director General for Energy.
