In a world undergoing a paradigm shift in terms of energy:

> global energy consumption is increasing;

> the cost of fuels and CO₂ is rising;

> climate change is seen as a global challenge,

EDP is commited to a sustainable strategy in which the use of renewable energy sources, along with the promotion of energy efficiency plays a key role.

Investments carried out in recent years on renewable energy, including wind farms and hydroelectric powerplants, led EDP to a position of leadership in this area.

At the end of 2011, EDP had a overall balanced energy mix from conventional power plants (fossil fuels) and renewable (wind, hydro and biomass), representaing 63% of total installed capacity. Since 2009, more than half the electricity produced comes from renewable sources (64% in 2011).
