BRITO Portugal Session 4 – Block 1 Barcelona May Introduction The 1973 oil crisis lead to a global change of the European energy politics in an attempt to reduce external dependence. Some priorities were defined: Diversify the oil supply; Promote the saving and the rational use of energy; Develop the internal sources of energy.
BRITO Portugal Session 4 – Block 1 Barcelona May Renewable Energy Sources Renewable energy sources achieved greater importance, as a main contribution to the global security in terms of energy supply Some priorities were defined: Research; Development of new technologies; Legal context.
BRITO Portugal Session 4 – Block 1 Barcelona May Legal Context Technical definition of the plants connection to the grid; Remuneration process assured; Obligation of purchasing the energy emitted to the grid; Support to the investment.
