&gt; The commitments already acquired as of today (July 2011) will account for 76% of the equivalent premium for electricity generation with renewable energies that will be produced in 2020. Future commitments, which will represent more than half of the energy generated with renewable energies in 2020, will only represent an extra cost of about 1,500 million, which represents 3% of the total costs of the system for that year (about 49,500 million). &gt; In the group of technologies that can become competitive with the electricity market in this decade, the one that stands out the most for its potential and for the possibility of developing it immediately is onshore wind power. There is a group of technologies with enormous potential (solar, marine energy, biomass residues) that can become competitive in the next decade and that will be the basis for increasing the share of renewables in the future. In the high acid scenario, most of these technologies could become competitive before 2020. A good number of renewable energies show positive competitiveness against a natural gas combined cycle, taking into account the total costs of this technology. Even considering 5,000 h/year of use for this technology, currently onshore wind power and the rehabilitation of mini-hydro plants have lower costs than a natural gas combined cycle. &gt; The cooperation mechanisms foreseen in the Renewable Energy Directive can also contribute significantly to cost reduction. In the considered scenario of transmitting 0.4 Mtoe to other Member States (51.5% of the expected surpluses), the savings could be valued at around 245 million, if the sale price were the average value of the equivalent premium for the set of renewable energies. Around the year 2020, the main component of the price of electricity will be the cost of energy, which will represent 57.2% of the total costs of the system. Access costs will reduce their weight from 59% in 2010 to 42.8% in 2020. The impact of the renewable energy promotion policy on the total costs of the electricity system, and therefore on the price of electricity, is reduced throughout the 2010-2020 period, despite the significant increase in generation. In 2020, the equivalent premium will represent only 13.2% of the total costs of the system. &gt; In the scenario
