fossil fuels, increasing their contribution to the Spanish energy mix with respect to PER considerations until achieving a contribution to gross electricity consumption of 32% in 2012 and 37% in 2020. (ii) Measures Encourage actions that favor those less developed such as biomass, and thermoelectric and photovoltaic solar energy, stimulating investment in technological development that lowers current installation costs.. Promote small photovoltaic installations of less than 5 Kw., through the improvement of the premiums of the conditions of access to the network and the administrative procedures for obtaining subsidies and applications for connection permits. Increase in hydraulic use through the rehabilitation of closed mini-power plants, improvement of existing ones and installation of turbines in reservoirs that lack them. Provide investments in renewable energies and cogeneration with a framework of greater economic security that contributes to their strengthening, evaluating an improvement in the bonuses that the Tax on Economic Activities grants to companies that use or produce Provide investments in renewable energies and cogeneration with a framework of greater economic security that contributes to their strengthening, evaluating an improvement in the bonuses that the Tax on Economic Activities grants to companies that use or produce these energies. The goal is to make them sufficiently competitive against conventional alternatives. One of the instrumental elements to materialize the above points is the review of RD 436/2004, already approved by the Government (RD 661/2007).. Consideration of biogas, biomethanol, bioETBE, synthetic biofuels, biohydrogen and pure vegetable oil as biofuels (according to Directive 2003/30/CE), studying the possible need to modify Royal Decree 61/2006. The objective is to establish an effective integration of renewable energies in the transport and building sector. Encourage the creation of new biofuel plants (bioethanol and biodiesel) that increase capacity and allow demand to be met in 2010 and its increase in the period 2011-2020. Encourage technologies based on hydrogen as a fuel, taking into account the environmental implications, particularly with regard to the use of renewable energies for the production of hydrogen. cleaner fuels, including biomass (pellets and chips), progressively substituting coal consumption with the aim of achieving its complete substitution by 2012. Help the development of projects that develop these energies in
