EU legislative instruments
Many legislative measures towards EU renewable energy sources are linked to reduction targets declared in the Kyoto Protocol in 1997, which commits its signatories to reduce greenhouse gases (CO2, CH4, N2O, HFCs, PFCs and SF6), an average of 5.2% by 2008-2012 compared to reality in 1990. The basic documents supporting the use of renewable energy in the EU for the period until 2010 the White Paper "strategy and action plan" (http://ec.europa.eu/index_sk.htm) of 26 11th1997th It includes an ambitious target of increasing the share of renewables in total primary energy sources from 6% in 1997 to12% in 2010. Based on the White Paper the European Commission launched in 1999 initialization campaign (1999-2003), under which sought to stimulate the development of renewable energy use. Result of the efforts of this period, the Green Paper on a European Strategy for Sustainable, Competitive and Secure Energy "Towards a European strategy of energy supply" (http://ec.europa.eu/index_sk.htm) of 8 March 2006, which underlines that the EU is extremely dependent on external energy supplies and it is therefore necessary to diversify and provide different kinds of energy balance. To achieve the goal directed a series of incremental steps in different sectors. So far, the EU also adopted guidelines for the RES.
