and SENER. The Environment and Natural Resources Secretariat (SEMARNAT) is responsible for environmental policy and the preservation of renewable and non-renewable resources, while SENER defines the national energy policy. CONAE, the National Commission for Energy Savings, is responsible for promoting energy savings and energy efficiency. Finally, SEDESOL, the National Secretariat for Social Development, includes the promotion and use of renewable energy in some of their projects. The Renewable Energy Development and Financing for Energy Transition Law (LAERFTE), which entered into force on November 28, 2008, mandated SENER to produce a National Strategy for Energy Transition and Sustainable Energy Use and a Special Program for Renewable Energy. The Special Program contains tentative targets for renewable generation for different technologies. Those targets will be revised as SENER and CRE advance in the completion of the activities included in the law. Hydro About 19% of the electricity produced in Mexico comes from hydroelectric resources. The largest hydro plant in Mexico is the 2,400 MW Manuel Moreno Torres in Chicoasén, Chiapas, in the Grijalva river. This is the world's fourth most productive hydroelectric plant. The 750 MW El Cajon hydroelectric plant in Nayarit, which started operations in November 2006, is the latest completed large project. The country has an important mini-hydro potential, estimated at 3,250 MW (in the states of Chiapas, Veracruz, Puebla and Tabasco) In 2009, there were 22 private mini-hydro installations (12 in operation, 2 inactive and 8 under construction), adding up to a total of 83.5 MW in operation, with 105 MW under development. The number of publicly owned hydro plants in 2009 was 42: 31 of them (270MW) belong to CFE, while the remaining 11 (23.4MW) belong to LFC. Solar Mexico is the country with the world's third largest solar potential. The country's gross solar potential is estimated at 5 kWh/m2 daily, which corresponds to 50 times the national electricity generation. Currently, there is over 1 million square meters of solar thermal panels installed in Mexico, while in 2005, there were 115,000 square meters of solar PV (photo-voltaic). It is expected that in 2012 there will be 1.8 million square meters of installed solar thermal panels. The project named SEGH-CFE 1, located in Puerto Libertad, Sonora, Northwest of Mexico, will have capacity of 46.8 MW from an array of 187,200 solar panels when complete in 2013. Wind Wind power production is still very limited in Mexico, although the country's potential
