In 2016, we were given an award in recognition of our sustainability programs from CEMEFI, which marks the sixth consecutive year we have received this honor. At Guanajuato, the mine is in the middle of the city so we really have to work very closely with the local communities. The most important aspect a company must consider when working in close proximity to a city is ensuring it is a good corporate citizen. This includes the way it treats employees, respect for the environment and integration with the community. At the San Ignacio mine right outside the city, the communities are more rural and some do not even have access to drinking water. We are working with them to provide access to these facilities and we are implementing education programs based on recycling, hygiene and other relevant topics.
In 1999, we became concerned about the availability and cost of energy in Mexico and given that energy represents around 40 percent of our expenses, we started to look at how we could lower costs. We made a strategic decision to integrate our energy supply and start generating our own electricity. In 2016, a total of 81 percent of the energy we consumed was generated in-house. Most of this comes from the petcoke thermal plant in San Luis Potosi, which generates 230MW, and the two wind plants in Oaxaca that generate over 40MW. We also have natural gas turbines in Laguna del Rey, Coahuila and a steam generator in Torreon. There is a new energy law in Mexico that will require companies to procure at least 30 percent of their energy from sustainable sources by 2025. Peñoles has already reached that landmark, because we are convinced of the need for sustainable development.
