Chile’s Metro de Santiago has signed two agreements to utilize solar and wind energy to power their largest metro system in Latin America. Both solar and wind energy will control about 60 percent of the metro’s energy needs by the year 2018. President Michelle Bachelet signed the $500 million deal to help reduce their carbon footprint and provide a sustainable future for everyone. Construction of the solar plant will supply 300 gigawatt hours per year of renewable energy to Metro de Santiago; that is 42 percent of its yearly energy demands.  The remaining 18 percent of power will consist of 185-megawatts of wind power. The Chilean metro project will alleviate 130,000 tons of CO₂ emissions per year.
