In Peru, there are no regulations mandating that a certain percentage of energy consumption in buildings must come from renewable sources. Legislative Decree No. 1002 stipulates that renewable energy resources (RER) should contribute at least 5% to the total energy consumption in the energy matrix. This percentage, set in 2008, may be increased by the MEM every five years. In 2022, the Ministry of Environment has set a more ambitious target of 20% RER contribution by 2030.
