In 1998, Uruguay introduced energy efficiency policy in order to create 437 GWh of energy savings per year, achieving an incremental energy savings of 0.94% per year in comparison to total fuel consumption. Electricity, natural gas and all other "burnable fuels" used in all sectors are covered in this policy. The obligated parties include energy utility companies. The utilities are required to allocated 0.13% of sales to energy efficiency. There are no specific eligible energy efficiency measures. Energy savings are certified by an IPMVP certified professional.
