Ukraine has substantial untapped potential for energy savings, estimated at 19 million tonnes of oil equivalent per year, even without including transportation. While energy consumption declined 25.7 million tonnes over four years, only 25% was due to efficiency improvements, with 77% of energy savings from the residential sector after gas and heat tariff hikes in 2015. Ukraine scores poorly on energy efficiency policy assessments, with opportunities in data collection, continuing fuel subsidy removal, and leveraging private investment in efficiency. Priority areas are enhancing energy data analysis, further raising energy prices, and establishing financing mechanisms for residential and private sector efficiency projects.
