Ukraine is facing unprecedented energy security challenges as a result of ongoing geopolitical and financial crises. Improving energy efficiency across the economy could strengthen energy security by decreasing the country’s reliance on fossil-fuel imports, reduce pressure on public budgets that have historically shouldered billions of euros a year in energy subsidies (although some energy subsidies are now being phased out), reduce costs to consumers and improve the comfort and health of its residents. The good news is that there is a large potential for energy efficiency gains in Ukraine. Measures to tap Ukraine’s energy efficiency potential are described in this report titled Energy Efficiency Policy Priorities: Ukraine. More than 80 Ukrainian energy efficiency stakeholders contributed to the findings in this report, which recommends the widespread rollout of residential building envelope refurbishments, installation of building energy control systems and meters, replacement of inefficient appliances and equipment (including motors), information campaigns to reduce wasteful energy consumption and other programmes across sectors.
