Current work:
Drivers of energy-efficiency renovations in Ukraine: A case study of the city of Uzhhorod

Dissertation topic:
Residential Energy Consumption in Ukraine: Does Energy Price Matter for Energy Savings?

Disertation abstract:
The dissertation consists of three chapters. The thesis combines two papers that explain the effect of electricity and gas prices on energy savings in Ukraine and a third paper that describes the implementation of energy-efficient measures in Ukraine as a result of a such price increase. All three papers are based on the data received from original household surveys conducted in a period before and after sharp and repeated energy price fluctuations in Uzhhorod, Ukraine. The first paper exploits extreme variation in tariffs over time and across household customers to estimate the price elasticity of electricity demand from dwellings in Uzhhorod, Ukraine. The findings suggest that the price elasticity of electricity demand is -0.2 to -0.5, with the majority of the estimates around -0.3. The elasticity becomes more evident over the first three months after prices change. Only modest evidence shows that response to the price variations is more pronounced for the respondents who were attentive to their bills, consumption levels, or the tariffs. The second paper exploits the tariff reforms in gas prices, aiming to understand if consumers adopt their consumption in response to such changes and estimate the price elasticity of gas demand. To separate the behavioral aspect, only dwellings without energy-efficient renovations were used. Received results suggest that consumers can decrease gas consumption over time, even without renovations. Dwellings that were subsidized by the government were also able to reduce gas consumption. The price elasticity of natural gas demand is around -0.16. The demand becomes more inelastic for households with higher income and heavy users. The third paper describes the types, rates, and prices of various energy-efficiency measures implemented by households between 2008 and 2018 in Ukraine. Data indicate that households follow a step-by-step approach and implement energy-efficiency measures on average over a three-year period deciding to implement up to five different upgrades. Additionally, homeowners with lower education and income, larger household size, and at least one child, living in multifamily buildings, and with a larger number of rooms are more prone to invest in energy-efficient renovations. This probability increases for households that recently moved into their dwelling and if one or more household members work abroad.
