Energy Efficiency Innovations in Buildings: Willingness to Pay for Small CHP in Buildings.

The paper uses a choice experiment to evaluate the household's willingness to pay for small CHP in buildings. Small CHP include: reciprocating engines, micro-turbines and fuel cells. Seeking to evaluate willingness of Lithuanian households to pay for energy efficiency improvements in heating the choice experiment was conducted. The results of study estimated willingness to pay of Lithuanian households for small CHP in buildings and as well the main attributes having the biggest impact on their decision and Willingness to Pay. The main drivers of WTP are: investment costs, loudness and size. All these drivers have negative impact for the choice of alternatives. The mean WTP for small CHP in buildings makes 5678 Lt, 7235 Lt and 10361 Lt for reciprocating engines, micro turbines and fuel cells respectively. This indicates that Lithuanian households are willing to pay almost twice for fuel cells comparing to reciprocating engines. [ABSTRACT FROM AUTHOR]
