Policy insights for wind energy from a choice experiment stated preference efficient design in Apulia region (Italy)

The present work argues that wind energy is either a positive or negative determinant against the risks associated with its use, and aims at: evaluating the incidence of energy risks on the perception of wind energy; analysing the trade-offs between a wind farm installation, land conservation and energy risks; suggesting adequate policy indications for the efficiency of future energy markets. The study compares the results from logit models, which estimate the distribution of the utility coefficients with a Choice Experiment approach using a stated preference efficient design and honesty priming techniques to overcome the hypothetical bias. Main findings indicate a positive attitude for the proposed wind energy scenarios in terms of Aesthetical impact, CO2 and Bill savings, and Costs, as well as more densely distributed wind farms producing more energy. Installation and maintenance costs and the rate of avian collisions are considered acceptable. From the main findings, useful policy insights assess the efficiency of wind farms projects to reduce costs and energy prices. Simplification of bureaucracy, direct economic benefits for local communities, citizens’ participation, and dissemination of information are key practices for future developments of wind energy markets.
