The effects of policies providing information and trialling on the knowledge about and the intention to adopt new energy technologies

Abstract
To increase adoption of new technologies many scholars suggested policies including information and trialling. This study reports on a randomised control trial (RCT) investigating whether information on and experience with Battery Electric Vehicles (BEVs) can alter knowledge and purchase intentions. A large (N = 4149) random sample of conventional car holders was randomly divided into three groups: one receiving comprehensive information on BEVs, another getting the same information plus an actual multi-day test drive with a BEV, and a control group without any intervention. For the first time, information and test-driving were assessed side-by-side in their effects on technology knowledge and adoption intention. This study shows that test-driving treatment largely (by 11%) and significantly increased BEV purchase intentions for a large group. Therefore, policymakers should facilitate direct experience to promote shifting individual motorised transport to electric vehicles in light of energy independence and climate considerations.
