In general, it is unlikely that advanced research activities will be located in rural areas. However, as the technology to produce energy from renewable sources is not mature, empirical research needs to be done in the field, where the installations are located. The deployment of renewable energy, however, does not depend on research and development (R&D) alone. Learning by searching is just one part of a much broader system based on the transfer of knowledge among actors engaged in the innovation process. As suggested by Lundvall (1992), there are three other kinds of learning, besides learning by searching, that should be taken into account when assessing regional innovation systems: learning by doing, learning by using, and learning by interacting.
