Energy sector in transition - technologies and regulatory policies in flux

A transition of the energy sector towards a renewable-based system is one of the challenges that results from the debate on the global climate problems and diminishing fossil fuels. This will demand access to innovations in energy production technologies and usage. However, policies directly focussing on innovation and diffusion of new technologies are losing ground. Policy discussions have been dominated by the liberalisation of energy markets and the introduction of new economic instruments all over Europe. Whether this delegation of responsibility for the transition to new economic instruments provides the expected innovations is questionable. In Europe, Denmark has served as an example country being one of the front runners in the development of energy technologies based on renewable sources, especially wind turbines. But also in Denmark policy preferences have changed from the support for technological innovation and implementation to support for delegating responsibility to a market for green energy and CO2 certificate trading. The different policy regimes marking this change are analysed concerning their ability to support technological innovation. Important elements for the construction and legitimacy of policy regimes comes from academic disciplines involved in policy design. The analysis highlights the basic arguments and the type of knowledge involved and indicates some of the limitations in the measures' ability to solve the problems delegated to them. Experience thus far provides little if any evidence that simple, market-based models can facilitate the need forfuture energy technology innovations in a satisfactory way, which leads to a need for more complex and heterogeneous sets of measures.
