We examine the effect of energy prices and technological knowledge on innovation in green energy technologies. In doing so, we consider both demand-pull effects, which induce innovative activity by increasing the expected value of innovations, and technology-push effects, which drive innovative...

This paper explores cost-effective low-carbon R&D and capital investment portfolios for the electricity generation sector through 2060. We present a novel method for long-term planning by combining an economic model of endogenous non-linear technical change and a generation capacity planning...

The paper analyzes the relationship between CO2 mitigation policy and promotion policies designed to deploy renewable energy sources for electricity production (RES-E). If an emission cap is the only policy target, an optimal mix consisting of high and low carbon use of fossil fuels, deployment...

[Vorwort] Das 1. Symposium für Ökonomie im Gartenbau fand am 27. November 2013 in der Paulinerkirche in Göttingen statt. Es wurde als Kooperation der Georg-August-Universität Göttingen, des Thünen- Instituts für Betriebswirtschaft und des Agrarkompetenznetzes WeGa durchgeführt. Die...

We argue that expectations about future energy use affect the transition from fossil fuels to renewable substitutes, because of an interaction between innovation and resource scarcity. The paper presents a model of directed technical change to study this interaction. We find that resource-saving...

Technological change and gains in efficiency of renewable power generation technologies are to a large extent driven by governmental support. Various policies that can broadly be categorized as technology push, demand pull or systemic constitute a policy mix for renewable energies. Our goal is...

This policy note investigates whether the current level of public support to environment-friendly technologies is sufficient to allow European countries to respond to the multiple challenges posed by climate change and other environmental concerns. We first lay out the justifications for...

Germany changed renewable remuneration for wind power from a fixed Feed-In Tariff (FIT) to a floating Market Premium Scheme (MPS) in 2012. One aim of this adjustment was to better align the supply of generated wind electricity with the demand for it, e.g. through more system-friendly wind...

Up until now, wind turbines have been designed to generate electricity at the lowest possible total cost, independent of this electricity's market value. With an increasing penetration of wind power in the system, the market value of electricity generated by wind turbines is declining, since...

Bisher wurden Windkraftanlagen so ausgelegt, dass sie Strom zu möglichst geringen Gesamtkosten erzeugen, unabhängig vom Marktwert dieses Stroms. Mit steigenden Anteilen der Windenergie im Stromsystem fällt der Marktwert von Strom aus Windkraftanlagen, da sie tendenziell zur gleichen Zeit...
