One of the European Union's (EU) membership conditions includes an ambitious energy policy objective such as energy security, environmental protection and diversification using renewables. However, the impact of the energy policy on environmental sustainability is yet to be assessed. In line...

The purpose of this paper is to demonstrate that an imperative demand for an existence in harmony with Nature is created when the costs incurred for such an existence can be deducted from taxable income. All reasonable consumers who pay income taxes will then be driven to buy tax-deductible...

In Germany, the large growth in renewable power generation (RPG) capacities in the past has been mainly due to demand supporting policy measures (demand pull). Globally, increasing deployment also is accelerated by strongly decreasing costs of these technologies. Deployment, on the other hand...

The transition to a future electricity system based primarily on wind and solar PV is examined for all regions in the contiguous US. We present optimized pathways for the build-up of wind and solar power for least backup energy needs as well as for least cost obtained with a simplified,...

This paper presents a new approach to modeling the variability of power generation from a renewable source such as wind or flowing water. The force of the power generating agent is assumed to change according to a semi-Markov process with finite state space. For the purpose of its construction,...

To analyze the challenge of large-scale integration of renewables during the next decades, we present a conceptual power system model that bridges the gap between long term investment allocation and short-term system operation decisions. It integrates dynamic investments in generation,...
