Germany s renewable energy storage ratio
The transport sector holds the lowest share of renewable energy sources. In 2000 less than one percent of final energy consumption for transport purposes was derived from renewable energy sources. Thi. [pdf]
Competition in electricity markets with renewable energy sources
Abstract This paper studies the effects of the diversification of energy portfolios on the merit order effect in an oligopolistic energy market. The merit order effect describes the negative impact of renewable energy, typically supplied at the low marginal cost, to the. . The merit order scribes the negative impact of renewable energy, typically supplied marginal cost, to the electricity market. [pdf]
