The main aim of this paper is to observe the environmental behaviour in some cities of the word, by analyzing for each city the trends of several energy and emissions indicators that appear as explanatory variables in both energy and labour average productivity equations. At the same time we...

I examine the effects of increasing amounts of fluctuating renewable energy on residual load, which is defined as the difference between actual power demand and the feed-in of non-dispatchable and inflexible generators. I draw on policy-relevant scenarios for Germany and make use of extensive...

The emerging literature on power markets with high shares of fluctuating renewables suggests that more frequent start-up procedures of thermal power plants may become an increasing concern, both for costs and possibly also for market design. Based on official scenario assumptions, we investigate...

We examine the effects of future renewable expansion in Germany on residual load and renewable surplus generation for policy-relevant scenarios for 2022, 2032 and 2050. We also determine the storage capacities required for taking up renewable surpluses for varying levels of accepted curtailment....

In its Green Paper on a 2030 framework for climate and energy policies, the European Commission calls for a framework for the future development of environment and energy policy beyond 2020. However, much like the Energy Roadmap 2050 adopted by the Commission in December 2011, the Green Paper is...

The daily average price of electricity represents the price of electricity to be delivered over the full next day and serves as a key reference price in the electricity market. It is an aggregate that equals the average of hourly prices for delivery during each of the 24 individual hours. This...

The significance of natural gas is on the rise due to the restructuring and decarbonization of energy systems worldwide. Natural gas is widely available and flexible as it can be used in electricity generation, manufacturing, transport, and private households. Compared to other fossil fuels,...

This paper evaluates the predictability of WTI light sweet crude oil futures by using the variance risk premium, i.e. the difference between model-free measures of implied and realized volatilities. Additional regressors known for their ability to explain crude oil futures prices are also...

In this paper we investigate the time-varying relationship between oil and natural gas in the UK. We develop a model where relative prices can move between pricing-regimes; markets switch between being decoupled and integrated. Our model endogenously accounts for periods where oil and natural...

Die Europäische Kommission hat im Januar 2014 einen Rahmen für die Klima- und Energiepolitik bis 2030 vorgeschlagen. Er enthält Ziele zur Reduktion von Treibhausgasen und zur Nutzung erneuerbarer Energien, aber kein konkretes Ziel für die Steigerung der Energieeffizienz. Die...
