An increasing number of retail energy markets exhibit price fluctuations and provide home users the opportunity to buy energy at lower than average prices. However, such cost savings are hard to realize in practice because they require human users to observe the price fluctuations and shift their electricity demand to low price periods. We propose to temporarily store energy of low price period...

Land can be used in several ways to mitigate climate change, but especially under changing environmental conditions there may be implications for food prices. Using an integrated global system model, we explore the roles that these land-use options can play in a global mitigation strategy to stabilize Earth's average temperature within 2 °C of the preindustrial level and their impacts on agricu...

Can negative electricity prices encourage inefficient electrical energy storage devices? Edward Barbour, Grant Wilson, Peter Hall & Jonathan Radcliffe To cite this article: Edward Barbour, Grant Wilson, Peter Hall & Jonathan Radcliffe (2014) Can negative electricity prices encourage inefficient electrical energy storage devices?, International Journal of Environmental Studies, 71:6, 862-876, DO...

Crude oil accounts for the lion’s share of the demand for fossil fuels. Within the past few decades, increased oil consumption in a variety of economic sectors has lead to massive release of toxic pollutants and greenhouse gases, most specially Carbon Dioxide, as well as inflicting damages to the Earth like global warming and climate change. Accordingly, it is imperative to explore the relation...

in general, energy prices, such as those of crude oil, are affected by deterministic events such as seasonal changes as well as non-deterministic events such as geopolitical events. it is the non-deterministic events which cause the prices to vary randomly and makes price prediction a difficult task. one could argue that these random changes act like noise which effects the deterministic variat...

Many studies conclude that the rise in global food prices due to higher demand from the development of biofuels, climate anomalies, and increased of oil prices. Not only the food commodity index rose more than 60 percent, nonfood commodity price index also rose over 60 percent and crude oil price index has increased even further above 60 percent. The purpose of this study is to analyze the impa...

Based on a vector autoregressive model and dynamic conditional correlation generalized heteroskedasticity model, this study explores the relation between international crude oil market Chinese energy stock market. The findings suggest positive one-way spillover effect of returns China’s returns. Furthermore, two markets is time varying.

Strategic bidding in joint energy and spinning reserve markets is a challenging task from the viewpoint of generation companies (GenCos). In this paper, the interaction between energy and spinning reserve markets is modeled considering a joint probability density function for the prices of these markets. Considering pay-as-bid pricing mechanism, the bidding problem is formulated and solved as a...

Introduction World agriculture is at a turning point: economic growth, energy needs, and climate change redefine the equations of agricultural supply and demand and contribute to accelerate food prices. Biofuels have been particularly high on the global agenda largely due to rising concerns about national energy security, high energy prices, and global climate change, as well as the income expe...
