Few studies have investigated and compared the acceptance of different energy technologies. Moreover, little is known about the role of protected values. These are the values that a person considers extremely important and non-negotiable – for example in the context of energy resources.
In a large survey in Switzerland, Vivianne H. M.
Central heating systems are widely used in homes throughout much of Europe. Most of them consist of one or more centrally located pumps that circulate hot water to the radiators and the floor heating system. However, there are alternatives available as well. A relatively new technology uses small decentralized circulation pumps. Each radiator and each circuit of the floor heating system has its own circulation pump. This not only enables zone-heating, it also helps save fuel and electricity.
How do we define the term ‘sustainable energy’? Will our definition be helped or hindered if instead of calling an energy source either sustainable or unsustainable, we talk about degrees of sustainability? And do we focus too much on the economic and environmental aspects of sustainability, and forget the social dimension?
What is sustainable energy?
Asking this question – whether on a street corner or to a panel of experts – will invariably lead to a variety of answers and opinions.
Long-term energy forecasts have a poor track record. They have failed to accurately predict total energy demand, sector demand and energy prices. Attempts to improve accuracy by adding more factors to explain consumption and pricing has complicated the models without necessarily improving their results. This last of 3 articles on long-term energy forecasting focuses on why long-term energy forecasting is so difficult, ideas to improve it and suggested alternatives.
The Track Record is Poor for Predicting Long-Ter
Since the 1970’s much work has been done developing and improving long-term energy forecasting methods. Forecasters typically use 1 of 5 methods or a combination of these: trend projections, econometric analysis, scenario analysis, end-use analysis and systems dynamics. This article discusses each of these methods, their pros and cons, and their suitability for different purposes. This is the second of a 3-part series on long-term energy forecasts. The first installment discussed the necessity and value o
