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
The 21st century has seen the rise of the two largest emerging economies: China and India. In fact, China’s economy is now the world’s largest. As these countries’ industries expand and their citizens enjoy higher standards of living, their demand for energy will increase. The economic emergence of other nations and their need for energy should also be expected, especially in Africa and Asia. Accommodating the world’s growing need for energy will be challenging and require long-term ener
The UK government is guaranteeing the purchase of power from a 3340 MW nuclear plant at €110 per MWh for 35 years. Now they are looking for developers to build further nuclear plants. Does this make any sense?
The public trust in nuclear power is strong in Britain. All three major political parties back nuclear generation. When public support for nuclear crashed across Europe and the world following Fukushima, in Britain it remained robust. In Japan, just 2% want an expansion of nuclear generation.
