CHANG Youngho, Benjamin TANG, HUM Wei Mei, "Energy and Economy Modelling”, 31 March 2009
For a long time, energy has been nested within capital in economic analyses in the general form Q = Q (K, L), where K and L are capital and labour respectively. After the two oil shocks in the 1970s, the limit of energy resources is recognised, and energy is treated as a third production factor. Traditionally, there are two approaches to energy modelling: the top-down economic approach, and the bottom-up technological method. More recent models synthesise both approaches to produce a more rigorous mathematical solution. This article discusses the salient aspects of popular models such as the Markal- Macro (MM), the Emissions Prediction and Policy Analysis (EPPA) model, Asia-Pacific Integrated Model (AIM), and the Long-range Energy Alternatives Planning (LEAP) model. |
| ANG Beng Wah, ZHOU Peng, "Tracking Economy-Wide Energy Efficiency”, 31 December 2008
Energy efficiency improvement has become a vital part of national energy strategies, and national and international initiatives on climate change. But what does "energy efficiency" truly mean, and how can it be tracked economy-wide? This article briefly discusses various definitions of energy efficiency. It also describes how an economy-wide energy efficiency index is constructed from the estimated energy intensity effects at a lower level. |
