| Summary/Abstract |
In the last quarter of the 20th century, many power companies used the integrated resource planning (IRP) approach in power expansion planning. Today, very few power companies use this approach because of the split between the power generation and distribution activities. It seems that, in some countries, long-term power system expansion planning has become a task of the central government. To help the government in this area, this paper proposes a new approach called the integrated resource strategic planning (IRSP). When combined with a smart grid, this approach can replace the IRP for the government's power sector expansion. This paper introduces the necessity and possibility of using this new approach, presents a framework on how to use the approach, and justifies the effectiveness of this approach against the traditional power planning approach, with a case study in China. This paper concludes that if China follows the IRSP approach, it may be able to avoid or postpone up to 69 GW of power generation in the period 2009-2015. These measures could help mitigate 201.8 million tons of carbon dioxide (CO2), 0.816 million tons of sulfur dioxide (SO2), and 0.946 million tons of nitrogen oxide (NOx).

| Summary/Abstract |
Emissions mitigation is a major challenge for China's sustainable development. We summarize China's successful experiences on energy efficiency in past 30 years as the contributions of Energy Usage Management and Integrated Resource Strategic Planning, which are essential for low-carbon economy. In an Economy-Energy-Electricity-Environment (E4) framework, the paper studies the low-carbon development of China and gives an outlook of China's economy growth, energy-electricity demand, renewable power generation and energy conservation and emissions mitigation until 2030. A business-as-usual scenario is projected as baseline for comparison while low carbon energy and electricity development path is studied. It is defined as low carbon energy/electricity when an economy body manages to realize its potential economic growth fueled by less energy/electricity consumption, which can be characterized by indexes of energy/electricity intensity and emissions per-unit of energy consumption (electricity generation). Results show that, with EUM, China, could save energy by 4.38 billion ton oil equivalences (toes) and reduce CO2 emission by 16.55 billion tons; with IRSP, China, could save energy by 1.5 Btoes and reduce CO2 emission by 5.7 Btons, during 2010-2030. To realize the massive potential, China has to reshape its economic structure and rely much on technology innovation in the future.
