Abstract

In order to mitigate global climate change and air pollution, the Chinese government has assigned high priority to expanding low-carbon power generation in China. Recent studies have shown that wind power is one of the most promising renewable energy option in China. Although many studies have estimated the generation potential of onshore wind power, their results vary widely from 1783 TWh to 39,000 TWh. Therefore, we examine the different assumptions in these papers and identify three main factors influencing the results. The three influencing factors are: weather data set, land utilisation factor, and wind turbine configuration. For our model-based analysis, we define a reference scenario which is used to compare the results. Our analysis shows using a different weather data set increases the generation potential to roughly 35,000 TWh. This is 54% higher than the generation potential of the reference scenario. The land utilisation factor also has a large influence, ranging between −10% and −51%. The studies' assumptions and data should be subjected to careful scrutiny, as the calculated wind power potentials are widely used to develop decarbonisation strategies for the energy system. • Study results on wind power potentials in China vary from 1783 TWh to 39,000 TWh • Influencing factors: weather data set, land utilisation, and wind turbine configuration. • Model-based sensitivity analysis with nine scenario settings. • Chosen weather data set has the highest impact on the calculated results with a variation of 54%.

Abstract

This paper focuses on the climate change challenge faced by Central & Eastern European countries both those inside the European Union and those outside it. They have enormous energy intensity and associated greenhouse gas (GHG) emissions, mainly from energy production, which is oil, and worse, coal-fired power stations. As a group of blocs, CEE is a significant actor on the global climate change canvas. Their actions can make a difference. But there are numerous regulatory constraints that make this currently difficult. With the onset of a new global regime consequent on the renegotiation of acceptable levels of GHG emissions at Bali in 2007, to be ratified in Copenhagen in 2009, all countries with levels such a those in CEE will have to reduce emissions significantly as will countries throughout the world, especially the ‘big burners’ like USA and China. With some data and textured case illustrations the article points the way to mitigation of emissions by learning from Denmark, the world leader as a ‘green economy’ and Wales, part of the UK which has a long established heavy industry tradition comparable to many CEE countries and where positive change is underway from unlikely sources.
