The increased use of renewable energy is critical to reducing emissions of greenhouse gases in order to limit climatic change. Hydropower is currently the major renewable source contributing to electricity supply, and its future contribution is anticipated to increase significantly. However, the successful expansion of hydropower is dependent on the availability of the resource and the perceptions of those financing it. Global warming and changes in precipitation patterns will alter the timing and magnitude of river flows. This will affect the ability of hydropower stations to harness the resource, and may reduce production, implying lower revenues and poorer returns. Electricity industry liberalisation implies that, increasingly, commercial considerations will drive investment decision-making. As such, investors will be concerned with processes, such as climatic change, that have the potential to alter investment performance. This paper examines the potential impact of climatic change on hydropower investment. It introduces a methodology for quantifying changes in investment performance, and presents preliminary results from a case study. These inform discussion of the implications for future hydropower provision and our ability to limit the extent of climatic change. of increase is accelerating. The rise in temperature is expected to be accompanied by increases in global mean precipitation levels of up to 15% (Houghton et al., 1990). Figure 1. Historic and future temperature rise (adapted from Houghton et al., 1990) Many predictions of future climate are based on the output of complex numerical General Circulation Models (GCMs) which simulate physical processes in the atmosphere and oceans. Although GCMs differ in the detail of their methodologies, most agree on the general temperature trend (Gates et al. 1990, Wood et al. 1997). There are many potential impacts of climatic change including: loss of land due to sea level rise, damage from increased levels of storm activity, and threats to bio-diversity (Houghton et al., 1990). Under the Kyoto Protocol (UNFCCC, 1998) most countries agreed that they would limit greenhouse gas emissions. As electricity production accounts for a significant portion of the emissions, much of the burden will fall on this sector. Increased use of renewable energy sources, including hydropower, is one suggested way in which the emissions targets can be met. Unfortunately, the very fact that renewable energy resources harness the natural climate means that they are at risk from changes in climatic patterns. As such, changes in climate due to higher greenhouse concentrations may frustrate efforts to limit the extent of future climatic changes.
增加可再生能源的使用对于减少温室气体排放以限制气候变化至关重要。水电目前是电力供应的主要可再生能源，预计其未来的贡献将显著增加。然而，水力发电的成功扩展取决于资源的可得性和那些为其提供资金的人的看法。全球变暖和降水模式的变化将改变河流流量的时间和大小。这将影响水电站利用资源的能力，并可能减少产量，意味着收入减少和回报减少。电力行业自由化意味着，商业考虑将越来越多地推动投资决策。因此，投资者将关注气候变化等有可能改变投资业绩的过程。本文探讨了气候变化对水电投资的潜在影响。它介绍了一种量化投资业绩变化的方法，并提出了一个案例研究的初步结果。这些为讨论未来水电供应的影响以及我们限制气候变化程度的能力提供了信息。增长正在加速。气温上升预计将伴随全球平均降水量增加15% (Houghton et al.， 1990)。图1所示。历史和未来的温度上升(改编自Houghton等人，1990年)对未来气候的许多预测都是基于模拟大气和海洋物理过程的复杂数值一般环流模式(GCMs)的输出。虽然gcm在其方法的细节上有所不同，但大多数gcm对总体温度趋势的看法是一致的(Gates et al. 1990, Wood et al. 1997)。气候变化有许多潜在的影响，包括:海平面上升造成的土地流失、风暴活动增加造成的破坏以及对生物多样性的威胁(Houghton et al.， 1990)。根据《京都议定书》(UNFCCC, 1998)，大多数国家同意限制温室气体排放。由于电力生产占排放量的很大一部分，因此大部分负担将落在该部门身上。增加使用包括水电在内的可再生能源是实现排放目标的一种建议方法。不幸的是，可再生能源利用自然气候这一事实本身就意味着它们面临气候模式变化的风险。因此，温室气体浓度升高导致的气候变化可能会阻碍限制未来气候变化程度的努力。
