可再生水电是一种可靠的能源, versatile and low cost source of clean electricity generation and responsible water management.
Modern hydropower plants are helping to accelerate the clean energy transition, 提供必要的权力, 存储, 灵活性和气候缓解服务.
水电也是一项重要的建筑资产 安全、清洁的电力系统 并达到全球 零 目标.
更多的情况说明:
有 四个主要类型 水力发电厂:流水，储存， 抽水蓄能 和海外水电.
Only a small minority of the world's dams are built for hydropower, 与大多数用于灌溉, 水的供应, 防洪及其他用途.
Many hydropower dams are used for multiple purposes beyond electricity generation, providing infrastructure to supply clean water for homes, 工业和农业, 还有娱乐和交通服务.
Hydropower projects can be used to regulate and store water to mitigate the impacts of extreme weather events such as floods and drought, 哪些是由于气候变化而上升的. 更多的.
周围 占所有可再生能源电力的60% 由水力发电. 该部门的产量约为 占总发电量的16% 从所有来源.
在其 2021年水电特别市场报告, the International 能源 Agency (国际能源机构) reports that hydropower accounts for nearly a third of the world’s capacity for flexible electricity supply 并且有潜力提供更多.
No country has come close to achieving 100% renewables without hydropower in the energy mix.
Hydropower installed capacity reached 1,330 gigawatts (GW) in 2020 as generation hit a record 4,370 terawatt hours (TWh). China, Brazil, the USA, Canada and India are the largest 水电专业ducers by installed capacity.
China, Brazil, the USA, Canada and India are the largest 水电专业ducers by installed capacity. 更多的.
2015 - 2019年, the average year-on-year worldwide growth in hydropower installed capacity was 2.1%.
Hydropower is an ideal complement to variable renewables like wind and solar, thanks to its flexibility and energy 存储 services.
Hydropower can meet demand when these intermittent sources are unavailable. 抽水蓄能水电站, operating like a green, rechargeable battery, absorbs energy when supply exceeds demand.
水电就是其中之一。 最清洁的电力来源, with a low greenhouse gas emission intensity compared to other energy forms.
独立的 研究 suggests that use of hydropower instead of fossil fuels for electricity generation has helped to avoid more than 100 billion tonnes of carbon dioxide in the past 50 years alone, exceeding even the emissions averted by nuclear power. That’s roughly equivalent to the total annual carbon footprint of the United States for 20 years.
Over the life cycle of a power plant, hydropower offers some of the 温室气体排放量最低 每单位产生的能量-以及倍数 环境效益. (国际能源署水电特别市场报告2021年)
IHA估计，如果水力发电被煤炭取代 高达40亿吨 of additional greenhouse gases would be emitted annually, increasing global emissions from fossil fuels and 行业 by 10 per cent. 的re would also be 150 million more tonnes of air polluting particulates emitted each year.
根据 国际可再生能源署, the world’s existing hydropower capacity will need to grow by around 到2050年达到60% to reach 2,150 GW to help limit the rise in global temperature to well below two degrees Celsius.
的 国际能源机构 有报道称, 新增水电装机容量1300吉瓦 is required in order to keep temperature rises to within a 1.5度的目标.
这样的增长将有助于产生一些 600000年技术工作 over the coming decade and would require an estimated investment of US$1.7万亿年.
Global investment in hydropower topped US$50billion in 2019 according to the International 能源 Agency (国际能源机构), 远低于 估计每年需要1000亿美元 帮助满足组织的要求 可持续线上正规的买球网站情况.
Hydropower provides very low cost electricity over its long lifetime, despite relatively high upfront construction costs.
的 global weighted average cost of electricity from 水电专业jects in 2018 was US$0.047每千瓦时, making it the lowest-cost source of electricity in many markets (IRENA).
Hydropower provides an opportunity to generate significant revenue from exports to neighbouring countries. In addition, the hydropower 行业 directly employs around 全世界有200万人，以及更多的互联供应链(IRENA)
Hydropower projects of all sizes can result in net-benefits to communities and the environment, provided they have a strategic fit in a river basin and are responsibly developed and operated.
水电可持续性工具 exist to ensure that projects can be developed and operated in accordance with good practice. 的se guidelines and assessment tools cover 26 environmental, 社会和治理绩效标准.
由一个 多方利益相关者群体 公民社会的, 行业, 政府和金融机构, the tools are aligned with safeguards developed by the World Bank and other organisations. 更多的.
Sustainable hydropower supports the achievement of the United Nations Agenda for Sustainable Development, 以及关于气候变化的《网上正规买球网站》.
的 17个可持续线上正规的买球网站目标 were adopted by all member governments of the United Nations and provide a blueprint of priorities for national governments, 多边组织, 商业和民间社会.
当负责地开发和操作, 水电专业jects can directly support the achievement of SDGs 6, 7, 9和13:
目标6: Ensuring availability and sustainable management of water for all
目标7: Providing access to affordable, reliable, sustainable and modern energy for all
目标9: Upgrading infrastructure with clean, environmentally sound technologies
目标13: Taking action to combat climate change and its impacts
