到2050年能源效率将占最大的投资份额

据土耳其新闻社5月19日消息称，国际可再生能源机构(IRENA)周五发布的报告显示，可再生能源和能源效率是实现全球能源转型的两个关键解决方案。

根据IRENA的《全球可再生能源展望:2050年能源转型报告》，与能源相关的二氧化碳排放在过去十年中以每年1%的速度增长。

IRENA认为，现在是时候投资数万亿美元了，不是投资化石燃料，而是投资可持续能源基础设施，以应对气候变化，并成功过渡到可再生能源，提高生活质量。

该机构的报告详细描述了其基于能源转型方案(TES)中更深层次的碳化的预测，估计可再生能源和能源效率加在一起可以提供减少能源相关排放所需的90%以上的缓解措施。

“更深入的脱碳前景”方案被认为是一个雄心勃勃，乐观而现实的能源转换途径，主要基于可再生能源。

根据2016年至2050年TES中的这一观点，在130万亿美元的总投资中，将为能效项目指定更多的43万亿美元投资，以实现净零排放。

报告指出:“这将使能源系统走上正轨，使本世纪全球气温上升幅度保持在远低于2摄氏度和接近1.5摄氏度的水平。”

报告强调:“尽管健康冲击和油价暴跌可能会在2020年抑制排放，但反弹将恢复长期趋势。”

Energy efficiency to take most investment share by 2050

Renewable energy and energy efficiency are the two key solutions to enable global energy transformation, the recent International Renewable Energy Agency's (IRENA) report showed on Friday.

According to the IRENA's Global Renewables Outlook: Energy Transformation 2050 report, energy-related CO2 emissions have risen by 1% per year over the past decade.

IRENA suggests that the time has come to invest trillions, not in fossil fuels, but in sustainable energy infrastructure to combat climate change and for the successful transition to renewables to enhance life quality.

The agency’s report which details its projections based on deeper carbonization in its Transforming Energy Scenario (TES), estimates that renewable energy and energy efficiency together can offer over 90% of the mitigation measures needed to reduce energy-related emissions.

The Deeper Decarbonization Perspective scenario, which is considered an ambitious, optimistic, and realistic energy transformation pathway, is based largely on renewable energy sources.

As per this perspective in the TES between 2016 and 2050, energy efficiency projects will be designated more investments of $43 trillion out of total investments of $130 trillion to move towards achieving net-zero emissions.

"This would set the energy system on the path needed to keep the rise in global temperatures to well below 2 degrees Celsius and towards 1.5 degrees Celsius during this century," the report indicates.

"While the health shock and oil slump may suppress emissions in 2020, a rebound would restore the long-term trend," the report highlighted.
