中国石化新闻网讯 据油气新闻网11月7日报道， 国际可再生能源机构(Irena)表示，各国的目标是到2030年可再生能源装机发电量达到5.4太瓦，这只是所需10.8太瓦装机发电量的一半。
Irena在联合国气候变化大会COP27上发布的《2022年可再生能源目标：设计指南》称，要实现净零排放，到2030年可再生能源的目标发电能力必须是目前目标的两倍。
该报告评估了各国气候承诺中可再生能源的目标水平，并以将全球气温上升限制在1.5°C的气候目标作为基准。
其清楚地表明，尽管《格拉斯哥气候公约》提高了各国2030年目标的承诺，但迄今为止，集体层面的能源转型目标水平是不够的。
缩小差距
Irena总干事Francesco La Camera表示，在我们迫切需要看到快速实施的时刻，我呼吁世界领导人紧急缩小可再生能源部署差距，以追求弹性、能源安全和包容性经济。Irena的报告是对国际社会的一个警告，告诉他们可再生能源提供了一个容易实现的气候解决方案，但需要立即采取行动。气候承诺必须增强以释放可再生能源全部和未开发潜力的雄心。并补充道，我们需要真正的紧迫感。尽管取得了一些进展，但能源转型远未走上正轨。近期行动的任何不足都将进一步降低将温度控制在1.5°C的可能性。根据COP27的口号“共同实施”，我们必须从承诺转向具体的解决方案，以造福当地的人民和社区。
Irena的《世界能源转型展望》认为，到2050年，一半的能源消耗来自电力。90%的脱碳将涉及可再生能源，通过直接提供低成本电力、提高效率、电气化、可持续生物能源和绿色氢气。然而，实现2050年的气候目标将取决于到2030年采取充分的行动。
易于实现
Irena的报告发现，这在今天是很容易实现的，因为目前的可再生能源目标落后于最近的部署水平。要到2030年实现目前的目标，各国需要增加2.3太瓦的发电能力，相当于在未来9年平均每年增加259吉瓦。
这低于过去两年增加的实际装机发电量：在2020年和2021，尽管疫情和随后的供应链中断导致了问题的复杂性，但世界每年增加了近261吉瓦。
此外，到2030年的可再生能源电力目标仍然集中在全球几个地区。亚洲占全球目标产能的一半，其次是欧洲和北美。相比之下，中东和北非仅占2030年全球部署目标的3%，尽管该地区的潜力巨大。到2030年，撒哈拉以南非洲仅占全球总量的2%以上。
G20的成员
部署目标最高的国家都是G20的成员，几乎占全球总目标的90%。尽管他们在过去的可再生能源部署中所占比例很小，但最不发达国家（LDC）和小岛屿发展中国家（SIDS）的综合目标将使他们目前的可再生能源能力翻番。
Irena的分析建立在联合国气候变化组织最近发布的《2022年国家自主贡献综合报告》的基础上，该报告显示，气候计划仍不足以在本世纪末将全球气温上升限制在1.5摄氏度以内。
可再生能源是能源转型的支柱，也是可行的气候解决方案。然而，在《巴黎协定》183个国家自主承诺(NDC)中包含可再生能源内容的缔约方中，只有143个缔约方制定了量化目标，其中绝大多数侧重于电力部门。只有12个国家承诺将可再生能源占其总能源组合的一定比例。

Huge renewable energy potential remains untapped: Irena
Countries are targeting 5.4 terawatts (TW) of installed renewable power capacity by 2030, which would>To achieve net zero, the targeted renewable power capacity by 2030 would have to double compared to the level of ambition in current targets, said Renewable Energy Targets in 2022: A guide to design, released by Irena at the UN Climate Change Conference COP27.
The report assesses the level of renewable energy ambition in national climate pledges and benchmarks targets against the global climate goal of limiting temperature rise to 1.5°C.
It clearly shows the collective level of energy transition ambition to date is not enough despite the Glasgow Climate Pact to upgrade 2030 targets in national pledges.
Closing the gap
Irena’s Director-General Francesco La Camera said: “At a time when we desperately need to see rapid implementation, I call>“There is a need for real urgency.

However, achieving the 2050 climate target will depend>Readily achievable
This is readily achievable today as current renewable power targets lag recent deployment levels, Irena’s report finds. To achieve current targets by 2030, countries would need to add 2.3 TW of capacity, equivalent to average yearly additions of 259 gigawatts (GW) in the next nine years.
This is below the actual installed capacity added in the past two years: in 2020 and 2021, despite the complications that resulted from the pandemic and consequent supply chain disruptions, the world added almost 261 GW each year.
Furthermore, renewable power targeted by 2030 remains concentrated in a few regions globally. Asia makes up half of the global targeted capacity, followed by Europe and North America. In comparison, the Middle East and North Africa account for just 3% of global deployment targets for 2030, despite the region’s high potential. And Sub-Saharan Africa accounts for just over 2% of total global for 2030.
Part of G20
The countries targeting the highest level of deployment are all part of the G20, making up almost 90 per cent of the global aggregated target. Although they make up a small share of past renewable deployment, aggregated targets by least developed countries (LDCs) and small island developing states (SIDS) would double their current renewable capacity.
Irena’s analysis build>Renewables are the backbone of the energy transition and a viable climate solution. Yet out of the 183 parties to the Paris Agreement with renewable energy components in their Nationally Determined Commitments (NDCs), only 143 have quantified targets with the vast majority focusing on the power sector. only 12 countries had committed to a percentage of renewables in their overall energy mixes.
