BREAKING | #Wind & #Solar hit a record TENTH of global electricity in 2021.

But the global electricity transition needs to sustain high growth rates to replace coal & reduce emissions.

⚡️10 Tweet Thread of the Global Power Sector in 2021

We analysed annual power generation data for 209 countries from 2000 to 2020, with 2021 data included for 75 countries representing 93% of global power demand.

What did we find? #Wind and #solar took off!

[2/10] #GER22
ember-climate.org/insights/resea…
50 countries have now crossed the 10% #wind and #solar landmark, with 7 new countries in 2021 hitting the milestone for the first time: 🇨🇳🇯🇵🇲🇳🇻🇳🇦🇷🇭🇺🇸🇻

[3/10] #GER22

3 countries switched over 8% of their total electricity demand to #wind and #solar, which directly replaced #fossilfuels.

Wind & solar:
🇳🇱 - ⬆️ 11% in 2 years
🇦🇺 - ⬆️ 9%
🇻🇳 - ⬆️ 8%

Fossil fuels:
🇳🇱 - ⬇️ 15%
🇦🇺 - ⬇️ 9%
🇻🇳 - ⬇️ 10%

Viet Nam saw astonishing growth in #solar as it increased generation by 337% (+17 TWh) in a year, to become the world’s 10th largest solar generator.

Even as demand grew, Viet Nam reduced its #fossilfuel share & drove emissions down by 6%.

[5/10] #GER22

However, we also found that electricity demand rebounded, leading to a record rise in #CO2 and #coal.

Coal power rose 9% in 2021 to 10,042 TWh, the biggest percentage rise on record since at least 1985.

All-time #coal power records were set in China and India in 2021, and also in other Asian countries: 🇰🇿🇲🇳🇵🇰🇵🇭🇮🇩

[7/10] #GER22
ember-climate.org/insights/resea…
Record rise in #coal + modest rise in #gas means power sector emissions rose by 7% (778 million tonnes) in 2021, the largest absolute rise ever.

To reach @IEA 1.5 degrees pathway, power sector emissions need to fall 60% from 2021 to 2030.

[8/10] #GER22
ember-climate.org/insights/resea…
Leaders in #wind and #solar show that huge growth is realistic and can happen relatively quickly.

But shifts aren’t happening fast enough across all countries. Wind and solar need to sustain high growth rates for 1.5 degrees.

[9/10] #GER22
ember-climate.org/insights/resea…
To be on a pathway that keeps global heating to 1.5 degrees, #wind and #solar needs to sustain high growth rates of 20% every year to 2030.

⚡️ 10 Tweet Thread - Global Power Sector in 2020

What happened in 2020?
⏸️Pandemic paused electricity demand growth
⏩Wind and solar grew +315 TWh (+15%)
⏪Replacing coal generation -346 TWh (-4%)

[1/10] Ember's #GER21 Report
ember-climate.org/global-electri…
Growth in #wind and #solar helped drive global #coal power to a record fall of 4%.

Except in China. Despite impressive wind & solar growth, this didn’t keep up with electricity demand, so coal rose to fill the gap.

[2/10] #GER21
ember-climate.org/global-electri…
Almost a TENTH of global electricity in 2020 was supplied by wind turbines and solar panels.

Impressively, it has doubled since 2015, from 4.6% to 9.4%.

Most G20 countries are on the same journey, around the global average 🇮🇳🇨🇳🇯🇵🇧🇷🇺🇸🇹🇷

🇪🇺 10 Tweet Thread of the EU Power Sector in 2020

Key findings of our fifth annual report with @AgoraEW

1. Renewables overtook fossil fuels as the EU’s main source of electricity in 2020.

ember-climate.org/project/eu-pow…
2. Renewables generated 38% of Europe’s electricity in 2020, overtaking fossil fuels (37%). Nuclear power generated 25% of EU-27 electricity.

This green milestone was also reached in Spain and Germany in 2020.

EU Power Sector in 2020: ember-climate.org/project/eu-pow…
3. This transformation has been driven by rapid growth in #wind and #solar power generation, which have almost doubled since 2015 to deliver 1/5 of EU electricity in 2020.

In the last 30 days, Europe's electricity sector CO2 emissions have collapsed by 39%.

This is giving valuable lessons on how to run a fossil-free electricity grid.

What are these lessons?
THREAD: 1/11
2/11 The lights have stayed on! The electricity system is robust: no excuse to slow wind+solar investment.

That's despite a 42% fall in Europe's coal gen & 30% fall in gas gen (chart).

Read EU's security briefing: ec.europa.eu/info/news/focu…

@ENTSO_E's summer outlook out end-May
3/11 But record negative prices show there are supply/demand inflexibilities.

Common in Germany+Denmark+UK for a while, but now increasingly common in Belgium, Czechia, Finland, France, Ireland, Netherlands...
