As the world faces the mounting challenges of climate change, the urgency to transition from fossil fuels to clean, sustainable energy sources has never been more critical. The key to this transformation may lie with the G20 nations. Representing around 85% of global GDP and nearly 67% of the world’s population, these 20 countries have the land, infrastructure, and financial power to lead the charge in global renewable energy development. The G20 nations are made up of: Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Republic of Korea, Mexico, Russia, Saudi Arabia, South Africa, Türkiye, United Kingdom, and United States, the European Union and the African Union.
Recent studies suggest that the above mentioned nations alone could generate enough green energy to power the entire planet by 2050. This blog explores how that is possible and why it matters for CA Mining and CA Energy, as players in the sectors driving and supporting global energy and industrial infrastructure.
Solar and Wind Potential Across the G20
According to recent research, G20 countries collectively possess:
- 33.6 million km² of land viable for solar farm installations
- 31.1 million km² suitable for wind energy development
If just 2% of that combined land area were utilised for solar and wind energy infrastructure, it would be enough to meet global electricity demand. In fact:
- Solar alone could provide 37 times the world’s current electricity demand
- Wind energy could contribute 18 times the global need
Combined, solar and wind potential in these nations exceeds global energy demand by more than 50 times.
From Emissions Leaders to Clean Energy Champions
Historically, the G20 countries have contributed significantly to the climate crisis, producing about 87% of global energy-related CO₂ emissions. However, they are also at the forefront of renewable energy development, accounting for 81% of the world’s installed renewable capacity and 75% of global potential for future deployment.
This positions the G20 as both responsible for past emissions and uniquely capable of leading the clean energy revolution.
Some Country Spotlights
Several G20 nations have already made substantial progress toward green energy adoption:
- China added over 373 GW of renewables in 2024, nearing a total of 1,878 GW. The country aims to reach 80% non-fossil energy by 2060.
- India ranks third globally in renewable energy capacity. Approximately 46% of its installed energy mix (~203 GW) is now renewable, with a target of 500 GW by 2030.
- Germany has transitioned over half (52.4%) of its electricity generation to renewable sources, showcasing the success of its Energiewende program.
- Pakistan recently sourced 25.3% of its monthly electricity from solar energy, thanks to large-scale panel imports.
- Australia, Canada, and the UK have also announced ambitious clean energy targets, with several aiming for 100% renewable electricity by 2035.
These countries demonstrate that the shift to renewable energy is actively and rapidly happening.
A Strategic Transition from Closed Coal Mines to Soler Farms
One compelling opportunity for G20 countries is the transformation of closed coal mines into renewable energy hubs. Studies show that converting just over 300 decommissioned surface coal mines into solar farms could generate up to 300 GW of clean electricity by 2030.
This strategy not only recycles industrial land but also provides jobs and helps communities pivot from carbon-intensive industries to future-proof, green economies.
Three Pillars of the Renewable Transition
1. Financial Investment
G20 countries invested over US $424 billion in clean energy between 2020 and 2021. However, fossil fuel subsidies still surpassed this amount, totaling $471 billion in the same period. To unlock the full potential of renewable energy, these subsidies must be redirected to green projects, especially in developing economies that are currently underfunded.
2. Policy and Regulation
Setting ambitious goals is not enough. Binding policy frameworks are needed to support rapid scaling of renewables, including goals to achieve 70% renewable electricity by 2030, 60% renewable final energy by 2030 and setting concrete policies for heating, transport, storage, and public infrastructure energy supply.
3. Equity and Inclusion
Emerging economies like Brazil, South Africa, and India must be included in the energy transition. While Africa holds some of the greatest renewable potential, it currently receives less than 2% of global clean energy investment. The G20 must lead by example and invest in equitable, cross-border energy development strategies.
Future Path to 2050
If current trends continue, G20 energy-related emissions could double by 2050. However, if bold policies and investments are implemented now, these emissions could be reduced to just 42% of 2020 levels. The pathway to a net-zero world depends heavily on the actions of these nations.

Overcoming Challenges
While the potential is vast, key challenges remain:
- Grid Infrastructure: Many G20 nations need large-scale investments in grid upgrades, storage, and distribution.
- Finance Gaps: Public-private partnerships and new financial models are needed to scale renewable projects.
- Geopolitical Risks: The global fossil fuel market remains deeply entrenched in many economies. Strong governance and international collaboration are vital.
The G20 countries have both the resources and responsibility to reshape the global energy landscape. With vast solar and wind potential, these nations can realistically supply enough renewable energy to meet global demand many times over.
