RESEARCH SUMMARY AND KEY TAKEAWAYS

The global alternative energy market is reaching a critical transformation point. In 2025, the renewable energy market is valued at $1.74 trillion and is projected to reach $7.28 trillion by 2034 at an average annual growth rate (CAGR) of 17.23%. This means more than a fourfold expansion in nine years — the fastest growth in the history of the energy sector.

The key takeaway: solar energy (80% of new capacity) and wind power (14-16%) hold leading positions, while hydropower, geothermal energy, and hydrogen occupy specialized but growing niches. For BRICS companies and investors, this opens unprecedented opportunities in manufacturing, integration, and financing of energy projects.

Solar energy is the fastest-growing electricity source in human history. It took only 8 years to scale from 100 TWh/year to 1,000 TWh/year — faster than wind (12 years), gas (28 years), or coal (32 years).

Current indicators (2025):

• Global capacity: ~1,500 GW (growing 32-35% per year)
• 2030 forecast: 2,200+ GW (80% of global expansion)
• Manufacturing: China provides 80% of global panel production
• Cost: <$0.70 per watt (down 90% over 10 years)

New technologies with high commercial readiness:

Perovskite solar cells (PCS):
