Future of Renewable Energy: Five Key Developments
Solar is becoming a dominant global power source
Solar’s rapid expansion has defied earlier projections and is now overtaking nuclear generation. Long-term scenarios suggest solar could eventually provide about 60% of energy in a fully renewable system, with wind contributing roughly 30%.

Non-fossil power—including renewables and nuclear—is projected to overtake fossil-fuel electricity generation by 2030. Renewables alone could become the world’s primary power source by 2035.

Despite solar and wind’s momentum, hydropower is expected to remain a leading renewable source in the near term. Expansion is being driven largely by China, India and Brazil, with major projects also advancing in Ethiopia.

A typical AI data centre can consume as much electricity as 100,000 homes. The United Nations is urging major technology companies to power data centres entirely with renewables by 2030, making clean-energy procurement and grid expansion increasingly urgent.

The clean-energy shift could create 14 million jobs by 2030 while displacing about 5 million fossil-fuel roles, for a net gain of 9 million. However, grid upgrades, storage, fuel-distribution infrastructure and the limited maturity of emerging technologies remain major constraints.

Why It Matters
Renewable energy is moving from an alternative source to the backbone of the global electricity system. Falling costs could help developing economies meet rising demand without locking
