SkyEdgeAI's comprehensive synthesis of publicly available data from IEA, IRENA, Ember, WEF, Science, Nature, and 40+ primary sources — covering every major energy sector from 2025 through outlook to 2030.
2025 was named Science magazine's Breakthrough of the Year: the seemingly unstoppable rise of renewable energy. Renewables surpassed coal as a source of global electricity for the first time across a sustained period. Solar and wind grew fast enough to cover all new global electricity demand in the first half of 2025.
Solar photovoltaics now leads every metric — capacity added, cost reduction, and speed of deployment. China manufactures 80% of the world's solar cells, driving prices to levels no competitor can match. 2025 was another record-breaking year.
Global onshore wind had a record year in 2025, while offshore wind experienced a painful slowdown driven by rising costs, cancelled projects, and geopolitical disruption — yet a record construction pipeline signals strong long-term momentum.
China accounts for ~50% of cumulative global offshore wind installations.
Nuclear energy is experiencing its strongest revival in decades, driven by soaring electricity demand from AI and data centres. Small Modular Reactors (SMRs) — factory-built, scalable, and deployable almost anywhere — are transitioning from laboratory concept to commercial pipeline with unprecedented speed and private investment.
Conventional geothermal is geographically limited — but Enhanced Geothermal Systems (EGS), using oil-and-gas drilling techniques to create artificial hydrothermal reservoirs anywhere on Earth, are transitioning from experiment to commercial deployment in 2025–2026. Investment surged 80% in a single year.
Fusion energy — the power source of the sun — has moved from theoretical aspiration to a competitive global industry. With $10.6 billion in private investment, 53 companies active, and governments racing to establish national strategies, commercialisation by the mid-2030s is a credible (if challenging) target.
Intermittency — the inability of solar and wind to generate power when the sun isn't shining or wind isn't blowing — has historically been the core limitation of renewables. A wave of storage technologies, from lithium-ion batteries to green hydrogen and next-generation chemistries, is systematically solving this problem.
Every solar panel, wind turbine, EV battery, and electrolyser requires specific minerals that are geographically concentrated, politically sensitive, and slow to bring to market. The clean energy transition is accelerating demand for these materials at a pace that supply chains — locked in decade-long development cycles — are struggling to match.
The Global South — Latin America, Africa, South Asia, Southeast Asia — holds 70% of the world's renewable energy potential and will drive 80% of future energy demand growth. Yet it received just 7% of global clean energy investment. The investment imbalance is the defining injustice — and the biggest opportunity — of the energy transition.
India achieved its 2030 target of 50% non-fossil electricity capacity in 2025 — five years early. It is now the world's fourth-largest renewable energy market, with solar capacity growing 42-fold since 2014, and a bold green hydrogen strategy that could reshape its industrial and import structure by 2030.
A sector-by-sector synthesis of every key metric, challenge, and forward projection from 2025–2026 through to 2030 and beyond.
| Sector | 2025–2026 Status | Key Figure | 2030 Outlook | Trend |
|---|---|---|---|---|
| Solar PV | 511–647 GW added in 2025; cumulative ~2,900 GW. Perovskite tandems at 34.6% efficiency entering commercial scale. | +11% YoY additions | Dominant technology; ~$3.6T market value by 2030. 35%+ efficiency cells commercial. | ▲ Accelerating |
| Onshore Wind | 158.7 GW total wind added. China added 119 GW alone (75% of world total). AI-optimised blades and smart grid integration advancing. | +14% YoY | China targets 100 GW/year wind 2026–2035. 20 MW+ turbines standard. | ▲ Strong |
| Offshore Wind | Only 6 GW added in 2025 (down 46% from 2024). Rising costs, US policy reversals. Floating wind proven but commercially challenging. | 84.5 GW total operational | 396 GW by 2034. Offshore to nearly triple 2024–2030 to ~238 GW. North Sea 300 GW target. | ~ Recovering |
| Nuclear — SMRs | 127+ designs globally. EU strategy adopted March 2026. US, UK, tech giants all signed major agreements. No commercial SMR yet in operation (except Russia, China pilots). | 400 GW US target by 2050 | First commercial SMRs operational early 2030s. Factory production to drive cost down rapidly. | ▲ Accelerating |
| Geothermal (EGS) | First commercial EGS plants (US, Germany) coming online 2025–2026. $2.2B investment (+80% YoY). Fervo drilling at 30m/hour. | $2.2B invested 2025 | DOE projects <$70/MWh by 2030. 90 GW potential by 2050 in US alone. Data-centre PPAs accelerating. | ▲ Emerging fast |
| Nuclear Fusion | $10.6B private investment 2021–2025. 53 companies. NIF at 8.6 MJ output. DOE national strategy released. Still pre-commercial — zero grid-connected fusion plants exist. | 53 companies racing | First grid-connected fusion plant target: mid-2030s. IEA milestone: net electricity demonstrated by 2030. | ◎ Pre-commercial |
| Battery Storage (Li-ion) | Explosive growth. 15,788 MW added in US alone. IEA projects 1,200 GW globally by 2030. Battery costs fell ~90% since 2015. | 85–95% efficiency | 1,200 GW by 2030 (12x current). Iron-air, solid-state, sodium-ion batteries entering market 2027–2030. | ▲ Dominant |
| Green Hydrogen | Capacity grew 25x from 2021–2024. Cost still $3.8–$11.9/kg vs target $1–2/kg. Round-trip efficiency 35–45% limits grid-scale use. Best suited for industrial sectors. | $1/kg target by 2030 | IEA: electrolyser capacity to exceed 50 GW/year by 2030. Green H₂ for steel, ammonia, aviation becoming primary applications. | ~ Cost challenge |
| Critical Minerals | China tightened export controls 2025. Demand projected to rise 6x by 2030. COP30 first-ever minerals negotiation. US Pentagon invested $1B in domestic rare earths. | 6x demand rise by 2030 | Lithium, cobalt, graphite, rare earths all face supply risk. Recycling and supply diversification urgently needed. Lead times of 20 years make this the transition's greatest structural risk. | ▼ Bottleneck risk |
| India | 50% non-fossil capacity milestone hit 5 years early. 44.5 GW added in 2025 (nearly double 2024). $101B clean energy investment record. | 254 GW RE capacity | 500 GW non-fossil target by 2030. 5 Mt/year green hydrogen. 144 GW/year solar module manufacturing. | ▲ Breakout leader |

Off-grid solar and mini-grids key pathway for 666M without electricity. | ~ Accelerating slowly |
| Latin America | Already 70% renewable electricity. Clean investment fell $81B → $67B in 2025. Needs $150B/year by 2030. Brazil, Uruguay, Costa Rica world leaders. | 70% RE electricity | Offshore wind auctions (Brazil) expected 2026. Critical minerals position (lithium, copper) strategically crucial for global supply. | ~ Potential lagging |
| Global Investment | $3.3T total energy investment in 2025 (record). $2.2T clean energy. But $5.6T/year needed through 2030 to meet Paris goals. | $2.2T clean in 2025 | Need 2.5x current annual clean investment. Emerging markets and developing economies must capture much larger share. | ~ Insufficient pace |
