Hybrid perovskite-silicon solar cells have reached power conversion efficiencies over 34%, far surpassing conventional silicon panels at 24%. The first commercial versions are expected to reach the market in 2026.
The journal Science named the global renewable energy surge its 2025 Breakthrough of the Year. For the first time, renewables surpassed coal as a source of electricity worldwide, with solar and wind growing fast enough to cover the entire increase in global electricity demand in the first half of the year.
Portugal generated 80.7 percent of its electricity from renewable sources in January 2026, ranking second in Europe behind Norway's 96.3 percent. The achievement demonstrates that large-scale renewable energy transition is achievable for Southern European nations and validates Portugal's aggressive clean energy investment strategy.
A staggering 80.7% of Portugal's electricity in January 2026 came from renewable sources, placing the country second in Europe for clean energy generation — a remarkable achievement for the Iberian nation.
Portugal has surged to the top of the EU renewable energy leaderboard, with a staggering 80.7% of its electricity in January 2026 coming from renewable sources — the country's best result in nine months and a powerful demonstration of what the clean energy transition looks like in practice.
Energy companies are repurposing retired wind turbine blades into sustainable tiny homes, addressing both the renewable energy waste problem and the housing crisis.
Renewable energy sources now generate 35% of global electricity, a new record that puts the world on track to meet key climate goals.
Solar energy was confirmed as the fastest growing source of electricity in history in 2025, growing from 1% to 9% of global electricity in just a decade. Combined with wind, renewables overtook coal as the world's leading electricity source for the first time.
A US judge has upheld the right to build offshore wind farms for the fifth time, ensuring the continued growth of renewable energy despite legal challenges.
Europe has reached a significant energy tipping point, with renewable sources now generating more power than ever and accelerating the transition away from fossil fuels.
Science Magazine declared the unstoppable rise of renewable energy as 2025's Breakthrough of the Year, with China installing record-breaking solar and wind capacity.
For the first time, renewable sources generated a third of the world's electricity in 2025, with solar and wind leading an accelerating energy transition.
Australia announced it will provide at least three hours of free solar-generated electricity per day to all households — even those without solar panels — thanks to massive renewable energy capacity.
Northwestern University researchers transformed an industrial waste product into a battery for storing sustainable energy, opening the door for redox flow battery technology.
All 411 buildings owned by the City of Chicago now run on renewable energy or offset emissions, powered largely by the largest solar farm east of the Mississippi.
A Stanford study found that firebricks heated via renewable electricity could replace 90% of fossil fuels burned by heavy industry for heat, named among top innovations of 2024.
