Cheap solar power and endangered animal comebacks: Positive environmental stories from 2025

Euronews Green’s year-long roundup highlights accelerating structural shifts in the energy and environmental landscape: global solar and wind generation has outpaced coal for the first time, renewables provided a record >40% of world electricity, the EU produced 54% of its power from renewables in Q2 2025 (solar reached 11% of EU supply in 2024 and became the bloc’s main source in June), Poland saw renewables (44.1%) edge out coal (43.7%) in June, and analysts report that more than 90% of new renewable capacity is now cheaper than fossil fuels. Coupled with policy and legal momentum (courts upholding fossil-fuel ad bans, national coal phase-outs), corporate moves toward carbon-neutral operations, and emerging commercial technologies—from waste-derived batteries and agrivoltaics to lab-grown oils and seaweed-based materials—these trends strengthen the investment case for clean power, grid flexibility and storage, electrification infrastructure, and nature-based/tech-enabled solutions while heightening long-term downside risk for carbon-intensive assets.

Analysis

Euronews Green's year-long roundup documents a clear structural shift: global low-carbon electricity topped 40% and the EU generated 54% of its power from renewables in Q2 2025, with solar rising to 11% of EU supply in 2024 and becoming the bloc's main source in June. Solar and wind have outpaced coal this year and more than 90% of new renewable capacity is now cheaper than fossil fuels, while Poland's June mix (renewables 44.1% vs coal 43.7%) illustrates regional displacement of thermal generation.

Policy, corporate and technological developments are reinforcing the transition: legal actions curbing fossil-fuel advertising, Finland's coal plant decommissioning, LEGO's $1bn zero-emissions factory and Vatican solar plans point to regulatory and corporate capex tailwinds. Innovations cited — redox flow batteries from waste, agrivoltaics, lab-grown oils and seaweed packaging — address storage, land-use and supply-chain bottlenecks and broaden investable themes beyond generation.

Risks include permitting and social pushback, grid flexibility and storage shortfalls, and a timing gap between positive narratives and listed-company earnings; sentiment and market-impact signals are moderately positive but not yet a binary catalyst. Investors should watch deployment cadence, policy implementation and commercialization milestones to translate structural trends into durable cash flows.

Key Decisions for Investors

• Increase selective exposure to utility-scale solar and onshore wind developers and to grid-scale battery and long-duration storage providers, focusing on companies with confirmed project pipelines and contracted revenues
• Tilt allocations toward electrification plays — EV component suppliers, charging infrastructure and power electronics — given accelerating EV uptake and near-term grid upgrade needs
• Allocate a modest, disciplined tranche to decarbonization and circular-economy innovators (waste-to-battery, agrivoltaics, seaweed-based materials, lab-grown oils) but limit sizing until commercial-scale margins are visible
• Underweight or hedge European coal and carbon-intensive assets exposed to accelerated phase-outs and adverse court or regulatory outcomes, and monitor country-specific timelines
• Monitor leading indicators — auction results, build permits, storage deployments, curtailment rates and corporate capex guidance — and adjust positions as those metrics confirm revenue visibility
