UN Secretary-General Antonio Guterres declared that renewables have reached a "turning point": over 90% of new projects are now cheaper than fossil fuels - solar ~41% cheaper, wind ~53% cheaper. In 2024, investment in clean energy hit $2 trillion, $800 billion more than fossil fuel investment. Guterres warned that fossil fuels "are running out of road," urging global leaders and tech firms to shift rapidly to clean power.
Fact Check: Against WSJ's claim, renewables did not drive the rise in Texas electricity bills. Expert analysis shows that inflation, natural gas price surges, grid upgrade costs, and post‑freeze recovery efforts are the true drivers of higher rates. Meanwhile, clean energy continues to offer long‑term affordability. Experts warn that scaling back solar and wind could raise, not reduce, future energy costs.
MAN Truck & Bus has launched the Smart Charging Cube - a modular battery energy storage system ranging from 500 to 1,100 kWh, with up to four fast-charge ports per unit (400 kW), extendable to 1 MW via external charging, ideal for electric truck depots, construction sites, or grid-limited areas. It supports solar input, peak shaving, bidirectional power flow, and enables rapid deployment without major infrastructure
American consumers - especially EV buyers - are the real payers in Trump's U.S.-Japan tariff deal, warns economist Steve Rattner. Tariffs on Japanese autos don't hurt Japan; they're passed through higher prices at U.S. dealerships. Even American-made EVs using Japanese parts may see cost increases. Though the deal includes Japanese investments, there's no guarantee of job gains. Increased EV prices could slow clean-tech adoption, underscoring the hidden costs of trade policy.
Electric vehicles reduce not only exhaust emissions but also brake dust - a major urban pollutant. A recent EIT Urban Mobility study in London, Milan, and Barcelona found EVs cut brake-dust pollution by 83% due to regenerative braking, significantly improving air quality. While heavier EVs slightly increase tire wear, non-exhaust emissions (brake, tire, road dust) still drop by ~38% overall. Better health, cleaner cities - a win for electrification.
Hydrogen's Flight Path: Fuel Cells, Turbines, and the Economics of Clean Aviation
10 Oct 2025 | Aviation is shifting from Jet A to four fuel systems: electricity, hydrogen (fuel cell and combustion), SAF, and petroleum. Fuel cells suit short-haul aircraft; hydrogen combustion may power long-range jets. SAF bridges legacy fleets. Hydrogen costs - $5-$7/kg today, possibly $2/kg by 2040 - impact ticket prices and infrastructure decisions. Airport authorities, airlines, and governments will share deployment costs. Each fuel has distinct environmental pros and cons shaping aviation's net-zero future.
