Rooftop wind system delivers 150% the energy of solar per dollar

Aeromine says its unique “motionless” rooftop wind generators deliver up to 50% more energy than a solar array of the same price, while taking up just 10% of the roof space and operating more or less silently. In independent tests, they seem legit.Cont… Continue reading Rooftop wind system delivers 150% the energy of solar per dollar

Cheap wind harvester generates electricity from a gentle breeze

While wind energy systems can come in some pretty big forms, scientists at Nanyang Technological University (NTU), Singapore have been working on a low-cost solution at the other end of the spectrum. The team has developed an inexpensive device sensiti… Continue reading Cheap wind harvester generates electricity from a gentle breeze

Record energy haul: Offshore prototype operates over capacity for 24 hrs

A prototype wind turbine has recorded an extraordinary single-day renewable energy production total, bringing in a massive 359 megawatt-hours in a 24-hour time period. To get there, it had to operate over its rated capacity, essentially all day long.Co… Continue reading Record energy haul: Offshore prototype operates over capacity for 24 hrs

Giant supertanker uses 9.8% less fuel thanks to 130-foot sails

As the shipping industry moves to decarbonize, huge sails could be making a comeback. The China Merchant Energy Shipping company (CMES) has taken delivery of a new supertanker, whose four large sails will cut down average fuel consumption by nearly 10%… Continue reading Giant supertanker uses 9.8% less fuel thanks to 130-foot sails

1-MW floating vertical axis wind turbine to be deployed off Norway

We’ve been banging on a bit about floating offshore wind turbines lately, but with good reason. Take a look at the US Energy Information Administration’s projected Levelized Cost of Energy (LCoE) figures for 2027, on page 9 of this report. Deep offshor… Continue reading 1-MW floating vertical axis wind turbine to be deployed off Norway

A deeper dive into World Wide Wind’s colossal, contra-rotating turbines

We interviewed the core team at Norway’s World Wide Wind (WWW) to learn more about its floating, tilting, contra-rotating, double turbine design, which it says can unlock unprecedented scale, power and density to radically lower the cost of offshore wi… Continue reading A deeper dive into World Wide Wind’s colossal, contra-rotating turbines

Contra-rotating floating turbines promise unprecedented scale and power

Norway’s World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines (VAWTs) feature two sets of blades, tuned to contra-rotate – and they promise more than double the output of today’s biggest tur… Continue reading Contra-rotating floating turbines promise unprecedented scale and power

GE’s produces world’s largest recyclable wind turbine blade

Through its massive wind turbines and innovative offshore designs, GE continues sharpening its toolkit in a bid to built the future of sustainable energy, and a newly unveiled turbine blade shows how that can extend to the materials used. A consortium … Continue reading GE’s produces world’s largest recyclable wind turbine blade

China plans a mammoth 450 GW of wind and solar in its deserts

China already dominates renewable energy production. Its installed capacity of around 895 GW in 2020 was more than the European Union, the USA and Australia combined. And while the world in general is accelerating its transition to renewable power, Chi… Continue reading China plans a mammoth 450 GW of wind and solar in its deserts
