Researchers design roadmap for hydrogen supply network

[ad_1] Walter Mérida Credit: UBC Transportation is the largest source of greenhouse gas emissions in British Columbia. Researchers at the University of British Columbia have developed a hydrogen supply chain model that can enable the adoption of zero-emission, hydrogen-powered cars—transforming them from a novelty into everyday transportation in just 30 years. In a new study […]

Device generates light from the cold night sky

Photovoltaics could cool our homes with the power of the sun

[ad_1] Credit: CC0 Public Domain The International Energy Agency has dubbed increased global cooling demand as one of the most critical blind spots in today’s energy debate. A new study titled “Meeting Increased Global Cooling Demand with Photovoltaics during the 21st Century” yields critical new insight to a fundamental question: What is the required photovoltaic […]

It's not about self-driving cars, it's about more people in fewer vehicles

[ad_1] Credit: CC0 Public Domain This year alone, there are about 276 million vehicles operating on roads throughout the United States. Despite the current fascination with the concept of self-driving cars and their potential to reduce traffic congestion, a researcher at Florida Atlantic University says that may not be a solution. It now appears that […]

Interest rates are a decisive factor for competitive renewables

[ad_1] As renewable energy is more capital-intensive than fossil fuels, the costs rise more sharply with rising interest rates, making it less attractive. Credit: Shutterstock Renewable energy has become competitive—and one often-overlooked reason is the reduced cost of financing. Researchers from ETH Zurich and the Potsdam Institute for Climate Impact Research (PIK) have modeled different […]

Volkswagen bets big on electric. Will consumers buy in?

Volkswagen is rolling out what it bills as the breakthrough electric car for the masses, […]

China data centres set to consume more power than Australia: report

[ad_1] While China leads the world in renewable energy capacity, data centres in the country remain dependent on coal China’s data centres –- the backbone of the country’s fast-growing digital economy—are on track to guzzle more electricity by 2023 than all of Australia last year, said a Greenpeace report published Monday. While China leads the […]

E-bike grumbles echo in the Bavarian Alps

[ad_1] Ursula and Robert Werner are convinced of the virtues of e-bikes, but not everyone agrees Robert Werner and his wife Ursula usually make time to say a friendly hello to hikers as they ride their gently whirring e-bikes up trails in the Bavarian Alps. But more often than not, their greetings are met with […]

A globalized solar-powered future is economically unrealistic

[ad_1] Credit: Valentin Valkov/Shutterstock.com Over the past two centuries, millions of dedicated people—revolutionaries, activists, politicians, and theorists—have been unable to curb the disastrous and increasingly globalized trajectory of economic polarization and ecological degradation. This is perhaps because we are utterly trapped in flawed ways of thinking about technology and economy—as the current discourse on climate […]
