Vegan leathers are complicated by questions of commercial viability and sustainability. How do they compare to traditional leather? Change by degrees offers life hacks and sustainable living tips each Saturday to help reduce your household’s carbon footprintGot a question or tip for reducing household emissions? Email us at changebydegrees@theguardian.comIn sustainable fashion, breathless promises about vegan leather have arrived thick and fast for over a decade. Innovations promise mushroom and cactus alternatives that look and feel like real leather – minus the negative associations with methane, deforestation, chemical pollution and animal welfare.While these next-gen materials have absorbed billions of dollars in capital under an environmental banner, experts are concerned they remain a shiny distraction while the fashion industry’s emissions and reliance on fossil fuel-derived materials grows.

#clean energy #electricity #energy #fuel #fuel cell #fuel cells #hydrogen fuel #hydrogen fuel cell #study

Chinese scientists have developed a way to generate a fourfold increase in power output of hydrogen fuel cells, an advance that could broaden their use from road vehicles to space missions. Hydrogen is widely viewed as a promising clean energy source for a low-carbon future. Fuel cells convert the chemical energy in hydrogen directly into electricity, producing water as their only exhaust. In a study published in the peer-reviewed journal Science on Thursday, researchers at the Beijing Institute...
