Inhabitat's Week in Green: inflatable concert hall, Xkuty One electric bike and an E. coli filter
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Most of the world still runs on fossil fuels, but renewable energy is making big gains. Not only are renewables better for the environment, but they're also becoming just as cost-effective as their dirtier counterparts. A new study finds that wind farms are less expensive than new coal-fired plants, and they cost about the same as new natural gas plants. Speaking of energy costs, Inhabitat shared a new infographic this week that shows how much it would cost for the entire world to switch over to renewable energy. In other energy news, the world's largest solar thermal energy plant opened in California's Mojave Desert. Once it's operational, the plant will produce enough energy to power 140,000 homes. The largest photovoltaic plant in the world is set to be built in India, and it will produce 10 times as much energy as the next-largest solar plant in the country. And in another exciting development, a team of German and French scientists produced the world's most efficient solar cell, which boats an efficiency of 44.7 percent.
