  • Toshiba to Get Energy From the Ocean

    The well known Japanese company Toshiba and its perhaps not as well known co-patriate IHI have been tapped to pilot a new ocean energy project that will deploy a phalanx of underwater turbines that float like kites. The project demonstrates once again how legacy companies are transitioning to new clean tech. At a little less […] More

  • Efficient Wind Power Designs Advance Clean Tech Cause

    So far, the story of the US renewable energy transformation has skipped a key chapter, which is the exploitation of our massive offshore wind power potential. In the offshore wind category, the US has been lagging far behind other nations. However, the spotlight is starting to swing out to embrace this wind power option, and […] More

  • Generation Gap: Wind Power Opens Big Lead over Nuclear in China

    By J. Matthew Roney In China, wind power is leaving nuclear behind. Electricity output from China’s wind farms exceeded that from its nuclear plants for the first time in 2012, by a narrow margin. Then in 2013, wind pulled away—outdoing nuclear by 22 percent. The 135 terawatt-hours of Chinese wind-generated electricity in 2013 would be […] More

  • New Data Center Technology Could Reduce Energy Demands

    The world is creating massive amounts of data at alarming rates. In fact, the amount of data that exists doubles every two years. If that doesn’t seem like a big deal, consider the fact that every piece of data currently must reside somewhere on a physical server, either within a data center or on a […] More

  • The Pedal Powered Generator Goes Open Source

    Building a simple pedal-powered generator isn’t that difficult – we got one (kind of like the one above) going on the fly nearly four years ago at the last blogathon up at Dancing Rabbit.  It didn’t really generate enough power reliably to help us, though – that takes a bit more engineering. If you want […] More

  • Ever Want to Hire Someone to Implement All Those Sustainable Lifestyle Tips?

    Need some pointers on how to cut electricity, water, and/or gas use? Identify the toxins in your home? Label food products that contain GMOs? You don’t have to look far: green living tips have become standard content throughout the sustainable blogosphere (including here at sustainablog). Of course, you actually have to implement these tips to […] More

  • Save Money on Your Heating with these Easy Home Projects

    No time left to think about cold-weather energy efficiency projects: it’s time to get them done if you want to cut your heating costs. As in most years, doing nothing will cost you more: the U.S. Energy Information Administration is predicting residential electricity prices in the U.S. to rise 2.2% compared to the Winter of 2012-13.

  • 2013: Record Year for Offshore Wind

    Offshore wind power installations are on track to hit a seventh consecutive annual record in 2013. Developers added 1,080 megawatts of generating capacity in the first half of the year, expanding the world total by 20 percent in just six months. Fifteen countries host some 6,500 megawatts of offshore wind capacity. Before the year is out, the world total should exceed 7,100 megawatts. Although still small compared with the roughly 300,000 megawatts of land-based wind power, offshore capacity is growing at close to 40 percent a year. More

  • Anaerobic Digestion: a Clean Energy Solution for Your Business [Infographic]

    Anaerobic digestion – extracting methane from organic wastes – doesn’t get the love of, say, solar and wind: it’s not nearly as sexy, and definitely more smelly. But it’s also a renewable energy technology with plenty of available feedstock: all of that food waste we discuss regularly could go towards the creation of biogas. More

  • U.S. Carbon Dioxide Emissions Down 11 Percent Since 2007

    Carbon dioxide emissions from burning fossil fuels in the United States peaked at more than 1.6 billion tons of carbon in 2007. Since then they have fallen 11 percent, dropping to over 1.4 billion tons in 2013, according to estimates from the U.S. Energy Information Administration. Emissions shrank rapidly during the recession, then bounced back slightly as the economy recovered. But shifting market conditions, pollution regulations, and changing behaviors are also behind the decline. More

  • U.S. Nuclear Power in Decline

    Nuclear power generation in the United States is falling. After increasing rapidly since the 1970s, electricity generation at U.S. nuclear plants began to grow more slowly in the early 2000s. It then plateaued between 2007 and 2010—before falling more than 4 percent over the last two years. Projections for 2013 show a further 1 percent drop. With reactors retiring early and proposed projects being abandoned, U.S. nuclear power’s days are numbered. More

  • Charge Your Cell Phone with Fire! (w/ video)

    Introducing the FlameStower, a portable charger for small electronics that converts heat energy to electrical energy to keep your high-tech gadgets alive off the grid. Way off, if it comes to that. Why would you ever need to charge up your cell phone or iPad that far off the grid? I’m glad you asked! Consider […] More

  • World Solar Power Topped 100,000 Megawatts in 2012

    The world installed 31,100 megawatts of solar photovoltaics (PV) in 2012—an all-time annual high that pushed global PV capacity above 100,000 megawatts. There is now enough PV operating to meet the household electricity needs of nearly 70 million people at the European level of use. More

  • Five Ways to Keep Cool this Summer (and Keep the Energy Bill in Check)

    Despite news of melting ice caps and dying polar bears, the first instinct for most people in the hot summer months is to crank up the air conditioning. While reducing carbon footprints may seem like an impossibly grand task, there are ridiculously easy ways to save on home energy consumption, as well as your monthly bill. Here are five ways to save energy this summer More

  • Thirteen Elements of a Dream Green Home [Infographic]

    Got a dream green home you’d love to build? Sure, you’ll probably want to include solar panels in the building… but that’s just one element. Green building involves making the most efficient use of the materials that go into the building, and creating a space that allows for sustainable use of resources needed to live in that home. More

  • Harvesting Justice 9: Farmers and Consumers vs. Monsanto – David Meets Goliath

    Via Campesina, the world’s largest confederation of farmers with member organizations in 70 countries, has called Monsanto one of the “principal enemies of peasant sustainable agriculture and food sovereignty for all peoples.” See how peasant farmers, and the activists who support them, are challenging the agribusiness giant’s incursions into developing world farming.

  • Food to Fuel… the Right Way [Infographic]

    The phrase “food to fuel” often refers to production of corn-based ethanol or soy-based biodiesel… not exactly most efficient use of these commodities. But there are situations when food to fuel represents a smart use of resources: when that food will go to a landfill. While the capture of landfill gas has become more prevalent, why spend the money and other resources shipping it there? Why not just direct food waste to energy production? More

  • Wind Power Surpasses Nuclear in China

    Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. More
