  • New York City could open up 1,200 acres of rooftops for farming

    Given how valuable space is in New York City, the city's rooftops are strangely empty. But a proposal from the city's planning department could change that by making 1,200 acres of commercial rooftops available for urban farmers to open greenhouses across the city.

  • Tile your roof with solar shingles

    If you want to generate some solar energy but don't want to have weird-looking solar panels on your roof, Dow Solar has a solution for you. The company has achieved solar shingularity: Its roof shingles are solar panels! The solar panels are shingles! The discerning homeowner can live out green dreams while still conforming to […]

  • Heat from cities barely affects global warming

    One of the many arguments that deniers rely on to pooh-pooh climate change is the prevalence of the “urban heat island” effect, i.e. the tendency for cities to absorb and retain heat. The problem’s not gas-belching cars and factories, it’s all those city-dwelling lefties! But according to a new study from Stanford University, there's just no possible way that cities are causing global warming, at least not on the same scale that greenhouse-gas emissions are.

    At most 4 percent of "gross global warming since the Industrial Revolution" can be traced back to urban heat island, the study found. Greenhouse gases are responsible for 79 percent. So, if you live in a city, don't sweat it! If you've commuted for 1.5 hours in a car for the past two decades, maybe sweat it.

    The study also contained some bad news about white roofs.

  • Soiled diapers can now end up as roof tiles

    Babies! They use so much energy that the best thing you could do to save the human race from climate change might be to avoid having one altogether. But if you choose the reproductive path, at least the 6,000 poopy diapers that your offspring will produce in the course of his or her early years could have a second life as part of your house -- specifically, as the shingles tiling your roof.

  • Local solar could power the Mountain West right now, all of America in 2026

    If the U.S. had kept pace with German solar installation, we'd be on our way to being a 100 percent solar-powered nation.
