Do your friends and neighbors tell you that they get “green” power for their home, leaving you wondering: “How can the juice coming from their outlets really be different from my electricity?” Read on to find whether that’s the case and how green power really works!
Renewables are making headway in Europe and bringing a low-carbon electricity system to the forefront. Renewables were 69 percent of new capacity added in 2012 in Europe and 49 percent in the United States. Not surprisingly, this threatens utilities unwilling to let go of outmoded business models and fossil-fuel generation. Should old, long- and often still-subsidized oligopolies be bailed out or shielded from competition when they bet against innovation and lose?
Ever thought of building your own energy efficient cabin ... for $11,000? Prior to moving to Colorado this past summer to work at RMI, one staffer did just that and shares his thoughts on passive solar design, thermally massive materials, solar panels and wood cook stoves.
Did you know? Solar-plus-storage has actually been around for decades. In fact, it was what kickstarted the solar industry in the early 1980s. A bunch of marijuana “farmers” in northern California who weren’t connected to the grid needed a way to get electric lights for their grow operations. A young hippie stumbled upon an ARCO solar panel at a consumer electronics show, and soon after founded AEE Solar and started powering off-grid homes with solar panels and car batteries, and his customers always paid in cash.
At the end of November, SolarCity issued the first publicly known solar asset-backed securitization (ABS), selling $54 million of bundled cash payments. It was a major milestone that many in the distributed solar industry have eagerly awaited. SolarCity’s ABS was a big deal, but there’s more to do
Over the last five years, American inventors and investors have delivered significant progress in developing and deploying key clean energy technologies, supported by Administration policies. Electricity production from solar and wind has doubled. Our cars and trucks go further on a gallon of gasoline, saving families money at the pump. And in 2012, U.S. carbon pollution fell to its lowest level in nearly 20 years. The simple fact is that key clean energy technology costs are continuing to come down, and these technologies are producing more American energy than ever before.
Millions of dollars and massive amounts of fossil fuels are spent cooling homes and buildings covered by conventional roofs that absorb sunlight, get as hot as 185 degrees and radiate that heat inside. Add to that the fact that sunlight-absorbing roofs contribute to the urban heat island effect, which increases air pollution, and it’s easy to see the need for something new. Luckily, there is promise for reducing this burden to the environment and economy — in cool roofs.
TerraLogos Energy Group helps consumers and businesses find saving and improve their energy footprint through their comprehensive energy audits and energy improvement contracting. We asked TerraLogo's co-founder Peter Van Buren to guest blog about their company and the services they offer.
With funding from the Energy Department, the National Renewable Energy Laboratory is working to develop a new insulating window film that preserves the view while increasing occupants’ comfort and saving energy.
