First US Power-to-Gas Plants Open in California and Colorado

The first power-to-gas plant in the US opened in California

Southern California Gas Company (SoCalGas) is bringing science fiction to life, launching two demonstration projects to create and test a carbon-free, power-to-gas system for the first time ever in the U.S. The technology converts electricity into gaseous energy and could provide North America with a large-scale, cost-effective solution for storing excess energy produced from renewable…

Using Science to Get the Most Out of New Windows

Australia’s Sustainable Window Alliance (SWA) is using science to measure the properties of energy efficient windows for residential applications. The groups says that while windows represent only 8% of a home’s exterior surface, they can account for up to 60% of unwanted heat loss in winter and 91% of unwanted heat gain in summer … and that…

In a Brazilian neighborhood plagued by blackouts, panels under the turf of a neighborhood soccer field, fueled by players running over them, provide electricity to light the field and the surrounding homes.  A typical soccer player can run up to seven miles during a football game.  Most of the players in this neighborhood are local…

Your Solar Panels Are Facing the Wrong Way

Conventional wisdom says that panels should be installed facing south to get the most solar exposure (in the northern hemisphere). South-facing panels create the most power in the morning and mid-day, but peak demand for electricity typically occurs in the late afternoon. Because of that, a number of solar experts have begun to say that…

Fiberglass Windows Are More Energy Efficient

For making energy efficient windows, fiberglass composites offer many advantages over wood, aluminum and vinyl. Wood warps and rots over time, allowing air infiltration that undermines the insulating power of the glass. Aluminum conducts heat and cold into the interior of buildings. And vinyl can weaken with age leading to a breakdown in insulating power. Fiberglass…

Low-Cost Building Skin Cools While Using No Energy

Building skin cools building

Imagine a building that self-regulates its temperature without electronics. A building that adapts, allowing outside air in as needed and eliminating the need for air conditioning, but that uses no energy in doing so.  A University of California-Berkley research team has developed a new type of “building skin” that can do just that, and they…

Amazon Heats Building With Data Center Waste Heat

Old tech- in the form of hydronic heating– meets new in nearby data centers, creating ‘green heating’ in Amazon’s latest new buildings in Seattle, WA. The offices and work areas of the new Amazon buildings will be heated by utilizing the waste heat of a nearby data center, and Amazon’s not stopping there. Heat from the…
