Energy efficiency in the US is much light and little heat – literally. Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste.

“Policy is electricity-centric in the US. Unless you are making kilowatts, the most efficient investments are (more…)

Balancing the big picture with the details can be tricky. However, finding this balance can be very powerful when addressing a building’s energy needs and energy costs.

One way of achieving good balance is to take an integrated approach that looks at the synergistic (more…)

The Niagara Tunnel Project in Ontario, Canada has reached a significant milestone with half of the tunnel now fully lined with concrete.

When it is finished, the smooth concrete lining will ensure the efficient and uninterrupted flow of Niagara River water through this 10.2 km tunnel to the Sir (more…)

This week our friends at Environment California released a new report ranking California cities by the amount of solar they’ve installed. The good news?

“From Fresno to San Francisco and Clovis to Culver City, solar power is becoming a mainstream technology throughout California,” said Michelle (more…)

$1/Watt PV System – BoS /Installation Challenges for Ground Mounted Systems

The $1/watt White Paper from the U.S. Department of Energy was a great start to kickoff discussions and movements towards the goal of making solar power competitive without any incentives. To achieve this goal, the cost of an installed PV system would break down into the following components: (more…)

This house is beyond cool. Those in Southern California should swing by the California Science Center in downtown Los Angeles to tour a solar home nonpareil.

Known as the CHIP house, for “Compact, Hyper-Insulated Prototype Solar House,” the home was designed and built by students of the Southern California Institute of Architecture (SCI-Arc) and the California Institute of Technology (Caltech).

The project won first prize in the Energy Balance division of the Department of Energy’s Solar Decathlon competition held in Washington, D.C..

On approach, the CHIP house looks as if it’s been turned inside-out. CHIP wears the heart of its green technology on its sleeve. Most of the home’s exterior is wrapped in insulation, a flexible, quilted vinyl membrane.

It’s this exterior insulation, combined with solar technology, that creates the high R-values necessary for a net-zero dwelling. The home looks a bit like a giant pillow topped with a solar panel hat.

CHIP is equipped with 45 solar panels, enough to provide three times the amount of energy the house consumes. The intention was not only to power the home, but to keep two electric cars up and running as well. As the primary sponsor for the CHIP project, Hanwha SolarOne, from their North American headquarters in nearby Costa Mesa, provided the panels.

It’s not the solar panels that make this 750-square-foot home so distinctive, but the way that the panels, and the entire home’s green technology, are operated. The CHIP home interface uses Apple iPad apps and an Xbox Kinect system as a master command center.

Residents not only can operate the home’s lights and electronic devices, but monitor the home’s energy systems by using natural gestures like pointing and waving their arms. The home is equipped with 3-D cameras, too, that signal light to turn on and off as residents move through the space.

The interior of the home features a single, open space, with living areas defined by a series of platforms, terraces that climb upwards and inwards into the home. Private areas occupy the highest platforms. The open floor plan is arranged around the natural flow of daily activities.

It took more than 100 students, two years and $1 million in funding to build CHIP, although the project team estimates that replicating the home elsewhere would cost about $262,000. You can take a look at the CHIP home, inside and out, at the California Science Center, through May 31, 2012. Free tours are available every weekday from 10 a.m. to 1:30 p.m. and on weekends from 10 a.m. to 4 p.m.

Ocean Thermal Energy Conversion (OTEC) is an idea for creating renewable energy by exploiting the difference in ocean temperatures between the surface and the seabed. The OTEC permit office first opened in 1981 as part of NOAA, America’s National Oceanic and Atmospheric Administration, the marine counterpart to NASA. It was created after the oil price (more…)

Tick tock, tick tock… The ticking sound that our friends in Germany might be hearing is the countdown to 2022, the year in which the country has pledged to be completely nuclear free.

Meanwhile, halfway across the globe, Japan is still dealing with the aftermath of the meltdown at its Fukushima Daiichi nuclear power facility. The disaster greatly damaged public confidence in the safety of nuclear power, leading many countries to question their own commitment to nuclear power.

As Germany, Japan, and other countries seek to phase out nuclear power, they need to design strategies for filling the “energy gap” created by nuclear power’s absence. Renewable energy sources provide the clearest, cleanest path for filling this gap, and many different forms of renewables currently exist as viable options.

Germany-based TimberTower develops massive, easily assembled wooden towers that can be used as the base for wind turbines, much the way wood was used as the foundation for windmills for many centuries. More flexible, renewable and easier to manufacture and produce than metal turbines, the wooden towers make sense for a forest-rich region.

Clean technology company SunPods Inc.—headquartered in San Jose, Calif.—designs and manufactures modular solar array units that help make solar power more accessible and affordable. Unlike conventional customized ground-mounted solar arrays that require extensive onsite assembly and construction, SunPods (which stands for “Sun Power on Demand”) are configured and built in a factory before being delivered to virtually any site — a process that reduces installation time by up to 85 percent, allowing sunny regions to readily harvest the solar power available to them.

Tidal power presents another option for renewable energy for countries with available coastline. IT Power—based in Bristol, UK—is developing an innovative tidal energy device that uses oscillating horizontal hydrofoils instead of traditional rotating blades to generate renewable energy. This pioneering approach offers many advantages over existing tidal stream technology by maximizing the area that can be swept—and hence the power captured—in a given depth of water.

Wind, solar, tidal power, and other renewables all have a role to play in helping countries seeking to move away from nuclear achieve their energy goals. How these countries fill “the energy gap” will be a bellwether for others working to diversify their energy mix.

There are many solar energy gadgets out there, but some of them seem to stand out. Take the LightShip, for example. It is a practical, portable solar light that could be the clean energy answer to campers, boats, cabins and emergency use. I particularly like the fact that it features three suction cups so that you can attach it to any smooth surface! (more…)

The promise of smarter homes continued to make noise at this year’s CES, the world’s largest consumer electronics show. But nothing really wowed me. You might call this an incremental show – and that’s not necessarily a bad thing.

Keep in mind that CES is huge, with 1.86 million net (more…)
