The Knox home has geothermal loops buried under the backyard. Andrew Know, manager of Naval Facilities Energy Initiatives, decided to go “net zero” on his home in Washington, D.C. What Knox got was a true zero-energy home, done right on a budget.    



Tesla to focus on the grid-scale energy storage business

October 17th, 2014 at 9:52 am » Comments Off

Mateo Jaramillo, Tesla’s Director of Powertrain Business Development, was the keynote speaker at last week’s Energy Storage North America. He spoke of Tesla’s aggressive efforts in stationary storage.    



Graphene supercapacitors could provide energy for flexible electronics

October 16th, 2014 at 9:58 am » Comments Off

A research team has created an energy storage device that is highly flexible and stretchy. How long would your battery last if your phone was always awake and processing data? Would the battery last three hours? One hour? The next generation of electronics will require that kind of always-on energy consumption, but our current batteries are […]



Maine to harness wave power to generate electricity

October 14th, 2014 at 2:32 pm » Comments Off

Maine is geared to join hands with other few states to generate electricity from tidal waves. With increasing global warming and increasing awareness of other environmental hazards, more and more people across the world are focusing on harnessing natural sources of energy like wind energy. Wave power is a renewable source of energy and is […]



Solar and wind prices plunge below fossil fuel prices

October 13th, 2014 at 1:07 pm » Comments Off

Renewable energy shows an average price decline over the last 5 years of 78% for utility scale solar and 58% for wind. Lazard, an asset management firm, has a fascinating new analysis of renewable and other energy prices out. There are a huge number of insights in this, from an outside analyst whose primary interest is financial. […]



Airlight Energy and IBM’s new sunflower-shaped solar concentrators produce energy and fresh water

October 1st, 2014 at 9:55 am » Comments Off

High Concentration PhotoVoltaic Thermal (HCPVT) A cutting-edge solar system that resembles a 10-meter-high sunflower has just been unveiled by IBM Research and Swiss solar technology company Airlight Energy. The High Concentration PhotoVoltaic Thermal (HCPVT) system can concentrate the sun’s radiation 2,000 times and convert 80 percent of it into useful energy, generating up to 12 kilowatts of electrical power and […]



Elon Musk’s SolarCity to build a Gigafactory for producing solar panels

October 1st, 2014 at 9:36 am » Comments Off

Tesla/SpaceX chief and sustainable energy champion, Elon Musk, has finalized plans to build a 1.2 million square-foot megafactory in Buffalo, NY through his company SolarCity. The factory targets to create enough solar panels a year to harness a gigawatt of the sun’s energy.    



New fuel cell system will heat and power homes using natural gas

September 30th, 2014 at 10:47 am » Comments Off

The fuel cell system is based on the solid oxide fuel cell (SOFC) technology. Those interested in off-the-grid heating and power sources for the home might soon be getting a new option. The Germany-based Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) has joined forces with the heater manufacturer Vaillant and together they have come […]



We are headed into an era of unlimited and free clean energy

September 29th, 2014 at 12:21 pm » Comments Off

Inexpensive renewable sources will provide more energy than the world needs in less than 20 years. Leading consultants were skeptical about cellular phones in the 1980′s. McKinsey & Co. noted that the handsets were heavy, batteries didn’t last long, coverage was patchy, and the cost per minute was exorbitant. It predicted that in 20 years the total […]



Are homes with solar worth more than non-solar homes?

September 23rd, 2014 at 11:20 am » Comments Off

We have been talking about how much solar panels increase the value of your home for years. We use a simple calculation to determine the increase in value: We add the energy savings you’ll see per year for 20 years. Well, it looks like we’re not just blowing solar smoke; study after  study after study comparing sales of solar and non-solar […]
