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.
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 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 […]
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. […]
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 […]
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.
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 […]
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 […]
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 […]
