Stanford researchers develop a way to store solar energy more cost-effectively for use at night

solar energy storage

How electrolysis could produce hydrogen as a way to store renewable energy.

There isn’t a cost-effective way to store large-scale solar energy. But researchers at Stanford have developed a solution by using electrolysis to turn tanks of water and hydrogen into batteries. During the day, electricity from solar cells could be used to break apart water into hydrogen and oxygen. Recombining these gases would generate electricity for use at night.

New hybrid solar cell battery could solve solar power’s energy storage problem

solar-panel-houses1

Researchers at Ohio State University have created a new hybrid device that can act both as a solar cell and as a battery storing that energy.

Scientists, entrepreneurs and government leaders are pushing to develop cheap, clean energy as the world seeks out alternatives to fossil fuels.

Minnesota to launch solar highways.

Solar arrays could soon be seen along the public rights-of-way that line the state’s highway in Minnesota. The Minnesota Department of Transportation has released a request for proposal (RFP) accepting bids to build and manage solar arrays, which would provide the state’s grid a new and reliable source of clean energy for at least 20 years.

How power companies will commit suicide by solar

solar power

Installing solar panels.

Anyone with enough roof space will be leaving the grid within the decade for solar power. And in most cases they won’t be leaving just one grid, they will be leaving two. That’s because solar is going to become, to put a new spin on an old phrase, “too cheap to have a meter”. It just won’t be worth paying daily service charges to have a grid supplied meter and grid access.

Naval Facilities Energy Initiatives manager goes ‘net zero’ on his home in D.C.

Knox-Backyard-Finsihed-Solar-Geo

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.

Solar and wind prices plunge below fossil fuel prices

solar and wind

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

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 20 kilowatts of heat on a sunny day—enough to power several average homes. It can also produce clean, fresh water as a result of the process used to cool the solar cells. (Video)

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

SolarCity

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.

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

clean energy

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 market size would be about 900,000 units and advised AT&T to pull out.

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

SolarHomePrices

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 houses show clearly that homes—even near-identical homes in the same community—sell for more with solar. But we know you don’t want to read a 200-page PDF to find out, so we’ve collected some of the most important information below.
