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

IBM-solar-concentrator

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)

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.

$100B invested in wind or solar will produce more energy than oil

Solar-panel-array-and-wind-turbines-

By the late 2020s or early 2030s renewables could be competing much more aggressively with the oil market.

Kepler Chevreux, a French investment bank, has produced a fascinating analysis that has dramatic implications for the global oil industry. The investment bank estimates that $100 billion invested in either wind energy or solar energy – and deployed as energy for light and commercial vehicles – will produce significantly more energy than that same $100 billion invested in oil.

Japan to build the world’s largest floating solar power plants

Solar-Power-Plant

One of Kyocera’s existing solar power plants in Japan, which has 70 MW of power capacity.

Being short on free land space is not stopping Japan from investing in renewable energy. Solar panel company Kyocera Corp, Century Tokyo Leasing Corp and Ciel Terre have announced that they’re teaming up to create two huge floating solar power plants which will be up and running by April next year.

The next big challenge for energy storage

solar energy

Solar is now the fastest growing segment in the energy business in the U.S.

The energy storage era is upon us. States like California and New York have adapted energy policies that will make it possible to economically deploy storage systems, while technology advancements have boosted performance and trimmed costs. For the first time in history it will become feasible to store electric energy.
