QuantaSol breaks efficiency record

‘ At the Royal Society Summer Science Exhibition QuantaSol announced their world record breaking solar cell that is 28.3% efficient. Founded as a spin off from Imperial College in London, the company started in 2007 to focus in commercializing the solar technology developed at the university. QuantaSol not only claims they have developed the most efficient solar cell on the market but they say the manufacturing process is an ease. The company’s secrete sauce to their highly efficient solar cells is the nanotechnology behind their products. This is good news for mass market customers because the trend of the solar industry is more highly efficient at lower costs, this is the perfect recipe for solar power to go mainstream, wouldn’t you...

obama understands lighting efficiency

(AP Photo/Pablo Martinez Monsivais) “I know light bulbs may not seem sexy, but this simple action holds enormous promise because 7 percent of all the energy consumed in America is used to light our homes and businesses” – President Obama Standing next to Steven Chu, Energy Secretary Obama stressed the importance of energy efficiency today. New energy efficiency standards the President announced will result in 4 billion dollars in savings annually between 2012 and 2042. To make this happen Obama has accelerated the disbursements of the 346 million dollars in economic stimulus money set aside for energy efficiency for commercial buildings. This is great news for LED light bulbs since the technology will greatly benefit from the White House’s support. I think with new lighting standards, LED light bulbs will become more affordable through economies of scale. It’s always more cost effective to produce and then produce clean energy, this is a great investment in our future since we are a society of energy wasters, wouldn’t you...

LEDs vs. Incandescents, round one.

We were at the ecotuesday event in Santa Monica this week and people mentioned their curiosity about LED lighting. One member at the event even said he replaced a bulb in his home with an LED light bulb and said he loves it but also mentioned it “costs too much.” Is that really true? Do LED bulbs really cost more than Incandescents, well let’s find out. Below is a table we put together that shows a head to head comparison between a LED and Incandescent bulbs. LED Incandescent Lifespan 50,000 hours 1,200 Hours watts used 7 60 kWh consumed per year 20 175 costs per kWh $0.10 $0.10 total annual operating costs $2.00 $17.50 cost for bulb $49.99 $1.50 replacement costs over 10 years $0.00 $36.50 total investment over 10 years $69.99 $213.00 Comparing the LED with an Incandescent bulb over a 10 year period, it’s quite easy to see that LED bulbs are the more cost effecitve method to go with. Would you agree with our calculations? Do you think LED bulbs a good investment for the...

Seattle buys into LED street lighting

Seattle announced that they would be switching to LED streetlights by investing 6 million dollar of federal stimulus money into replacing 40,000 HPS (high pressure sodium) streetlights to high effiencey LEDs. It’s estimated that the transition to LED streetlights will take between 4 to 6 years. The mayor of Seattle, understands that LED streetlights don’t get as hot as HPS light bulbs. Heat is a key indicator of energy loss. LED streetlights not only save the city on energy costs but also last up to 10 years longer than standard HPS streetlights which reduces annual maintenance costs. If more cities across the US invest in LED streetlights not only would it generate millions of negawatts (negative watts) but it would make LED lights more affordable since the manufacturing volume would increase. What do you think about LED Streetlights? Is your city considering replacing old HPS lamps to LED...

Sharp’s seven shade LED light bulb

Can’t decide between a Cool White or Warm White LED light Bulb? Sharp’s unique LED light bulbs can be adjusted 7 shades so you can have the type of light that fits your mood without having to change the bulb. A remote control that lets you cycle through the different shades of light is included with the Sharp LED Light bulbs A series of Sharp’s LED Light bulbs can be connected to a single circuit and can be all adjusted with a single remote control. The great aspect about LED are they have an efficient lumen to watt ratio and feature an extremely long lifetime. The energy savings combined with savings gained from fewer replacement costs make the return on investment on LED bulbs very attractive for places with high electric rates. Sharp’s adjustable LED light bulb will be released in Japan next month, it’s unknown today when the unique LED bulb will be released to other markets. What do you think about LED light bulbs that allow you to adjust to temperature of the...

the most efficient solar power system ever

There are two types of solar energy systems, solar photovoltaic which turns sunlight into electricity and solar thermal which harnesses the warmth of the sun to provide heating. If you want both typically you’d have to install two separate systems. Although PVTSolar, an innovative company offers a solar energy system that not only produces electricity but can provide heating all in one system! They took a smart approach in turning a problem into an efficiency by controlling the heat that typically reduces performance on solar photovoltaic panels into an asset for water and space heating. By taking the heat that typically harms photovoltaic production and putting it to good use, PVTSolar claims they have the most efficient solar energy system in the world. According to the company, the PVTSolar power system will not only look good but it will cost 25% more than a regular photovoltaic system but since it can provide both your electric and heating needs the system will save you more money in the long run. What do you think of PVTSolar revolutionary echo solar energy system that can knock out more of your energy...
