US Foods recently announced it will save an additional 2 million kilowatt hours (kWh) by retrofitting lighting throughout the organization. Since 2007, the company has decreased overall energy use by approximately 8% (34 million kWh) through lighting retrofits alone. “We’re exploring many more opportunities for energy savings throughout the company,” … [continued]
A recent Wall Street Journal article showed that lower maintenance costs are driving companies like Walmart, GNC, and Caesars Entertainment to retrofit their specialized lighting fixtures to LEDs. Due to the long life span of LED’s, the maintenance cost for the fixture is dramatically decreased, putting the total cost savings … [continued]
With congested cities that continue to grow, more and more cities are looking towards public transportation as a way to move people around and get people not using cars. However, despite the benefits of public transportation, many public transit buses still run on good old fossil fuel diesel. With … [continued]
Together with nonprofit Empowered by Light, SF’s Lemnis Lighting is bringing clean, renewable energy efficient solar LED lighting to rural villagers in Zambia who lack access to electricity. Lemnis is running an innovative “buy one, give one” promotion throughout December in which it matches every Pharox Solar Kit purchase with a donation to Empowered by Light’s Solar: Zambia program.
SCHOTT Solar is producing silicon solar PV cells with nearly 20% efficiency at comparatively low cost using a combination of innovative technologies that promise to drive the cost of manufacturing solar photovoltaic cells, and the cost of producing electricity from solar energy, further down the curve.
According to a University of Texas (in Austin) press release, solar cells could extract twice as many electrons from each photon of sunlight received. This would be achieved using an organic plastic semiconductor material.
This is a repost from the indomitable Climate Pirate. It’s longish (but peppy…absorbing…nay bewitching), so we begin with a synopsis: There are a schmillion people addressing climate change in a schmillion ways, most of which won’t work without Carbon Pricing thanks to a horror I call Whac-a-Gas (if you don’t … [continued]
This is, clearly, not a definitive analysis showing that renewable energy such as wind and solar lower electricity rates (or make them increase more slowly), but it is a pretty darn good argument in their favor! And it is also a great piece to share with anyone who thinks renewable … [continued]
Renewable energy critics are convinced that Germany is going to see skyrocketing electricity prices due to it dropping both coal and nuclear. Well, anyone who looks at the long-term economics of all these options knows that clean, renewable energy is a winner (don’t be a hater, it’s just how it … [continued]
Scientists at National Renewable Energy Laboratory (NREL) reported “the first solar cell that produces a photocurrent that has an external quantum efficiency greater than 100 percent when photoexcited with photons from the high energy region of the solar spectrum” at the end of last week. Promising news. More from NREL: The … [continued]
