SEIA recently released its fifth annual Solar Means Business report, which tracks solar adoptions by some of the largest corporations in the US. This year’s top 10 commercial solar-goers list saw Target nab the top spot from long-standing leader Walmart.
Competition aside, the Solar Means Business report 2016 offered a lot of insight into the state of commercial solar, how we interact with corporate solar in our daily lives, and where the industry can improve. Read the rest of this entry »
In a recently released report, the Sierra Club highlights 10 cities across the US that have made commitments to be fully powered by clean energy sources. (Note: their definition of clean energy does not include carbon-based energy or nuclear energy.) Out of the 10 cities described, 4 have already met their 100% clean energy goal.
So how’d they do it?
No two paths to 100% renewable energy are the same, but there are some common factors that have helped these cities make and meet their goals. Here’s our take on the Sierra Club’s 10 case studies. Read the rest of this entry »
It’s been a good year for solar. Jobs are on the rise. Over one million solar systems have been installed across the country. Innovations continue to wow the world (floatovoltaics, solar flowers, and a solar plane to name a few).
As we push forward toward a clean energy future, we must constantly assess and improve upon our processes, our technology, and our methods of communicating the value of solar and sustainability to the public. While not all-inclusive, the recent publication of Solar Power World’s Top 500 Solar Contractors report offers a glimpse into the current state of the industry and the direction we are heading. There’s much to be gained from assessing the key players and sectors of the industry that have pulled ahead—and those that are falling behind. Read the rest of this entry »
Just a few years ago, solar thermophotovoltaics (STPV) was more of a theory than an actuality. The idea behind STPV is that the efficiency of solar modules will improve significantly if certain materials are used to trap the sun’s heat before it reaches the module. Photovoltaics, however, have always had certain limitations, as they can convert only a portion of sunlight into electricity. Since 1961, this limit—known as the Shockley-Quiesser limit, was thought to cap a solar cell’s efficiency around 32 percent. Read the rest of this entry »
