The chemical used to make tofu and bath salts could also replace a highly toxic and expensive substance used to make solar cells, a new study has revealed. Cadmium chloride is currently a key ingredient in solar cell technology used in millions of solar panels around the world. This soluble compound is highly toxic and expensive to produce, requiring elaborate safety measures to protect workers during manufacture and then specialist disposal when panels are no longer needed.

The Rise of Solar Co-ops
Renewable Energy World
While many people associate cooperatives with a place for hippies to buy organic food, the cooperative movement has actually grown far and wide, creating sustainable enterprises that generate jobs and strengthen local economies.Today, there are nearly 30,000 cooperatives in the United States, with more than 100 million members. From day care centers to hardware stores, cooperatives seem to be permeating every sector of society. So it’s no surprise that cooperatives are making their way into the renewable energy field as well.

Rooftop Solar Leases Scaring Buyers When Homeowners Sell
Renewable Energy World
For people who own rooftop power systems, solar adds value to the home -- about $25,000 for the average installation in California, according to a study in December by the Lawrence Berkeley National Laboratory, funded by the U.S. Energy Department’s SunShot Initiative. Leased systems are another story because they’re considered personal property rather than part of a house. For many potential buyers, a solar lease is a liability rather than an asset, and may drive some people away.

Storm Clouds Gathering Over the US Solar Industry
Renewable Energy World
Tony Clifford, CEO of Standard Solar and a keynote speaker during PVAmerica 2014 spoke about three pitfalls that he sees in the coming years for solar. The first words of warning were regarding the solar trade case between the U.S. and China, which he attributes to a 12- to 16-cent-per-watt tariff overall already and that's before the new module-level tariffs have been factored in. (...) The second storm cloud that Clifford sees brewing is the battle between utilities and solar. He said that utilities see solar as a threat and have not yet begun to do the work involved in adapting to a changing electricity market. (...) The extension of the ITC is the third major storm cloud that awaits the industry, said Clifford.
