One of the best sources for these stories is "Thoughts on Solar," a blog written regularly by Jim Jenal. Jim is the CEO of Run on Sun, a residential and commercial installer based in Pasadena, California. I had the pleasure of having Jim as my guest on the Energy Show, and most of what we talked about related to reliability of rooftop systems, and the reputation of the solar industry itself./p

Can Gigawatts of Geothermal Save the Salton Sea?

img hspace="10" vspace="5" align="left" src="http://www.renewableenergyworld.com//assets/images/story/2014/3/14/feature-0-1394829377231.jpg" /pFamously known for its rise and fall as a resort destination in the 50s and 60s, The Salton Sea area in California has struggled to find support for revitalization efforts. After all, the lake’s high salinity makes it nearly impossible for sea life to prosper, and as water levels continue to diminish, the exposed sea floor further contaminates the arid, stale air. However, there is one industry that is eager to take advantage of what seemingly little the area has to offer — geothermal. Under the surface of that toxic seabed are thousands of megawatts of potential. /p

Renewable Energy Brings Out Some Extreme Nimbyism

These are people who spend a large portion of their time preparing themselves, their homes and their families for what they believe is an inevitable disaster resulting from an economic meltdown, the spread of a deadly virus, climate change or another catastrophic event.  And hey, you never know, in the end th/p

California Flexes Its Solar Muscles

img hspace="10" vspace="5" align="left" src="http://www.renewableenergyworld.com//assets/images/story/2014/3/14/feature-0-1394822017699.jpg" /pAt 1:41 PM on Saturday March 8, California hit a new record of solar energy output of nearly 4.1 GW. That narrowly beat out the previous record of 3.9 GW, which was set the day before. It's also more than double the peak solar output from last June, and quadruple the output from the summer of 2012. Coincident demand for the new record was about 22.6 GW, meaning at that peak solar served about 18 percent of demand, roughly enough to power three million homes. All of that data is from California ISO (CAISO), which reported the new mark earlier this week./p

Meet Solar’s Imaginary Friend, Reactive Power

Real power does the actual work when you flip on a light switch.  Certain energy loads, such as motors and refrigerators, include energy storage elements that periodically need to reverse the direction of energy flow. This electric power /p

And the Future of Residential Solar Is…Up for Grabs

From financing models, solar leases, community (group buy) to owners of multi-unit housing complexes potentially becoming independent power producers, there is a changing of the business model guard. Think of it, the world may be a major storage innovation away from disconnecting from the utility grid. Do not kid yourself, there will be utility pushback but there will also be utility participation in the vein of, if you can’t beat ‘em, join ‘em. /p

They think the solar buying public won’t take them seriously as reliable solar installers. But is that really the case? I’m happy to say that at le/p

How Geothermal Heat Pumps Can Soar Like Solar

Unfortunately, many people take it literally. GHPs have all the hallmarks of a better mousetrap: They do the job of heating and cooling a building more efficiently than any other option. Despite the larger up-front cost, they are a mature technology and usually the most economic option for buildings that can accommodate them./p
