Listen Up: An Architect's Perspective on Rooftop Solar

2 hours 49 min ago

Architects are in the driver's seat when it comes to building new homes or overseeing major remodeling projects. Although they are familiar with rooftop solar, their designs generally do not include solar panels. Whether it's because of cost, technology or aesthetics, it's a big opportunity that is lost to almost all new homeowners.

SolarWorld Boosts Manufacturing in Oregon

Thu, 10/30/2014 - 18:48

U.S. solar panel industry leader SolarWorld today announced plans to increase capacity from 380 MW to 530 MW, and to boost advanced cell manufacturing capacity at its Hillsboro, Oregon plant by 100 MW, adding 200 jobs at the location, which will grow to 900 employees. The Bonn-based company also manufactures in the German cities of Freiberg and Arnstadt. “The factory will remain the largest of its kind in the Western Hemisphere. The company views this expansion as a stepping-stone to 630 MW capacity in the near future,” SolarWorld said.

German Experts Lock Horns over Storage

Thu, 10/30/2014 - 15:29

Could the Upcoming Election Decide Florida’s Renewable Energy Fate?

Thu, 10/30/2014 - 15:29

As gubernatorial candidate Charlie Christ noted in the recent debate, the corrupting influence of Florida’s electric utilities has blocked efforts to help Florida transition into a fair and free-market renewable energy economy. The impact of this powerful fossil fuel lobby has been demonstrated as they funnel resources to influence the outcome of the Florida governor’s race. Renewable energy, in particular solar energy, will without a doubt have a significantly positive economic impact on Florida’s natural and economic environment. But the first step for the Sunshine State is a changing of the guard in the executive office.

Part 2: SPI 2014 Solar Event Marketing Hits and Misses

In part 2 of my annual solar event marketing hits and misses, we’ll explore some more specific hits and misses that I found on the Las Vegas SPI show floor. First of all, although final numbers haven’t been released, SPI 2014 seemed to be very well attended. The floor looked crowded and exhibitors that I talked to said that booth traffic was much i

Are Environmental Regulations Causing US Utility Bills to Surge?

Wed, 10/29/2014 - 15:08

U.S. electricity markets face years of higher prices as clean-air regulations shut more coal-fired power plants than earlier forecast, cutting supply and forcing producers to rely more on natural gas.

From Ashes to Energy: $1 Billion Alevo Battery Factory Surges On the Scene

Tue, 10/28/2014 - 14:27

Having worked in stealth mode for the past 10 years, German researchers in combination with serial entrepreneur Jostein Eikeland have developed a new battery chemistry that they claim is non-combustible and highly efficient. The batteries, say Alevo, have at their core a new inorganic electrolyte that eliminates “both the risk of combustion and explosion and massively reduces the debilitating effects of charging cycles.”

Why Is an Island Electric Utility Hindering Incredibly Cost-Effective Solar?

Mon, 10/27/2014 - 19:11

The Northern Mariana Islands are one of several island U.S. territories, lying three-quarters of the way from Hawai’i to the Philippines. Like most islands, their electricity supply has been almost entirely supplied by diesel-fueled generators, at enormous cost. So why have islanders in the Marianas — such as the residents of Saipan — been struggli

SolarWorld To US Solar Developers: “We Want the Same Things”

Mon, 10/27/2014 - 13:49

When Rhone Resch opened Solar Power International 2014 by telling the industry that it needs to fight for solar the same way that the Koch Brothers fight for coal, he probably wasn’t thinking about SolarWorld and its fight with China over what it says are unfair manufacturing subsidies. But, at least according to Ben Santarris, Strategic Affairs Director for SolarWorld Americas and Tim Brightbill of the law firm WileyRein, fighting for its industry is exactly what SolarWorld is doing.
