EU Leaders Agree To Tough Carbon Regulations to Spur Renewable Energy Development and Fight Climate Change

Mon, 10/27/2014 - 07:51

European Union leaders backed the most-ambitious carbon emissions goals of any major economy, in a bid to crank up pressure on the U.S. and China ahead of climate talks in December.

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

Mon, 10/27/2014 - 06:49

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.

SolarCity Broadens Its Financial Reach in the Barely Tapped Residential Market

Fri, 10/24/2014 - 09:51

Residential solar has soared in the past several years, with installation demand expected to soon surpass 1 GW of capacity. Much of this growth is due to the introduction of solar leasing. SolarCity, a major player in the residential solar leasing space, recently introduced new mechanisms to get more customers on board the solar train, and was at Solar Power International this week to discuss where the industry is headed.

Australia Seeks to Reduce Renewable Energy Target to ‘Real’ 20 Percent

Fri, 10/24/2014 - 09:22

Prime Minister Tony Abbott’s government will negotiate with the opposition to cut Australia’s renewable energy target and exempt industries such as aluminum and copper smelting.

Viable Battery Backup for Rooftop Solar Still Years Away

Fri, 10/24/2014 - 09:11

Using batteries to retain energy from rooftop solar systems will be too expensive for at least two years, according to industry executives.

Suntech Back from Dead, Eyeing 1.5 Gigawatts in Solar Shipments

Fri, 10/24/2014 - 08:58

Wuxi Suntech Power Co., the solar manufacturer acquired earlier this year by Shunfeng Photovoltaic International Ltd., plans to ship almost twice as many modules this year, in the latest sign of a rebound.

Local Solar Rules Can Save You Big Bucks

Fri, 10/24/2014 - 08:52

The price of an average U.S. home solar power system is about $20,000. (That’s before a 30 percent federal tax credit and any state, local and/or utility incentives.) If the price were to drop to $17,000, or even $16,000, would you be buying?

Evaluating Powerful Batteries for Modular Grid Energy Storage

Fri, 10/24/2014 - 08:46

Sandia National Laboratories has begun lab-based characterization of TransPower’s GridSaver, the largest grid energy storage system analyzed at Sandia’s Energy Storage Test Pad in Albuquerque, N.M.

California’s Conservation Proposal Kneecaps Utility-scale Solar

Fri, 10/24/2014 - 08:35

Six years in the making, state and federal agencies released five options with a “Preferred Alternative” draft for the Desert Renewable Energy and Conservation Plan (DRECP), potentially kneecapping development in the best solar region in the U.S. by cutting off previous access to public lands and reducing eligible acreage by two thirds.

Renewable Energy Contractors Benefit from PACE Financing

Fri, 10/24/2014 - 08:03

One third of all energy is wasted. Is PACE the solution? According to current energy data, commercial and industrial buildings use about 60 percent of the energy generated in the U.S. and about a third of this energy, especially in older buildings, is wasted due to inefficiency. But how do we know which third, and what can we do about it? The answe

Designing Reliable, Cost-effective Wind Turbine Shaft Systems

Fri, 10/24/2014 - 07:48

A wind turbine’s main shaft requires a reliable bearing for operation. Some bearing designs have been known to fail prematurely resulting in costly maintenance repairs. Recent upgrades and advances in bearing designs increase reliability, and ensure main shaft stability. Selecting the proper bearing is beneficial to a wind turbine’s overall performance.

SPI Slideshow Day Three: Seen on the Tradeshow Floor

Thu, 10/23/2014 - 18:42

The last day of Solar Power International tends to be a little more casual. Exhibitors, exhausted from frenzied activity over the first two days, can take a step back and reflect a bit. Check out our slideshow for more scenes from the tradeshow floor.

Community Solar Allows Utilities to Adapt, Thrive as Energy Landscape Evolves

Thu, 10/23/2014 - 09:48

Adaptability is the key to survival — both in nature as Charles Darwin observed, and in the business sector. As the solar industry continues to flourish, utility companies across the U.S. are beginning to witness how the traditional electric grid is transforming. As tens of thousands of residents have solar photovoltaic (PV) panels installed on the

The Next Revolution: Discarding Dangerous Fossil Fuel Accounting Practices

Thu, 10/23/2014 - 09:43

The green revolution and, in particular, renewable energy products such as solar power, wind turbines, geothermal and algae-based fuels are not waiting for viable technology — it already exists in many forms. What they are waiting for is a massive sea change in our antiquated financial accounting systems.

Economists Say Curbing Climate Change Will Help Our Economy

Thu, 10/23/2014 - 05:37

It was great to see economists in two separate New York Times opinion pieces recently noting that controlling climate pollution may be economically beneficial rather than restraining growth, as conventional wisdom among economists has held.

US Energy Secretary Tours 6.4-MW Rooftop Solar Array in Las Vegas

A Tale of Two Booths: SPI Solar Event Marketing Hits and Misses, Part 1

Wed, 10/22/2014 - 08:36

“It was the best of times, it was the worst of times,” so Charles Dickens wrote, and the same might be said for Enphase and RECOM, two solar exhibitors that were across the aisle from each other at this year’s Solar Power International. I passed their booths several times, and every time I did, Enphase had almost wall-to-wall traffic, while RECOM’s
