Suzlon in Talks for Japanese Offshore Wind Partner

Fri, 08/22/2014 - 08:55

India’s Suzlon Energy Ltd. may seek a Japanese partner to make offshore wind turbines, attracted by access to cheap yen loans as projects at sea get costlier and more complex.

Countdown: What Are the Top 10 Solar States in the US?

Fri, 08/22/2014 - 06:33

The Environment America Research & Policy Center has released its annual report ranking the top 10 U.S. states with the most cumulative solar electric capacity installed per-capita.

Would You Rather Own or Lease Your Rooftop Solar?

Fri, 08/22/2014 - 03:38

On a recent trip to Australia, I noticed that very few residential solar systems are leased. The vast majority are customer owned. Talking to industry experts, some claimed more than 90 percent of residential solar systems in Australia are customer owned. This is in stark contrast to the U.S., where last year 66 percent of residential solar is leased from third-party owners like SolarCity. Why such different approaches to ownership of residential rooftop solar?

South Africa Approves Treaty for $100 Billion Inga Hydropower Project

The Next Big Challenge for Energy Storage

Thu, 08/21/2014 - 06:29

The energy storage era is upon us. States like California and New York have adapted energy policies that will make it possible to economically deploy storage systems, while technology advancements have boosted performance and trimmed costs. For the first time in history it will become feasible to store electric energy.

Listen Up: What's the Deal with Solar Trackers?

Thu, 08/21/2014 - 05:55

In the early solar PV days, trackers were a necessity to maximize the energy output from very expensive solar modules. Unfortunately, in those days trackers were mechanically complex and unreliable (remember TV antenna rotors?), and the control systems were expensive and finicky. As solar module pricing declined, the interest in trackers for small systems began to wane.

Renewable Energy Accounts for 100 Percent of New US Electrical Generating Capacity in July

Thu, 08/21/2014 - 04:31

According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, all new U.S. electrical generating capacity put into service in July came from renewable energy sources: 379 megawatts (MW) of wind, 21 MW of solar, and 5 MW of hydropower.

NRG Just Purchased a Consumer Solar Gadget Company. Can You Make the Same Solar Marketing Play?

Wed, 08/20/2014 - 07:01

By now you’ve probably heard the news that pro-solar energy giant NRG is purchasing Goal Zero, a relatively tiny solar consumer electronics company. But why? NRG is a huge residential and utility scale solar integrator, while Goal Zero sells enough solar PV to power maybe a single NRG utility project. Of course, the answer is that NRG isn’t buying

Lubricating Energy Policy

Wed, 08/20/2014 - 06:09

The new report from the Taxpayers for Common Sense shows that oil companies paid just 11.7 percent of their U.S. income in federal taxes over the last five years, and the “smaller” companies included in the study that reported positive earnings only paid 3.7 percent. To achieve such a low tax rate, oil companies were able to take advantage of special tax breaks and loopholes that allowed them to defer more than $17 billion in taxes they would have otherwise owed.
