- Mississippi Net Metering Rules Advance
Mississippi, one of the last states that have not created a net metering policy, might soon have a rule created. On Tuesday, the state Public Service Commission (PSC) voted unanimously to issue rules that will create a framework allowing customers to install rooftop solar and sell excess electricity to their utility company. Public comments are due
- Australia?s Biggest Power Producer Sees Future without Coal
Australia?s largest electricity producer committed to close its coal-fired power plants within 35 years as part of an effort to cut the nation?s dependence on the fossil fuel.
- Bonded PV Arrays Could Provide Safer Solar Power
Most electricians are referred to as ?indoor wiremen? and are experts at installing electrical equipment indoors, but some lack experience working with exposed cables and outdoor equipment bonding. Traditional methods of bonding and grounding include the extensive use of bare copper conductors for equipment bonding. While copper is preferred for bonding steel, it is not the best choice around exposed aluminum members. Aluminum and copper should not come into direct contact due to galvanic corrosion issues. Over time, copper has a tendency to erode aluminum and can even cause structural failure of thin aluminum extrusions when in direct contact.
- Brazil to Offer Ambitious Climate Plan With More Renewables
Brazil will increase the use of renewable energy, target zero net deforestation and push for low-carbon agriculture as part of its climate proposal, Environment Minister Izabella Teixeira said in an interview.
- North Carolina Renewable Energy Standard Attacked Again
After using last year?s legislative session to deal witháDuke Energy?s Dan River coal ash spill, Republicans on the House Public Utilities Committee are bringing back their 2013 attempt to freeze the state?s Renewable Energy and Energy Efficiency Portfolio Standard (REPS). Representatives Millis, Hager, Collins, and Warren introducedáHouse Bill 681
- Negotiating the Energy Balance in the Caribbean
Reflecting the azure skies of the Caribbean, solar panels on private houses, hotels and businesses are an increasingly common sight across all the islands. Many Caribbean customers are seeking a degree of energy independence, which is not surprising given that many pay five or six times as much for their grid-provided electricity than their neighbours in mainland USA.
- Measuring the Effects of Utility-Scale Solar Growth
For so long it seemed like a pipe dream, yet in less than a decade utility-scale solar has reached $100 billion worth of capacity. Figures from the Energy Information Administration show that it delivered 5 percent of California's electricity in 2014. The time has come to evaluate the impact which this technology can have, not just in the United States but globally.
- Solar Flux Solution Brightens Future of Concentrated Solar Power
Power tower solar has been under a cloud ? in the U.S., anyway ? after 321 birds or bats were killed in the first 6 months of operation by flying through solar flux above the Ivanpah Concentrated Solar Power (CSP) plant, the Google-funded colossus in California?s Mojave desert.
- Fossil Fuels Just Lost the Race Against Renewables
The race for renewable energy has passed a turning point. The world is now adding more capacity for renewable power each year than coal, natural gas, and oil combined. And there's no going back.
- Can Other Cities Match Georgetown?s Low-Cost Switch to 100 Percent Wind and Sun?
This is probably not the first place you?ve read about Georgetown, Texas, the town of 55,000 that will be getting the equivalent of 100 percent of its electricity from renewable energy by 2017. But few articles hit upon the two key reasons Georgetown was able to make this move when so many other cities with abundant renewable resources (e.g. Tucson
- The Dark Horse in the Global Solar Race: India?s 100-GW Solar Ambition
A "dark horse" is defined as a little-known entity that emerges to prominence in the face of competition ? a contestant that seems unlikely to succeed. I borrow the term from a conversation last week, wherein India was referred to as the dark horse in the global race to go solar.
- Prepaid PPAs: Nice, but ?Nichey?
For commercial and small utility-scale solar, the prepaid PPA is a great idea ? in theory. By prepaying for expected generation over the contract term, the long term price that the offtaker pays for electricity can be much lower. Assuming the offtaker can find the cash to handle the large prepayment, these deals can increase IRR, lower an offtaker?
- Gates, Pritzkers Take on Musk in $5 Billion Race for Battery Storage
Professor Donald Sadoway remembers chuckling at an e-mail in August 2009 from a woman claiming to represent Bill Gates. The world?s richest man had taken Sadoway?s Introduction to Solid State Chemistry online, the message explained. Gates wondered if he could meet the guy teaching the popular MIT course the next time the billionaire was in the Boston area, Bloomberg Markets magazine will report in its May issue. ?I thought it was a student prank,? says Sadoway, who?s spent more than a decade melting metals in search of a cheap, long-life battery that might wean the world off dirty energy. He?d almost forgotten the note when Gates?s assistant wrote again to plead for a response.
