From ThinkProgress: A new study by the NC Clean Energy Technology Center finds that in all but 4 of the 50 largest cities in the U.S., installing a fully-financed 5 kilowatt solar panel system makes more financial sense than investing in a popular stock market index fund. Further, the same system would beat the costs of buying energy from local utilities in 42 of those 50 cities. “(S)olar is now not just an option for the rich, but a real opportunity for anyone looking to take greater control over their monthly utility bills and make a long-term, relatively low-risk investment,” concludes the study which was done under funding by the U.S. Department of Energy. A key qualifier in this good news study is that the benefits of installing residential solar photovoltaic systems are greatest when homeowners finance the systems (at an assumed annual interest rate of 5 percent) rather than buying them upfront. And the study does not investigate the availability of such loans. The study finds that in upfront purchases of solar, residents in just 14 out of the 50 largest U.S. cities would pay less for electricity than if they buy from their local utility. That upfront investment would be a better investment than the broad stock market index fund in 20 of the 50 cities. Cont'd....

Rather than focus on any one particular technology, the EFST training course educates the participants about the common technologies and service requirements that touch multiple markets, most notably the solar and electric vehicle charging equipment infrastructure.
2015 promises to be another banner year for the Renewable Energy Industry. Solar and Wind will continue to grow and Energy Storage will continue to dominate the conversation. April offers up some great Energy Storage events here in North America and Europe.
Gov. Jerry Brown's proposal this week to significantly boost the amount of energy California derives from renewable sources could reinvigorate the state's utility-scale solar and wind industries, as well as launch another land rush in the Mojave Desert. In his inaugural address, Brown didn't say how the state's Renewables Portfolio Standard could be raised to 50% by 2030 — the previous benchmark was 33% by 2020 — but his commitment was clear: "This is exciting, it is bold, and it is absolutely necessary if we are to have any chance of stopping potentially catastrophic changes to our climate system," the governor said. He also outlined a plan to reduce petroleum use in cars and trucks by 50% and double the energy efficiency of new buildings in the state. The reverberation was instantaneous. "Is it significant? Absolutely. Will it stimulate the market? Absolutely," said Jerry R. Bloom of the Los Angeles law firm Winston & Strawn, who guides renewable energy developers through the financing and permitting processes.
World clean energy investment rebounded strongly in 2014, boosted by demand for large-scale and rooftop solar photovoltaics on the back of its greatly improved competitiveness, and by the financing of a record $19.4bn of offshore wind projects. Authoritative annual data, published today by Bloomberg New Energy Finance, show that global investment in clean energy was $310bn last year. This was up 16% from a revised $268.1bn in 2013, and more than five times the figure of $60.2bn attained a decade earlier, in 2004, albeit still 2% below the all-time record of $317.5bn reached in 2011. The jump in investment in 2014 reflected strong performances in many of the main centres for clean energy deployment, with China up 32% to a record $89.5bn, the US up 8% to $51.8bn (its highest figure since 2012), Japan up 12% to $41.3bn, Canada up 26% at $9bn, Brazil up 88% at $7.9bn, India up 14% to $7.9bn, and South Africa up 5% at $5.5bn. Europe, despite the flurry in offshore wind, was a relative dull spot overall, investment there edging 1% higher to $66bn.
The United Kingdom blew past previous wind power records in 2014 while Germany generated a record amount of electricity from wind in December, setting the stage for 2015 to bring more industry growth across Europe. Exactly how quickly it grows, however, is contingent upon several political and regulatory decisions to come. Using statistics from the U.K.’s National Grid, the trade association RenewableUK found that wind generated enough electricity to power just over 25 percent of U.K. homes in 2014 — a 15 percent increase from 2013. Wind turbines provided 9.3 percent of the U.K’s total electricity supply last year, a 1.5 percent boost from 2013. “It’s great to start 2015 with some good news about the massive quantities of clean electricity we’re now generating from wind,” said RenewableUK’s Deputy Chief Executive Maf Smith. In December, Germany generated more wind power, 8.9 terawatt-hours, than in any previous month. According to the IWR renewable energy research institute, this record will be overtaken in 2015 as more offshore wind farms come online.
The world will need as much capacity as it can get from all fuel sources to satisfy the demand of growing populations.
Knowing how your batteries operate in cold weather conditions can greatly help you keep track of your battery packs' health, and more importantly allow you to maintain your power needs when you need it most.
It's an exciting time to be in the solar industry, both for what we've accomplished in 2014 and what we will accomplish in the coming year.
Because the materials involved are inexpensive and the fabrication is simple, this approach has the potential to be scaled up for production at commercial levels.
According to TMR, the global green energy market will reach a value of USD 831.99 billion by 2019.
ydney-based energy investment group Tag Pacific has today announced it has won a landmark deal to deliver Australia’s largest energy storage system to be operated alongside the University of Queensland-owned Gatton solar power plant in south-east Queensland. The battery storage project, valued at around $2 million, was won by Tag’s wholly owned power business MPower, which is also working with Rio Tinto and First Solar in the remote town of Weipa, Queensland, to build an ARENA-supported 1.7MW solar PV project, which will serve a remote bauxite mining operation and could be expanded to 6.7MW The newly announced energy storage project, will be grid connected; a slightly different tack for MPower, which has tended to specialise in remote, and off-grid solar plus storage hybrid systems.
Some people complain that solar panels and wind turbines are so unattractive, they’d prefer not to see them at all. To them we offer New Wind, alternative energy generators that look like trees. The 36-foot-tall steel structure is perfect for urban environments, where a conventional wind turbine might not fit. Seventy-two artificial leaves that work as micro-turbines adorn the branches and spin silently on a vertical axis. Cables and generators have been integrated into the leaves and branches in a way that puts them out of sight and sound. The beautiful and functional device is the brainchild of French entrepreneur Jérôme Michaud-Larivière, who said the idea for a tree-inspired wind generator came to him one day while sitting in a square, watching the leaves on nearby trees tremble in a breeze. He wondered if energy could be generated in a similar way. Indeed, it can. At the moment, each tree has a power output estimated at 3.1 kW.

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
