Today an increasing amount of intermittent PV electricity is being pumped into the grid. As grid capacity nears its limits, the issue of grid compatibility is gaining in significance. Solar-farm owners must prove that - once connected to the electricity grid - their plants will behave in the same manner as conventional power stations have done for years. Failure to ensure solid preparation of the comprehensive certifications required in this context may delay the launch of service for their solar power system.
Our Intelligent Solar Information System (ISIS) provides industry-leading monitoring, diagnostics, reporting, and control of solar power plants.
Structural batteries are sheets of carbon-composite material that can be molded into complex 3-D shapes to form the actual structure of a device. Thus, the rear wing of a racing car becomes an in-built battery, a torch is its own power source, and the fabric of a tent can capture solar energy.
Bombardier, a global leader in aerospace and rail transportation is inviting people to submit ideas for sustainable mobility in the urban environment.
Donald Trump swept into Scotland's parliament on Wednesday to demand the country end plans for an offshore wind farm he fears will spoil the view at his exclusive new $1.2-billion golf resort. In a typically blunt display, the property tycoon told an inquiry into renewable energy to stop the wind power efforts in the country's north. "Scotland, if you pursue this policy of these monstrous turbines, Scotland will go broke," he said. "They are ugly, they are noisy and they are dangerous. If Scotland does this, Scotland will be in serious trouble and will lose tourism to places like Ireland, and they are laughing at us." When challenged to produce hard evidence about his claims on the negative impact of turbines, Trump said: "I am the evidence, I am a world-class expert in tourism." The public gallery burst into laughter.
This project has been developed by Gujarat State Electricity Corporation Limited (GSECL), with full support from Sardar Sarovar Narmada Nigam Limited (SSNNL) which is the nodal agency behind construction of the Naramda canal that brought agricultural prosperity to the State. The engineering, procurement and construction contract for the project has been awarded to Sun Edison, a subsidiary of US-based global solar energy player, MEMC. The 750 metre stretch of the canal will generate 1.6 million units of clean electricity per year, as well as prevent evaporation of 900,000 litres of water per year from the canal. Today, Gujarat has about 458 kilometres of open main canal, while the total canal length including sub-branches is about 19,000 kilometres; the final aim of SSNNL is to construct a total of 85,000 kilometres of canal network. Assuming a utilization of only 10% of the existing canal network of 19,000 kilometres, it is estimated that 2,200 megawatts of solar power generating capacity can be installed. This implies that 11,000 acres of land which would otherwise be needed to site solar panels as well as 20 billion litres of water per year can be potentially conserved.
The outlook for US wind power growth is cloudy and negative with the wind production tax credit (PTC) due to expire at year-end. The wind power forecast for 2012 is decidedly better north of the US border, in Canada, however. Canada’s wind power market should experience another year of record-setting growth in 2012, with the addition of some 1,500 MW of additional capacity, according to a Canadian Wind Energy Association (CanWEA) study released at the Global Wind Energy Council (GWEC) annual conference in Copenhagen. Canada’s wind energy industry enjoyed a record year in 2011, installing around 1,267 MW of new capacity, an investment of $3.1 billion that created some 13,000 person-years of employment. That ranks 6th globally with a total wind energy capacity of 5,403 MW, enough to power more than 1.2 million homes, according to CanWEA and the GWEC’s 2011 annual industry reports.
Data centers guzzle down 2% of the electric grid’s capacity and run up $2 billion worth of monthly utility bills. Furthermore, it’s estimated that by 2020, CO2 emissions from data centers will top the emissions by the airline industry. How do we get the cloud under control? One solution might be improving the efficiency in how data centers draw electricity in from the grid. A recent post from GE Reports takes a look at how 99% of this electricity could be pulled in more efficiently by bypassing ‘filters’ when they’re not absolutely necessary. If all data centers (‘the cloud’) did this, we’d be able to save 4,000 megawatts of electricity worth more than $3 billion per year.
The U.S. wind industry installed 6,816 megawatts (MW) in 2011, 31 percent higher than 2010, for a total of 46,916 MW installed to date, the industry's trade group said in a release Thursday. Setting the stage for a strong 2012, the American Wind Energy Association (AWEA) also said there were more than 8,300 MW of wind power under construction across the United States. The nation has about one million megawatts of generating capacity with about 400,000 MW coming from natural gas burning plants, 300,000 MW from coal, 100,000 MW from nuclear, 80,000 MW from hydropower, 50,000 MW from oil and the rest mostly from wind and other renewables. One megawatt powers about 1,000 homes. Wind and natural gas are the two largest sources of new generating capacity in the United States. Wind has provided about 35 percent of new U.S. power capacity over the past five years, AWEA said. Full Article:

There is currently no single solution that is better than another for all situations, but lithium-ion systems offer better cost of ownership in a number of situations, specifically hot climates, despite the higher initial cost.
In pursuing its brave new world of green energy, California will inevitably experience the vicissitudes of its pioneering undertaking - the twists and turns on the road to TLC (transparency, longevity, certainty)
Innotech Solar optimizes off-spec cells
Two years ago, the New Jersey Army National Guard asked the Army Corps if it could construct a solar power project so they could save energy and money as they had done for them on previous solar power projects.
With the elimination of federal incentives for renewable generation, more than $20 billion may be shifted from the federal level (i.e. all taxpayers) to the customers in states with RPS targets.

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.
