The project will include 4.88 MW of solar panels. Its battery system will store energy and discharge up to 2.6 MW during peak hours
Supercapacitors have been compared to the flash from an old camera. They give an immediate burst of energy, which is then gone. A number of companies have combined supercapacitors with batteries for applications that require immediate response and sust…
Ernie Moniz has been unanimously confirmed by the U.S. Senate as the next Secretary of Energy, in a 97-0 vote (with three nonvoters). He succeeds Stephen Chu who held the position for four years.
In the past, a PV system with battery storage was associated with the off-grid system — not connected to the utility grid. The battery stores the energy produced by the PV system and when the sun goes down, electricity is drawn from the battery. In Japan, the battery became attractive to store electricity from “the grid,” to reduce electricity bills.
It’s always the same problem: You save energy but the electricity bills are still getting more expensive. Luckily, there is a solution: Solar power can be generated in Germany for 12 cents per kilowatt hour. In contrast, utilities currently charge an average of 25 cents for domestic electricity. What better reason to invest into your own photovoltaic system? Solar storage systems can increase on-site consumption by up to 70 percent. They absorb surplus solar power and pass on the energy as required — expensive grid power is hardly necessary. This makes the systems very attractive for consumers: According to an EuPD Research survey, almost 90 percent of solar operators are already thinking about buying an additional storage system.
Global expectations for hydrogen are currently sky-high. Transport applications stand at the threshold of commercialisation, while ahead lies an investment boom in the hydrogen distribution network. The changeover to hydrogen based on natural gas would…
Europe’s program to halt climate change is in disarray with lawmakers in the region expressing concern the drift is undermining the planet’s most significant effort to combat global warming.
Solar and wind are excellent sources of clean, renewable energy, but as they contribute a larger share to the generation fleet, their integration will become increasingly challenging. The reason: solar and wind cannot be dispatched in the same way as other sources of energy, such as nuclear, hydro, and fossil fuels. Because the grid must operate “j
Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.
China’s solar PV demand sunk 23 percent in 1Q13 to 6.2 gigawatts (GW), driven by seasonality and policy incentive deadlines. Chinese demand largely drove a burnoff in upstream inventory accumulated over several quarters, but repetitive swings in Chines…
A recent IRS ruling confirms that batteries used to store solar electricity qualify for the 30% energy tax credit. At the same time, it imposes significant limits on the amount of the available credit if the battery also stores electricity drawn from …
Germany will subsidize consumers’ purchases of battery systems to store power from solar panels through a 25 million-euro ($32.6 million) program to promote wider use of renewable energy, according to the German Solar Industry Association.
Today in New Delhi the International Energy Agency (IEA) revealed the latest figures from its annual report on global progress towards a low-carbon future. The agency addressed its report to a meeting of the Clean Energy Ministerial, a group of ministe…
A recent European Commission Green Paper seeking views on the development of intermediate renewable energy and climate targets for 2030 has prompted calls from the industry to adopt a three part approach, targeting renewable energy, energy efficiency and emissions reduction. Formally opening an ongoing debate, the consultation — the Commission says
NRG Energy keeps making waves—in energy. The energy supplier, which owns gigawatts of electric generation, including solar, wind, natural gas and coal facilities across the U.S., recently started going a lot smaller, offering residential solar photovoltaic installations through its subsidiary, NRG Residential Solar. Now it plans to offer PV systems
We’re losing the race against global warming. Worldwide coal production increased about eight times faster than solar- and wind-power generation last year. China added more new coal plants in 2011 than are running in Texas and Ohio, even as it leads th…
It’s almost a cliché that there’s a “friendly debate” pitting utilities against renewable energy. But concerns on the utility side of the table are real: intermittency, potential destabilization at the feeder level, non-baseload, and peaks in generation that don’t necessarily match demand peaks. Today’s power infrastructure involves unpredictability in both supply and demand that is extremely difficult to manage. The choice comes down to two options: over-generate so as to not undersupply, or find ways to better match up supply and demand.
RenewableEnergyWorld.com has learned of secret meetings that have been held between UN energy ministers and Martian ministers of energy regarding the terawatts of easily exploitable geothermal energy that Mars possesses.
In response to a statutory review, The Australian Government’s Climate Change Authority has committed to maintaining its renewable energy target (RET) of 20 percent of the nation’s electricity (roughly 41,000 GWh) coming from renewable sources by 2020….
The good news is the Department of Energy (DoE) FY 2013 budget request of $2,337 million for Energy Efficiency and Renewable Energy programs (EERE) shows a 29 percent increase from the enacted FY 2012 budget. The bad news is the FY 2013 has not been approved by Congress, as of this writing, see Table 1 below. Table 1: FY 2013 DoE Budget Request
