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
Just one year after Greenpeace called out Apple for its use of fossil fuels in its “How Green Is Your Cloud” report – which graded Apple no higher than a “D” in four categories consisting of energy transparency, infrastructure siting, energy efficiency, and renewables and advocacy – Apple announced that its data centers are now powered by 100 percent renewable energy. In fact, renewables contribute to 75 percent of its entire corporate operations energy needs, according to its website.
Short of putting a windmill on top of a car – a parody vehicle that became a source of political jesting during the 2012 U.S. presidential election – electric vehicle (EV) owners have little control over the ultimate emissions profile of their cars. An…
As the renewable energy industry grows and becomes a larger part of our energy mix, the concept of energy storage has made its way into the spotlight and has created some important pressing questions: Do renewables’ inherent intermittency require some …
I’m a reader. I love sitting down with a great book or an in-depth report full of charts and graphs and really digging in. SEIA and GTM Research just released their Solar Market Insight Report with staggering figures about solar installations in the U.S. in 2012. If you, like me, love to learn about the global growth of renewable energy, you shou
With policy focus, creative use of technology, and good management, minigrids can deliver 100 percent electrification for the ~1.5 billion mostly rural people worldwide — affordably, without global warming emissions, and within ten years. In urban deployments, renewables-powered minigrids will de-stress the electricity infrastructure. A whole new business is poised to launch. The time to begin is now.
While the State of New York hashes out deep disagreement over how to deal with sugary megadrinks that contribute to obesity, maybe they can turn their attention to something a little less complicated — like mapping a full conversion to 100 percent renewable energy in less than 20 years.
As the low-emission economy evolves, building new generation technologies is just half the challenge. The other half of the challenge lies in building the transport and distribution networks – and Asia is the region to watch, specifically China, Japan, South Korea, the Association of Southeast Asian Nation (ASEAN) States, East Timor and Australia.
