Entrepreneurs work to bring solar benefits to the 300 million citizens who lack electricity.
The sun is shining on India, and India is poised to take advantage of it, with massive investments in solar energy facilities to help meet the needs of a population that is expected to grow to make it the planet's most populous nation by 2022. But will the power go to the people who need it most?
A recent study by Deloitte and the Confederation of Indian Industry estimated India's solar power potential at 749 gigawatts - nearly three times the country's entire installed electrical capacity in 2012 - and reported that not even 1 percent of this potential is currently tapped.
Air France said on Wednesday that negotiations with representatives of its pilots over its "Perform 2020" restructuring plan had failed.
Air France, part of Franco-Dutch airline Air France-KLM (AIRF.PA), said in a statement: "The many hours of talks and negotiations, closely followed by the chairman and CEO of Air France, could not yield, within a reasonable timetable, an agreement insuring the growth and competitiveness of the company."
Pol Bacquet's insight:
Maybe the solution is to switch to KLM - Air France and be less arrogant for keeping alive such a company !...Remember Pan Am ! Remember Eastern !.... Remember TWA ! .... Remember Swissair !... as they were all having glorious days and passed away. Unless Air France is sold to Qatar !!
A number of significant projects are now blending solar energy and battery storage at the utility scale.
In May, when Tesla Motors announced its new battery product to vast media buzz, the talk was all about people putting batteries in their solar-powered homes, and thereby becoming that much less reliant on the grid.
But there was always another and perhaps even bigger side of the story — the idea that very large scale batteries or battery packs could help out the grid itself by storing large amounts of solar energy for use in the evening or at night. The ultimate effect might be to displace electricity generated from coal or natural gas, and convert an inherently “intermittent” renewable energy source — solar — into a more constant one.
An analysis carried out by JRC scientists shows that the uncertainty in measurement of power generation from a photovoltaic (PV) cell can be more than halved, thus bringing an economic benefit to both manufacturers and investors. With the annual world PV production exceeding 40 GW in 2014 and a market value of over €25bn, this is good news for customers, utilities, the production industry and future R&D efforts in the field of renewable energy.
A team of researchers from Stanford University have devised an ingenious means of boosting the efficiency of solar panels by exploiting a fundamental physics phenomenon. Solar panels lose efficiency as they heat up. Just as the top of your head radiates excess body heat as infrared light, the researchers have developed a translucent overlay comprised of patterned silica that does the same for solar panels. The overlay separates the visible spectrum of light (which generates electricity) from its thermal radiation (aka heat), effectively "cooling" the incoming light, radiating the heat away from the panel while allowing more photons to be converted into electricity.
Solar power is approaching a “crossover point” where it makes sense for investors to back rays over coal, oil and gas, according to the head of oil major Royal Dutch Shell.
Amid tumultuous oil markets and tumbling costs as photovoltaic cells are rolled out globally, the value of solar is already evident in the world’s sunniest places, Ben van Beurden told BBC’s Radio 4 on Thursday.
Sunlight can be used to generate electricity either through a photovoltaic effect, or by harnessing the heat produced by the light. There are already hybrid systems that combine both, but scientists have now developed a type of hybrid setup that they claim works better.
When exposed to sun-like full-spectrum light, the photovoltaic cell absorbed some of the light and used it to generate electricity. The light that wasn't captured by the cell, however, proceeded through to the PEDOT film, causing it to heat up. The pyroelectric film and the thermoelectric device then utilized that heat to produce more electricity.
Solar panels are the future of alternative resources to reduce the greenhouses gases in atmosphere. Now, it could also become the best energy resource of humanity. Scientists discovered a new technique that would level up the efficiency of solar panels.
As solar nears grid parity, energy utopians’ dream of a panel on every rooftop looks increasingly probable. But in the recent words of Martin Sheen, we are a species that “invented the automobile and then invented an automobile that could drive over 20 other automobiles.” Human ingenuity being what it is — and solar cells dropping in price as they are — we won’t be stopping at rooftops.
Green aviation innovation is alive both at major industry players as well as smaller firms that have moved into this sector of research and development.
Today, we wanted to recognize a collection of innovators who are making strides forward in the race to develop cleaner jet fuels and greener modes of transportation. In the coming years, many of our readers may be airborne on planes operating on no fossil fuel whatsoever, or if they do, it’s likely produced from a biomass feedstock that does not require dipping into the world’s oil reserves.
Solar energy in the United States has seen immense momentum throughout the years. When the Solar Energy Industries Association released its annual report in 2008, it concluded that U.S. solar photovoltaic (PV) capacity reached a total of 1.183 gigawatts — a stellar achievement at the time.
Early adopters of rooftop solar and electric cars are finding a new obsession in energy storage as the first generation of consumer-friendly batteries capable of supporting household circuits comes to market.
Two new solar powered windows are on their way out of the laboratory and into the marketplace, making buildings more self-sustaining and eco-friendly.
Solar powered windows that generate electricity without spoiling the view? That’s the stuff of science fiction, right? Not anymore. Two groups of researchers — one in the US and another in Italy — have created functioning prototypes for solar powered windows that look clear but harvest electricity from the sunlight passing through them.
If solar energy is going to be the dominant force some thing it can be, it needs these technologies to work as advertised.
Today, the world tends to look at solar energy with a fairly narrow view. Solar companies put up solar panels on roofs, in fields, or in deserts and send electricity to the electric grid. That energy is intermittent, depending on when the sun is out, and fundamentally can't provide a base source of electricity for the grid.
But why does the view of solar energy need to be so narrow? Why not rethink energy as we know it, creating energy when it's cheapest and saving it for the time it's demanded by the market? That's where energy storage comes in.
Africa is a continent with abundant sunlight but has poor electricity grid coverage. Yet access to electricity is essential to run medical facilities and secure access to health care, especially in remote areas.
"Africa still makes little use of solar power in the health sector. This is a missed opportunity to safely store drugs. By investing in renewable energy, we could improve the quality of health care and reduce the large operating costs. We could also minimize the health care-related carbon footprint" said Blaise Karibushi, Global Fund project manager at UNDP Zambia.
September 22 (SeeNews) - In an earlier article Sven Lindstroem, co-founder and CEO of Swedish thin film solar technology firm Midsummer AB, challenged some of the most common myths about solar power. Here are five more:
MYTH 1: Cheap coal and the current energy mix (often dirty fossil fuel or nuclear) will continue to dominate global energy production for the foreseeable future. FACT: Don't bet on it.
The US Energy Information Administration’s new ‘Today in Energy’ brief looks at the slowdown in the growth rate of global solar panel production:
The brief shows that growth in solar photovoltaic (solar PV) module production has slowed in recent years to 4% annually from 2011 to 2013 after increasing by an average of 78% from 2006 to 2011. In addition, the gap between global solar PV module manufacturing capability and production has grown, leading to lower utilisation rates of manufacturing facilities.
Texas has just committed to its first ever grid-connected solar system with energy storage, courtesy of home-state solar experts OCI Solar Power and the global energy storage company Younicos. It’s a huge deal because the grid in question happens to serve 24 million Texans and other customers, accounting for about 90% of the electric load in the entire state.
Community solar projects offer those without rooftop panels a way to tap the sun’s power.
Many consumers would like to switch to solar power but can’t. It could be their homes have too much shade or their roofs can’t accommodate solar panels, or perhaps they live in a condominium or apartment building.
Enter so-called community or shared solar, which allows people to buy solar power from centrally owned arrays.
Massachusetts indeed should be applauded for its progress on solar power — but your Sept. 8 editorial, “Lift cap on solar power,” slights one point of the solar conundrum: what happens when the sun is not shining.
Electric utilities must somehow provide all the power required at those times, or we will all get pretty mad. Storage of excess solar power on an industrial scale just isn’t in the cards yet. In the future we might have better batteries, or we might overcome the political objections to pumped storage. But meanwhile we have to deal with the here and now.
The solar boom continues -- but growth could be impaired after 2016.
The U.S. solar industry is on course for a new growth record in 2015, according to a new report that finds that solar photovoltaic installations now exceed 20 gigawatts in capacity and could surpass an unprecedented 7 gigawatts this year alone across all segments. A gigawatt is equivalent to 1 billion watts and can power some 164,000 homes, according to the Solar Energy Industries Association (SEIA).
As renewable energy resources gain popularity and widespread applications, one company may provide the key innovation to take solar to the next level.
The ‘smart palm’ solar trees are nothing but tree shaped solar panels that are capable of generating close to 7.2 kWh per day of energy. The photovoltaic panels (with a leaf like shape) are capable of generating enough power to remain independent of the grid.
Researchers have wired four perovskite solar cells in series to enhance the voltage and directly photo-charged lithium batteries with 7.8 percent efficiency -- the most efficient reported to date, the researchers believe.
Consumers aren't embracing electric cars and trucks, partly due to the dearth of charging stations required to keep them moving. Even the conservation-minded are hesitant to go electric in some states because, studies show, if fossil fuels generate the electricity, the car is no greener than one powered with an efficient gasoline.
A South African startup is combining recycled plastic with solar power to give underprivileged school children a stylish schoolbag that also supplies them with light to study by.
The company has developed Repurpose Schoolbags to provide children with backpacks that double as a source of light for children in places where electricity is lacking. The bags include solar-powered lamps that can charge during daylight hours, as well as reflector patches that will help keep kids safe when walking along roads—which in some poorer regions of South Africa have no pedestrian sidewalks—to and from school.
The price of solar makes it a real option for the people of Kentucky.
I live in the working class neighborhood of Schnitzelburg in Louisville. In 2008, only one home in my neighborhood was powered by solar panels, owned by a dentist with a huge heart and a grave concern for the externalized costs of our collective fossil fuel addiction. Solar was expensive then.
