London Mayor Boris Johnson has revealed City Hall is seriously considering trialling new technology that allows roads to convert solar rays into electricity.
Speaking at Mayor's Question Time this week, Johnson said he believed there was "much more scope for generating solar power in London than we previously thought" and that his environment department has been studying solar road technology "with interest".
Batteries paired with solar panels aren’t just intriguing customers in the U.S., Europe and Japan looking to ditch their utilities. People are slowly adopting batteries and solar panels in offgrid markets, too, using their cell phones to make reoccurring micropayments and using solar energy to replace kerosene lanterns.
This week startup Fenix International — which is based in San Francisco and Kampala, Uganda, and was founded in 2009 — announced that it has raised a Series B round of $12.6 million to get its battery and solar panel product into the hands of more customers. Fenix emerged from stealth in late 2010 with a plan to sell its lead acid battery product, which comes with a solar panel and other energy adapters, to customers in rural Africa.

"Nous avons cherché plusieurs moyens de rendre les panneaux solaires plus efficaces à des coûts plus bas" a déclaré Michael McGehee, co-auteur, et professeur des sciences des matériaux et de l'ingénierie à Stanford.
For a relatively new and untested renewable-energy market, Chile has a remarkable number of strengths. The country has incredibly attractive solar resources, according to Joel Link, vice president of development and global head of mining development for SolarReserve. “The Atacama Desert, in northern Chile, has arguably the world’s strongest solar resource,” he says, noting that this area also happens to be home to the lion’s share of the country’s mining activities.
In addition, parts of the country are extremely appealing to wind farm developers.
Flaws found in some Chinese solar panels can drastically eat into their efficiency, reducing how much power the panels will produce as the country races to meet aggressive goals to hold the line on fossil fuel emissions.
The defects, found in products set to be used only in China, are in a coating that suppresses reflections on glass, allowing the panels to capture more light. About 23 percent of samples taken from dozens of Chinese companies failed to meet requirements, according to regulators in China. For samples from Jiangsu, the eastern province where much of the glass is made, the rate was as high as 40 percent.
The World Future Energy Summit (WFES) is the Middle East’s largest gathering on future energy and one that drives actionable solutions to the world’s energy challenges.

Held under the patronage of His Highness Sheikh Mohammed Bin Zayed Al Nahyan, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the UAE Armed Forces, WFES will catalyze partnerships through the Project and Finance Village, TechTalk, and the Sustainability Business Connect Program, where leading companies representing the entire energy spectrum – from hyrocarbons to renewables – will gather to showcase innovations and share best practices.
The solar industry added jobs at a rate nearly 20 times faster than the national average last year, according to an annual report.
The report, published Thursday by the Solar Foundation, found that more than 31,000 solar jobs were added in the U.S. between November 2013 and November 2014. According to the report, 85 percent of those jobs were new, rather than jobs that already existed but which added additional solar responsibilities.
“The Atacama Desert, in northern Chile, has arguably the world’s strongest solar resource,” he says, noting that this area also happens to be home to the lion’s share of the country’s mining activities.
In addition, parts of the country are extremely appealing to wind farm developers. Dominic Duffy, chief operating officer for Mandalay Resources Corp., which runs the Cerro Bayo silver and gold mine in Patagonia, says that in this part of Chile, “the choice is very easy. The wind never stops, and it’s a very strong wind.”
Duffy points out that Chilean mines face a clear challenge: The country is running short on energy.
EDF Energies Nouvelles a annoncé la mise en service de la centrale photovoltaïque de Toucan (5 MWc), en Guyane, qui a la particularité d'être dotée d'un dispositif de stockage de l'énergie et être équipée d'un système innovant de pilotage de ses équipements électriques, l'une des premières de ce type en France et dans le monde.
Située sur la commune de Montsinéry-Tonnégrande sur le littoral guyanais, la centrale solaire de Toucan représente une puissance installée de 5 MWc.
As we continue installing thousands of rooftop solar power systems on homes across the United States, we continue to gain a deeper understanding of what motivates people to pull the trigger and go solar.
While the decreasing cost of solar is the all-important driver, the incentive to install a solar array at home comes from a wide variety of needs and desires. These motivations are closely related to generational trends.
We’ve identified two pillars of current and future customers: The baby boomers, which we call the Bill Walton generation (after our spokesman and legendary basketball hall of famer) and the millennials, which we call the Netflix generation.
A new world record is making the future of solar energy look pretty bright. Researchers in Australia recently developed a solar energy system that can convert more than 40 percent of the sunlight that hits it into electricity the highest efficiency ever reported for a commercially available photovoltaic system.
The technology first achieved the record-breaking efficiency in outdoor tests in Sydney, Australia, and later at an outdoor test facility operated by the National Renewable Energy Laboratory (NREL) in Golden, Colorado, the primary lab for renewable energy and energy efficiency research in the United States.
LONDON (Thomson Reuters Foundation) - A new generation of solar panels made from a mineral called perovskite has the potential to convert solar energy into household electricity more cheaply than ever before, according to a study from Briain's Exeter University.
Super-thin, custom-colored panels attached to a building's windows may become a "holy grail" for India and African countries, Senthilarasu Sundaram, one of the authors of the study, told the Thomson Reuters Foundation.
If Saudi Arabia and solar power don’t look quite right together, it’s time to shake off that 1970’s oil crisis dust and take a look at the country’s recent forays into renewable energy. The latest move is a solar powered desalination plant aimed at treating 60,000 square meters of seawater daily for the northeastern city of Al Khafji. According to the developer, this will be the world’s first utility scale, solar powered desalination plant.
Zurich, Switzerland, January 20, 2015 – ABB, the leading power and automation technology company, is proud to accompany Solar Impulse and its crew on the plane’s flight around the world powered only by energy from the sun. Solar Impulse, based in Switzerland, announced today it will begin its historic flight between late February and early March in Abu Dhabi. In 2014, ABB and Solar Impulse formed an innovation and technology alliance to advance a shared vision of reducing resource consumption and increasing the use of renewable energy. “Solar Impulse will inspire a new generation to embrace innovation and technology to solve the planet’s biggest challenges,” said ABB Chief Executive Officer Ulrich Spiesshofer. “ABB will be with the Solar Impulse team every mile of its journey.”
After the Solar Impulse prototype’s 8 world records, when it became the first solar airplane ever to fly through the night, between two continents, and across the United States, it is time for Bertrand Piccard and André Borschberg to move on to the final phase of the adventure: the 2015 round-the-world flight.
A great historic first: for such an adventure, as for any premiere, there are no references. We were, and will be, faced with a number of challenges, leading us to push the limits of technological, human and piloting performance.
If clean energy is the future, then “cutting the cord” to your local power plant might be the next big step in the energy market. - Reuben Brewer - Energy
There's something going on in Kwigillingok, Alaska--a town with just 350 residents--that could change your life. Kwigillingok is off the power grid because it is too remote to be on one and generates its own power, which now includes electricity from wind turbines. This is the epitome of a microgrid, or a small closed power system that can operate independently, or in conjunction with, the larger power grid. Such small systems could be the future of power.
Ethiopia is aiming to enhance access to affordable and environmentally-friendly renewable energy for its population, with the country’s Ministry of Water, Irrigation and Energy announcing last month that it had signed an agreement with an Israeli solar-hybrid power company to further this goal. The leading Israeli developer of solar-biogas hybrid power technology, AORA, will be the first to provide solar-biogas hybrid power solutions for rural communities in Ethiopia.
Exosun, expert français dans la technologie des trackers solaires à destination des grandes centrales photovoltaïques au sol, a annoncé mardi dernier la signature de quatre contrats de fourniture de ces systèmes innovants avec trois acteurs de référence dans les énergies renouvelables en France.
Les quatre centrales solaires, productrices d'énergies propres, permettront de réhabiliter des friches industrielles. En effet, deux d'entre elles seront installées sur des sites de stockage de déchets, la troisième sur une ancienne gravière, et la quatrième prendra place sur un site industriel laissé à l'abandon. Avec une puissance totale installée de 20 MW, l'ensemble des sites produira 28 300 MWh/an, l'équivalent de la consommation électrique de près de 10 000 foyers.
Net zero energy building is the present and future of green building design. A lot of buildings, across the world are designed, so that they generate as much energy as they use – i.e. they are designed, based on the concept of NZEB. Ensuring prudent use of energy and maximum utilization of renewable and abundantly available energy sources is the key. However, now the world is ready to get its first net zero energy skyscraper.
