You don’t have to be a genius to realize that electricity will be the currency of the future. Also, unless something truly catastrophic happens, we can always rely on the sun to provide plenty of energy just waiting to be transformed into that much-needed electric current. Let’s just assume Elon Musk isn’t reading this and imagine that electric cars won’t catch on eventually. Will that be such a terrible blow for those in the business of creating electric power? Considering how everything else around you requires being plugged in at least once in a while to work, it’s safe to say that no, it won’t be.
An energy revolution could be driven by an extended tax subsidy that recently passed Congress.
There are side effects from the ITC extension that many in the energy industry don't fully appreciate. Solar will grow so much in the next five years that it will become a significant percentage of the grid, particularly in the Southwestern U.S., and as that happens it'll drive a whole new world of energy innovation that could change how we look at energy forever.
Solar powered drones offer a sustainable way to provide goods and services to remote areas quickly and effectively.
With technology leaping forward every day, many companies are seeking new ways to provide efficient, sustainable, and effective solutions. Their answer? Solar powered drones. As drone technology has improved, their accessibility has increased dramatically as well.
Solar power is changing the world, and it’s happening faster than you think.
Naysayers will say that solar power is still barely a blip — accounting for just one percent of global electricity supply. They’ll insist that the world will never rely on a power source that doesn’t work when it’s cloudy.
As solar tech advances, so too does how we store that energy for later use (like when it’s cloudy). Together, batteries and solar panels are going to send fossil fuels back to the land of the dinosaurs.
In late 2015, Uruguay announced that it was producing 94.5 percent of its energy from renewable sources, including solar. Amazingly, Costa Rica has delivered even more impressive numbers. As is the case with Uruguay, Brazil and Paraguay source most of their electricity needs from renewables, which is mostly hydroelectric power. Yet, especially in the case of Uruguay, these Latin American countries are increasingly investing in other renewable energy sources such as solar, wind and biomass. In terms of solar, Chile is king. Already a leader in the use of solar photovoltaics (PV), the country has upped its stakes in the renewable energy game in a big way with the construction of a 200-meter-tall solar tower. Atacama 1 expected to generate an impressive 110 megawatts — 24 hours a day, seven days a week.
EPFL scientists have developed a solar-panel material that can cut down on photovoltaic costs while achieving competitive power-conversion efficiency of 20.2%.
Some of the most promising solar cells today use light-harvesting films made from perovskites - a group of materials that share a characteristic molecular structure. However, perovskite-based solar cells use expensive "hole-transporting" materials, whose function is to move the positive charges that are generated when light hits the perovskite film. Publishing in Nature Energy, EPFL scientists have now engineered a considerably cheaper hole-transporting material that costs only a fifth of existing ones while keeping the efficiency of the solar cell above 20%.
It was the type of question that illustrates the fever that is gripping this small and specialist market, much as the hype that drove rare earth elements through the roof a few years ago and briefly allowed a flood of investment to be available for the development of new mines and processing operations such as Molycorp’s Mountain Pass, only for the market to then collapse again a year or two later.
Marianne Fairbanks took a look around the UW-Madison studio where she teaches weaving — a classroom filled with large, wooden floor looms that some might describe as “quaint” — and came up with another idea.
She bought a used floor loom herself, then commissioned an artist to paint it in a “futuristic” style.
“So that it’s not so grounded in the past,” she explained.
Early in the Paris climate talks last month, Todd Stern, the US special envoy for climate change, set out for a group of reporters the administration’s view on how the problem should be tackled. “We have a lot of technology that is available right
Establishing a secure financial future for your retirement requires that you explore a variety of options, but most homeowners don’t realize that installing a solar panel system can be one of the smartest retirement investment options available.
Recently, Google started the Sunroof project, a service that calculates potential energy savings of home owners due to solar facilities on their roofs. However, this project covers a few cities in the USA only. Scientists ...
The building sector is accountable for about 40% of energy use, while healthcare centers account to a 6% of the total energy consumption in the public building sector. The envelope components are not much different from the conventional buildings, but healthcare facilities have several industry specific energy consuming systems that require attention.
It has been a source of enormous pleasure for me during the past five years to see the solar power skeptics proven wrong. Back in 2010, I almost never saw articles about solar’s potential to replace fossil fuels as our primary energy source. Then, in early 2011, futurist Ramez Naam posted one of the most important articles in recent history. The post, titled Smaller, cheaper, faster: Does Moore’s law apply to solar cells? , demonstrated how solar power prices had been declining exponentially at a steady clip for decades.
Solar sector needs better power storage, grid infrastructure and government support to meet bullish growth predictions.
Sixty years ago, the price of solar panels was astronomical. At a cost of $1,910 (£1,350) per watt in today’s money, the only practical use for them was in space on the US Vanguard 1 satellite, which launched in 1958.
But slowly and then precipitously the price of building a solar cell came down. Today it is less than $0.80 (£0.55) per watt. The subsequent proliferation of panels (especially in Europe, China, US and India) has tracked along the dizzying curve that eventually lead to the market domination of the car, the mobile phone and electricity itself.
Ségolène Royal a annoncé que d'ici cinq ans la France devrait compter 1000 kilomètres de routes solaires. Dans les prochaines années, le réseau routier devrait se couvrir de panneaux photovoltaïques.
Et si les routes devenaient de vastes panneaux solaires? C'est le souhait de Ségolène Royal. Lors de ses voeux mercredi au Groupement des autorités responsables de transport, une association regroupant de nombreuses collectivités territoriales, la ministre de l'Écologie a annoncé "1000 kilomètres de routes (...) couvertes de panneaux solaires" d'ici cinq ans.
For homeowners considering solar power, a major concern is whether energy is still produced when conditions are less than ideal. After all, the Intermountain region of the U.S. is known for weather extremes. Snow, rain, sleet and clouds can all occur, sometimes all within a few hours on a given day.
Solar panels are designed to withstand the worst possible weather while still producing sufficient power.
A common criticism of a total transition to wind, water and solar power is that the US electrical grid can't affordably store enough standby electricity to keep the system stable. Now a researcher proposes an underground solution to that problem.
A new study shows that wind, water and solar generators can theoretically result in a reliable, affordable national grid when the generators are combined with inexpensive storage.
Learn how breakthroughs in clean technology can take us to new heights with the explorers who are set to break the record for the world’s longest solo flight using only solar energy. André Borschberg and Bertrand Piccard took off from Abu Dhabi in March and aim to complete the circumnavigation of the Earth by returning to the UAE. Watch them speak live at the World Economic Forum in Davos at 12.45pm.
A new paradigm for the development of photo-bioelectrochemical cells has been reported in the journal Nature Energy by researchers from The Hebrew University of Jerusalem, in Israel, and the University of Bochum, in Germany.
The design of photo-bioelectrochemical cells based on native photosynthetic reaction is attracting substantial recent interest as a means for the conversion of solar light energy into electrical power.
Célèbre pour son projet de tour du monde en avion solaire, la société Solar Impulse s'intéresse maintenant aux drones solaires. Un prototype doit émerger dans les prochaines années.
Les drones solaires ont le vent en poupe dans la Silicon Valley. Avec Aquila, Facebook est en train de plancher sur un prototype d’appareil capable de se maintenir à très haute altitude pendant plusieurs mois. De son côté, Google est aussi sur le coup. Le groupe a mis la main sur la société Titan Aeorospace au printemps 2014. Celle-ci se consacre aux aéronefs sans pilote ayant une très longue endurance.
First, free education, and now solar energy. Chile is fast becoming a people- and environment-friendly nation.
Solar power isn't new, but Chile has proven that Latin America can still join the conservation revolution. This is a lofty triumph for the country that also became king in another solar initiative -- solar photovoltaics (PV) use.
For solar energy, the South American nation is investing big time on Atacama 1, a 200-meter-tall solar tower under construction and will soon become a source of renewable energy.
Au cours des dernières années, des discussions complexes à propos de l'exposition géographique des cellules solaires - sud ou ouest - a probablement laissé certains clients perplexes quant à la meilleure façon d'orienter leurs panneaux.
Les chercheurs tentent désormais de résoudre ce problème en développant des cellules solaires capables de capturer la lumière à partir de presque n'importe quel angle, avec en bonus, des panneaux auto-nettoyants. Leur rapport figure dans la revue ACS Nano.
Clean energy was one of the important issues in the Paris Climate Agreement, which various nations signed. Fuel cells produce clean energy from a chemical reaction between anodes and cathodes. In contrast, solar energy produces energy from sunlight. After this historic agreement, industries might change their focus. Different nations will try to enhance their exposure to the technology. As the scenario changes, companies operating in this sector may be lucrative for investors.
The demand for photovoltaic (PV) systems has increased over the past few years all over the world. Future growth markets outside the temperate zones in particular, for example desert, (sub)tropical or alpine regions, also intend to use solar to a greater extent for generating electricity. However, there is currently only one standardised PV system for all climate zones. No options are available that can be adapted to different climate or grid conditions in specific applications.
