By combining green wall technology and solar panels, researchers have been able to generate renewable energy during both night and day.

Researchers from Cambridge University have developed what is being considered “the greenest bus shelter” by combining solar power and plant power.

The scope of this project is much more vast than simply powering a bus shelter. Researchers are looking at this development as a possible answer to affordable power generation solutions for developing countries.

“To address the world’s energy needs, we need a portfolio of many different technologies, and it’s even better if these technologies work in synergy,” said Dr. Paolo Bombelli of Cambridge University’s Department of Biochemistry.

The bus shelter has the potential to power itself during both night and day times by harvesting the natural electron by-product of photosynthesis and metabolic activity, thus creating electrical current.

Offshore wind farms in the United States have been met with a lot of resistance. While countries such as Europe have roughly 2,488 off shore wind turbines up and running, America has none.

Cape Wind – an initiative in offshore wind farms out of Massachusetts – has been attempting to establish their 130-turbine project for quite some time now, but have not been able to cut through the red tape.

While the outlook for the Cape Wind project appears to be grim, another initiative is rising in the ranks and is determined to get the United States on the offshore wind farm scoreboard.

In an effort to promote the use of alternative energy, the first solar-powered plane is well on its way to making its round-the-world tour.

After 13 year of invention and ingenuity, Swiss pilots Piccard and Andre Borschberg are beginning preparations to launch the tour in less than a week.

Casey Emilius, ECS’s Meetings Coordinator, spotted an article in Inhabitat on an amazing feat in student ingenuity out of Nigeria.

College student Segun Oyeyiola has transformed a Volkswagen Beetle into a wind- and solar- powered car with just $6,000. By using mostly scrap parts donated by friends and family, Oyeyiola was able to keep costs down and skyrocket the renewable efficiency of the car.

The car is fortified by a strong suspension system to hold the weight of the solar panel on the roof and the wind turbine under the hood – which takes advantage of the airflow produced by the car while it’s in motion.

If you haven’t embraced solar energy yet, it may be about time to do so. After all, it is cheaper than grid energy in 42 of the 50 largest cities in the United States.

According to the study “Going Solar in America: Ranking Solar’s Value in America’s Largest Cities,” a fully financed solar system costs less than residential grid energy purchased in over 80 percent of the largest U.S. cities. Additionally, 9.1 million single-family homeowners live in a place where their utility bill outpaces what solar would cost.

The falling cost of solar panels and solar fuel cells is largely driven by, in part, research into new materials and developments in the sciences. Check out a few interesting reads on solar energy from the ECS Digital Library:

• “Photobioelectrochemistry: Solar Energy Conversion and Biofuel Production with Photosynthetic Catalysts” (It’s open access!)
• “The Role of Energy Levels in Semiconductor-Electrolyte Solar Cells“
• “Photoelectrolysis and In Situ Storage of Solar Energy” (Throwback to 1989!)

Using a desktop computer, scientists can query the model about the thermodynamic properties needed to create the desired catalysts. They can use those parameters to inform experimentalists in their synthetic work.

We’re one step closer to transitioning renewable energy sources from intermittent to sustainable with this new development from Pacific Northwest National Laboratory.

Scientists are eliminating all of the unnecessary detours when dealing with molecular catalysts by elaborating on a strategy to map the catalytic route. With this strategy, researchers can modify just one part of a catalyst and see how that affects everything – including all the side reactions.

“We now know how catalysts with desired properties will behave in a given circumstance before we ever leave the computer. By working backwards, we can even ask which catalysts are the best performers for a set of conditions. We are on the verge of designing molecular electrocatalysts in silico — or conducting research by means of computer modeling,” said study co-leader, Dr. Simone Raugei.

Countries around the world have been embracing solar energy with open arms – just take a look at Germany or Switzerland. In the United States, however, solar energy has made its way into the mainstream, but has not gone as far as many environmentalists would like. With the advances in drilling technology in the U.S., one is left to wonder what the next big breakthrough in the nation’s energy supply will be.

The Wood Mackenzie consultant agency out of Scotland believes the next big thing in energy in the U.S. will be solar, and they’ve got some pretty solid reasons.

With climate change being a continually rising global dilemma, many scientist have turned their attention to research in the area of renewable energy sources. Even with some of the most brilliant minds working on improving efficiency and price of solar cells, they are still not widely used due to the high cost of materials used to develop the them. Now, a scientist may be on the path to cracking the code on material prices of solar cells by using nanotechnology.

Elijah Thimsen, assistant professor at the School of Engineering & Applied Science at Washington University in St. Louis, worked in conjunction with a team of engineers at the University of Minnesota to develop a technique to increase the performance of electrical conductivity.

Improvements in solar power are being developed all around the world, with scientist and researchers continuously attempting to apply electrochemistry and other sciences to solar cells in order to improve efficiency. Recently, the National Renewable Energy Laboratory (NREL) has reported one of the highest photovoltaic cell efficiencies achieved across all types of solar cells.

Researchers at the NREL have demonstrated a 45.7 percent conversion efficiency for a four-junction solar cell at 234 suns concentration.

The SparyLD system developed by University of Toronto researchers can spray colloidal quantum dots onto flexible surfaces.

Teams of scientists from around the world have been working on a way to produce spray-on solar cells for some time now. Recently, a team from the University of Toronto Faculty of Applied Science & Engineering has moved to the forefront of the race due to their latest breakthrough involving a new method for spraying solar cells onto flexible surfaces.

The prototype applies colloidal quantum dots via spray. These dots are a type of nanotechnology material that are light-sensitive.

This from Gizmag:

In such spray on solar cells, quantum dots would act as the absorbing photovoltaic material. Because they have a band gap that can be tuned by altering the size of their nanoparticles, they can be made to soak up different parts of the solar spectrum. This could prove particularly valuable if they were to be used in multi-junction solar cells, where dots small and large could sit alongside each other to widen the cells’ energy harvesting potential.
