Electricity generating windows: An interview with John Conklin of SolarWindow Technologies

SolarWindow is a new see-­through electricity generating coating technology designed for glass windows for tall towers, skyscrapers and detached homes in the US.  The company claims the product has the potential to offset 30 to 50 percent of the energy demand when installed on a 50-­story building - with a calculated one­-year financial payback.

SolarWindow has been developed to performance standards in order to give real estate developers, engineers, architects, building designers, and future customers plenty of financial incentive and it has been rigorously tested for durability, degradation, and performance.

REM talked to SolarWindow President and CEO John Conklin to find out more.

Wireless energy transfer strips for electric vehicles and buses  

Alongside innovative battery technology, another potential method for charging electric vehicles (EVs) could be wireless energy transfer strips installed on road surfaces. The potential for new electric vehicles is quite exciting, particularly with regard to mass transit vehicles such as buses and trams, but the technology could one day be used for EVs also.

Clean mass transit in Uganda – Buses powered by renewable energy         

All around the world, the green vehicle revolution is starting to speed up. At first, the main impetus focused on electric vehicles (EVs) and other green cars powered by hydrogen or running as hybrids. However, increasingly, clean vehicle technology is beginning to appear in mass transit vehicles, particularly buses.

What is driving the falling cost of solar energy?

Can new window designs help buildings to generate their own energy?

 Modern buildings currently account for about 40 percent of the energy consumed in developed countries, of which two-thirds can be attributed to heating and cooling. However, over the years, a number of innovative window designs have appeared as part of overall attempts by the energy sector and research institutions to cut energy use and reduce costs.

Can wind and solar power displace coal? Yes, it can – easily

 Despite all the success with renewable energy happening all over the world, some people still like to question that success based on flawed information.

The potential of graphene for renewable energy systems

Earlier this year, in late January, Manchester and Abu Dhabi Universities announced their intention to collaborate on a project to produce foam containing graphene, a material consisting of a single layer of carbon atoms arranged in a honeycomb lattice which is 10 times stronger than steel but 1000 times lighter than a sheet of paper per unit area.

UK could deliver a world-leading renewable energy system says Scottish Renewables

A new paper from industry body Scottish Renewables has found that UK government spending could deliver a world-leading renewable energy system if £500 million of allocated funds are targeted correctly.

Tracking the sun: trackers for solar power systems

A solar tracker is a device that orientates a PV system, particularly a large installation such as a solar farm, towards the sun in order to enable it to capture more solar energy than it would otherwise do without such a device. In essence, tracking is about minimising the angle of incidence between incoming sunlight and a solar panel array. Solar panels can capture the diffuse part of the sun’s light, in the blue sky which also increases proportionately when it’s cloudy, as well as direct sunlight and solar trackers can increase the amount of solar energy captured. In general, tracking systems can usually capture an additional 50 percent of sunlight in summer and 20 percent in the winter, but this differs according to latitude.

Europe’s largest floating solar farm currently being installed in London

Europe’s biggest ever floating solar panel array is being installed on London’s Queen Elizabeth II reservoir as part of Thames Water’s ambitious bid to self-generate a third of its own energy by 2020.

Which is better – Net Metering or Feed-in Tariffs?

Net metering was first established in the US state of Idaho in 1980 and in Arizona in 1981, although Minnesota is commonly acknowledged as the first state to pass an actual net metering law in 1983. It is now commonplace in certain countries, particularly the USA, but how does net metering fare against Feed-in Tariffs (FiTS) with regard to its effectiveness as an incentive for renewable energy installation? Closer scrutiny of the two approaches provides an easy answer – FiTS wins easily, being far more effective as a means of incentivizing and promoting renewable energy development.

Distributed generation threatening utilities? How can they respond?

Last year, NV Energy, a utility covering the US state of Nevada, found itself embroiled in a confrontation with its solar energy customers over fees distributed energy generation (more simply ‘Distributed Generation’ or DG). In January this year, the company offered them a compromise. The company, which is owned by Warren Buffett’s Berkshire Hathaway Energy, has announced it will submit a proposal to the state regulator that will allow customers who already own solar panels to avoid new fees over the next 20 years. These fees became effective earlier this year and are highly controversial. They would still be levied against new solar energy customers. Nevada Governor Brian Sandoval argued that people who don’t own solar panels are paying more than they should for grid maintenance and interconnections while solar panel owners enjoy the benefits. NV Energy and the PUC take the same view.

This is just one episode in an ongoing struggle in which utilities all over the world have been trying to cope with the growing popularity of distributed generation technologies, often based on renewable energy such as solar power, which is enabling more and more people to generate their own power rather than relying on supplies from utilities.

California ‘gets it’ – The Golden State’s pro-active stance on climate change

Most people in the world actively engaged in watching the news know about the California drought, which has impacted the state particularly badly, hitting its agriculture and causing the largest spate of wildfires in their history. In April 2015, the conditions causing the drought also broke California’s low snowpack record which, according to the state’s Chief of Snow Surveys, Frank Gehrke, was ‘obliterated’, shrinking to just 3 percent of its normal size.

Wind Turbine Noise – Fact or Fiction?

Over recent years, the wind industry all over the world has had to endure a spate of protest against the construction of onshore (and offshore) wind farms. At first, the complaints were concerned with visual impact, but more recently wind turbine noise has also been a major source of complaints. Collectively, this level of opposition has been enough, in many cases, to completely thwart the development of wind farms in certain areas.

However, is there really any evidence to suggest noise, if indeed wind turbines produce any of any real significance, is a major problem? Survey after scientific survey on the matter has rejected the suggestion after prolonged and careful analysis.

Evaluating the Earthship – an effective sustainable building concept, or not?

Earthships are green buildings constructed using a variety of recycled materials and which also use natural processes, such as solar energy, rainwater and plants, for the various utilities such as heating, power and water. The concept has worked well in warmer regions such as New Mexico where it was originally developed, but is it really suited to colder climates such as Northern Europe?
