London's South Bank Tower to generate electricity from solar rooftop system
http://www.edie.net/news/10/London-s-South-Bank-Tower-to-generate-electricity-from-solar-rooftop-system/
London's South Bank Tower is expected to save around 11,850 kg of C02 after a 100-panel, 26 kilowatt-peak (kWp) solar PV system was installed on the roof of the newly-developed skyscraper. - edie news centre

Over the course of a 10-hour flight, a passenger airliner burns roughly 36,000 gallons of fuel – about one gallon every second. That’s why cleaner alternative sources of jet fuel are a priority for the airline industry and the +U.S. Department of Energy. Now, PNNL researchers and industry partners have reached a milestone. They converted alcohols derived from captured carbon monoxide, a byproduct in the production of steel, into synthetic paraffinic kerosene, a non-fossil-based jet fuel.

MIT scientists claim their new thermophotovoltaic (STPV) device more than doubles the theoretical limit of efficiency, "potentially making it possible to deliver twice as much power from a given area of panels". However the materials they used, nanophotonic crystals, are not ready for mass production yet.

Under Pressure:
New technique could make large, flexible solar panels more feasible
A new, high-pressure technique may allow the production of huge sheets of thin-film silicon semiconductors at low temperatures in simple reactors at a fraction of the size and cost of current technology

Solar Powered Farms
On this episode we're taking a look at using solar energy on farms. We're visiting two farms in Rockingham County, a dairy farm and a poultry farm to see how they are harnessing the power of solar. All on this addition of Virginia Farming!

Why solar thermal energy systems may be the planet's lifejacket

What is our energy needs?
All over the world, energy efficiency requirements has turned the actual energy consumption to less needs for electricity. This is because all manufacturers of light bulbs, PC's, TV's, freezers, refrigerators, ovens and other appliances has successfully been certified with energy labels that tells the users how much energy they may save by selecting the right equipment. Consequently, our need for energy that drivers these apparatuses is decreasing rapidly.
That is not the case for heating, cooling and hot water demands. While new apparatuses is considered a status and a better lifestyle, so is the trend towards more fancy bathrooms with tropic showers and bigger bathtubs and our seeking for better and more comfortable homes with generally higher indoors temperature during the cold season and generally colder temperature during the warm season. All of which increases our heating and cooling demands dramatically.

What is solar thermal?
Solar thermal energy is a conversion of the solar energy in the Ultraviolet , Visible and near Infrared spectrum of the solar energy. Some of the technologies present on the market already, may utilize as much as 90% of the Sun's constant irradiation at the Earth's surface. This means that between 1,000 and 200 Watt's are converted into heat depending on your location and time of the year. Solar cells, on the other hand, only harvest in the visible spectrum and this is why:

1) The energy efficiency is up to 90% for solar thermal opposed to ≈ 15% for solar cells.

2) Cost of solar thermal is 0.05 € per kWh opposed to solar cells at 0.22 € per kWh. In imperial units 204 USD per BTU for solar thermal opposed to 853 USD per BTU for solar cells

3) The CO2-emission for solar thermal is at 3 grams per kWh opposed to 28 grams for solar cells. In imperial units 22 lb per BTU for solar thermal opposed to 210 lb per BTU for solar cells.

The benefits of solar thermal
Solar thermal energy is locally produced hot water that can be used to heat up your building and hot water supply or as cooling of buildings.
You will usually have your money back within 4 years and the installations will last for more than 30 years.

-No grid needed
-Minimized CO2-footprint
-Easy installation
-Low or no maintenance
-No more heavy energy bills

Hybrid batteries that charge faster than conventional ones could have significantly better electrical capacity and long-term stability when prepared with ion soft-landing. This high-precision technique resulted in electrodes that could store a third more energy with twice the lifespan compared to those prepared by a conventional method. This method could eventually lead to cheaper, more powerful, longer-lasting rechargeable batteries. Read more at http://goo.gl/V43VwG.

A "cleaner" grid, with a high percentage of wind and solar, may come sooner than expected, thanks e.g. to new energy storage technologies (and technologies becoming cheaper,) but also thanks to improved ways of managing power demand.
Renewable energy may be more robust than it's been getting credit for.

Talking about green energy, solar power in commercial buildings is a much discussed and debated subject these days. Off-Grid system or rooftop solar panel installation in various commercial building can definitely serve the purpose of growing demand of electricity.

GE developed a process to store excess energy using CO2, along with a small scale turbine to later release most of that energy into the grid. Alternatively the same turbine could be used to tap energy from gas plants that otherwise would be wasted, according to General Electrics.
Carbon captured by coal plants would drive turbines that deliver power at night.

More space to soak up the sun
Hundred-metre long platforms which remain steady and stable in rough sea weather: TU Wien’s lightweight construction creates new space for solar energy out on the water.
This new construction allows areas the size of football fields to be made available on the water with ease. The research team at TU Wien has developed concepts for harnessing the sun over the water using photovoltaics and parabolically shaped mirrored troughs, with many
