US Army Claims Solar Cell Breakthrough

Written by , on July 8, 2015

U.S. Army researchers at the Redstone Arsenal have developed a new type of solar panel which they say is a significant breakthrough in solar energy production being much thinner, more efficient and cheaper than current panels.  Read more »

10 Years of Progress in Renewables

Written by , on June 19, 2015

In its 2015 “Global Status Report”, REN21, the global renewable energy policy network, has summarised the increase in renewable energy capacity in the 10 years from 2004 to 2014. In 2004, global renewable power capacity (excluding hydro) was 85 gigawatts. In 2014, it reached 657 gigawatts.  Read more »

Becoming “Water Neutral”

Written by , on March 11, 2014

A number of companies and other organisations around the world, including CocaCola and Sainsbury's, have announced that they are striving to achieve "water neutrality". But how can a company like Coca-Cola, whose business is selling water, be water neutral? The term "water neutral" seems to suggest that the company is seeking to have zero net […]  Read more »

Drones to Collect Solar and Wind Energy

Written by , on February 12, 2014

New Wave Energy, an English company, has plans to build a high altitude aerial power plant, consisting of networks of unmanned drones that can harvest solar and wind energy and transmit it wirelessly to receiving stations on the ground. As sunlight radiates down to the Earth's surface some of its energy is absorbed into the […]  Read more »

Using Steam Engine Technology for Power Storage

Written by , on November 30, 2013

A group of Australian engineers has formed a company, Terrajule, to develop a novel energy storage solution. The Terrajoule system combines concentrated solar thermal energy, steam engines and an integrated storage system using an insulated pressure vessel. The concentrated solar thermal energy is used to produce steam. Since it is impractical to store steam for […]  Read more »

Falling Particle Solar Thermal Power

Written by , on September 17, 2013

Engineers at Sandia National Laboratories in New Mexico, and partner institutions, are using a falling particle receiver to more efficiently convert the sun's energy to electricity in large-scale, concentrating solar power plants. The falling particle receiver developed at Sandia drops sand-like ceramic particles through a beam of concentrated sunlight and captures and stores the heated […]  Read more »

Solar – a $77 billion Industry

Written by , on August 21, 2013

Bollomberg has created this short video of facts about the state of the solar industry. It emphasises how global solar energy capacity has soared in the past 5 years yet Earth's most abundant energy source still provides only a fraction of our total energy.  Read more »
