The Solar I concentrating solar plant will have 3,500  parabolic mirrors trapping the sun'...

The race to build the world’s largest solar power plant continues with Arizona Public Service and Starwood Energy Group Global LLC unveiling plans for a 290-megawatt concentrating solar plant in the Harquahala Valley, 75 miles west of Phoenix. As one of the largest solar plants in the world Starwood Solar I will produce enough electricity to power more than 73,000 homes and is scheduled for completion by 2013.  Read More

The solar bullet train could make the 116 mile journey from Tucson to Phoenix in just 30 m...

Bullet trains are considered by many to be one of the greener forms of transport, so imagine how environmentally friendly they might be if the sun’s power was harnessed to power them. That’s precisely what Solar Bullet LLC hopes to do with its 220mph solar bullet train, which the company claims can travel from Tucson to Phoenix in just 30 minutes.  Read More

The Powerbrella does the work of two: it provides shade and solar-generated power

A retractable alfresco umbrella that converts sunlight into electricity to charge laptops, mobile phones, iPods or any other portable device that might be used relaxing or working outdoors is in development following a partnership between Skyshades, a supplier of shade structures, and Konarka Technologies, the developer of Power Plastic.  Read More

The “roulette wheels” created by MIT researchers to show the range of probability of poten...

Research carried out by the MIT's Center for Global Change Science has predicted that global warming will be roughly double previous estimates – and could be even worse than that. While a major 2003 study indicated a median projected increase in earth surface warming of 2.4 degrees Celsius, the new study, which takes into account possible changes in human activities, points to a median probability of surface warming of 5.2 degrees Celsius by 2100 unless drastic action is taken.  Read More

The simplified process converting biomass to HMF

Biofuels continue to steal the spotlight when it comes to the search for a renewable, environmentally friendly replacement for crude oil. While that’s understandable when considering the transport industry, but crude oil is also used in the production of conventional plastics and chemical products such as fertilizers and solvents. Now chemists have learned how to convert plant biomass directly into a chemical building block that can not only be used to produce fuel, but also plastics, polyester and industrial chemicals cheaply and efficiently.  Read More

The electric Tesla Roadster comes out on top of the ethanol powered Saab 9-5 in the miles ...

Running vehicles on biofuels such as ethanol reduces CO2 emissions and offers a way to lessen the world's reliance on oil. While this sounds great from an environmental perspective, the energy required to produce the biofuel and the land clearing for crops that can result means biofuels aren’t necessarily the environmentally friendly solution they initially appear to be. Recognizing this, researchers have analyzed the best way to maximize the “miles per acre” from biomass and discovered that the far more efficient option is to convert the biomass to electricity, rather than ethanol. Another tick for the electric car.  Read More

Etive kinetic energy charger harnesses your energy to create a power source for recharging...

Hiking has its share of highs and lows. One of the less pleasing aspects is ensuring you have an adequate source of energy to power your personal electronic equipment. There are a number of renewable energy options available that you may consider when planning your next hiking trip. You could harness the sun’s energy and use a solar-powered charger or solar-wrapped batteries. Perhaps you might choose to use wind power to keep you in touch with the world? But wouldn’t it be great if you could harness power using your own kinetic energy? It makes sense. You’re using your legs all day, surely all that sweat, pain and muscle fatigue is good for something? Enter the Etive – a concept device that uses kinetic energy as a power source for recharging all the electronic gadgets you bring to the great outdoors.  Read More

Minneapolis-St. Paul International Airport (MSP) has recently installed 10 wind-powered el...

Airports are windy places and it seems logical to harness this power to reduce operating costs and boost green credentials. In line with this, the environmentally minded Metropolitan Airports Commission (MAC) at Minneapolis-St. Paul International Airport (MSP) has recently installed 10 wind-powered electricity generators and purchased an electric-powered utility vehicle for use at the airport.  Read More

Purdue University doctoral student Jonathan White holds a cross-section of a wind turbine ...

Clean, renewable energy is freely available – in the form of wind, sun and water. However, harnessing it reliably and cost-effectively remains a barrier. Wind power is one of the fastest growing alternative energy markets and researchers at Purdue University and Sandia National Laboratories in West Lafayette, Indiana, are working to make wind turbines more efficient, reliable and resilient.  Read More

About a billion tires are discarded around the world each year despite demand exceeding su...

A new method of recycling old tires to produce high-quality rubber powders for making new rubber products is being developed in Australia. Its developers say it is energy-efficient, economically viable and environmentally responsible, and they hope it will result in 50 per cent more tires being recycled.  Read More
