Entech Solar energy hybrid has hopes for bright future

By - August 14, 2009 2 Pictures
Renewable energy technology company Entech Solar has completed a preliminary design review and prototype of its next-generation concentrating solar product, ThermaVolt II, which combines concentrating photovoltaic and thermal (CPVT) technology. The company says its product delivers four to five times the amount of energy compared to traditional photovoltaic systems and costs less to produce. Read More

Milan trade fair to commission world’s biggest rooftop solar power installation

By - August 10, 2009 4 Pictures
Bigger may not always be better but when it comes to solar power generation it's a plus. The rooftop photovoltaic power installation at the Milan trade fair will cover around 270,000 square meters (2.9 million square feet) and have a peak installed capacity of at least 18 megawatts (MW). This will put it ahead of the biggest existing rooftop solar plant at General Motors in Zaragoza in Spain, which has a peak capacity of 12MW. Read More

MotionPower energy system testing expanded

By - August 3, 2009
When we first came across MotionPower, a prototype system that converts the kinetic energy from cars driving over it into electricity, we mentioned we would keep tabs on the technology to see if it could make the leap to real world implementation. Well, the company behind the MotionPower system, New Energy Technologies, has taken the next step along that road by expanding the durability field tests of the device. Read More

Going Green: Monitoring energy consumption in the home

By - August 2, 2009 3 Pictures
Perhaps the first step on the road to being green comes from learning a bit more about the various appliances in the modern home and how much energy they actually use. There are a range of home energy meters available for just this purpose, reporting not only current usage in monetary terms, but also estimated CO2 emissions, power consumption and historical data that can be used to identify and cut down during periods of excessive consumption. So what are the options? Read More

Organic solar power efficiency gets a boost

By - July 30, 2009
Few would argue with the attractiveness of solar as an alternative energy source, but the cost of conventional photovoltaics has long been a stumbling block on the path to making it a viable option. This is changing rapidly. Grid parity, as the target for equaling coal burning production costs is called, has recently been claimed by solar manufacturers and research dedicated to improving solar systems continues on many fronts. Photovoltaics using organic molecules is one of them. This technology promises cells that are cheap, easy to make and flexible, and this flexibility makes them suitable for a diverse range of applications like powering your mobile phone, or lining your backpack or window shades. The problem is that currently they only last a few thousand hours and are inefficient, converting less than 6 percent of light into electricity. Work by researchers at the National Institute of Standards and Technology (NIST) could help change this. Read More

Vertical Landscapes: The only way is up for green cities

By - July 28, 2009 7 Pictures
Demand for office and housing space in ever diminishing land space has led to taller and taller buildings reaching for the skies in cities around the world. This shortage of land in many cities has unfortunately also led to a scarcity of natural vegetation in urban settings. We’ve looked at several vertical-farming concepts - dedicated buildings that provide space to grow crops in city centers - but a new architectural system from Vertical Landscapes (VL) seeks to invite nature back into our cities on a broader scale. The architectural system transforms buildings into columns of vegetation to add a much needed touch of green, help clean the city air and possibly even produce small scale crops, all while retaining the building’s usual use for office or housing space.

Biodiesel goes to the birds

By - July 23, 2009
Scientists in Nevada have found a new and environmentally friendly source of biodiesel – “chicken feather meal”, a delightful material that consists of chicken feathers, blood, and innards made from the 11 billion pounds of poultry industry waste that accumulates annually in the US alone. Read More

Texas to benefit from largest offshore wind concessions in the USA

By - July 23, 2009
The push for more dedicated use of renewable energies has been given a boost recently by Texas startup Baryonyx Corp, which has successfully procured the lease for what will be the largest offshore wind concessions in the USA. A total of 8,000 acres of land in Dallam County and 38,000 acres in the Gulf of Mexico will power ‘Tier4’ data centers by generating a potential 3GW of energy. Read More
