While the use of solar cells is become increasingly widespread, the silicon technology used in many types is becoming obsolete. JP Casey looks at concentrated solar power, micro-trackers and perovskite compounds as innovations that could potentially improve solar efficiency.

#Retrofit-lamps# LED T5 Tube is a kind of innovative and energy-saving product that replaces the traditional one, which is assembled with standard T5 pins with higher efficiency. 25Watts, beam angle: 130 degree. (FOB unit price: US$18.02) Learn more http://www.renesola.com/w_detail/882

The proliferation of portable consumer electronics such as computers, cell phones and e-book readers combined with expected expanded production of hybrid and all-electric vehicles has placed significant new demands upon manufacturers for low-cost, energy efficient and environmentally-friendly batteries.

The bus is fitted with an electric-motor hybrid system powered by batteries and fuel cells, and is fueled with high-pressure hydrogen gas. During operation, the vehicle does not emit carbon dioxide, said to be a cause of global warming, or any other atmospheric pollutant such as nitrogen oxide; it is both highly energy-efficient and very quiet.

The latest trends in clean tech. From renewable energy sources, to less toxic electronics and more efficient information technology,

Growing Dome® Greenhouses, tried and tested in the Rocky Mountains, allow you to grow fresh vegetables, flowers, fruit and herbs year round, with minimal extra heating or cooling.

Small, high efficiency wind turbines from scotland

GreenWorld Development, a Florida based company that develops sustainable products for efficiency goods and services, has signed a Memorandum of Understanding (MOU) to buy 51% stake in the UK waste recycling company FE4.

The size, shape and organization of light-harvesting complexes such as chlorosomes are critical factors in electron transfer to semiconductor electrodes in solar devices. Understanding how chlorosomes function in nature could help scientists mimic the chlorosome's efficiency to create robust biohybrid or bio-inspired solar cells.

Waste2ES is a comprehensive solution that enables commercial kitchens to optimise their operations and maximise their returns on investment, while also minimising waste and reducing their environmental footprint. By implementing sustainable practices and technologies, such as food waste reduction, energy-efficient equipment, and water conservation measures, Waste2ES helps commercial kitchens reduce their environmental impact and contribute to a more sustainable future.

A South Korean university has come one step closer to developing wireless power by improving both efficiency and transmission distance, a breakthorugh which its developers believe could lead to wireless energy becoming as popular as WiFi in the not to distant future.

There was a time when a laptop could weigh 10 pounds and still sell-a time when a cell phone was larger than a pocket-and a time when an iPod only played music.

Labelled as the largest, cleanest and most efficient coal-fired power station in the UK, the 4,000MW Drax plant supplies around 7% of the UK's electricity needs.

Gas turbine design has changed to account for the growing use of combined heat and power (CHP) plants.

Lexus Selects Visible Light Solar Technologies' Solar/LED Lighting Solutions for New Mexico Dealerships, Gaining Over 80% Efficiencies

Green is the most efficient "semi-transparent" colour for producing electricity, although red and purple also work well. Oxford PV predicts that manufacturing costs of its product will be around 50% less than the current lowest-cost thin film technology and expects its new mechanism will eventually match the unsubsidised cost of electricity generated from fossil fuels.

By making solar panels that are lighter, more flexible, partially transparent and organic, a team of researchers hope to make solar more energy efficient, and crucially more economical in production terms.
