New technology is the key to the meeting the coalition's pledge to lead the "greenest government ever", David Cameron has said. The prime minister was announcing the publication of an online league table which will be updated daily, to allow the public to see which departments were cutting energy use the most.

Struggling to tackle the acute power crisis in the state, Shobha Karandjale, the new energy minister, is planning to encourage energy conservation as purchasing electricity is proving to be a costly affair. The government spends an average of Rs 350 crore a month to purchase power from private producers to meet the power crisis.

British Telecom, Belgacom, France Telecom-Orange, OTE, Telefonica and Turk Telekom among others, have joined heavyweights such as Fujitsu, Hewlett-Packard, IBM, Intel, Microsoft, Vodafone and Cisco in the voluntary plan to help cut carbon emissions. The new signees bring the number of companies participating to 36.

Norwalk and Darien residents looking to dispose of used compact fluorescent light bulbs, commonly called CFLs, have a variety of options to take advantage of. At a news conference at the Home Depot location on Connecticut Avenue in Norwalk Thursday, state Senator Bob Duff (D-Norwalk) and Norwalk Mayor Richard Moccia detailed the services available to those in the area.

The vehicle that has been Dubbed Superbus, is as long as a normal bus and has the same height as a conventional SUV, being capable to carry about 23 passengers. According to the designers, the new electric bus is a “future vision of sustainable public transport.” It also features an aerodynamic design to create a sustainable, fast and comfortable mode of public transport.

The Renault DEZIR, or the desire of any new-age, science-fiction addict, hot-blooded obsessed rock star (or less) is the masterpiece of Renault’s design team and one of the best car designs (in terms of sexiness) I have ever seen. Renault DeZir occupies a central piece at this year’s Paris auto show, with all the other sports cars fading into anonymity (ok, well, perhaps Jaguar’s new masterpiece or Citroen’s Survolt will keep up).

Beacon Power, a major player in flywheel energy storage, is now working with U.S. Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) on the development of a next-generation of flywheel storage. The new flywheel storage system is expected to be able to store 4 times as much energy as present flywheels, and at one-eighth the per kilowatt-hour cost.

Utilizing what we have in a wiser way could lead us to something worth it. As the famous line goes, “everything has its purpose” no matter how small or big it is. It also includes waste products such the awful pet poop, specifically dog poop. In Cambridge, Massachusetts, a dog park hasn’t been considering these dog poop a waste at all. In fact, in has turned out to be a very useful.

Solar cells currently used are mostly bulky and made from silicon and other non-recyclable materials, hence they’re not as green as they should be. Mimicking nature might be a solution to this problem. More exactly, North Carolina State University researchers have prototyped a water-based solar cell, mimicking the functioning of a leaf, to produce electricity.

This weekend, automobile maker Jaguar introduced it’s newest supercar at the Paris Motor Show. The new concept vehicle sets new standards for green vehicles and showcases technology for the future of electric motoring. The Jaguar C-X75 concept car is a first of it’s kind to sport both an electric powered engine in concert with a jet turbine engine, which tops out in at an impressive speed of 205 mph.

Designers have come up with a new portable wind turbine that is very easy to be transported and put into function by just one person. Dubbed the “Mobile Wind Turbine”, it includes a hybrid carrier that uses electricity harnessed from wind energy to run.

All new investments must undergo independent assessments and government reviews on whether they are energy-saving or not before being approved by regulators, the National Development and Reform Commission, China's top economic planner, said yesterday in a statement on its website.

A team of Ukranian and American scientists have discovered that by using structures called ferroelectric nanowires, they can generate electricity from a temperature difference. This concept is now new, but rather uses different approaches and materials. It can harvest energy by using the temperature difference between materials and/or ambients.

Ahead of the 2020 deadline for constituent parts of the UK to hit renewable power targets, Scotland has raised its ambitions for real-terms energy saving by switching to eco-friendly alternatives.

A delegation representing 15 Finnish enterprises said here on Tuesday they wanted to look for local partners to develop renewable energy, wastewater treatment, industrial waste management and other environmental technologies. Some of the Finnish companies introduced their clean technologies at a seminar held here on Tuesday were Neste Oil Corporation, Cargotec, GD Power, Kemira, Fincumet, YIT and Outotec.

Apart from awareness in all the company, LaVie has also decided to invest in new technology as a way to reduce energy consumption. The deputy general director reveals that her company will replace all energy-consuming air compressors by smaller ones that fit the capacities of the current production lines. In addition, it has changed its lighting systems to LED lamps, and reduced water use as a way to cut energy consumption as well.

The two researchers tried to combine spintronics (electronics that use the spin of electrons to read/write data) with thermoelectricity, which transforms heat into electricity through the Seebeck effect. The spin-Seebeck effect (the conversion of heat to spin polarization) had been observed in action in 2008, but only on a metal rod, not on a semiconductor. They called their new heat-to-electron spin discovery “thermo-spintronics.”

The new nano-ceramics would be key components in the next generation of capacitors. Like batteries, capacitors store energy, but there the resemblance ends. Batteries are designed to collect energy over a relatively long period of time, then release it at a low, constant rate. Capacitors charge and release large amounts of power very quickly. The basic principle has been around since the 18th century, but until recently one roadblock has been how to reduce them down to an efficient size.

The two companies, in cooperation with PetersenDean Roofing and Solar Systems, announced a partnership earlier this year to pre-install solar panels at no additional cost to homebuyers at The Preserve new home community. Last Friday, September 17, Toll Brothers hosted the official ribbon-cutting ceremony to open the community to the public.

The UK environmental group Carbon Trust and Cambridge University’s Cavendish Laboratory have jointly formed a new company called Eight19 concentrating on the development of new organic photovoltaic (PV) technology that could make the installation of solar cells cheaper and easier.
