Chris Huhne threatened to get heavy-handed with gas and electricity providers on Tuesday, warning that he would step in if the industry failed to tell customers about price rises.The energy secretary hit out at providers who “put up their prices without telling you for three months”.

According to the Pedegopress release , “The announced battery-fuel cell hybrid system is compatible with all existing Pedego bicycles and batteries. For every 1.5 lbs. of weight a rider carries, an additional 700 watt-hours of energy is available (compared to ~350 watt-hours for an ultra-high performance lithium-polymer battery at a weight of 7 lbs.).

Các nhà khoa học Australia đã nghiên cứu cách sản xuất các tấm pin mặt trời bằng cách “in” các đơn vị quang điện biến quang năng thành điện năng lên đế polyme và tạo ra những thay đổi lớn trong việc sử dụng điện mặt trời.

The inventor says his device can cut the energy use by 25%. Moreover, it can prove itself healthy for those who suffer from asthma, allergies, of whatever age or sex. CleanAir supposedly removes particles, viruses, ozone, bacteria, organic solvents, hydrocarbons and cigarette smoke from the air.

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.

Within two years, three White Sands Missile Range employees have saved more than 4,000 miles of use on their vehicles by riding their bicycles to and from work at least twice a week. Shane Cunico, Phil Simpson and Kurt Austin, who all work at Army Research Laboratory at WSMR, have been riding their bicycles together to work for the last 18 months.

Vertical axis wind turbines have recently been revived by a few innovations made to them by scientists all over the world. Sauer Energy is one of them, and their turbine has a high efficiency because it’s designed to maximize the drag, so the blades are moved more efficiently by the wind.

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.

Last year, the Ocean Power Technologies (OPT) company has developed a tidal power generator that has now been connected to the energy grid at the Marine Corps Base Hawaii as part of the firm’s program with the US Navy to test wave energy technology, giving the US their the first-ever grid connection for a wave energy device.

The phase-out of incandescent light bulbs is part of the EU's strategy to cut greenhouse gases by 20% by 2020. Replacing the old lamps with more efficient models is expected to reduce energy consumption for lighting by 60% in the EU, equivalent to saving 30 million tons of CO2 pollution every year.

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.

If, in common sense, a buck saved is a buck earned, this proves all the more significant in energy savings, when a sum invested may result in higher profits and higher benefits. If, for an individual, energy saving merely means to avoid money burning big holes in his or her pocket, then for a company, it means better returns and better business efficiency, and for an economy, there are even greater dimensions of cost-effectiveness.

Realizing that natural resources are limited, Holcim Vietnam Limited since 2003 has aimed at sustainable production development by increasing the use of waste materials as main energies to replace fossil fuels at its Hon Chong cement plant in Kien Giang Province.

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.”

Light behaves differently in macro- and nano- scale environments, and this could be a starting point for those researchers who want to improve the solar cells’ efficiency. It was a starting point for some Stanford engineers, who found out that light ricocheting inside an ultra-thin polymer film solar cell behaves differently than if the film wasn’t so thin. The difference is enormous.

From 2006 to 2010, the project "Promoting Energy Conservation in Small and Medium Scale Enterprise - PECSME", funded by the Global Environment Fund and managed by the Ministry of Science and Technology, has implemented 201 projects in the brick manufacturing industry, 144 projects in ceramics - porcelain, 81 projects in the food processing industry, 35 projects in the textile-garment and 38 projects in the paper industry.

At the Vietnam - Russia Intergovernmental session which was held in mid-September, the Vietnamese Minister of Industry and Trade Vu Huy Hoang, and Russian Minister of Industry and Trade V.Khristenko officially signed the Roadmap for the implementation of Vietnam - Russia cooperation projects in energy sector (Energy cooperation roadmap).

According to "Nikkei" of Japan issued on 22nd September, the Itochu Corporation of Japan and Qatar Petroleum are having final discussions on building a petrochemical production complex in Vietnam. According to Qatar Vice President and Minister of Energy, these two groups would build a petrochemical production complex in Long Son (Vung Tau) with a total investment of about $ 4 billion.

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.
