Liên Hợp Quốc đã kêu gọi các nước trên thế giới nên cấm sử dụng loại bóng đèn sợi đốt truyền thống nhằm đối phó với hiện tượng biến đổi khí hậu phức tạp hiện thời. Theo nghiên cứu của Liên Hợp Quốc (LHQ), các loại đèn compact CFC hay các loại đèn LED có ưu điểm tiết kiệm năng lượng từ 20% đến 50% và có tuổi thọ cao gấp 10 lần so với những loại bóng đèn sợi đốt cùng công suất.

The solar industry called on Congress on Tuesday to extend a contentious grant program in the lame-duck session that it says produced 20,000 solar jobs in a year and half and helped to jump-start the U.S. clean energy economy. The U.S. Treasury's "Section 1603" Renewable Energy Grant Program, part of the $787 billion anti-recession stimulus of 2009, is slated to run out at year's end.

Nhà sản xuất Toshiba (Nhật Bản) vừa hé lộ thông tin về một số mẫu TV mới nhất của hãng, với tên gọi Power TV được tích hợp sẵn pin sạc bên trong, có khả năng hoạt động liên tục trong vòng 2 giờ mà không cần cắm điện. Theo tiết lộ của Toshiba, dòng Power TV sẽ có ba mẫu sản phẩm với tên gọi là PC1, PS1 và PB1 với kích cỡ màn hình từ 24 inch tới 32 inch. Hai trong ba chiếc TV này sẽ sử dụng công nghệ chiếu sáng đèn nền LED để làm giảm năng lượng.

One of my favorite science fiction ideas is in a short story called Light of Other Days about something called “slow glass.” Light took decades to pass through. In this story, the idea was that people could buy glass windows that took so long for the light to pass through, that they could nostalgically watch long gone scenes, such as their children playing outside as toddlers long after they had gone off to college, or green fields with horses where now ugly cities grew.

Snohomish County is pledging to cut energy use at its facilities by 10 percent as part of a Snohomish County PUD’s “Energy Challenge” campaign. The county is joining more than 150 local businesses and nearly 3,000 residential utility customers who have vowed to make comparable energy cuts. The goal is to save money and cut greenhouse gases, while reducing overall demand on the PUD’s energy supply.

CMU aims to save more than $600,000 over the next two years by reopening a gas turbine at the Central Energy Facility. The gas turbine was installed in 1991, but was shut down in 2002 because it was not economically efficient, said Steve Lawrence, associate vice president of Facilities

Những dòng sản phẩm mới của Megaman có kiểu dáng mới lạ, độc đáo; tuổi thọ lên đến 40.000 giờ; tiết kiệm đến 80% điện năng; giảm lượng khí thải CO2 đáng kể. Ngoài ra, khi hết tuổi thọ của bóng đèn, sản phẩm có thể duy trì 90% độ sáng, giảm thiểu đáng kể tia cực tím và bảo vệ sức khỏe con người…

Ngày 19-11, công ty chuyên sản xuất thiết bị chiếu sáng ở Bắc Mỹ, Osram Sylvania, thông báo sẽ đưa vào sản xuất thương mại bóng đèn LED được thiết kế để thay thế bóng đèn dây tóc nóng sáng 60 watt.

Today Osram Sylvania, a North American lighting manufacturer, announced that it will be commercially producing an LED light bulb designed to replace a 60-watt incandescent bulb. Millions of 60-watt incandescent bulbs are currently sold each year, but according to the Energy Independence and Security Act of 2007, these light bulbs must be phased out by 2014.

Các đi-ốt hữu cơ phát sáng được cho rằng có triển vọng trở thành loại đèn chủ yếu của thế hệ mới, những đèn chiếu sáng có diện tích lớn với hình dạng tuỳ ý và có thể tích hợp uyển chuyển vào thiết kế nội thất. Tuy nhiên, sự đắt đỏ của OLED đang cản trở việc đưa ý tưởng nói trên vào cuộc sống: Một đèn chiếu dạng đĩa phẳng đường kính 8cm có giá 250 euro (~6,731 triệu đồng).

Thanks to a $3 million federal stimulus grant given to the Utah Energy Program, solar panels will be installed in every school district in the state, at 73 Utah schools in all. Students will be able to track online how many kilowatt hours of energy their solar photovoltaic arrays generate, and teachers at the schools will receive training to teach students about solar, wind and geothermal technologies.

Nhiều người cho rằng cứ loại nào mới nhất là tốt nhất. Tuy nhiên, thực tế là mỗi loại đèn xe hơi đều có cả ưu và nhược điểm. Hãy dành chút thời gian tìm hiểu về cả ba: halogen, xenon và LED.

Cars and trucks race down the highway, turn off into town, wait at traffic lights and move slowly through side streets. Electricity flows in a similar way -- from the power plant via high voltage lines to transformer substations. The flow is controlled as if by traffic lights. Cables then take the electricity into the city centre. Numerous switching points reduce the voltage, so that equipment can tap into the electricity at low voltage. Thanks to this highly complex infrastructure, the electricity customer can use all kinds of electrical devices just by switching them on.

Thailand will be supplied with some more solar panels for a new power plant, as a result of the signed agreement between the authorities and Suntech Power Holding Co. The latter will provide approximately 9.43MW worth of panels to the installation. The project is owned by Bangchak Petrolem and is scheduled to be finalized by the end of next year. Once online, the solar power plant should provide around 44MW of clean electricity

This technology has many advantages. Drying room is completely tight, therefore, seafood is isolated from fuel and is not spoiled. Especially, according to this technology, remaining heat can be withdrawn or adjusted based on different products through the heat supply equipment. Thus, apart from assuring product quality, drying seafood with steam reduces 10 times energy costs compared to traditional technologies.

The European Hydrogen Association (EHA) and the European Regions and Municipalities Partnership for hydrogen and fuel cells (HyRaMP) have called for accelerated support from the EU, national and local governments to ensure a sustainable build-up of hydrogen infrastructure in Europe. Both organizations stress the need to integrate hydrogen infrastructure development into the EU’s current energy and transport infrastructure plans.

Making a cellphone battery last ten times longer is a first target for a large research project that IBM, Infineon and a number of European universities unveiled on Wednesday. The new research project, called Steeper, also aims to decrease the energy needs of other electronic devices like TV sets or supercomputers by 10 times when active, and to virtually eliminate power consumption when they are in standby mode.

A new clean tech company called Totempower Energy Systems Ltd. has come up with an easy way to put wind power within the grasp of everyday homeowners. The company is developing new micro-wind turbines that are designed for close quarters and non-disruptive installation, but the real key to getting more micro-wind turbines into consumers’ hands is the company’s “ease of ownership” plan which provides a soup-to-nuts service including site selection and connecting the turbine to the home electrical system.

VietnamPlus and Siemens signed a partnership agreement in Hanoi on Oct. 21 whereby VietnamPlus will be the media sponsor for Siemens Green Technology Journalism Award 2010. This award is created for the first time in ASEAN in order to acknowledge and reward journalists for excellent reporting on energy efficiency, industrial productivity and sustainability issues. It is open to print and online media from Indonesia , Malaysia , the Philippines , Singapore , Thailand and Vietnam.

A New Zealand firm is hoping to beat rivals to Britain's lucrative boiler replacement market with its energy-efficient product and says an IPO (initial public offering) in Europe could be on the cards as it ramps up production. Whisper Tech, controlled by New Zealand state power group Meridian, expects to be profitable within a year and is examining its funding options over the next 12-18 months as it moves into mass production.
