DONG NAI — The southern province of Dong Nai has installed 76 traffic lights using solar energy. Duong Danh Quy, head of the province's Traffic Safety Committee said the province was the first in the country to use solar panels to supply power for traffic lights. "During the trial, the traffic lights were as reliable as traffic lights wired to the power supply and constituted a valuable energy saving for Bien Hoa City," he said. The plan was initiated in 2007 by the committee and piloted in several places around the city. The solar powered posts have been installed on national highways 1A, 51, 20 in the province and on some city streets. Quy said the posts have capacity to store enough power for two days' operation and they are easy to install, because they require no excavation of the road surface. The cost for a post is around VND120 million (US$6,282), taken from the committee's fund from traffic fines. Quy said solar powered posts would replace all public grid wired posts in … [Read more...] about Dong Nai gets solar traffic lights

VietNamNet Bridge – Dang Dinh Thong, deputy director of the Institute for Clean Energy, tells the newspaper Tuoi Tre (Youth) about Viet Nam’s big potential to develop renewable energy sources.Dang Dinh ThongViet Nam is a tropical country with great potential for the development of renewable energy, but not many enterprises have expressed their interest in development. Why?We currently have 46 investors expressing their interest in developing wind energy, but only 3 or 4 projects have been executed. For example, in Bac Lieu southern province, a 99.2 MW wind energy plant by has recently been completed. Meanwhile the Tuy Phong wind energy project in the southern province of Binh Thuan has a design capacity of 120 MW, but currently it operates only at one third of its capacity.There are fewer solar investment projects. For example, in Con Dao Island there is one project with designed capacity of 30 MW. However, a few investors have expressed their interest in developing solar … [Read more...] about VN officials ignorant on renewable energy
Years ago, when mentioning Truong Sa (Spratly) Islands people used to think of its scorching sun and harsh winds. But now those unfavorable weather conditions have changed into a green energy resource, which has contributed greatly to beautifying the islands with a sparkling outlook. Visiting Truong Sa Lon Island nowadays, visitors would be surprised at the shining electrical light all over the island at night. Since the power system has been operated from renewable solar and wind energy, electricity has been accessed to every household and even to each small lane on the island. Formerly the only source of power came from a generator, hence the use of electricity was limited, said Major Dinh Trong Tham, Deputy Chief of Truong Sa Lon Island military force and in charge of logistics services for the island. Electricity from the generator is just enough for lighting the lamps for about three hours and a half, from 6pm to 9.30 pm – just sufficient for the residents’ and … [Read more...] about Green energy lightens up the Spratly Islands
VietNamNet Bridge – The Hoa Binh provincial Science & Technology Analysis, Testing and Service Center has received the technology transfer to implement the project on using solar energy and diesel engine to generate electricity for remote areas. The solution that allows saving energy Hoa Binh province in the north of Vietnam has weak wind energy resource. Though it has profuse hydraulic power sources, but the most potential sources all have been exploited. Meanwhile, the livestock breeding is still underdeveloped; therefore, it’s not the right time to think of using biogas to generate power. Of the clean energy sources, scientists have found out that the solar energy is the most potential. According to the Hoa Binh province’s Hydrometeorology Center, the province has 1,545 sunny hours every year, a higher number if compared with the other localities in the country. Therefore, scientists have decided that using solar energy to generate power is the most … [Read more...] about Solar energy for remote areas, why not?
Apple Inc will buy about $850 million of power from a new California solar farm to cut its energy bill, the iPhone maker said on Tuesday as its stock market value closed above $700 billion for the first time. The First Solar Inc plant, with the capacity to power the equivalent of 60,000 homes, will be used to supply electricity for Apple's new campus in Silicon Valley, and its other offices and 52 stores in the state, Chief Executive Tim Cook said at a Goldman Sachs technology conference in San Francisco. Cook addressed investors as Apple's stock market value closed at $710.74 billion for the first time, buoyed by record sales of big-screen iPhones and a December-quarter profit that was the largest in corporate history. Apple was already the world's largest publicly traded company by stock value. The plant in Monterey County, California will also power an Apple data center in Newark, California that already relies on solar power. "We expect to have a very significant savings because we … [Read more...] about Apple in big solar power deal, market cap closes over $700 billion
