The savings offered by using LEDs has caught the attention of businesses, governments and individuals in towns and cities around the world. Energy efficiency is increasingly important for businesses, governments and individuals as the cost of energy has increased in sharply in recent years.
There are dozens of examples from around the world of businesses, organisations and individuals adopting LED technology to become more energy efficient. At Pasadena City College in California a $2.4 million LED project is near completion on campus which will change all the fluorescent tubes to LED lights. Vice Chair of the Associated Students Sustainability Committee Jason Carman went on to say that “The savings already are around $20,000 a month.”
In Galt, California they have retrofitted 184 traditional streetlights with LED lights and plan to change a further 376. Mayor Jason Behrmann said that “The project will result in significant cost savings to the city due to the increased efficiency and longer life of the bulbs.” With the lighting upgrade, the city expects to save 101,266 kilowatt-hours or $12,152 yearly in energy costs and reduce greenhouse gas emissions by 32 tons annually.
In Taiwan the government has invested heavily in the production and use of LED lighting. Under the projects, the government is expected to spend about NT$2.8 billion to install more than 326,000 LED street lights around the island.
In Singapore fifty pedestrian overhead bridges have been fitted with LED lights. The lights at these bridges will remain switched off between midnight and 7am. But, a motion sensor and Intelligent Lighting Detection System (ILDS) will switch these lights on automatically when someone walks up the stairs to the bridge.
The use of these lights and motion sensors will reduce monthly energy consumption by up to 50 per cent. And that’s potential savings of up to S$30,000 annually in electricity bills. The Land Transport Authority plans to expand the use of LED lighting to new commuter facilities, such as pedestrian underpasses and bus shelters. It will also install LED lighting at 350 other existing pedestrian overhead bridges as well as commuter facilities where the florescent lights are due for replacement.
Istoria LED understands that one of the biggest barriers to widespread LED adoption was the initial investment. However the cost LED lights has been halved over the last three years and this continues to fall, making LED lighting much more accessible and popular.
