In recent years, countries such as China, Japan, Taiwan and Korea have encouraged the private and municipal use of LEDs. The aim is to reduce electricity consumption to free up energy for industrial sectors. Now India, with its rapidly developing economy, has seen the low energy benefits of LED lighting.
The Indian economy is growing at a rate of about 9% per year. To sustain this growth, energy production must increase by up to 400% within the next two decades. This is a costly problem. The Indian government has therefore looked at ways to improve energy efficiency. It has decided LEDs are a major part of the solution.
A report from the Indian Bureau of Energy Efficiency (BEE) has stressed how LEDs can lower the demand for electricity. The report believes a greater use of LED bulbs by private citizens could cut electricity consumption in homes by 30%. And municipal LEDs could reduce street lighting energy use by 50-70%.
In partnership with The Climate Group, a not-for-profit organisation, the BEE is supporting various pilot trials with LEDs. LED lighting has begun to appear in streets around the country. And the results are positive. Pedestrians and drivers like them. In one survey, drivers even said LEDs improve road visibility at night.
India looks set to become yet another Asian user and promoter of LEDs. Interest in the technology is strong. Since 2009, for example, the country has hosted the LED Expo in New Delhi. Organisers expect the latest Expo to be the biggest yet, and to attract visitors not just from Asia, but from around the world. LEDs are capturing international interest.
