Fight climate change with LED bulbs

By BizLED Bureau

September 11, 2015: Shifting to energy-efficient LED lighting offers three major benefits. A switch to LED lighting will help combat climate change, save energy, and improve people?s lives through increased well-being, safety, and productivity.

Reduce air pollution

LED bulbs help reduce air pollution, making the air healthier to breathe, particularly for those who suffer from asthma, heart disease and respiratory ailments.

Less energy consumed

Most energy still comes from coal-burning power plants. About 12% of the energy we use at home for lighting. An LED bulb uses 70-90% less energy than a conventional bulb, limiting the need to burn that much more coal. Today, an LED lamp produces about 100 lumen of light per watt, which makes it about 20 times as efficient as an incandescent lamp and four times as efficient as the fluorescent tube.

If every household replaces just one light bulb with one certified LED blub, we would save enough energy to light two million homes for a whole year. We can also prevent greenhouse gas emissions equivalent to that of 550,000 vehicles.

Currently, lighting accounts for 19% of global electricity production, according to the IEA (International Energy Agency). Around two-thirds of current lighting is based on older technologies developed before 1970. A full switch to the latest energy-efficient LED lighting combined with smart control and management systems could provide very significant energy savings of up to 80% in many applications. Worldwide, the switch to LED lighting could save energy consumption for lighting by 40%. This equates to approximately 130 billion euros per year in running costs and 670 million tons of avoided carbon dioxide emissions, the equivalent output of about 640 medium sized power plants. Over two-thirds of the benefit could be achieved in the commercial and industrial world.

Money saved

Any time we save energy, we save money. Though an LED bulb costs a little more up front, it can save in electricity costs over the lifetime of the product. Ane bulb can last as long as 22 years or 25,000 hours.

LEDs provide light in lumens, most LED bulb packages will give you the wattage the LED is replacing. For example, this LED bulb replaces a 60 watt incandescent.

In addition to the light of the bulb, the label makes a difference. Most people who go shopping for an LED bulb probably look for the words “energy-saving,” which any company can slap on any bulb. What they really need to be looking for is the Energy Star label. Bulbs that have earned the Energy Star save significant amounts of energy and money because they are independently certified to use less energy, undergoing extensive testing to ensure high quality and the performance you expect.

How India can help in climate change

India should fully adopt this technology, and replace all other sources of lighting with LEDs. This will help the country to save 15% of its electricity consumption and help to contribute in climate change, and in the process, improve the lives of millions of people in rural India. India can also try to accelerate the growth of an LED lamp-producing industry in the country.

The government should ensure that all villages should use only LEDs for lighting. The electricity that will be saved can be used to subsidise LEDs for consumers. The government should also work out financing schemes to mitigate higher capital outlays required on LEDs.

Pin It


  1. LED lights address only one side of waste in lighting. Over the past 100 years cheaper lights have simply meant more lights and a growth in light pollution. We also need to look at how the light we generate is used. Currently we waste much of it in uplighting,glare, over lighting and lighting spaces all night that are used a few minutes per week.As examples gas stations are lit 10 times more than they were a few years ago and up to 100 times what is neede to see.
