Energy Efficiency

Energy efficiency is a key driving force in meeting India’s environmental and climate goals. We work closely with large and small industries and the buildings sector to help improve their energy performance. We have demonstrated a range of technologies and practices that have helped small and medium enterprises in India to reduce their carbon footprint and improve their profitability. Other significant efforts include supporting the Indian government’s Perform Achieve and Trade (PAT) scheme to promote energy efficiency in large industries.

In an effort to promote energy efficiency in air conditioning, the government may issue an advisory to all AC manufacturers and commercial buildings to keep the default temperature setting at 24 degrees Celsius. A common misconception is that setting the thermostat at 18 degrees will cool down a room faster. However, that’s not true. It will take the same amount of time for the room to reach 26 degrees-which is significantly cooler than the average current outdoor temperature of 40 degrees in Delhi-whether you set the temperature at 18 degrees or 26 degrees.

How India’s taxi fleet can go electric

India has 14 of the 15 most-polluted cities in the world, says the latest World Health Organization report. One of the ways to clean up the air will be to go for emission free electric vehicles (EVs). By pushing EVs, like China has done, India could leapfrog to the next generation of motor transportation and a green economy. India has surplus electricity generation capacity and an additional 50,000 MW is in the pipeline. So electricity for EVs would not be a constraint. The technology for charging stations is available and the investment for setting up a charging station is modest.


Don’t tinker with the clock to save energy

August 10, 2011

On 23 March 2011, all clocks in the UK were turned forward by an hour marking the start of Daylight Saving Time (DST). The clocks will be turned back on 30 October 2011. The objective is to save energy by educing the use of artificial light and maximizing the use of daylight over a period of seven months. While this has been the practice for many years in countries situated in the upper part of the northern hemisphere and the lower part of the southern hemisphere, DST is hardly practised in countries situated closer to the equator.


Energy performance benchmarking

We assist industries in reducing their energy consumption through audits at the plant level. We undertake technology assessments of energy and environmental performance for different industrial sectors and develop or promote energy efficient and environment friendly technological solutions.

Energy efficient and environment-friendly solutions

We develop and promote energy efficient technologies and environment friendly solutions for industries. The main objective is to enable supply chains to reduce fuel consumption, efficient resource utilization and enhance environmental performance.
