Energy Tip
of the Day!

Energy star rated compact fluorescent Lamp (CFL) should be the choice in household lighting applications From the extraordinary Gazette notification No. 1611/10 of July 22,2099, the display of the Energy Label  on every CFL was made mandatory. The energy label consists of star rating which varies from  1 star   to 5star higher the number of the star greater the energy efficiency of the CFL. Accordingly CFLs having an energy label with 5 star are  most energy efficient compared to the  CFLs having 1star to  4star rating. By repacking a 1star CFL with 5star CFL with 5-7 watts lower in wattage the same light out put can be gained. Purchasing a CFL with 5 star rating about 5-7 watts  can be cut down At present LED Lamp technology has improved rapidly end in parallel the price of LED lamps have come down to  an affordable Scale for the domestic consumer. Sri Lanka has already introduced performance stety and Minimum Energy performance  standers (MEPS) for LED Lamps introduce for which satisfy MEPS.

Reduce your carbon footprint

Reduce Your Carbon Footprint

Your carbon footprint is the sum of all emissions of carbon dioxide (CO2), which were induced by your activities, usually calculated for the time period of a year.

Almost everything that you do emits some amount of carbon dioxide. Carbon dioxide is a greenhouse gas which contributes to the phenomena global warming and climate change. Therefore, we should attempt to cut down on our personal carbon dioxide emissions, if we are to save our planet. In order to cut down on CO2, we need to know how much we generate, in the first place. To help you with this quest, the SEA has developed an ‘easy-to-use’ carbon calculator on Microsoft Excel spread sheet application.

You can download the tool here. If you have any difficulties in using it up, please drop a mail to We would be glad to help you.

How do your actions contribute?

The emission of carbon dioxide from the activities you carry out, vary according to intensity of the activity. For example, if you go to school by car, your contribution would be much more than going to school by bus or train or even in a school van. Assume that the distance you’re your home to school is 10 km, so if you go by car, perhaps, there would be no more than four people in the vehicle. Therefore, the amount of carbon dioxide emitted from the car is divided by four, to calculate the impact of a single person. Similarly, if you travel this distance by bus, there would be about 80 passengers in the bus. Therefore, the amount of carbon dioxide emitted from the bus is divided by 80, to calculate the impact of a single person. Hence, the more you use public transport, the more environment friendly you are!

Following are the amounts of carbon dioxide emitted from various fossil fuel and electricity. Note it, even electricity is produced by burning oil and coal in Sri Lanka, therefore, it is not always ‘clean’.

Some activities and the typical amounts of carbon dioxide they emit are shown below.

Fuel Unit CO2 emissions
Electricty kg/kWh 0.71
Diesel kg/l 2.74
Gasoline kg/l 2.28
LPG kg/kg 2.73
Kerosene kg/l 2.52
Firewood kg/kg 1.51
