More than half the town gas we supply to cookers, laundries and restaurants is derived from Copenhagen’s own wastewater. The rest is composed of natural gas, so the less town gas you use, the less natural gas we have to put into the town gas.
Here are some good tips for saving town gas
Cook together
Eating together creates economies of scale. Consider whether you could eat together with your neighbour or family a couple of times a week. Then you turn on fewer gas burners.
Use a lid when cooking
Place a lid on the pot when cooking on your gas cooker. You retain more of the energy this way.
Cook for several days at a time
Prepare a large portion, so you have food for several days. This way you won’t have to turn on the gas burner so often and for so long.
Haybox
With some dishes, the final stages of cooking can be done in a haybox. Modern hayboxes keep temperatures high without using any energy whatsoever. An added bonus is that you don’t need to keep an eye on food that is cooking itself.
Dry your clothes on a clothesline
Does your building’s laundry have gas tumble dryers? Use warm days to dry clothes on a clothesline. That way you cut down on your consumption of gas.
Use less water when cooking
Do not fill more water than necessary into the pot. This way you save gas, water and time.
Be careful what you put in the toilet
Two thirds of your town gas is based on biogas, where we take your wastewater (sewage), treat it, process it and use it in town gas. Therefore, the “cleaner” the wastewater is, the less we have to treat it before we can use it in town gas.
We can best utilise wastewater if it only contains poo, pee and paper – to be perfectly frank. Wet wipes, cotton pads and cotton buds can get stuck in the pipes, and then we have to use a lot of resources to flush the system. Likewise, fat in your drains can create a blockage. So, think about what you throw in the toilet.
