Is it cheaper to charge your phone in the car or at home?

Written by:
Energy bills are rocketing and many people will be looking at ways to cut back on their gas and electricity use.

Next week the energy price cap will rise 54% taking average bills from £1,277 to £1,971 a year.

This coupled with rising inflation across food and fuel mean millions of people will be looking at ways to save on their bills.

Sarah Broomfield, energy expert at, shares her tips when it comes to these five energy saving questions:

Is it cheaper to charge your phone at home or in the car?

Charging your phone on a car journey is likely to cost you more in the long run, especially with current high fuel prices.

The charger in your car is effectively being run by your car engine, but converting that energy to electricity results in losses that make this method more expensive than using the electricity at home.

Is it cheaper to steam rather than boil food?

Steaming your food is more energy efficient than boiling, as it means heating less water to boiling point. It also has the added benefit of keeping more vitamins and nutrients in the food.

Using a multi-layer saucepan to cook three ingredients should use a third of the energy required to heat three separate pans, but make sure that the steam is reaching all the food and check it is cooked all the way through before eating.

Whenever cooking food or boiling water on the hob, make sure to put a lid on any saucepan, as this will dramatically reduce your energy use.

Should you leave the oven door open to let heat out?

Some heat energy will remain inside your oven once you have finished cooking, in the form of hot air, and the cooker elements.

Leaving the oven door open will let this heat out into the room, but the amount of energy released will not make a huge amount of difference to your heating bill.

This is not something you should do if you have small children or pets in the house.

Should you stop/start the hot water tap or wash dishes in a bowl?

Using a bowl in the sink will reduce the volume of hot water you run to wash up, and so decrease the amount of energy needed to heat it.

Should you turn off appliances straight after use?

All gadgets use a small amount of energy when they are left on standby, so it’s good practice to turn off devices once they have finished.

In reality, the amount of electricity used by a dishwasher or washing machine on standby is very small.
