    Are Induction Cooktops Energy Efficient?



September 2018


Get a handle on induction cooking to see if it’s a must-have addition to your kitchen. With its green credentials and other benefits, it may just be the cooktop you’re looking for.

From home cooks to master chefs, those with a love of food are clued on to the quirks of their cooking appliances inside-out. They know exactly how long it takes to soft boil an egg in a pan or bake a sponge cake to fluffy perfection. Sometimes, despite this long-acquired cooking wisdom, it’s time for a change.

Whether your current oven or cooktop is on its last legs or you’re designing a whole new kitchen, it could be time to reconsider the way you cook food. Particularly if you’re interested in making your kitchen more energy efficient.

This is where induction cooktops come in. These incredibly energy efficient cooktops are wowing chefs and home cooks with their speed and efficiency. Let’s take a look at why.

How do induction cooktops work?

Basically, a standard electric or gas cooktop transfers heat (or conducts heat) from the cooktop to the pot or pan. Whereas, an induction cooktop ‘switches on’ an electromagnetic field when it comes into contact with your pot or pan (as long as the cookware contains a ferrous material like iron or steel). The heat comes on fast and instantly starts cooking the contents.

Given the speed of heating, induction cooktops can take a bit of getting used to and they may require a new set of pots and pans. However the energy savings they deliver could outweigh these disadvantages in the long run.

Why are induction cooktops more energy efficient?

While induction cooktops still use electricity to produce the electromagnetic field, they draw much less energy than electric coil or hotplate cooktops, and even ceramic cooktops. This is mainly due to the fact that induction cooktops don’t have to heat up an element to transfer heat. So, this means no heat or energy is wasted.

This, plus the fact that food is heated up much faster so the appliance doesn’t need to be on for as long, means that they are generally considered to be the most energy efficient option. Indeed, induction stovetops have been found to be twice as efficient as traditional gas and electric stovetops, primarily due to energy not having to be converted to heat

Cooking tips to make your induction cooktop even greener

There are many ways to save in the kitchen. Just a few simple changes to your cooking habits could reduce the energy consumption of your cooktop:

  • Always cook with a lid (preferably glass so you don’t have to keep taking it off)
  • Choose pots and pans with flat bases to maximise the surface area in contact with the cooktop
  • Use a smaller pan, if you’re cooking for one or two people
  • Try to match the size of the pan’s base with the size of the cooktop
  • Turn the heat down – cook with the lowest power possible to achieve the result you’re after

The final word

Induction cooktops can be much safer, they are easier to keep clean, give you complete control over the heating of food … and ultimately, they save on electricity. If you’re ready for a change in the kitchen, it could be worth considering.
