Home Energy Savings in The Kitchen

March 22, 2009


Saving energy at home is on every one’s minds these days. The kitchen is a major energy hog until induction cooking came along.

So, how can we “go greener” in our kitchen?

Induction cooking uses 90% of the energy produced, compared to only 55% for a gas burner and 65% for traditional electric ranges.

Traditionally, when we cook, we produce heat on a stove top which then heats a pot or pan, which in turn heats (cooks) our food. So, what’s the problem? The problem is, more of heat energy is going to the cooking vessel than to the actual food itself.

Induction cooking is a method, completely different from all other cooking technologies–it does not involve generating heat which is then transferred to the cooking vessel, it makes the cooking vessel itself the original generator of the cooking heat.

An induction cookeruses induction heating for cooking. A conducting pot is placed above an induction coil for the heating process to take place. This type of cook top does not work with cooking vessels that are constructed from non-magnetic materials (e.g., aluminum or glass) . Unlike alternatives such as electric hotplates and open-grills, an induction cooker creates no heat; only the vessel used for cooking is heated.

Induction cookers are faster and more energy-efficient than traditional cook tops. Unlike traditional cook tops, the pot itself is heated to the desired temperature rather than heating the stove top, reducing the possibility of injury. Induction cookers are getting popular and less expensive than traditional cookers. According to the Department of Energy, the efficiency of energy transfer for an induction cook top is 84%, versus 71% for a smooth-top non-induction electrical unit, for an approximate 20% savings in energy for the same amount of heat transfer.

Market for induction stoves is dominated by German players, such as AEG, Bosch, Miele, Schott AG and Siemens.

Pressure cookers are another great way to save energy in the kitchen, reducing cooking time by up to 70 percent.

Green cooking is on the rise these days. No doubt about it, building green is going to be the way of the future and the appliances and way we use our homes will also adapt to a greener lifestyle. Who would have thought that you could cook without heat? Just shows how smart we can live by going green.
