In attempting to provide for as many of our own needs as we can we decided to replace our gas cooker with a portable electric induction cooker.

According to an article I read recently, induction cookers are actually less efficient than a gas hob - but that does assume an electric grid efficiency of 40%. Being that we produce most of our own electricity with our grid interactive solar system the losses would be much less. The heat transfer loss of gas is much higher than induction, a lot of the heat goes around the pot and not into it - the induction cookers are more efficient in that area.

Another factor that we have considered is where gas comes from. Increasingly, fracking is a source of gas, and is …
