A stove which uses a combination of electricity and gas reduces reliance on the grid.  Even when using a photovoltaic solar energy system, the weather may be overcast for an extended period.

One is able to cook or boil water for tea or coffee even when electricity is unavailable – no hauling out the portable stove or having to wait it out until the lights come back.  This leads to comfort and convenience.

Cost-saving benefits are also enjoyed.  One remains unaffected by electricity price hikes and we do not have to use and pay for electricity.

It’s also easier to control temperatures with gas cooking.  With a simple twist of the dial, lowering or raising the temperature instantly, is entirely possible.  This means saving time when cooking.
