The now extinct turnspit dog or “underdog” was a breed of terrier bred to work in the kitchen, turning a wheel for a spit, much like a hamster runs around its wheel.
The halogen oven uses heating elements that convert electrical energy into intense heat. Infrared waves and an inbuilt high-performance fan helps circulate the heat to cook the food more quickly than in a regular oven. The ovens are much smaller than their conventional rivals – and about an eighth of the cost.
Solar ovens use only sunlight for energy, yet can reach cooking temperatures of 180 – 200C.
The data we use to work out energy and water costs come from a range of reliable international sources to give an average figure. Figures are rounded up or down to the nearest whole number.
* Total amounts potentially saved do not include lighting in individual rooms, or use of secondary heating.
