Whilst our solar ovens use no fuel and are completely powered by the power of the sun, our energy efficient stoves require fuel but are approximately 75% more efficient than an open fire. Solar ovens heat up to around 180 degrees Celsius and are used for sterilising water as well as cooking. The choice of distributing either a solar powered oven or building an energy efficient stove is made by our project managers on the ground, based on factors such as the immediate environment of the receiving family and local customs.
