The sun is arguably one of the humanity’s most important tool for survival. It gives off practically unlimited amounts of light that is used by plants to generate energy and animals for heat. It can be used to generate electricity with solar panels, hot water with solar hot water heaters, and many other uses. Even though technology can be very useful, for example gas ovens, natural and simple technologies like solar ovens can reduce fossil fuel use or even replace fossil fuels in places that don’t have abundant resources, and it’s an enjoyable project. The materials used can mostly be found locally from recycled sources which makes it even more sustainable.
