Q: I think I use a lot of electricity for my cooking. I like to cook meals, which require long cooking times, like beans, stews and samp. What can I do to save energy?
A: Soaking your dry beans overnight before cooking is one way, but some people complain that this would affect the taste. Another way to save electricity when cooking is to make use of the fantastic Wonderbag! It’s actually a kind of donut-shaped pillow, filled with insulating material. After you’ve brought your beans or stew to boiling, put your pot into the Wonderbag, cover it and wait until food is ready! As simple as that. Read what Nontando writes about her wonderbag

Or use a solar oven 🙂
Hi Dani, I agree! It all depends where and how you live.
One particularly attractive advantage of the Wonderbag, is that you can pop the pot of food into the Wonderbag and leave your home, while the food cooks. The other advantage is that the Wonderbag doesn’t take up a lot of room. Solar cookers are quite space intensive and will require someone to watch over the cooking process.
