If you want to make a difference, support one of the companies below, all of which use profits to fund solar power in developing countries. In Africa, millions use dangerous expensive kerosene or chop firewood, which causes deforestation. Far better (in hot sunny climates) is free solar power, to bring heat and light, for cooking and studying.
Little Sun is a solar lamp that gives 5 hours of bright light (or 40 hours of dim light), after 5 hours of charging. For each one bought, one is donated to a rural household in Ethiopia.
Turn off lights when not needed to avoid light pollution and prevent bird strike.
Power a Life makes pocket phone chargers and Wee Pal Power Bank (made from recycled plastic bottles). Again, profits help solar charities.
Wonderbag is an African-made slow cooker, which needs no electricity. Just bring a pot of food to the boil, and food cooks, using heat retention technology.
The Little Coffee Company female farmers up to 125% more than Fair Trade minimum. It donates solar lamps to remote areas of Africa, for each pack sold.
Avoid caffeine for pregnancy/nursing. Use a sink protector mat to avoid grounds clogging sinks (bin grounds, as acids could harm compost creatures).
I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until the oil and gas run out, before we tackle that. I had I had more years left. Thomas Edison (American inventor who died in 1931). He would not be that impressed.
