USB solar charger
With the development of an increasingly connected world and the use of more and more electronic devices, specialists are predicting a sharp rise in global electricity consumption over the coming decades.
At the same time, the fight against global warming is encouraging the switch from combustion engines to electric vehicles, as is the case with cars. An increase in electricity consumption therefore seems highly likely. If these additional needs are met by non-renewable and polluting energies, the environmental challenges won't be resolved. It is therefore necessary to develop renewable sources of electricity production.
This example illustrates the possibility of powering or recharging USB-powered nomadic devices with 100% renewable electricity from the sun.
This should not blind us to the fact that the development of renewable electricity will have to go hand in hand with a reduction in waste, and even with some changes in our lifestyles. So it's always a good idea to think about the real utility of an electronic device before adopting its use, because the cleanest energy is the one we haven't consumed!
