Question: Is electromagnetism sustainable? If not, can it be ‘made’ in a more sustainable way?

Joanna Barstow answered on 21 Nov 2019:

There are sustainable ways of making electricity. All that needs to happen to make electricity is to make a simple generator, which is basically just a coil of wire spinning between some magnets. The coil can be made to spin using wind, wave or tidal power, for example, but it’s more often done using fossil fuels at the moment, which is what is problematic.
