Wider access to reliable electricity would lead to less use of kerosene lighting and diesel generators, which are currently common in the developing world. [ 163 ] Infrastructure for generating and storing renewable electricity requires minerals and metals, such as cobalt and lithium for batteries and copper for solar panels. [ 164 ]
Water is required for all life, but since ancient times, mankind has also employed this natural resource for other specifically human productive uses. Millennia ago man learned to navigate on water, learned to dam and divert it for irrigation and build aqueducts and canals to carry it where possible, and learned to convert the power of moving water to mechanical energy to perform work.
