We are so used to turning on the lights or charging our smartphones at the flick of a switch that it is easy to forget that the production and distribution of energy is the result of a sophisticated and complex process, as is the work required to keep electricity grids functioning properly and safely.
In fact, electricity distribution networks are often located in places that are inaccessible because of the environmental conditions. In our mountains, one common problem in winter is snow on the pylons, which can turn into ice and cause major disruption to the community.
