Materials and means of production
The environmental impact of energy . A few examples

Materials are needed to build the systems that harness energy sources: wind turbines, photovoltaic panels, nuclear power plants, etc. But for the same material, the greater the quantity used, the greater the environmental impact. But for the same material, the greater the quantity used, the greater the environmental impact. It is interesting to compare a number of energy sources in this respect. The table at 2 shows the amount of concrete and steel required to produce 1 GWh/year for some of them. It should be noted that this is in terms of energy produced, not installed capacity. These estimates were made in the reference
