Depending on the type of energy source and production process involved, power generation also produces wastes that are harmful to the environment and human health. For example, carbon dioxide and heavy metals (e.g. mercury) are emitted by coal-fired power stations, and radioactive waste is produced in nuclear power plants.
Thus CO2 and heavy metal emissions as well as radioactive waste are continuously generated indirectly in the production, operation and disposal of all products needed to produce light.
In the context of electricity consumption in Austria in 2017, 61 grams per kWh of CO2 were emitted (2017 Electricity Labelling Report, E-Control). In continental Europe, 343.84 grams per kWh of CO2 and 0.679 milligrams per kWh of radioactive waste were generated in 2015 (Entso-E Mix 2015, E-Control).
Heavy metals and radioactive waste are harmful environmental toxins, and excessive CO2 in the atmosphere promotes the greenhouse effect, which accelerates global warming. Responsible and efficient lighting accordingly makes a valuable contribution to environmental and climate protection!
