BREAK DOWN CO2 CONSUMPTION! saving, as well as economic, will also be environmentally friendly!
In Italy it has been estimated that in order to produce a Kwh of energy, a quantity of CO2 (more responsible for the greenhouse effect) is generated by about 0.52 Kg / Kwh (source lifegate.it).
For example, if we consider replacing the traditional lighting of a typical city, we can deduct savings in terms of CO2 entering the atmosphere of thousands of tonnes.
To obtain the same environmental advantage, it would be necessary to reforest enormous surfaces, considering 2mq of Kg of Co2 injected into the atmosphere needed for compensation (source Lifegate.it).
