There has been a growing attention and a great interest on the geothermal resource as a source of renewable energy during the last few decades. The decision to focus on a renewable resource such as geothermal energy was undertaken with a special eye to environmental sustainability, contributing to the reduction of carbon dioxide emissions and fine dust deriving from air conditioning. According to the commitment made by most of the countries during the international Kyoto treaty in this branch, the use of low-depth geothermal energy was chosen in order to obtain sustainable resources both from an energy and environmental point of view.

The LED technology (Light-Emitting Diodes) represents the evolution of lighting, in which the light’s generation is obtained by using semiconductors instead of using a filament or a gas. LED lighting has several advantages over other lighting technologies available on the market:

• important energy savings
• longer life (average life: 50,000 hours)
• high luminous efficiency (120 lm/W compared to 13, 16 and 50 of incandescent, halogen and fluorescent lamps)
• it does not emit warm light, thus optimizing efficiency
• maintenance not necessary

However, the most noteworthy aspects related to the eco-sustainability concept that the APG group decided to bind with are:

• silica powder content and not harmful substances
• total absence of light pollution
• minimization of UV and IR emissions

In the Pharma and Cosmetic divisions, 40% of the car uses a hybrid power supply, which combines two different technologies, an electric motor and a petrol engine. In addition to the advantages in economic terms such as consumption, the most important aspect concerns the issue of emissions, which with this technology reaches minimum environmental impact thresholds: it is possible to travel in electric mode up to 50 km/h without producing any CO2 emissions.

The photovoltaic effect is a physical phenomenon that occurs within the single solar panel and allows the production of clean energy. It occurs when the photovoltaic cells, made of a semiconductor material, usually silicon, are contaminated (the technical term is “doped”) with boron and aluminum on one side and with arsenic, phosphorus and antimony, on the other.

This creates a zone with prevalence and one with absence of electrons inside the cell. The light that is not reflected or transformed into heat enters the panel and breaks the bonds of the crystalline structure, producing a charge shift within it. Thanks to this last phenomenon, solar energy is transformed into electricity.
