Biomethane is an interesting source for sustainable energy systems, featuring great flexibility that translates into multiple possible applications (vehicle fuel, combined production of thermal and electrical energy, injection in the gas grid). Compared to biogas, biomethane permits greater...

The photovoltaic (PV) industry has a relevant role in terms of energy systems sustainability. The economic and environmental benefits related to its application brought the PV sector to an overall installed power of about 138GW in 2013 (+24% compared to 2012).

The production of electricity from renewable sources plays a strategic role in the future of energy because it helps to effectively manage climate change through an energy generation portfolio with lower emissions of greenhouse gases.

The balance between the demand for electricity by consumers and businesses, and environmental protection, is one of the key challenges of our society.
