Since 2010 the NiPS Laboratory proposes a yearly event to disseminate a new conceptual approach to renewable energies in the field of microenergies.But... what do we actually mean with "microenergies"?Microenergies are all those energies that are often disregarded as unimportant but instead play a significant role in our daily life. As an example… when you run out of battery in your mobile phone and really need to make that call !!! The amount of energy involved in this case is really very small compared to the energy that makes your car going but its absence appears to be very important to you…The next Micro-Energy day  will take place on the 20th of June 2015, in the framework of the 2015 European Sustainable Energy Week.We strongly encourage single individuals, groups, and institutions to join us in celebrating the Micro-Energy day. Please submit your event to micro-Energy day.
