This chapter illustrates two practical applications of the SD4SEA design approach and tools, describing how they have been used by companies, practitioners and academics in different countries as part of the LeNSes project.

Historically, the reaction of humankind to environmental degradation, especially since the second half of the last century, has moved from an end-of-pipe approach to actions increasingly aimed at prevention.

The world is facing a strong evolution due to the advancement of information and communication technologies that set the knowledge technologies at the base of productivity, competition and power.

A key contemporary query is the following: within the current social, environmental and economic crisis, which are the opportunities for innovate towards sustainability? Do we know any offer/business model capable of creating (new) value, decoupling it from material and energy consumption? In other words, is there any alternative to significantly reduce the environmental impact of traditional production/consumption systems?.

We argued in previous chapters that Distributed Renewable Energy (DRE) generation is a promising approach towards sustainable energy for All.

We understood in the previous chapters that Sustainable Product-Service Systems (S.PSS) applied to Distributed Renewable Energy (DRE) represents a win-win opportunity to extend the access to sustainable energy to All.

The method developed within the LeNSes project is called Method for System Design for Sustainable Energy for All (MSD4SEA).

In the previous chapter, we introduced that Distributed Renewable Energy (DRE) is the most promising model to bring sustainable energy to All.
