In some countries, Energy Efficiency Portfolio Standards require energy suppliers to meet a specific proportion of their energy demand through EE (DEFRA, 2007). Energy suppliers may also help reduce energy demand (and electricity bills) by encouraging households to generate their own electricity. Eventually, it may give customers the opportunity to sell power produced in the home back to the grid. In Mauritius, for example, the Government encourages innovation to enable households to produce electricity based on emerging technologies for renewable energy.
