The rebound effect describes behavioural, or other, responses to the introduction of high efficiency equipment for saving energy. These responses tend to offset the beneficial effects of the efficiency measures taken, so that the achievable savings are reduced. For instance an optimized control system can reduce energy consumption and costs. On the other hand the feeling of having so efficient equipment can cause demand for higher room temperatures and subsequently increase the energy consumption.
Renewable energy is energy that is derived from natural processes (e.g. sunlight and wind) that are replenished at a higher rate than they are consumed. Solar, wind, geothermal, hydropower, bioenergy and ocean power are sources of renewable energy. The role of renewables continues to increase in the electricity, heating & cooling and transport sectors.
