Sustainable Energy Technology includes renewable energy sources (such as solar energy, wind energy, and energy from biomass) and technologies designed to improve energy efficiency.
A transition to a society based Sustainable Energy is necessary to be self-sufficient, meet the growing global demand for energy, and address the threat of climate change caused by greenhouse gas emissions. This transition will require fundamental innovations affecting the world's energy landscape.

Securing a sustainable energy future implies an energy transition that will require a new generation of dedicated engineers and researchers capable of developing, optimising, and integrating sustainable energy sources including solar power, wind power, and energy from biomass. Because of the intermittency of these sources storage of energy is an important factor for success. This requires innovative batteries and research into hydrogen as an energy source. New technologies need to be integrated into existing power networks and market structures. The design of new forms of energy distribution, energy market structures, and smart grids is necessary to satisfy the energy needs of modern societies.
