As the current world population stretches to over 7 billion, the world energy consumption sky rockets over 140000TWh, which will continue to increase in the future. The current world energy supply depends on the exploitation of fossil fuels such as coal and petroleum. Coal is often branded as a ‘dirty’ energy source because of its carbon emission. However, methods have been introduced to make ‘clean coal’, such as chemically washing minerals and impurities from the coal and gasification. Green renewable energy is the green alternative to our future energy demands. Green energy such as biomass, wind energy, ocean energy and solar energy are among the most exploited energy sources. Biomass is one of the newest among green energies. Biomass is produced in gasifiers and in abundance. Next, Wind turbines such as HAWT and VAWT are the primary machines that can harness the mighty wind energy. The installed wind power had increased in recent years and shows no sign of slowing down. Aerodynamic wind turbines have to be applied in installed wind power to increase the efficiency. Other than that, with the installation of wave energy capturing buoys, the maximum harvesting of ocean energy can be started. Lastly, energy from the Sun can be harvested in mainly two systems – Solar thermal energy and photovoltaics. Energy storage have been the second most important after the harnessing of green energy. Storage of solar and wind energy at small and large scales are vital especially when there is no sunlight or wind blowing.
