In general, “Green Energy” includes modern biomass energy conversion technologies, geothermal heat, electricity production, solar photovoltaic , convert the bio gas/ or Natural gas to Biodiesel & to biowax , storage the electricity by new technology and solar thermal electricity production .
A wide variety of technologies are available or under development to provide affordable, reliable, and sustainable energy services from renewables. All Green Energy sources can be converted to electricity. Only a few of them can be used to produce solid, liquid, or gaseous fuel directly, as well as heat. Some of the major sources are intermittent, e.g., solar and wind energy, which can create challenges in adopting these sources while maintaining the reliability of the overall energy supply, depending on how widely they are used.
