Classification table of sustainable energy.

Type	Power generation mode	Advantage	Common production capacity range
Solar energy	Solar radiation is converted into electricity or heat energy by solar panels or solar thermal energy systems	The unlimited solar energy supply and low carbon emission are suitable for various applications	1–10 kW/m2
Wind energy	Through a wind turbine, the blades of the turbine are rotated by wind to generate electricity	The unlimited wind energy supply and low carbon emission are suitable for large-scale and distributed systems	1–5 MW/turbine
Waterpower	Power is generated by driving a hydraulic turbine by water flow	It is efficient, renewable, reliable, and suitable for various terrains and scales	1–100 MW/dam
Geothermal energy resources	It rises from the underground hot rock layer by hot water or steam and then generates electricity by steam turbine	It is sustainable and low-carbon emission, suitable for tropical and volcanic areas in specific areas	1–10 MW/well
Biomass energy	Electricity is generated by burning, fermenting, or gasifying organic materials	Renewable and widely available raw materials are helpful for waste management	1–20 MW/biomass plant
