Answer 2

Answer:

(3) geothermal

Explanation:

• Solar energy, wind, the heat of the earth (geothermal), plant materials (biomass), ocean currents, the energy of the tides, and other non-depletable or naturally replenishable energy resources are examples.
• The percentage of heat energy converted to work is the thermal efficiency of an energy station.
• Geothermal extracts heat energy from beneath the earth's surface.
• Some of this heat rises to the surface in the form of geysers or hot springs.
• The thermal efficiency of geothermal power plants is low, hovering about 7-10%.
• Hence, Geothermal (7-10%), Nuclear (33%), wind (35-45 %), Solar (50%). Geothermal has the least efficiency of electrical power generation.
