Solar power is the process of converting energy from sunlight into electricity. This can be done using photovoltaic (PV) panels, which are made of semiconductor material that absorbs sunlight and creates an electrical current. Solar power is a clean and sustainable source of energy, but it is intermittent, meaning that it is not available at all times.
Wind power is the process of converting the kinetic energy of the wind into electricity. This can be done using wind turbines, which are large towers with blades that rotate in the wind. Wind power is a clean and sustainable source of energy, but it is also intermittent.
Hydropower is the process of converting the energy of flowing water into electricity. This can be done using hydroelectric dams, which impound water and use the force of the water to generate electricity. Hydropower is a clean and sustainable source of energy, but it is limited to areas with significant water resources.
Biomass is the process of converting organic matter into electricity. This can be done by burning biomass, such as wood or agricultural waste, in a power plant, or by converting it into biogas through a process called anaerobic digestion. Biomass is a renewable source of energy, but it is not considered to be carbon-free because it produces greenhouse gases when burned.
Geothermal power is the process of converting heat from the earth's interior into electricity. This can be done by drilling deep into the earth and extracting hot water or steam, which is then used to generate electricity. Geothermal power is a clean and sustainable source of energy, but it is limited to areas with high geothermal activity.
