Answer:
Source of energy
1. Solar Energy
2. Geothermal energy
3. Wind energy
4. Biomass
5. Hydropower
Uses
1. Solar power is energy from the sun that is converted into thermal or electrical energy.
2. Geothermal energy is also used to directly heat individual buildings and to heat multiple buildings with district heating systems.
3. To Generate Wind Power. One of the most popular uses of wind energy is to generate electricity.
4. All biomass can be burned directly for heating buildings and water, for industrial process heat, and for generating electricity in steam turbines. Thermochemical conversion of biomass includes pyrolysis and gasification.
5. Hydropower, or hydro energy, is a form of renewable energy that uses the water stored in dams, as well as flowing in rivers to create electricity in hydropower plants. The falling water rotates blades of a turbine, which then spins a generator that converts the mechanical energy of the spinning turbine into electrical energy. Hydroelectric power is a significant component of electricity production worldwide.
Advantages
1. Renewable Energy Source, Reduces Electricity Bills, Diverse Applications, and Low Maintenance Costs.
2. A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy
3. Renewable & clean source of energy, Low operating costs, and Efficient use of land space.
4. Renewable, Waste reduction, and Reliability.
5. Renewable source of energy, pairs well with other renewables and can meet peak electricity demand.
Disadvantages
1. Weather Dependent, Solar Energy Storage is Expensive, and Uses a Lot of Space.
2. Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.
3. Intermittent, Noise and visual pollution, and Some adverse environmental impact.
4. High cost, space requirements, and see environmental adverse impact.
5. Some adverse environmental impact, Expensive up-front and lack of available reservoirs.
