Micro-hydro power systems are smaller-scale hydroelectric systems that typically generate power for a single community or a small number of homes. They often use small rivers or streams to produce electricity.

Water-based renewable energy sources, such as hydro power, tidal, wave, and ocean thermal energy, have significant potential for contributing to the global energy mix.

Tidal power offers a predictable and consistent source of energy due to the regularity of tides. It can generate electricity as the tide comes in and goes out.

A technology called Ocean Thermal Energy Conversion (OTEC) uses the temperature difference between warm surface water and cold deep water to produce electricity. This temperature gradient drives a turbine system.

Dams are used to store water in a reservoir. When the water is released from the dam, it flows through turbines, creating mechanical energy that is then converted into electricity.

The construction of dams for hydroelectric power can disrupt ecosystems, alter natural water flow, affect fish migration, and lead to the displacement of communities living near dam sites.

Pumped-storage hydro power facilities store energy by pumping water from a lower reservoir to a higher reservoir during periods of low electricity demand. When demand rises, water is released back down to the lower reservoir through turbines, generating electricity.

Run-of-river hydropower plants generate electricity without the need for a large dam or reservoir. They utilize the natural flow and elevation drop of a river, diverting a portion of the water through a canal or penstock to drive turbines and produce electricity.

Challenges with wave energy include the harsh marine environment affecting the durability of equipment, difficulty in predicting wave patterns accurately, and the high cost of developing and maintaining wave energy technologies.

Some desalination plants use a process called reverse osmosis, which requires a significant amount of electricity to remove salt from seawater. However, innovative designs integrate technologies to recover energy during the desalination process, potentially offsetting some of the energy consumption.

Wave energy is captured using devices such as buoys or floating platforms that move with the waves. The motion drives generators, converting the kinetic energy of the waves into electrical energy.

Hydropower generates electricity by using the force of flowing or falling water to turn turbines connected to generators. The spinning turbines convert the kinetic energy of water into electrical energy.
