Radioactive atoms contain energy that pours out spontaneously as energetic subatomic particles or electromagnetic waves. As it applies to nuclear energy, many materials created during the operation of a reactor are radioactive. As they decay, they emit radiation.

Hydropower contributes significantly to the reduction of GHG emissions and to energy supply security. Compared with conventional coal power plants, hydropower prevents the emission of about 3 GT CO2 per year, which represents about 9% of global annual CO2 emissions.

Hydropower is fueled by water, so it’s a clean fuel source, meaning it won’t pollute the air like power plants that burn fossil fuels, such as coal or natural gas. In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply.

Because hydroelectric powerplants burn no fuel, operating costs are low and are immune to rising fossil fuel prices. As a result, these plants are playing a significant role in keeping electricity costs affordable for consumers, creating a positive impact on the economy.

Pros and cons of hydropower

Water quality degradation is one of the major concerns associated with developing hydroelectric facilities. The degradation in the quality of water that flows through hydroelectric dams and is held in hydroelectric reservoirs is a major concern as it effects a wide range of plant and animal life.
