Hydroelectric power plants are key in moving to a greener energy future. They can quickly change how much power they make. This helps with using more renewable energy sources like wind and solar.
Also, hydroelectric projects help with water storage. They protect water tables and reduce flood and drought risks.
“Hydroelectricity is considered a fundamental instrument for sustainable development, aligning with the concept of ‘development that addresses people’s needs without compromising the capacity of future generations to address their own needs.'”
In summary, hydroelectric power is vital for renewable energy. It provides clean and reliable energy for our growing needs while protecting the environment.
Geothermal Energy: Tapping into Earth’s Heat
Geothermal energy uses the Earth’s heat to make power and heat homes. It’s a clean energy source that helps us move towards a greener future.
Geothermal Power Plants
These plants tap into the Earth’s heat to create steam. This steam turns turbines to make electricity. They work all the time, no matter the weather.
Dry-steam plants have been around since 1911, in places like Italy. Flash-steam plants are found in volcanic areas, like Iceland and the Philippines.
Geothermal Heat Pumps
Heat pumps use the ground or water to heat and cool buildings. They can go as deep as 10 to 300 feet. This makes them very efficient.
For example, Ball State University in Indiana uses one to save about $2 million a year. This shows how effective they can be.
New technology is making geothermal energy even better. It could power up to 60 gigawatts of electricity and over 17,000 heating systems by 2050. Geothermal energy is key to our clean energy future.
