5. Reflexion
5.1. The use of renewable energy has become increasingly important in recent years. While renewables are often seen as a cheaper option in the long run, transitioning to them can have significant upfront costs. It is important to carefully consider the environmental impacts of renewable energy projects and implement measures to minimize these impacts. National renewable energy markets are projected to continue to grow strongly in the 2020st
6. Hydropower
6.1. Is one of the oldest and largest sources of renewable energy, which uses the natural flow of moving water to generate electricity.
6.1.1. advantages
