Renewable energy systems

Definition

Renewable energy systems are technologies and methods that harness energy from naturally replenished sources, such as sunlight, wind, water, and biomass. These systems play a crucial role in promoting sustainable development by providing cleaner alternatives to fossil fuels, reducing greenhouse gas emissions, and decreasing dependence on non-renewable resources. By integrating renewable energy into the energy grid, they contribute to economic growth while also safeguarding the environment for future generations.
