The use of renewable energy has become increasingly important in modern society as the demand for clean and sustainable power continues to grow. Solar energy is one of the most widely used sources, where sunlight is converted into electricity using solar panels, making it a clean alternative to fossil fuels. Wind energy is another important source, generated through wind turbines that convert kinetic energy from wind into electrical power. Hydropower also plays a major role by using the movement of water to produce electricity. These renewable sources help reduce harmful emissions, decrease dependence on non-renewable resources, and support environmental protection. Although they may require high initial investment and depend on natural conditions, continuous technological development is improving their efficiency and reliability.
