Renewable energy sources are those that are replenished naturally and can be used without depleting them. These include solar, wind, hydro, geothermal, and biomass energy.

Wind turbines convert the kinetic energy of wind into mechanical energy, which is then used to generate electricity. The blades of the turbine are designed to capture the wind’s energy, which turns a shaft connected to a generator.

Solar energy is a clean, renewable, and abundant source of energy. It does not produce greenhouse gas emissions, requires little maintenance, and can be used in remote areas without access to electricity grids. It also reduces dependence on fossil fuels and helps to mitigate climate change.

Solar panels are made up of photovoltaic cells that convert sunlight into electricity. When sunlight hits the cells, it causes a flow of electrons, which creates an electric current. This current can be used to power homes and businesses or stored in batteries for later use.

Geothermal energy is heat from the Earth’s core that can be used to generate electricity or heat buildings. It is a reliable and renewable source of energy that can be used in areas with hot springs or geysers. Geothermal power plants use steam or hot water from deep underground to drive turbines and generate electricity.

Biomass energy is energy derived from organic matter, such as wood, crops, or waste. It can be used to generate electricity or heat buildings. Biomass energy is a renewable source of energy that reduces waste and can be carbon neutral if managed sustainably.
