1. Solar Power Generator (Photovoltaic - PV):
- Solar panels: Made up of photovoltaic (PV) cells, which absorb sunlight and generate an electrical current.
- Inverter: Converts the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity that can be used by homes and businesses.
- Mounting system: Holds the solar panels in place and ensures proper orientation towards the sun.
- Grid connection: The solar power system can be connected to the electrical grid, allowing excess electricity to be sold back to the utility company (net metering).
2. Wind Power Generator (Wind Turbine):
- Blades: Capture the kinetic energy of the wind and convert it into rotational energy.
- Rotor: Attached to the blades, rotates with the wind.
- Nacelle: Encloses the generator, gearbox, and other mechanical components.
- Tower: Supports the wind turbine and elevates it to capture stronger winds.
- Grid connection: The wind turbine is connected to the electrical grid to deliver electricity.
3. Hydropower Generator:
- Dam: Controls the flow of water and creates a reservoir.
- Penstock: A pipe that carries water from the reservoir to the turbine.
- Turbine: The kinetic energy of the flowing water spins the turbine blades.
- Generator: Converts the rotational energy of the turbine into electricity.
- Grid connection: Hydropower generators are typically connected to the electrical grid.
4. Geothermal Power Generator:
- Geothermal reservoir: A source of hot water or steam located deep in the earth.
- Well: Drilled into the geothermal reservoir to extract hot water or steam.
- Turbine: The heat energy from the extracted water or steam is used to generate steam, which drives the turbine.
- Generator: Converts the rotational energy of the turbine into electricity.
- Grid connection: Geothermal power plants are generally connected to the electrical grid.
These renewable energy generators rely on natural resources that are constantly replenished, ensuring a sustainable and environmentally friendly source of electricity. By utilizing these natural forces, green power generators play a crucial role in combating climate change and reducing our dependence on fossil fuels.
