How does energy technology work?
Energy technology encompasses various systems and processes that generate, store, distribute, and utilize energy efficiently. The specific workings of energy technology depend on the type of technology being used. Here, we will explore a few examples to provide an overview.
- Solar Power: Solar panels, also known as photovoltaic (PV) panels, are made up of semiconductor materials such as silicon. When sunlight hits these panels, the photons in the sunlight excite electrons in the semiconductor material, creating an electric current. This direct current (DC) is then converted into alternating current (AC) using inverters to make it compatible with our electrical grid or for direct use.
- Wind Power: Wind turbines consist of large rotor blades connected to a generator. As the wind blows, it causes the rotor blades to rotate. This rotation drives the generator, which converts the mechanical energy from the wind into electrical energy through electromagnetic induction. The electricity generated is then transmitted through power lines for distribution.
- Hydroelectricity: Hydroelectric power plants use flowing or falling water to generate electricity. Dams are built across rivers or reservoirs are created to store water. When released from a higher elevation, gravity pulls the water down through turbines inside the dam structure. As the water flows through these turbines, it causes them to rotate and drive generators that produce electricity.
- Geothermal Energy: Geothermal systems utilize heat from within the Earth for heating or electricity generation purposes. In geothermal heat pumps for heating and cooling, pipes filled with a refrigerant fluid are buried underground where temperatures remain relatively constant throughout the year. The fluid absorbs heat from the ground during winter and transfers it indoors for heating purposes or vice versa during summer for cooling purposes.
- Energy Storage: Energy storage technologies like lithium-ion batteries work by storing excess electricity generated from renewable sources during periods of low demand or high production and releasing it when needed later on. Batteries store electrical energy chemically and convert it back into electricity when required, providing a reliable and flexible energy supply.
These examples only scratch the surface of energy technology, as there are numerous other technologies and systems available, each with its own unique working principles. However, the common goal across all energy technologies is to harness and convert various forms of energy (solar, wind, hydrothermal, etc.) into usable electricity or other forms of energy while minimizing waste and environmental impact.
