Hydroelectric Power Plant

A hydroelectric power plant harnesses the energy of water to generate electricity. The process begins with water flowing in through six nozzles, which are aimed at buckets on a turbine wheel spinning at 500 rpm.

  • The precise design and shape of the buckets enable them to harness up to 92% of the energy from the water.
  • A splitter in the middle of the buckets divides the water jet into two pieces, allowing for efficient energy harnessing.
  • The turbine wheel is connected to a generator, which creates electricity.
  • The generator is connected to a massive 25-ton metal shaft, which turns the linear motion of the water into rotary circular motion.
  • The electricity is then distributed to homes across Europe through a vast network of pipes and wires.
  • The control room monitors and controls the entire process, ensuring that the electricity is generated and distributed efficiently.

Passive Voice with Phrasal Verbs


Explanation
In the given text, we can see the use of passive voice with phrasal verbs. Phrasal verbs are idiomatic expressions that combine a verb with a preposition or an adverb. When we use phrasal verbs in the passive voice, the preposition or adverb usually comes after the verb. For example, “is aimed at” and “is connected to” are phrasal verbs in the passive voice. The focus is on the action’s recipient rather than the doer. This grammatical structure is often used in formal or technical writing, such as in the description of a hydroelectric power plant.
