then boils water to create steam, driving turbines connected to generators.
What is the role of a transformer in an electrical grid?
✔✔A transformer adjusts the voltage of electricity, stepping it up for efficient transmission over
long distances and stepping it down for safe use in homes and businesses.
How does wind energy generate electricity?
✔✔Wind energy generates electricity by converting the kinetic energy of moving air into
mechanical energy, which turns a turbine connected to a generator.
What is the purpose of energy efficiency in energy systems?
✔✔Energy efficiency aims to reduce energy consumption by using less energy to perform the
same task, thus lowering environmental impact and reducing costs.
