wind energy Flashcards
(15 cards)
What is wind energy?
The conversion of the kinetic energy of wind into mechanical power, which is then transformed into electricity through the use of wind turbines.
What role does wind energy play in combating climate change?
It reduces dependence on fossil fuels and produces no greenhouse gas emissions during operation.
How do wind turbines generate electricity?
Large blades mounted on a rotor spin when wind flows over them, turning a central shaft connected to a generator, which converts mechanical energy into electrical energy through electromagnetic induction.
What are the two types of wind farms?
- Onshore
- Offshore
What are the advantages of wind energy?
- Renewable and sustainable
- No greenhouse gas emissions during operation
- Low operational and maintenance costs
- Land surrounding onshore farms can be used for agriculture or grazing
- Job creation in manufacturing, installation, and maintenance
What is a significant limitation of wind energy?
Intermittency—wind does not blow constantly, leading to variable power output.
What types of pollution can wind farms cause?
- Visual pollution
- Noise pollution
How can wind turbines negatively impact wildlife?
They can particularly harm birds and bats.
What is a drawback of the initial cost of wind turbine installation?
The initial cost is high.
What advancements are contributing to the growth of wind energy?
- Advancements in technology
- Improved turbine efficiency
- Growing public support
True or False: Wind energy is completely reliable as a standalone energy source.
False
Fill in the blank: Wind energy is a clean and _______ energy source.
inexhaustible
What is the main process by which a generator converts energy in wind turbines?
Electromagnetic induction
What is one of the dual benefits of land surrounding onshore wind farms?
It can often still be used for agriculture or grazing.
What is a crucial pillar in the transition toward a cleaner, more sustainable energy future?
Wind power
