All Flashcards
Define wind energy.
Energy harnessed from the kinetic energy of moving air to generate electricity.
What is a HAWT?
Horizontal Axis Wind Turbine: the most common type of wind turbine.
What is a VAWT?
Vertical Axis Wind Turbine: a less common type of wind turbine.
Define kinetic energy.
The energy of motion; wind possesses kinetic energy due to its movement.
Define renewable energy.
Energy from sources that are naturally replenished, like wind and solar.
Define intermittency in wind energy.
The characteristic of wind energy being variable and not always constant.
What is a wind turbine generator?
Converts mechanical energy of rotating shaft into electrical energy.
What is pumped storage?
A method of electricity storage.
Define clean energy.
Energy that does not produce harmful emissions or pollutants.
What is noise pollution?
Excessive or disturbing noise that disrupts normal life.
Define wind energy.
Energy harnessed from the kinetic energy of moving air to generate electricity.
What is a wind turbine?
A device that captures the kinetic energy of the wind and converts it into mechanical energy, which can then be used to generate electricity.
Define kinetic energy.
The energy possessed by an object due to its motion.
What is a generator?
A device that converts mechanical energy into electrical energy using magnets and coils of wire.
What are HAWTs?
Horizontal Axis Wind Turbines, the most common type, with blades rotating around a horizontal axis.
What are VAWTs?
Vertical Axis Wind Turbines, less common, with blades rotating around a vertical axis.
Define renewable energy.
Energy from sources that are naturally replenishing, such as wind, solar, and hydro.
Define intermittency in the context of wind energy.
The characteristic of wind energy being variable and not always constant, leading to fluctuating energy output.
What is noise pollution?
Excessive or disturbing noise that can negatively impact human and animal health.
What is visual pollution?
The negative aesthetic impact of human-made structures on the natural landscape.
What is the effect of wind turbines on bird and bat populations?
Can cause injury or death due to collisions with turbine blades.
How does wind energy impact greenhouse gas emissions?
Reduces greenhouse gas emissions by displacing fossil fuel-based electricity generation.
What are the visual impacts of wind farms?
Wind farms can alter the landscape, leading to visual pollution concerns.
What are the effects of wind turbine noise?
Wind turbines can produce noise pollution, disturbing nearby residents and wildlife.
How does intermittency affect grid stability?
Variable wind energy output can challenge grid stability, requiring backup power sources or energy storage solutions.
What is the effect of wind energy on air pollution?
Reduces air pollution by decreasing the need for fossil fuel combustion.
How does wind energy impact local economies?
Creates jobs, stimulates investment, and generates revenue for local communities.
What is the impact of wind farms on land use?
Requires large areas of land, but land can often be used for other purposes like agriculture.
What are the effects of wind energy on energy independence?
Increases energy independence by diversifying energy sources and reducing reliance on imported fuels.
How does wind energy affect the cost of electricity?
Can lower electricity costs over time as wind energy becomes more cost-competitive with fossil fuels.
