All Flashcards
Why is wind energy considered renewable?
Wind is a naturally replenishing resource, unlike fossil fuels, ensuring a continuous supply.
Explain energy conversion in wind turbines.
Kinetic energy of wind is converted to mechanical energy by rotating turbine blades, then mechanical energy is converted to electrical energy by a generator.
What are the environmental benefits of wind energy?
Reduced greenhouse gas emissions, less air pollution, and decreased reliance on fossil fuels.
What are the environmental drawbacks of wind energy?
Potential harm to birds and bats, noise pollution, and visual impact on the landscape.
Why are wind turbines mounted on tall towers?
To access stronger, more consistent winds at higher altitudes, increasing energy production.
How does intermittency affect wind energy integration?
Requires energy storage solutions and grid management strategies to ensure a reliable electricity supply.
Why is energy storage important for wind energy?
Wind is variable, so storage ensures a consistent electricity supply when wind is not blowing.
How does wind energy contribute to job creation?
The wind energy industry creates jobs in manufacturing, installation, maintenance, and related sectors.
What factors determine the suitability of a location for wind energy?
Strong, consistent winds, proximity to transmission lines, and minimal environmental impact.
How does wind energy compare economically to fossil fuels?
Wind energy is becoming increasingly cost-competitive, offering a viable alternative to fossil fuels.
How can strategic placement of wind farms mitigate environmental impact?
Avoid sensitive habitats, migration routes, and densely populated areas to minimize harm to wildlife and reduce noise pollution.
How can bird-deterrent technologies help protect wildlife?
Using radar, acoustic deterrents, and blade painting can reduce bird and bat collisions with wind turbines.
How can energy storage solutions improve wind energy sustainability?
By storing excess energy generated during windy periods, ensuring a consistent electricity supply and reducing reliance on fossil fuels.
How can community engagement improve wind energy projects?
Involving local communities in the planning and decision-making process can address concerns and promote acceptance of wind energy projects.
How can smart grid technologies enhance wind energy integration?
By optimizing the distribution of electricity and managing intermittency, ensuring a reliable and efficient electricity supply.
How can international collaboration promote wind energy development?
Sharing knowledge, resources, and best practices can accelerate the deployment of wind energy technologies worldwide.
How can policy incentives support wind energy growth?
Tax credits, subsidies, and renewable energy mandates can encourage investment in wind energy projects.
What are the steps involved in generating electricity from wind?
Wind turns turbine blades -> rotation converts kinetic energy to mechanical energy -> generator converts mechanical energy to electrical energy -> electricity is stored.
