6 Questions
What is the main source of energy for wind power generation?
Kinetic energy from wind
What is the main source of energy for solar power generation?
Sunlight
What is a common challenge for both wind and solar power in terms of electricity generation?
Dependence on weather
What is the main disadvantage in terms of space utilization for wind power generation?
Take up a lot of space
What is a shared positive aspect of both wind and solar power in relation to environmental impact?
Do not produce pollutants

Decreasing every year
Study Notes
- Wind power is generated through wind turbines, often placed in exposed areas with strong winds. Each turbine has a generator that converts kinetic energy from wind into electrical energy.
- Solar power is produced through solar cells, often in the form of solar panels, which generate electric currents directly from sunlight. They work effectively in small devices and remote regions.
- Both wind and solar power have low running costs and don't produce pollutants, including carbon dioxide.
- Both wind and solar power have high upfront costs and the processes of making them can produce pollutants, particularly in the production of solar cells.
- Wind and solar power are dependent on the weather, meaning they don't generate electricity when the wind doesn't blow or the sun doesn't shine. They cannot increase supply during peak demand.
- Wind turbines take up a lot of space and some people find them unsightly and noisy.
- Neither wind nor solar power damages the environment.
- The costs of both wind and solar power are decreasing every year.
Test your knowledge about the differences and similarities between wind power and solar power, including their generation processes, environmental impacts, and cost trends.
