Active solar energy systems use which energy source?

Active solar energy systems use which energy source?

• A. Wind energy
• B. Solar energy
• C. Geothermal energy
• D. Fossil fuels

Answer: (B)

Active solar energy systems rely on capturing sunlight and using devices to convert it into usable energy. Solar radiation is collected by equipment such as photovoltaic panels that generate electricity or solar thermal collectors that heat water or air, often with pumps or fans to move the heat where it’s needed. This approach uses mechanical means to convert solar energy into practical power, unlike passive solar design which relies on building layout and materials to trap heat without moving parts. Other energy sources don’t fit because wind energy comes from moving air, geothermal energy uses heat from the Earth’s interior, and fossil fuels come from burning hydrocarbons.
