Question 1

What is a key benefit of solar photovoltaic systems?

Accepted Answer

They generate electricity from sunlight

Answer

Solar photovoltaic (PV) systems are designed to convert sunlight directly into electricity using semiconductor materials. This process, known as the photovoltaic effect, provides a clean and renewable source of power. A key benefit is the production of electricity without emissions, reducing reliance on fossil fuels and lowering carbon footprints.

Question 2

Which renewable energy source relies on wind to produce power?

Accepted Answer

Wind energy

Answer

Wind energy is a renewable energy source that harnesses the kinetic energy of wind to generate electricity. Wind turbines capture this energy, converting it into mechanical power that drives a generator. This process produces clean electricity without emitting greenhouse gases, making it a sustainable alternative to fossil fuels.

Question 3

What is the primary resource used in geothermal energy systems?

Accepted Answer

Earth’s heat

Answer

Geothermal energy systems utilize the natural heat stored within the Earth's crust. This heat originates from the planet's core and radioactive decay. Geothermal power plants tap into underground reservoirs of hot water and steam to generate electricity, while geothermal heat pumps use the stable underground temperature for heating and cooling buildings.

Question 4

Which of the following is considered a form of biomass energy?

Accepted Answer

Wood pellets

Answer

Biomass energy refers to energy derived from organic matter, such as plants and animal waste. Wood pellets are a common form of processed biomass, made from compressed sawdust and other wood waste. They are burned to produce heat or electricity, offering a renewable alternative to fossil fuels, as trees can be replanted.

Question 5

What is net metering in renewable energy systems?

Accepted Answer

It credits users for feeding power back to the grid

Answer

Net metering is a billing mechanism that allows consumers who generate their own electricity, typically with solar panels, to send excess power back to the utility grid. When they do, they receive credits on their electricity bill, effectively offsetting their consumption from the grid. This encourages the adoption of renewable energy systems by making them more financially viable.
