Renewable Energy Flashcard #2

Front

What is the process by which a photovoltaic system converts sunlight into energy?

Back

A photovoltaic system converts sunlight into electrical energy.

Front

Which subatomic particle is responsible for creating electric current?

Back

Electrons are the particles that move to create current.

Front

What is a significant challenge associated with geothermal energy?

Back

Geothermal energy is not practical for year-round use.

Front

What process do plants use to convert sunlight into chemical energy?

Back

Photosynthesis is the process by which plants convert sunlight into chemical energy.

Front

How do geothermal plants harness energy?

Back

Geothermal plants harness energy by turning hot water from underground into steam, which then turns a turbine.

Front

What is renewable energy?

Back

Renewable energy is energy that is collected from resources that are naturally replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Front

What are the main types of renewable energy sources?

Back

The main types of renewable energy sources include solar energy, wind energy, hydroelectric energy, biomass, and geothermal energy.

Front

What is the role of solar panels in renewable energy?

Back

Solar panels convert sunlight directly into electrical energy through the photovoltaic effect.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally, while non-renewable energy sources, like fossil fuels, are finite and will eventually deplete.

Front

What is the significance of the electron in electricity generation?

Back

Electrons are essential for electricity generation as their movement through a conductor creates an electric current.
