Renewable Energy Concepts Assessment

Front

What is solar energy?

Back

Solar energy is the energy harnessed from the sun's rays, which can be converted into electricity or heat.

Front

What are photovoltaic cells?

Back

Photovoltaic cells are devices that convert sunlight directly into electricity using the photovoltaic effect.

Front

What is concentrated solar power (CSP)?

Back

Concentrated solar power (CSP) uses mirrors or lenses to focus a large area of sunlight, or solar thermal energy, onto a small area to generate electricity.

Front

What is the primary disadvantage of wind turbines?

Back

One primary disadvantage of wind turbines is the disruption of migratory birds' paths.

Front

How do hydroelectric dams generate electricity?

Back

Hydroelectric dams generate electricity by allowing water to flow through channels, spinning a turbine connected to a generator.

Front

What happens to nonrenewable energy resources as energy demands increase?

Back

As energy demands increase, our supply of nonrenewable energy resources decreases.

Front

What is biomass energy?

Back

Biomass energy is energy produced from organic materials, such as plant and animal waste.

Front

What are the environmental impacts of hydroelectric dams?

Back

Hydroelectric dams can destroy land and ecosystems behind the dam when initially submerged.

Front

What is the role of a turbine in energy generation?

Back

A turbine converts kinetic energy from moving water or air into mechanical energy, which is then converted into electricity.

Front

What is wind energy?

Back

Wind energy is the energy obtained from the movement of air, which can be converted into electricity using wind turbines.
