Renewable and Nonrenewable Energy Flashcard

Front

What is renewable energy?

Back

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

Front

What is nonrenewable energy?

Back

Energy that comes from sources that will run out or will not be replenished in our lifetimes, such as fossil fuels (coal, oil, natural gas) and nuclear energy.

Front

How does a hydroelectric dam generate electricity?

Back

By using falling water to turn turbines.

Front

What is the main advantage of using renewable energy?

Back

It helps reduce pollution and is sustainable.

Front

What is solar energy?

Back

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

Front

What are wind turbines?

Back

Devices that convert the kinetic energy of wind into mechanical power, which can then be converted into electricity.

Front

What is the role of turbines in energy generation?

Back

Turbines convert kinetic energy from moving fluids (water, air) into mechanical energy, which is then converted into electricity.

Front

Why is solar energy considered clean?

Back

It uses the sun, which doesn’t run out, and does not pollute the air.

Front

What is geothermal energy?

Back

Energy derived from the heat stored beneath the Earth's surface.

Front

What is biomass energy?

Back

Energy produced from organic materials, such as plant and animal waste.
