Exploring Renewable Energy Sources

What are fossil fuels?

• Fossil fuels are renewable energy sources from plants.

• Fossil fuels are natural energy sources formed from the remains of ancient organisms, including coal, oil, and natural gas.

• Fossil fuels are synthetic materials created in laboratories.

• Fossil fuels are minerals found in the earth's crust.

Name three types of fossil fuels.

• biomass, nuclear, propane

• uranium, hydrogen, geothermal

• wood, solar, wind

• coal, oil, natural gas

Why are fossil fuels considered nonrenewable?

• Fossil fuels are considered nonrenewable because they take millions of years to form and are being used faster than they can be replenished.

• Fossil fuels are considered renewable because they are abundant in nature.

• Fossil fuels are nonrenewable due to their high cost of extraction.

• Fossil fuels are renewable because they can be easily replaced.

What is carbon dioxide and why is it important in the context of energy?

• Carbon dioxide is a greenhouse gas produced by respiration and combustion, important for energy as it is a byproduct of fossil fuel use and essential for photosynthesis.

• Carbon dioxide is a solid form of carbon used in construction.

• Carbon dioxide is a nutrient essential for animal growth.

• Carbon dioxide is a type of renewable energy source.

List five common types of renewable energy.

• Natural Gas

• Coal

• Nuclear

• Solar, Wind, Hydroelectric, Geothermal, Biomass

How does solar energy generate electricity?

• Solar energy generates electricity using photovoltaic cells in solar panels that convert sunlight into electricity.

• Solar panels store electricity for later use.

• Solar energy is converted into electricity using chemical reactions.

• Solar energy generates electricity through wind turbines.

What is the role of wind turbines in energy production?

• Wind turbines convert solar energy into electricity.

• Wind turbines primarily serve as decorative structures in landscapes.

• Wind turbines play a crucial role in energy production by generating electricity from wind energy.

• Wind turbines are used to store energy for later use.

Describe how hydroelectric power is generated.

• Hydroelectric power is generated by burning fossil fuels to create steam.

• Hydroelectric power is produced by solar panels converting sunlight into electricity.

• Hydroelectric power is generated by using wind to turn large blades that produce energy.

• Hydroelectric power is generated by using flowing water to spin turbines connected to generators.

What is geothermal energy?

• Electricity generated from wind turbines

• Fuel extracted from fossil sources

• Geothermal energy is the heat energy generated and stored in the Earth.

• Energy derived from solar panels

What materials are used in biomass energy?

• Wood, agricultural crops, animal manure, organic waste

• Solar panels, wind turbines, hydroelectric dams

• Coal, natural gas, nuclear fuel

• Plastic waste, metals, glass
