Exploring Energy Sources

What is a renewable energy source?

• Energy generated from nuclear reactions

• A renewable energy source is energy that is generated from natural processes that are continuously replenished.

• Energy derived from fossil fuels

• Energy that cannot be replenished

Name one type of non-renewable energy source.

• natural gas

• solar energy

• wind energy

• coal

How does solar energy work?

• Solar energy is harnessed by converting sunlight into electricity using photovoltaic cells.

• Solar panels are used to store heat for winter.

• Solar energy is generated by burning fossil fuels.

• Solar energy is produced by wind turbines.

What is wind energy and how is it generated?

• Wind energy is the energy obtained from the wind, generated using wind turbines that convert wind's kinetic energy into electricity.

• Wind energy is the heat generated by the Earth's core used for heating buildings.

• Wind energy is derived from solar panels that convert sunlight into electricity.

• Wind energy is the energy produced by burning fossil fuels to create electricity.

What are fossil fuels?

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

• Fossil fuels are renewable energy sources from plants.

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

• Fossil fuels are synthetic materials created in laboratories.

Explain the concept of geothermal energy.

• Geothermal energy is the heat from the Earth's interior used for electricity generation and direct heating.

• Geothermal energy is the process of burning fossil fuels for heat.

• Geothermal energy is the energy produced by wind turbines.

• Geothermal energy is derived from solar power.

What is biomass energy?

• Energy generated from nuclear reactions

• Energy derived from fossil fuels

• Biomass energy is energy produced from organic materials.

• Energy produced from solar panels

How does hydroelectric power generate electricity?

• Geothermal energy uses steam from underground to power generators.

• Electricity is generated by solar panels absorbing sunlight.

• Wind turbines convert heat from the earth into electricity.

• Hydroelectric power generates electricity by flowing water turning turbines connected to generators.

What are the advantages of using renewable energy?

• Limited job opportunities

• Higher greenhouse gas emissions

• Increased reliance on fossil fuels

• The advantages of using renewable energy include reduced environmental impact, sustainability, energy independence, job creation, and potential cost savings.

Why is it important to reduce our reliance on non-renewable energy sources?

• To maintain current energy consumption levels

• To support economic growth without limits

• To increase fossil fuel production

• It is important to reduce reliance on non-renewable energy sources to combat climate change and promote sustainability.
