Resources & Energy

Our everyday electricity and heat come from energy resources. Sunlight, wind, and water are renewable because we can reuse them, while coal, oil, and gas are non-renewable and get used up. Burning fossil fuels also releases carbon dioxide that warms the planet. Pick the sun, wind, water, or fossil fuels here to see how each powers our lives.

Where Does Energy Come From?

⚡ Energy Resources

①Daily electricity and heat come from energy resources

②Sunlight, wind, water, coal, oil are all energy resources

③Energy resources are used to generate electricity

④Different resources have different environmental impacts

Renewable vs Non-Renewable

Batt Energy Classification

Renewable vs Non-Renewable

💡 Why Is Renewable Energy Important?

①Fossil fuels have limited reserves

②Burning them releases CO₂ and causes global warming

③Renewable energy is clean and unlimited

④We must increase renewable energy for the future

Energy Conservation

🌍 Saving Energy in Daily Life

①Turn off unused lights

②Set AC to a reasonable temperature

③Walk for short distances

④Save water

⑤Recycle to save resources

Summary

Renewable Energy

Sun + Wind + Water + Geothermal = Unlimited

Clean and reusable

Non-Renewable Energy

Coal + Oil + Gas = Limited

Used up once and pollutes the environment

🎯 Key Points

①Energy resources: things used to generate electricity

②Renewable: sun, wind, water (unlimited, clean)

③Non-Renewable: coal, oil, gas (limited, polluting)

④Burning fossil fuels → CO₂ → global warming

⑤Conserve and shift to renewables

Examples and Unit Test

Example 1

Between solar energy and coal, which is a renewable energy that can be reused?

Renewable energy, like sunlight, wind, and water, can be used again and again.

Solar energy is renewable because the Sun keeps shining, while coal is non-renewable because it is gone once burned.

▸ Solar energy (renewable)

Sun, wind, and water are renewable; coal and oil are non-renewable.

Example 2

What problems arise from continuing to use fossil fuels?

Fossil fuels like coal and oil have limited reserves and keep decreasing.

Burning them releases carbon dioxide, which causes global warming.

▸ They are limited, and burning them pollutes the environment with carbon dioxide

Fossil fuels are finite and release carbon dioxide that harms the environment.

Unit-test style

Which statement about resources and energy is correct?

①Coal is a renewable energy that can be reused

②Solar energy is a renewable energy that can be reused

③Burning fossil fuels releases no carbon dioxide

④Oil can be used forever

⑤Wind energy is a non-renewable energy

▸ ② Solar energy is a renewable energy that can be reused

Solar energy is renewable because the Sun keeps shining.

Coal and oil are limited, non-renewable fuels (① and ④), burning them releases carbon dioxide (③), and wind is renewable (⑤).
