Non-Renewable and Renewable Energy Sources

The video tutorial discusses the importance of energy, distinguishing between renewable and non-renewable sources. Non-renewable energy, such as oil, gas, and coal, cannot be replaced once used and contributes to greenhouse gases. Nuclear energy, while non-renewable, does not emit CO2 but poses risks due to toxic waste. Renewable energy sources like solar, wind, and hydroelectric power are sustainable but face challenges like high costs and public opposition. The video also highlights that some resources, like trees, can be either renewable or non-renewable based on usage.

What is a key characteristic of non-renewable energy resources?

• They are always cheaper than renewable resources.

• They can be replenished quickly.

• They are always environmentally friendly.

• They cannot be replaced once used.

Which of the following is a non-renewable energy source?

• Solar power

• Wind power

• Coal

• Hydroelectric power

What is a major risk associated with nuclear power?

• It is inconsistent like wind power.

• It is very expensive to produce.

• Nuclear waste is highly toxic.

• It produces a lot of CO2.

Which of the following is NOT a renewable energy source?

• Wave

• Tidal

• Oil

• Geothermal

What is a common issue with wind power?

• It produces a lot of greenhouse gases.

• It can be inconsistent.

• It is very cheap to produce.

• It is always available.

How can trees be considered a renewable resource?

• By planting them in deserts.

• By replacing them after they are cut down.

• By not cutting them down at all.

• By using them only for fuel.

What is a potential downside of renewable energy sources like wind turbines?

• They are always consistent.

• They can ruin the landscape.

• They produce a lot of CO2.

• They are non-renewable.

Which energy source can be both renewable and non-renewable depending on its usage?

• Solar
