Energy Sources and Environmental Impact

The video discusses energy resources, highlighting the difference between renewable and non-renewable sources. It explains how renewable resources like sunlight and wind are sustainable, while non-renewable resources such as fossil fuels and nuclear energy are finite and have environmental impacts. The video emphasizes the importance of integrating renewable energy into our consumption to meet growing demands.

What is the first law of thermodynamics related to energy?

• Energy can be transformed but not created or destroyed.

• Energy is always increasing.

• Energy can be created and destroyed.

• Energy is always decreasing.

Which of the following is a characteristic of renewable energy resources?

• They are only used in industrial applications.

• They are always in the form of fossil fuels.

• They are quickly restored by natural processes.

• They are finite and cannot be replenished.

Which of the following is NOT a renewable energy source?

• Sunlight

• Wind

• Coal

• Geothermal heat

What are fossil fuels primarily formed from?

• Ancient organisms

• Minerals and rocks

• Ocean water

• Volcanic ash

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

• Solar power

• Biomass

• Natural gas

• Wind energy

What is the main environmental concern associated with burning coal?

• It cools the surrounding environment.

• It releases carbon dioxide and other pollutants.

• It absorbs greenhouse gases.

• It releases oxygen into the atmosphere.

Which fossil fuel is known for being the cleanest burning?

• Natural gas

• Petroleum

• Peat

• Coal

What is a significant advantage of nuclear energy?

• It produces a lot of greenhouse gases.

• It requires a large amount of fuel.

• It produces minimal greenhouse gas emissions.

• It is easily renewable.

What is a major drawback of nuclear energy?

• It is not energy-dense.

• It is a renewable resource.

• It produces dangerous radioactive waste.

• It is very cheap to produce.

Why is it important to integrate renewable resources into our energy mix?

• They are only available in certain regions.

• They can be restored by natural processes and reduce environmental impact.

• They are finite and will run out soon.

• They are more expensive than non-renewable resources.
