Energy and Climate Awareness

What is the principle of energy conversion?

• Energy is always lost during conversion.

• Energy can be created from nothing.

• Energy can only exist in one form at a time.

• Energy cannot be created or destroyed, only converted from one form to another.

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

• Hydropower

• Solar energy

• Wind energy

• Fossil fuels (coal, oil, natural gas)

What is the main cause of global warming?

• Ocean acidification

• Increased solar activity

• Deforestation of rainforests

• Increase in greenhouse gases, especially carbon dioxide.
