What is Green/Renewable Energy?

• Energy that is only derived from solar power.

• Energy that is derived from sources that do not deplete natural resources or harm the environment, such as solar, wind, and hydro power.

• Energy that comes exclusively from fossil fuels.

• Energy that is produced by nuclear reactors.

What are the benefits of Green Energy?

• It increases greenhouse gas emissions.

• It provides a more expensive alternative to traditional energy sources.

• It provides clean, sustainable alternatives to traditional fossil fuel-based energy sources, reducing greenhouse gas emissions.

• It depletes natural resources faster than traditional energy sources.

What is energy efficiency?

• The use of more energy to perform tasks

• The use of less energy to perform the same task or produce the same result

• The use of renewable energy sources only

• The increase of energy consumption over time

Which of the following is an example of energy efficiency?

• Using more energy to heat homes

• Using less energy to cool and heat buildings

• Increasing energy use in electronics

• Manufacturing goods with high energy consumption

What is one of the effects of reduced energy usage on the environment?

• Increased carbon dioxide emissions

• Higher energy costs

• Reduced carbon footprint

• Increased air pollution

What does geothermal energy utilize to generate electricity and provide heating and cooling solutions?

• The movement of ocean currents, waves, and tides

• The Earth's natural heat

• Organic materials like wood, crops, and agricultural wastes

• Solar radiation

What is biomass energy primarily converted from?

• Ocean currents and tides

• Wind power

• Organic materials such as wood, crops, and agricultural wastes

• The Earth's magnetic field

What is the main advantage of using LED lighting over incandescent bulbs?

• Higher energy consumption

• Shorter lifespan

• More heat emission

• Greater energy efficiency

What role does insulation play in energy efficiency for buildings?

• Increases the need for heating and cooling

• Reduces the building's carbon footprint by minimizing energy loss

• Has no effect on energy consumption

• Decreases the building's durability
