What is energy transfer?

• The process of creating energy.

• Conversion of energy from one form to another.

• Movement of energy from one object or system to another.

• The storage of energy in an object or system.

What is energy conservation?

• The practice of using energy wastefully and without regard for the environment.

• The process of generating more energy to meet increasing demand.

• The act of conserving natural resources other than energy.

• The practice of reducing energy consumption and using energy efficiently to minimize waste and environmental impact.

Why is energy conservation important?

• To reduce demand for energy, save money, and reduce environmental impact.

• To ignore energy usage, lose money, and increase environmental impact.

• To promote energy consumption, spend money, and increase environmental impact.

• To increase demand for energy, waste money, and increase environmental impact.

What are renewable energy sources?

• Renewable energy sources are sources of energy that are only available during certain times of the year.

• Renewable energy sources are sources of energy that are harmful to the environment.

• Renewable energy sources are sources of energy that are expensive and inefficient.

• Renewable energy sources are sources of energy that can be replenished naturally and are not depleted when used.

Name one renewable energy source.

• Solar energy

• Hydroelectric power

• Geothermal energy

• Wind energy

What are non-renewable energy sources?

• Non-renewable energy sources are energy sources that cannot be replenished or regenerated in a short period of time.

• Non-renewable energy sources are energy sources that are environmentally friendly.

• Non-renewable energy sources are energy sources that have an unlimited supply.

• Non-renewable energy sources are energy sources that can be replenished easily.

Give an example of a non-renewable energy source.

• Solar power

• Fossil fuels

• Wind energy

• Hydropower

How can we conserve energy in our daily lives?

• By leaving lights and appliances on all the time

• By turning off lights and appliances when not in use, using energy-efficient light bulbs, insulating our homes, using natural light and ventilation whenever possible, and reducing our reliance on fossil fuels by using renewable energy sources.

• By using energy-inefficient light bulbs

• By keeping our homes poorly insulated

What are the advantages of using renewable energy sources?

• Renewable energy sources have several advantages, including sustainability, reduced greenhouse gas emissions, energy independence, and job creation.

• Renewable energy sources require a lot of land and space.

• Renewable energy sources are unreliable and inconsistent.

• Renewable energy sources are expensive and not cost-effective.
