Renewable Energy

• Energy from sources that can be replenished, like solar, wind, and water.

• Energy derived from fossil fuels such as coal and oil.

• Energy that cannot be replaced once used, like nuclear energy.

• Energy generated from the combustion of organic materials.

Efficiency

• A measure of how much useful energy is converted in a system.

• The total energy input into a system.

• The speed at which energy is consumed.

• The amount of waste produced by a system.

Non-Renewable Energy

• Energy from sources that can be replenished, such as solar power.

• Energy from sources that cannot be replenished, such as fossil fuels.

• Energy derived from the sun and wind.

• Energy that is available in unlimited quantities.

Carbon Footprint

• The total amount of greenhouse gases produced by human activities.

• A measure of the distance traveled by carbon atoms in the atmosphere.

• The total weight of carbon in a person's diet.

Fossil Fuels

• Renewable energy sources like solar and wind.

• Non-renewable energy sources like coal, oil, and natural gas.

• Energy sources derived from nuclear reactions.

• Energy sources that are abundant and sustainable.

Work

• The energy transferred when a force is applied to an object causing it to move.

• The amount of energy stored in an object at rest.

• The force exerted on an object without causing movement.

• The total energy of an object in motion.

Power

• The rate at which energy is used or produced, measured in joules (J).

• The rate at which energy is used or produced, measured in watts (W).

• The total amount of energy consumed over time, measured in kilowatt-hours (kWh).

• The maximum energy output of a system, measured in horsepower (hp).
