Question

• Be able to identify the forms of kinetic vs. potential energy, and to list some forms of each. • Be able to state the Law of Conservation of Energy. Also, what is the definition of energy efficiency? • What is the difference between renewable and nonrenewable energy? Be able to identify each major source of energy as renewable or nonrenewable. • What is the distribution of energy consumption in the U.S. by energy sector? Is most of the energy that we consume renewable or nonrenewable? Is electricity a primary or secondary source of energy? What IS a secondary source of

Answer 1

Answers and Explanation:

Forms of Kinetic energy

• Translational kinetic energy

• Rotational kinetic energy
• Vibrational kinetic energy

Forms of Potential energy

• Gravitational potential energy

• Electrostatic potential energy

• Elastic potential energy

• chemical potential energy

Energy efficiency is a measure of the amount of energy conserved in a process. It is the ratio of the output energy to the input energy.

Differences between renewable and non renewable energy

• Renewable energy can replenish themselves by recycling and replacement while non-renewable energy cannot
• Renewable energy are continuously available while non renewable energy are exhausted
• Renewable energy has low carbon emission and hence environment friendly while non renewable energy has high carbon emission and not environmental friendly

Sources of renewable energy

Solar energy.

Wind energy.

Hydro energy.

Tidal energy.

Geothermal energy.

Biomass energy.

Sources of non-renewable energy

Coal

Petroleum

Natural gas

Distribution of energy consumption in the US by energy sector

Petroleum = 36.2 %

Natural gas = 28%

Coal = 13.9%

Renewable energy = 11.0%

Nuclear electric power = 8.4%

Most of the energy consumed by the United States is non-renewable

Electricity is a secondary source of energy. It is derived from the conversion of primary sources

A secondary source of energy is a derivative from the transformation of primary sources of energy
