All you should know about energy

A Comprehensive Review of Energy

Posted by

This full Energy Review tells you more on everything you should know about Energy and its properties as it is important to humans just like the air we breathe; in today’s world, we need energy in all facets of life, in our homes, offices, workplace, and other areas so its benefits to mankind can’t be over-emphasized. This is a comprehensive piece to give great highlights about energy and all that it has got to offer.

Below are all facts about energy and all its details. The coverage includes its types, forms, sources, means of transferring, the importance, efficiency, benefits, how to save it, and more.

What is Energy?

things you should know about energy and its attributes

Energy can be defined as the power that is drawn from the usage of chemical and physical resources to provide heat and light to working machines and tools. It is a quantitative property that is transferred to an object in order to heat the object and perform work.

Energy exists in nuclear, chemical, thermal, potential, electrical, and kinetic forms. If you want to know the units for Energy, just have it in mind that the electrical unit for power is the watt and this is expressed in joules.

What Are the Types?

The following below are the types of energy:

Chemical Energy: This is the energy that both molecules and atoms stored in the bonds of chemical compounds. It discharges in a chemical reaction. By burning them, chemical energy can be used in fuels such as coal and wood.

Mechanical Energy: This is the energy that a substance or system has because of its motion. Machines are typical examples of objects that use mechanical energy to do work.

Electrical Energy: This is the energy that is carried by moving electrons in an electric conductor. Electrical energy is one of the most common forms of energy. Other forms of energy can be converted to electrical energy. Like power plants change chemical energy stored in fuel like coal into electricity via different changes in its form.

Nuclear Energy: This is the type of energy that can found in each atom. Nuclear energy can be produced either by fission i.e. splitting of atoms or fusion which is combining atoms through the fission process is the most used method.

Thermal Energy: This is the energy a system or substance has in relation to its temperature. This is the energy of vibrating or moving. For example, solar radiation can be used to cook food.

What Are the Forms?

The major forms of energy are two namely: kinetic and potential energy

Kinetic Energy: This is the kind of energy in moving objects or mass such as electrical energy, mechanical energy etc

Potential Energy:  This form of energy stores potential that can be put for future use such as chemical and nuclear energy.

What Are the Sources?

There approximately 10 sources of energy which are:

Solar Energy: This kind of energy is harvested via the sun with the use of collector panels.

Wind Energy:  This is the use of large turbines to grab available wind as power then turbine will turn a generator to produce electricity.

Geothermal Energy:  This energy that is gotten from beneath the earth. It is always eco-friendly light

Hydrogen Energy: This energy is gotten from the use of water

Tidal Energy: This is energy gotten from the rise and fall of tides to change kinetic energy of incoming and outgoing tides into electrical energy.

Wave Energy: This energy is gotten from the waves that are release in the oceans

Hydroelectric Energy:  This is energy gotten from the dam to produce electricity

Biomass Energy: This energy is gotten from organic material

Nuclear Power:  This energy is from the creation of a specific nuclear reaction.

Fossil fuels: This is gotten from oil, coal and natural gas.

How to Transfer

Energy can be transferred in 3 ways. There are:

Conduction: This is because heat is thermal and it is solid so can be transferred via conduction

Convection: Another way is through convection, this is used for both fluids and liquids transfer

Radiation: This is done through sound waves and light waves

What is Energy Efficiency?

Energy efficiency means the goal to reduce the amount of energy that is required to supply services and products like insulating a home enables a building to make use of less cooling and heating energy to achieve and maintain a comfortable temperature.

What Are the Benefits of Energy Efficiency?

There are various benefits derived from energy efficiency, they include:

  • Increased efficiency can reduce greenhouse gas emissions
  • It improves energy and lower individual utility bills
  • It helps provide long-term benefits by reducing overall electricity demand
  • It helps to diversify utility resource portfolios.

What Are the Importances?

Energy is important because it is a great source for generation of electricity; it is needed in businesses, schools, factories and homes. It is what is use to power our gadgets and devices such as computers, TVs, air conditioners and washing machines and in same vein is used to run cars, motorcycles, planes, buses and trains.

What is the Cleanest Energy?

The cleanest energy is the wind energy, harnessing power from the wind is said to be the best source of electricity powering output.

What is Energy Conservation?

Energy conservation is the effort that one puts in place to reduce power consumption by using less of a power supply. This can be said to be one of the factors of eco-sufficiency used in rising power consumption at home, officer, place of business and so on.

How is Energy Measured?

Energy can be measured in kilowatts and watts which is a name gotten from James Watt. A watt is equivalent to one ampere.

How to Save

Energy can be save using the following procedures:

  • Use smart power strips
  • Adjust the light activities at home
  • Purchase energy-efficient appliances
  • Install a smart thermostat or programmer

What Consumes the Most Energy?

  • Water heater
  • Washer and dryer
  • Refrigerators
  • Electric oven
  • Dishwater
  • Television
  • AC (Air Condition)

How to Reduce Energy Consumption

  • Shut down appliances when not in use
  • Choose to use mostly LED bulbs
  • Turn off your light when not in use
  • Do away with vampire power


We are much more dependent on energy especially for electricity than we were fifty years ago, because a lot of modern technologies are heavily dependent on the use of energy to power their equipment and tools and as such energy is one thing that can be overlooked. This comprehensive review has brought to your doorstep all you needed to know about energy and all its attributes.
