Did you know about...?


Energy is the ability to do work or make changes. It causes things to happen around us like eating, studying and playing, there are plenty ways of energy The sun produces heat and light energy which helps the plants to grow and at night we turn on the lamps to illuminate our homes and this uses electrical energy and when you drive your car it moves by fuel which is type of stored energy, even the food we eat contains energy and we use this energy to work and play.


Energy Efficiency?

Reducing the energy consumption for a given service or level of activity in order to produce the same level of end-use service. For example, using compact fluorescent light (CFL) it reduces the amount of electricity needed for lighting.



Electricity is type of energy, it generates during moving of million electrons around each other to create energy, it lights up our homes, cooks our food, powers our computers and TVs, electric companies make the electricity and convert it to our homes


Renewable Energy?

Energy produced from renewable resources such as solar, wind and geothermal energy.


Solar Energy?

it means using the energy of sunlight to provide electricity, to heat water and to heat or cool homes. It can be divided into direct and indirect categories, most of energy sources on earth are form of indirect solar energy (coal, oil…etc), all the energy in wood and foodstuffs also comes from the sun, movement of the wind which cause waves at sea.

 solar energy

Wind Energy?

energy from the wind caused by moving air masses, the movement is caused by temperature and pressure difference in atmosphere, it can be converted to mechanical energy for driving pumps mills and electric power generators.

 wind energy

Biomass Energy?

a type of renewable energy generated by burning wood, agricultural waste, fuel crops, sewage sludge, manure or methane from landfills.

 biomass energy


the energy we make with moving water, this energy is used to produce electricity.


Geothermal Energy?

heat under the ground used to heat water and make steam to turn generator turbines and make electricity.
