Energy definition

● Definition: Energy is the capacity of a physical system to perform work.

Types of energy● Mechanical energy● Electrical● Electromagnetic energy● Sound energy● Chemical energy● Nuclear energy● Thermal or calorific energy

Mechanical energy

● Kinetic energy● Potential energy

Kinetic energy

● Energy that objects have when they're in motion

Potential energy

● Energy that objects have when they're moved from their stable position of equilibrium

Electrical energy

● Energy associated with an electrical current

Electromagnetic energy

● Transported by electromagnetic waves, such as radio, television or X-ray waves

Sound energy

● Associated with the sound waves that are transmitted through vibrations.

Chemical energy

● Stored in substances – it can be released or absorbed during chemical processes

Nuclear energy

● Contained the nuclei of atoms

Thermal or calorific energy● Comes from the vibration of particles in matter

Energy

● Renewable energy● Non-renewable energy

Renewable energy sources

● Hydraulic energy● Solar energy ● Wind energy● Marine energy● Geothermal energy● Biomass

Hydraulic energy

● Hydraulic energy is what is produced by the water wich stored in reservoirs and lakes at high altitude.

Solar energy

● Solar energy, radiant light and heat from the sun.

Wind energy

Wind energy is the energy from wind, that is, the kinetic energy generated by the effect of air currents, and is transformed into other use-ful forms for human activities.

Marine energy

● Marine energy refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences.

Geothermal energy● Geothermal energy is thermal energy

generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter.

Biomass● Biomass, as a renewable energy source, is

biological material from living, or recently living organisms. As an energy source, biomass can either be used directly, or converted into other energy products such as biofuel.

Non-renewable energy

● Nuclear energy● Coal● Petroleum● Natural gas

Nuclear energy

● Nuclear energy usually means the part of the energy of an atomic nucleus, which can be released by fusion or fission or radioactive decay

Coal

● Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.

Petroleum

● Petroleum or crude oil is a naturally occurring, flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface.

Natural gas

● Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane

Wind turbine creates water from thin air● Eole Water have invented a new type of eolic

turbine that produce drinking water from humid air.

● A turbine can produce, filter and purify the water up to 1,000 litres of drinking water every day.

● This is a solution clean and sustainable way to provide water to isolated rural communities, in Africa and South America as well as remote islands in Asia but nowadays is a expensive solution.
