The Earth resources are quite limited in quantity
Many challenges to mankind in 21st century: development,
health, water, food, demography, education, energy
Energy…

Energy
is an abstract concept for different concrete manifestations
-cooking, heating
- lighting
- mechanical work: machines
-Industrial processing
- information processing
-transports
• In physics, energy (Ancient Greek: ἐνέργεια energeia "activity, operation"[1]) is a quantity that is
often understood as the ability a physical system has to produce changes on another physical
system.[2][3] The changes are produced when the energy is transferred from a system to another. A
system can transfer energy by means of three ways, namely: physical or thermodynamical work,
heat transfer, or mass transfer.
• Energy is a scalar physical quantity. In the International System of Units (SI), energy is measured in
joules, but in many fields other units, such as kilowatt-hours and kilocalories, are customary.
•
Energy is by nature of conservation: Energy may not be created nor destroyed.
• Any form of energy can be transformed into another form. When energy is in a form other than
thermal energy, it may be transformed with good or even perfect efficiency, to any other type of
energy.
•
With thermal energy, however, there are often limits to the efficiency of the conversion to other
forms of energy, as described by the second law of thermodynamics. Depending on circumstances,
some fraction of thermal energy exists in a form unavailable for further transformation; the
remainder may be used to produce any other type of energy, such as electricity.
Primary sources of energy
Fire from burning wood or oil
Animal force (horses, dogs, buffalos,…)
Water of rivers and tides (mills, …)
Wind (pumps, mills,…)
And other forms of renewable energies
5
Energy sources of 21st century
• Fossil fuels: coal, oil, natural gas
• Nuclear Energy
=> Primary Energy and Energy Storage Vectors
• Electricity: secondary form of energy as of modern energy type of high
quality, synonym of development.
• During 20 th century, there are great concerns for our green planet:
- natural resources are quite limited, especially in terms of energy
- mankind is destroying the earth environment in the process of his
development
• What is the future: towards a development with renewable resources?...
• And which new energy vectors will be adapted?

• Fossil Fuels are widely and directly used as
primary sources and serve as convenient
energy vector with low efficiency.

Joules, BTUs, Quads
A quad is a unit of energy equal to 1015 (a
short-scale quadrillion) BTU,[1] or 1.055 × 1018
joules (1.055 exajoules or EJ) in SI units.
The unit is used by the U.S. Department of
Energy in discussing world and national
energy budgets. The global primary energy
production in 2004 was 446 quad, equivalent
to 471 EJ. [2]
Some common types of an energy carrier
approximately equal 1 quad are:
8,007,000,000 Gallons (US) of gasoline
293,083,000,000 Kilowatt-hours (kWh)
36,000,000 Tonnes of coal
970,434,000,000 Cubic feet of natural gas
5,996,000,000 UK gallons of diesel oil
25,200,000 Tonnes of oil
252,000,000 tonnes of TNT or five times the
energy of the Tsar Bomba nuclear test.
