ENERGY SAVING

• The energy saving is the best alternative source

• But to save something it is necessary to know it

NON-RENEWABLE ENERGY

It is exhaustible and not unlimited. It needs a very long time to reform itself (some whole geologic era). Hurrier it runs out, bigger will be its exploitation.

Its burning produces harmful emissions to the environment.

NON-RENEWABLE ENERGY

The principal primary non-renewable sources are:

a) chemical energy stored in fossil fuels (petrol, etc.);

b) nuclear energy stored in radioactive materials

ENERGY PRODUCTION TABLE >

RENEWABLE ENERGY

It is inexhaustible and unlimited in nature.

It produces “clean” energy and it doesn’t produces pollutants for humans and the environments

RENEWABLE ENERGY

The principal primary renewable sources are:

a) solar energy; b) hydraulic energy; c) wind energy; d) wave energy; e) tidal energy; f) chemical energy from

organic substances (biomass);

g) geothermal energy.

ENERGY PRODUCTION TABLE>

ACCESS TO ENERGY TODAY

• The actual organization and distribution of energy give, to the earth inhabitants, the following accesses:– 50 % no access– 30 % insufficient access– 20 % easy access

ELECTRIC ENERGY

It is the energy produced by an electric central (with the use of a machine called “alternator”) using mechanical energy or heat.

SOME BASIC UNITS

• WATT: electrical power unit -1 kilowatt (kW) = 1000 Watt

• WATTHOUR: electrical energy unit – 1 kilowatt hour (kWh) = 1000 Watt hour

• LUMEN: symbol lm it is the unit of luminous flux

• LUX: symbol lx = lumen/m2 it is the unit of illumination

INCANDESCENT LAMPS

It produces the light by an incandescent filament of tungsten. The glass bulb of the lamp is filled with a gas mixture (inert gas and nitrogen) that make the filament does non burn.

COMPARISION TABLE LAMPS >

FLUORESCENT LAMPS

This lamp is filled with a gas (mercury vapor) that excited by electricity, emits radiations. These are changed in visible light by a layer of a fluorescent dust that is in the internal side of the glass tube.

COMPARISON TABLE LAMPS >

CARBON DIOXIDE (CO2) Symbol CO2 – The carbon

dioxide is a gas dangerous for humans produced during the burning. If we burn methane we put in the air 242 g of CO2 every 1 kWh of energy produced.

The carbon dioxide is fixed by the trees and through the phenomenon of “photosynthesis” is transformed into oxigen (symbol O) that is necessary for human life.

In 1 year a tree is able to transform about 2,5 Kg of CO2

GREENHOUSE EFFECT

The phenomenon “greehouse effect” guarantees on the Earth optimal values for the evolution of life. The Earth, infact, absorbs the sun’s rays and put them up in the form of heat. This happens because our planet is surrounded by an anvelope of gas (greenhouse gas) that trap the sun’s rays as the glass of a greenhouse. The increase, however, of the greenhouse gas carbon dioxide causes an increase of the greenhouse effect: greater it is the amount of CO2, greater will be the sun’s energy retained by the atmosphere, causing a rise in the global temperature on the Earth.

GREENHOUSE EFFECT• This phenomenon involves

a change of climate with the following consequences:

• a) Instability of artic ice; • b) ice melting; • c) rising of sea levels; • d) intensification of the

weather phenomenon; • e) advancement of the

desert areas; • f) reduction of water

resources; • g) effect on migration

flows.

THE ELECTRIC ENERGY SAVING• Buy household appliance belonging

to the classes A++, A+ and A:they guarantee a low power consumption. TABLE

• Use washing machines and dishwashers only with full load. Prefer washing programs at low temperature

• Put the fridge at 10 cm from the wall in the less hot area in the kitchen, away from the stove. Don’t introduce hot food inside: frost forms and consuption increase

• For lighting the home, choose fluorescent bubs: they consume up to 70% cheaper than traditional bulbs and they last up to 8 times higher TABLE

• After use, do not leave electrical equipment (TV, HI-FI, PC, etc.) in stand-by: if you turn off them, you save about 10% of energy. TABLE
