I. When energy flies away …
Today our energy comes mainly from petrol Petrol costs more and more Petrol is pollution
We must react !!!We must react !!!

I. When energy flies away …
• Main energy sinks in our buildings
Lights Machines Computers Heating during winter Cooling during summer Bad insulation of walls and roofs

I. When energy flies away …
• How to reduce the bill?
Change the employees customs
Change our machines
Change our sources of energy

II. Alternative energies
Solar energy
Solar power– provide electricity to light on the factory or power
on the motors
Solar thermal– Provide hot water

II. Alternative energies
Advantages and Disadvantages of Solar power
Pro– Unlimited and free
– Clean energy
– Usable everywhere in the world
– Government helps

II. Alternative energies
Advantages and Disadvantages of Solar power
Cons– Limited efficiency of the solar panel
– The cost of the installation
– Depend on the weather
– Not available anytime in the day
– Energy storage problems battery6 year lifetime

II. Alternative energies
Geothermal energy
High and middle energy– Temperature > 90°C
– Produce electricity
Low and ultralow energy– Temperature < 90°C
– Heating systems

II. Alternative energies
Advantages and Disadvantages of Geothermal
Pro– Economical power
– No stock needed
– Easy to maintain
– Ecological : save 60% of the heating bill
– Government helps

III. A new project for a new start
I. Swap the heating system by a geothermal power unit
• A lot of free space in
front of our firm
• Compacity of the
power unit
• Cost : 30.000 €

II. Produce electricity with some solar panels
• Typical production
of solar energy :
400 kW/year/m²
10 m² needed
• Lack : bought
• Surplus : sold
• Cost : 50.000 €

III.How does it work ?
• In summer :
as a cooling system

IV. Going even further….
Why not creating a common power unit ?• Reduction of the investments• Higher efficiency• Being a model for other firms• Improve our public image• Saving more money !
