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

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 €

III. A new project for a new start
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 €

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 !
