The summer electricity consumption measurementsand comparison with winter

At first…

…we would like to explain two questions from the winter measurements.

In winter…

• …we found a house with a very low consumption.

• However, in summer the consumption was the highest there!!!

• And, they had changed the electrometer in the meantime...

• So, we do not know if there was a mistake or if the consumption changed so much…

The school…

• …had also a very, very low consumption.

• First we were searching for another electrometer in the school – there was none.

• Our investigation went on...

• …and we found out that to get the right consumption the number on the electrometer must be multiplied by 40!

In summer we got these data

Winter consumption of the school

9920 KWh

Summer consumption of the school

6320 KWh

Less consumption in summer. Why?

• In summer lights are switched on for shorter time than in winter.

• In summer people go more often out and do not sit at computer so much.

• In summer people cook less. • Some houses use electric heating in winter.• However, air condition is not common in our

country in summer yet.

What to do now

• We have to find ways how to manage energy - it means how to reduce energy consumption.

• It will be the main task of this project year!

• See you in Portugal and in France!

Thank you!
