GEKA SUSTAINABILITY - SUSTAINABILITY QUIZ

Do you know that …


...coal discovery has been a key lever
into the industrial era?

Sometimes perception and fact based information are not
aligned if we consider the life cycle of our energy sources. The source
of our electricity is a key element in our array of actions to limit the
climate change to 1.5°C.

Do you know
the 1st source of energy used
to produce electricity globally?

Choose your answer!

Coal represents the vast majority of electricity source in the world with a steady basis of 38%.

As you can read on the picture below, Electricity and Heat represent the main contributor to CO2 emission.

DID YOU KNOW THAT?

In term of CO2, coal represents the worst-case scenario in comparison to other type of energy used to create electricity. The following graph shows the content of CO2 per KwH of electricity produced (ADEME source) including the upstream part of the sector (from raw material extraction until electricity creation). 

In reality we must be careful never to run out of electricity. We use it daily and consider it a given.  However, we should be careful when comparing different electricity sources. 

If we consider a scenario with only renewable energy sources like solar panel, wind and water, we know, that they won’t be sufficient. Indeed, we may experience black out during peak demand and not have enough demand whilst they are available (very sunny in the summer during lunch time for exemple). These renewables sources are intermittent and not reliable because it is not possible to plan the consumption.

If we consider a second scenario with a mix of renewable energy sources and maneuverable sources like coal or gas power plant, the electricity available on the grid can fit the demand but the CO2 mix will be higher than having just renewable energy. 

Finally, if we consider a third scenario with a mix of renewable energy sources and maneuverable sources like nuclear power plant, the electricity available on the grid can fit the demand with a lower CO2 mix than with the coal or gas power station.

WHAT CAN YOU DO AS INDIVIDUAL?

See the answer!

At the individual level:

- The best energy is the one which is not used. Decrease by 1°C in cold temperature your inside temperature
and put a sweater. In summer time, put aircon on 26 °C will allow a decrease
of 40% of your aircon system consumption.

- At your place, insulate your home if possible to avoid energy waste.

- Select electricity which has a low carbon content and if possible renewable energy.
