What You Need To Know About Energy
What do you know about energy?
If electricity production wastes between 40 and 65% of the primary energy source, why is it used?
- Producing electricity is a way to store energy.
- Electricity production results in no harmful emissions.
- Electricity is a versatile energy carrier.
