Energy balance sheet; supply, transformation and consumption
This table shows the supply, transformation and the consumption of energy in a balance sheet. Energy is released - among other things - during the combustion of for example natural gas, petroleum, hard coal and biofuels. Energy can also be obtained from electricity or heat, or extracted from natural resources, e.g. wind or solar energy.
