13 Facts About Primary energy
1.
2.
One consequence of this counting method is that the contribution of wind and solar energy is under reported compared to fossil energy sources, and there is hence an international debate on how to count primary energy from wind and solar.

3.
Primary energy is used in energy statistics in the compilation of energy balances, as well as in the field of energetics.
| FactSnippet No. 1,641,951 |
4.
In energetics, a primary energy source refers to the energy forms required by the energy sector to generate the supply of energy carriers used by human society.
| FactSnippet No. 1,641,952 |
5.
Secondary Primary energy is a carrier of Primary energy, such as electricity.
| FactSnippet No. 1,641,953 |
6.
Total primary energy supply is the sum of production and imports, plus or minus stock changes, minus exports and international bunker storage.
| FactSnippet No. 1,641,954 |
7.
Primary energy sources are transformed in energy conversion processes to more convenient forms of energy that can directly be used by society, such as electrical energy, refined fuels, or synthetic fuels such as hydrogen fuel.
| FactSnippet No. 1,641,955 |
8.
Electricity is one of the most common energy carriers, being transformed from various primary energy sources such as coal, oil, natural gas, and wind.
| FactSnippet No. 1,641,956 |
9.
For example, while wind turbines do not capture all of the wind's Primary energy, they have a high conversion efficiency and generate very little waste heat since wind Primary energy is low entropy.
| FactSnippet No. 1,641,957 |
10.
Site Primary energy is the term used in North America for the amount of end-use Primary energy of all forms consumed at a specified location.
| FactSnippet No. 1,641,958 |
11.
Site Primary energy is measured at the campus, building, or sub-building level and is the basis for Primary energy charges on utility bills.
| FactSnippet No. 1,641,959 |
12.
Source energy, in contrast, is the term used in North America for the amount of primary energy consumed in order to provide a facility's site energy.
| FactSnippet No. 1,641,960 |
13.
Either site or source Primary energy can be an appropriate metric when comparing or analyzing Primary energy use of different facilities.
