Primary sources of energy are raw sources of energy like coal, crude oil, natural gas, wood, water, etc. which has not yet been converted into anything. This primary energy is then converted to secondary energy, or a more usable form of energy, e.g. electricity, diesel, petrol, etc. There are losses during this conversion process. <\/p>\n\n\n\n Secondary energy is then transmitted to consumers to be used. During this transmission, there are transmission and distribution losses<\/p>\n\n\n\n When the consumers receive this energy, in the form of electricity, gas, petrol, etc., it is called final energy. Unfortunately, many countries around the world stop collecting energy usage data at this stage. But what comes after this stage is extremely important to build a complete energy flow diagram and to understand the energy efficiency of a country or the tremendous amount of energy wastage taking place within its borders.<\/p>\n\n\n\n When the consumers receive what is called final energy, that energy is not the final product. The consumers don’t want energy. They actually want a service, like light, cooling, heating, food, entertainment, productivity, mobility, etc. They use the energy to fuel the appliances, machines, cars, etc. that will provide them that service. So there are also conversion losses at this stage based on the energy efficiency of the appliances, vehicles or machines used. And also based on the behaviour of the consumer.<\/p>\n\n\n\n When you track the energy flow of every primary energy consumed inside a country, you can build or compile an energy flow diagram for your country, or even for your office, home, factory or organization. As soon as you compile an energy flow diagram, you can now see all the sources of wastage and energy losses for your country or organization. And once you can see the energy wastage, you can finally do something about it.<\/p>\n\n\n\n![\"energy](\"https:\/\/savejoules.com\/blog\/wp-content\/uploads\/2019\/05\/energy_flow_explanation-1024x460.gif\")
