In the future, secondary energy will be the best choice to food production market. The modern food production system is essentially a success of changing fossil fuels into food. So, raising energy prices are almost higher food costs and even shortage for fossil fuels energy. If one day, one kind of discovered secondary man-made renew used energy can supply to any restaurants or homes to be used to cook at the cheap price, then the profit is very high for this kind of food production energy. Thus, future food production secondary energy consumption market is large and because the primary energy inputs for agriculture are higher than the energy outputs of the food. However, future secondary man-made renew used energy for food production system is only one part of whole energy consumer in food industry. The food production is related to whole food consumption market which includes: household cooking energy market, agriculture or vegetable, rice, fruit etc. foods farming machines energy market, food manufacturing factories market, food machine package market, transportation food delivery market, supermarket or fruit/food sale stores market. They must need any energy inputs to achieve the food production or food transportation or warehouse / stores electricity supply or cooking energy needs. Hence, these food suppliers relate to any whole food factory manufacturers, food retailers, food wholesalers, farmers and home/restaurant cookers, all of them must need to use energy to carry on their food producing or food cooking or food transportation activities every day in overall food industry. Thus, it seems that undiscovered any second energy demand will be increased, when the primary energy supply number is decreasing. Also, when people can accept to use secondary energy to replace primary energy to be used for any cooking, transporting food, manufacturing food, food retail stores or warehouse food delivery energy need activities. Then, the secondary energy price will be fall down to attract many food energy consumers.Nowadays, the food industry energy may includes primary nature resource gas energy or electricity energy for house house families or restaurants cooking needs, food delivering lorry drivers driving needs usually. If future second man made renew used energy is invented successful popular to be used, e.g. hydrogen, electric recharged battery energy for electric vehicles or restaurant/home families cooking needs or food factories machine maufacturing energy needs. Then, the seconday energy will have possible to replace primary energy to be food industry energy market.Wiley, composition services graphics indicated that global primary energy consumption had been increasing 30 billion tons from 1830 year to 510 billion tons in 2010 year as well as global population size had been increasing from 70 billion 1830 yeat to 510 billion in 2010 year. Thus, it seems that global primary energy consumption will be needed largely after 2010 year. If future global nature resource primary energy is explored full number and it had not enough energy number to supply global human to use. Then, it will being many people feel uncomfortable and inconvenient, e.g. Some countries won't have enough energy to supply transportion tools to be driven, some homes and restaurants won't have enough energy to supply to cook to eat or to provide restaurant clients to eat etc. daily activies, due to human's much activities which are needs energy supply. Thus, it seems that global primary energy comsumption will be needed largely after 2010 year.
