What is energy change? For television energy change power case. Firstly, electrical energy changes to television power to be used by television itself, then it changes to light power, next it changes to light power. How to choose fuel form to use? Due to energy can change to different form of powers to supply different form of power advantages to supply to human to use, so it is possible that we can also invent any secondary man made renew used energy to change different form powers to supply us to use, e.g. nuclear energy changes to light or sound or heat form of powers; electrical charge batteries changes to light or sound or heat form powers to satisfy our daily life needs. For primary natural resource fuel energy example, different fuel has different feature, e.g. easy to burn, safe to use, gives out a lot of energy, inexpensive, produces little air pollution, easy to transport and store. How can we use in different channels, such as heating food, hot pat, driving vehicles. For example, although coal is not expensive to cause electricity energy for past transportation tool, e.g. traditional coal energy train or our daily home cooking, but it has negative influence to environment air pollution. Hence, we ought to follow the primary natural resource energy's feature to decide how to apply what aspects of our life needs. For example, if the country's people hope to reduce pollution when who use any kind of energy, e.g. US, Europe energy markets. The energy entrepreneur ought concentrate on manufacturing the kind of energy which can reduce environment pollution to be the least level to supply the country people to use, e.g. electric charge battery supplies to these countries' drivers to drive their vehicles on the roads, wind energy or water energy to manufacture electricity power supply to reduce air or water pollution; or if the country people hope to buy the inexpensive energy to use, even the energy's quality and performance is worse, e.g. China, India, Hong Kong markets. The energy entrepreneur ought concentrate on manufacturing the lowest cost and enough supply of natural resource to manufacture the kind of energy to sell cheap price to these countries to use, e.g. China, Africa can accept to use e.g. gas, coal, fuel energy to use to compare developed countries people, e.g. UK, US; or if the countries people who hope to use energy which can easy to transport and store, e.g. light coal. The energy entrepreneur can choose to concentrate on manufacturing much coal to supply to the countries people to use, e.g. China, Arica Thus, to choose to manufacture which kinds of energy supply to the countries market people to use, the energy entrepreneur how decides to manufacture which kind of energy, it depends on which kinds of fuel advantages of the countries people most concerning.Hence, when human feel energy shortage will come soon, energy users will reduce to use more energy to avoid energy shortage occurs in possible. It means that energy consumption number will be influenced to reduced or energy consumption buyers will reduce much expenditure to buy energy products for driving use or home use or office, warehouse working places to use. Energy needs or demand will reduce, due to environment pollution problem and energy shortage problem can influence global energy consumers' useful behaviors to be reduced in the future.
