Energy Demand

As the society increase with increase in time, the need for energy grows in a very significant manner. The energy would be used to power industry, run the economy, transportation, electricity generation and vital services. The demand of the energy continuously to grow and the demand are from these categories:

•                                  Residential/ Commercial

•                                  Transportation

•                                  Industrial

•                                  Power Generation

Residential/ Commercial

The evolution of energy is begins at home. From simple firewood burn to modern application of cooking, heating, cooling, cleaning, refrigerating and lot more uses energy. Until 2030 with increasing of population and society more home and business will need energy to power up activity but until that time the fuel that will be used is cleaner, more diverse and more efficient. Residential demand is seen to be the largest among these two sectors is expected to grow by more than 20% from 2005 to 2030. The energy demand includes energy used directly from home such as cooking, heating and also for electricity appliances such as lighting and air conditioning.

Transportation

Through 2030 the demand of the energy will be led by aviation, trucking, marine requirement and an increase number of personal vehicle in Asia. With the price hike of the fuel in world energy scenario,   ongoing improvement and development of fuel economy technology has been introduced to conventional internal- combustion vehicles. Personal vehicles are only one part of transportation picture. The demand of fuel in commercial transportation will grow about 30% in North America and Europe and more than 100% in Asia Pacific region.

Industrial

Through the expanding of economy, the demand for energy will also be increase. In industry the energy is used to produce cement, steel, chemicals, and other durable goods. These are the foundation of the economy that built today. The energy demand for this sector is expected to grow about 30% from 2005 to 2030. The growth is due to the increasing production of cement for construction, steel and also in general manufacturing. The growth will be also includes for the increasing production of chemical.

Power Generation

To fulfill the growth of demand for energy is one of the world biggest challenges. By shifting to other natural gas and cleaner sources for power generation offers an alternative to reduce the CO2 emission. Global electricity demand will increase by more than 80 % through 2030.The demand is due to residential/ commercial and industrial sector. Electric vehicle and other transportation application still remain limited.

With the increasing demand for energy, lots of option with current technology and situation will be take under consideration such as:

•                                  Remain to use traditional fuel (coal, petroleum, natural gas and etc)

•                                  Introducing of renewable energy

•                                  The use of nuclear energy to generate electric.

The option given above has pros and cons but which will be implemented?
