Question

Which energy sector (Residential+Commerical, Transportation, Industrial Sector) has the greatest need for energy conservation and why? Which energy sector is most likely to achieve significant energy conservation and Why?

Answer 1

Energy conservation

Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently or by reducing the amount of service used.

Transportation sector has the greatest need for energy conservation.

in present world the transportation is becoming very popular amoung each country, The transportation sector includes many modes, from personal vehicles and large trucks to public transportation (buses, trains) to airplanes, freight trains, ships and barges, and pipelines.

The major types of energy used for transportation in the world are

Petroleum products—products made from crude oil and from natural gas processing, including gasoline, distillate fuels (mostly diesel fuel), jet fuel, residual fuel oil, and propane

Biofuels—ethanol and biodiesel

Natural gas

Electricity (produced from many different energy sources)

Petroleum even exists far below the deepest wells that are developed to extract it. However, petroleum, like coal and natural gas, is a non-renewable source of energy if we cannot conserve it one day it will be exehausted.

Other energy given has some alternatives but transportation energy is mainly depend on non renewable resources.

Industrial sector is most likely to achieve significant energy conservation

Industrial sector

The industrial sector of the economy is one that make finished products which can then be utilized viz. construction and manufacturing industry. Industrial sector is also known as secondary sector.

Industrial sector or secondary sector is one of the 3 sectors that make up a country's economy.

The total energy consumed by industrial sector is very much high compare to the the residential and commercial in a particular geographical area, they use generally the electricity for running machines which is developed by generally the non renewable form.

The industrial sector uses more delivered energy than any other end-use sector, consuming about 54% of the world’s total delivered energy. The industrial sector can be categorized by three distinct industry types:

1) energy-intensive manufacturing,

2) nonenergy-intensive manufacturing, and nonmanufacturing,

3) The mix and intensity of fuels consumed.

in the industrial sector vary across regions and countries, depending on the level and mix of economic activity and on technological development. Energy is used in the industrial sector for a wide range of purposes, such as process and assembly, steam and cogeneration, process heating and cooling, and lighting, heating, and air conditioning for buildings. Industrial sector energy consumption also includes basic chemical feedstocks. Natural gas feedstocks are used to produce agricultural chemicals. Natural gas liquids (NGL) and petroleum products (such as naphtha) are both used for the manufacture of organic chemicals and plastics.

This is the reason to conserve the industrial energy by conserving the renewable energy for future use.
