Thermal Insulation in the World and EU

1973 was an important year in terms of energy policies of countries. Economic gridlock resulting from the "Oil Crisis" which arose when the countries exporting oil limited the oil supply and then increased the oil prices unexpectedly urged all world countries to seek new ways regarding energy. On one hand, countries sought alternative energy resources and on the other hand they tried to take immediate measures in terms of energy efficiency. An upward trend in oil prices during the years following the crisis has made the measures regarding the energy efficiency an essential part of the economy policies of countries.

Growing population, industrialization and new technologies bring increasing energy requirements. An increase in the energy amount consumed worldwide can be seen clearly from the graph below. When statistical data are analyzed; it can be seen that the amount of the energy consumed worldwide increased by 18.7% during the period of 10 years between 1993 and 2003. In 2002, energy consumption increased by 2.9% across the world and reached the level of 9741.1 Million TEP in 2003.

According to the data of 2003, USA consumes 23.6% of the total energy consumption across the world. People's Republic of China, Russian Federation and Japan follows USA with rates of 12.1%, 6.9% and 5.2% respectively. Contribution of EU to total energy consumption is 15.4%.

Resources that the energy consumed is obtained can be collected under two titles. The first one consists of fossil fuels such as coil, oil and natural gas and nuclear energy resources. Energy resources in this group are limited and named as "non-renewable energy resources". The other group consists of "renewable energy resources" such as solar, wind, water and geothermal energy resources.

A large part of the energy consumed worldwide is obtained from non-renewable energy resources. According to data obtained in 2003 regarding world energy consumption, share of nuclear energy is 6%; total share of oil, natural gas and coil is approximately 82%. On the other hand, only the share of hydraulic energy which is included in renewable energy resources is relatively high. Share of hydraulic energy within the world energy production is approximately 6%. Share of other renewable energy resources is about 1%.
