An intergovernmental organization or international governmental organization (IGO) is an organization composed primarily of sovereign states (referred to as member states), or of other intergovernmental organizations.

Intergovernmental organizations are often called international organizations, although that term may also include international nongovernmental organization such as international nonprofit organizations or multinational corporations.

Sustainable energy is energy that is consumed at insignificant rates compared to its supply and with manageable collateral effects, especially environmental effects.

Another common definition of sustainable energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their needs.

The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture.

Sustainability science is the study of sustainable development and environmental science.

A nation (from Latin: natio, "people, tribe, kin, genus, class, flock") is a large group or collective of people with common characteristics attributed to them — including language, traditions, mores (customs), habitus (habits), and ethnicity.

By comparison, a nation is more impersonal, abstract, and overtly political than an ethnic group.

It is a cultural-political community that has become conscious of its autonomy, unity, and particular interests.

A transition economy or transitional economy is an economy which is changing from a centrally planned economy to a market economy.

Transition economies undergo a set of structural transformations intended to develop market-based institutions.

These include economic liberalization, where prices are set by market forces rather than by a central planning organization.

In addition to this trade barriers are removed, there is a push to privatize state-owned enterprises and resources, state and collectively run enterprises are restructured as businesses, and a financial sector is created to facilitate macroeconomic stabilization and the movement of private capital.

The process has been applied in China, the former Soviet Union and Eastern bloc countries of Europe and some Third world countries, and detailed work has been undertaken on its economic and social effects.
