Earthing

marine

The electric connection of equipment to the main body of the earth to ensure that it is at earth potential. On board the ship, the connection...

Earthing (grounding) system

energy

An earthing system connects specific parts of an electric power system with the ground, typically the Earth's conductive surface, for safety and functional purposes.

Earth's atmosphere

energy

The atmosphere of Earth is the layer of gases, commonly known as air, retained by Earth's gravity, surrounding the planet Earthand forming its planetary atmosphere.

Earth's crust

energy

Earth's crust is a thin shell on the outside of Earth, accounting for less than 1% of Earth's volume.

Earth's energy budget

energy

Earth's energy budget accounts for the balance between the energy that Earth receives from the Sun, and the energy the Earth radiates back into outer space after having been distributed throughout the five components of Earth's climate system.

Earth's energy imbalance

energy

If the incoming energy flux is not equal to the outgoing energy flux, net heat is added to or lost by the planet (if the incoming flux is larger or smaller than the outgoing respectively).

Earth's internal heat budget

energy

The flow of heat from Earth's interior to the surface comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.

Earth's mantle

energy

Earth's mantle is a layer of silicate rock between the crust and the outer core.

Eastern Interconnection

energy

The Eastern Interconnection is one of the two major alternating current (AC) wide area synchronous power grids in the continental U.S. power transmission grid.

EC directive on marine equipment (European Union Marine Equipment Directive)

marine

The directive of European Commission about marine equipment for which international conventions require the approval of the national administrations as well as mandatory carriage on board.

ECDIS

marine

see electronic chart display and information system.

Eco-efficiency

energy

Applied to goods and services that satisfy our needs and bring quality of life and reduction in environmental impacts. It is based on the concept of producing more goods while reducing the resources required, especially those resources that harm the environment.

Ecological crisis

energy

An ecological crisis occurs when changes to the environment of a species or population destabilizes its continued survival.

Ecological design

energy

Ecological design or ecodesign is an approach to designing products and services with special consideration for the environmental impacts of the product during its whole lifecycle.

Ecological effects

energy

In British waters, the cost of removing all platform rig structures entirely was estimated in 2013 at £30 billion.

Economic dispatch

energy

The goal of economic dispatch is to minimize total operating costs in an area by determining how the real power output of each generating unit will meet a given load.

Economic geology

energy

Economic geology is concerned with earth materials that can be used for economic and/or industrial purposes.

Economic pillar

energy

Part of the three sustainability pillars, the pillar that focuses on profitability through good practices and governance.

Economical benefits

energy

The benefit of providing a service or making improvements to a service or system.
