Efficient motors - Electric motors that are more energy efficient than conventional models currently used in China.

Efficient processing - Processes that are energy-efficient, low-polluting, eco-friendly and leave behind little or no solid waste.

Effluent - Wastewater (treated or untreated) that comes out of sewage treatment facilities and/or industrial facilities.

Electric 2 wheelers (E2W) - Bikes and scooters equipped with a rechargeable battery and an electric motor used for propulsion.

Electric auto vehicle (EAV) charging systems - Systems that allow for plug-in electric vehicles to be charged using power from the grid.

Electric locomotives - Locomotives powered by an electric engine which uses an electricity source, such as an overhead line, third rail or an on-board electricity storage device, rather than fossil fuels to meet its energy requirements.

Electrical/electronic waste (e-waste) - Discarded, obsolete, broken or surplus computers, entertainment electronic devices, mobile phones, televisions, refrigerators and electronic items, whether sold, donated or discarded by their original owners.

Embodied energy - Total energy used in the manufacturing of product. An accounting method that computes the sum total of the energy necessary for the entire life cycle of a product.

Emission standards - Requirements that set specific limits to the amount of pollutants that can be released into the environment, which generally include nitrogen oxides, sulfur oxides, particulate matter, etc.

Energy intensity of GDP - Average amount of energy consumed to produce a unit of GDP.

Engineering, procurement, construction (EPC) - Project contract that includes engineering, procurement and construction.

Enhanced coal bed methane (CBM) recovery - Process of recovering additional coal bed methane from hydrocarbon-rich rocks.

Enhanced oil recovery (EOR) - Solutions that increase the amount of extractable crude oil from an oil field, such as: gas injection, chemical injection, ultrasonic stimulation, microbial injection or thermal recovery.

Environmental management system (EMS) and IT systems - Comprehensive, systematic, documented management of an organization’s environmental programs that rely on IT solutions for effective operation.

Ethanol 10 (E10) - Vehicle fuel comprised of 10% ethanol blend with gasoline that has become a standard in China. Blend can be used in standard internal combustion engines without need for modifications.

Extraction solutions - Solutions that help locate, access and extract water from underground sources.
