A concentrated solar energy plant utilising 760 parabolic troughs producing 134 GWh per year.

The newton-metre is a unit of torque (also called moment) in the SI system.

A nickel metal hydride battery is a type of rechargeable battery.

A type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes

A rechargeable battery having nickel oxide-hydroxide positive plates and iron negative plates, with an electrolyte of potassium hydroxide. It is often used in backup situations where it can be continuously charged and can last for more than 20 years

An inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

NIMBY, an acronym for the phrase "not in my back yard" is a characterization of opposition by residents to proposed developments in their local area, as well as support for strict land use regulations.

A synthetic rubber that is a copolymer of butadiene and acrylonitrile. It has good resistance to petroleum-based substances and is often used in seals.

Chemical tankers, gas carriers and reefer ships need clean, dry nitrogen for inerting, purging and cargo padding.

A waste gas from the combustion of fuels in engines due to the reaction between nitrogen and oxygen.

Nitric oxide (NO) and Nitrogen dioxide (NO2) are usually grouped together as NOx emissions.

Not to be confused with nitric oxide (NO) or nitrogen dioxide (NO2), nitrous oxide (N2O) a potent greenhouse gas.

The noble gases (historically also the inert gases) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.

A point that is at rest in a vibrating body.

A new mandatory code for the protection of seafarers against noise on board.

Nominal power refers to the maximum output of a generating plant in normal operating conditions.

The nominal power is the nameplate capacity of photovoltaic devices, such as solar cells, modules and systems, and is determined by measuring the electric current and voltage in a circuit, while varying the resistance under precisely defined conditions.

Relates to power that is cannot be ramped up or ramped down quickly to meet load fluctuations.

Fuels not obtained from non renewable sources.

A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.
