Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process. The presence on an item of a recycling code, a chasing arrows logo, or a resin code , is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
In this case, speed reference will be 104% and actual speed will be 100%. For every 1% change in the turbine speed reference, the power output of the turbine will change by 25% of rated for a unit with a 4% droop setting. Droop is therefore expressed as the percentage change in (design) speed required for 100% governor action.

A chemical oxygen generator is a device that releases oxygen via a chemical reaction. The oxygen source is usually an inorganic superoxide, [1] chlorate, or perchlorate. Ozonides are a promising group of oxygen sources, as well. The generators are usually ignited by a firing pin, and the chemical reaction is usually exothermic, making the ...

An application programming interface ( API) is a way for two or more computer programs or components to communicate with each other. It is a type of software interface, offering a service to other pieces of software. [1] A document or standard that describes how to build or use such a connection or interface is called an API specification.
High income countries such as the United States and Canada use 100 times as much energy per capita as some of the least developed countries in Africa. [35] Energy efficiency—using less energy to deliver the same goods or services, or delivering comparable services with less goods—is a cornerstone of many sustainable energy strategies.

Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. Using renewable energy technologies helps with climate change mitigation, energy security, and also has some economic benefits. [1] Commonly used renewable energy types include solar energy, wind power, hydropower, bioenergy ...
