Inert gas Inert gas An inert gas/noble gas is a gas which does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances, and were historically referred to as the inert gases. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. These undesirable chemical reactions are often oxidation and hydrolysis reactions with the oxygen and moisture in air. The term "inert gas" is context-dependent because several of the noble gases can be made to react under certain conditions. Purified argon and nitrogen gases are most commonly used as
Phase-out of incandescent light bulbs to delay new energy efficiency standards for light bulbs until 1 January 2014, when it will become illegal to import inefficient incandescent lighting across the country. In December 2011, Ontario Energy Minister [Chris Bentley] confirmed that Ontario is scrapping the five-year-old plan "to avoid confusing consumers". The Energy Star program, in which Natural Resources Canada is a partner, in March 2008 established rules for labelling lamps that meet a set of standards for efficiency, starting time, life expectancy, colour, and consistency of performance. The intent of the program is to reduce consumer concerns about efficient light bulbs due to variable
