Conservation or Efficiency Definition


Efficiency- noun
: the ability to do something or produce something without wasting materials, time, or energy : the quality or degree of being efficient ( technical )


Conservation- noun
: the protection of animals, plants, and natural resources
: the careful use of natural resources (such as trees, oil, etc.) to prevent them from being lost or wasted
: the things that are done to keep works of art or things of historical importance in good condition.


Energy efficiency is “using less energy to provide the same service.”
Energy conservation is “reducing or going without a service to save energy.”



CONSERVATION- JIM MACINNES   In this seven-minute video Jim MacInnes explains the use of both, conservation and efficiency on energy saving projects at Crystal Mountain. It’s not just the big things, it’s the small things as well…  Watch video or read transcript>>


Who makes the world’s most efficient residential solar panels? The panels listed here have earned the right to be considered when homeowners are looking for a system to provide the best savings over the years. Remember that solar technology is moving quickly and striving for higher efficiency with each new panel created, so manufacturers regularly discontinue solar panels and release new, more efficient panels to take their place. This chart will help get you started  understanding available solar panel efficiencies from a variety of manufacturers:…Who is on the list>>


The Worldwide Adoption of Energy Free Lighting
A decade or more ago, experts were examining America’s consumption of world resources and in particular energy. The study revealed that despite making up barely 5% of the world’s population, America was consuming 20% of its energy. The question asked by this experts was not how to curb American excess, but what if China, with its 1.5 billion inhabitants consumed at the same rate as the world’s number 1 economy.

Today we are steadily getting closer to that point, but in terms of lighting at least, there is a solution. In 2015, India launched the Domestic Efficient Lighting Programme or DELP which was designed to distribute 770 million LED light bulbs to houses across the country in order to reduce energy usage. Are LEDs the solution to global energy consumption? This article investigates.


If we want to understand how the world is consuming energy and relate it to lighting, we need to look at electricity usage. The Indian gambit, 770 million LED bulbs is aimed at cutting its consumption. Across the world, we use 19,320,360,620 MWh of electricity a  year. This works out at 313 MWh per person per year. The top users of electricity by total usage across the world are: see the top users>>


The Difference Between Energy Conservation And Energy Efficiency
There’s a fascinating post on the Sustainable Buildings Centre blog that outlines how the world energy community has tended to stop using “energy conservation” and to use “energy efficiency” instead…Read more>>
