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.

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>>


LED Lights Will Save the World
Energy efficiency has become a very hot topic socially and politically in recent decades. As the world population grows, the consumption of energy grows. Countries with large populations and advanced economies are the highest consumers of energy. China, The United States of America, and Russia lead the world in energy consumption. The rate at which energy consumption is growing is scary, but have we found a solution?

SOLAR- ARTICLES pheobe   India recently introduced a new program using LED lighting to test a new lighting efficiency. The results of the campaign may provide helpful insight for the rest of the world as we attempt to battle the growing energy crisis. The program didn’t rely on any fancy technology that requires super advanced economies; it focused on lightbulbs and improving a simple technology that even less advance countries use every day. While the results are limited and do not provide a full picture answer to the crisis, they show us that progress can be made. Learn more>>



“Energy conservation” and “energy efficiency” are often used interchangeably, but there are some differences. At the most basic level, energy conservation means using less energy and is usually a behavioral change, like turning your lights off or setting your thermostat lower. Energy efficiency, however, means using energy more effectively, and is often a technological change. Energy efficiency measures the difference between how much energy is used to provide the same level of comfort, performance or convenience by the same type of product, building or vehicle.

A combination of both energy conservation and energy efficiency measures yields an ideal solution…Read more>>



Energy efficiency is “using less energy to provide the same service”.  There are other definitions, but this is a good operational one.

The best way to understand this idea is through examples:

– When you replace a single pane window in your house with an energy-efficient one, the new window preventsRead more>>
– When you replace an appliance, such as a refrigerator or clothes washer, or office equipment, such as a computer orRead more>>

Energy efficiency is not energy conservation.
Energy conservation is reducing or going without a service to save energy.

Why Is Energy Efficiency The Most Abundant, Cheapest Way To Reduce Greenhouse Gas (GHG) Emissions?
Anywhere energy is used, there are opportunities to increase efficiency. In most cases, energy efficiency measures will pay for themselves over time in the form of lower energy bills.

How quickly they pay back their investment depends on a lot of factors, such as…Read more>>


Global Energy Efficiency Market ‘An Invisible Powerhouse’ Worth At Least USD 310 Billion Per Year
Energy efficiency is a way of managing and restraining the growth in energy consumption. Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input. For example,…Read more>>


Conservation Vs Efficiency: Sweaters Are Not The Answer
…If we want to reduce fossil fuel use, become energy independent, and cut carbon emissions—the first thing we have to do is improve the efficiency of the way we use energy in the first place. To reduce your miles driven by 20 percent in a vehicle that gets nine miles to the gallon is progress, but it’s missing the point. It’s also somewhat futile to set your air conditioning thermostat up two degrees in a building with single-pane windows and poor insulation…Read more>>


The Basics: Energy Efficiency 101
…Energy efficiency means doing more with less—so we maintain (or exceed) performance while saving both energy and money. An efficient air conditioner will keep you cool using less electricity and a car with better fuel economy will require fewer fill-ups while still getting you where you need to go. Energy efficiency can help…Read more>>


What Is The Difference Between Energy Conservation And Energy Efficiency?
With energy efficiency, you don’t have to sacrifice comfort to save energy. Energy conservation involves a change in behavior to save energy (turning off the lights, powering down computers and electronic equipment at night, lowering the thermostat in winter and raising it in summer). Energy efficiency means physical upgrades like replacing worn out weather stripping, repairing leaking ductwork, adding insulation, replacing inefficient lighting and appliances, etc…Read more>>
