What Is Energy Efficiency?

Energy-efficiency
The term “energy efficiency” often emerges when alternative power sources are discussed. This applies to electronics, appliances, cooling and heating equipment and so much more. Unfortunately, this phrase is misused in ways which only confuse its actual meaning.
 
Energy efficiency isn’t the same as conserving energy. Efficiency relates to the specific ways by which power is produced and consumed.

Efficiency Simplified

 
An energy-efficient device gets the most out of a certain amount of fuel or electricity. The formula to determine efficiency is output divided by input.
 
For example, a car that travels 210 miles on six gallons of gas receives a fuel economy rating of 35 miles per gallon (mpg).
 
Avoiding the trip is “conservation”. Taking a shorter route to get to the same place is “efficiency”. Basically, energy efficiency enables you to get the same results with less sunlight, fuel or electricity.

Energy Efficiency Rating

Many appliances, electronics, some building products, and many other modern amenities all have a rating which reveals how efficient they are.
Renewable-energyA solar panel, for example, is more efficient if it produces extra power from the same amount of sunlight when compared to another type of solar panel
It could, therefore, receive a higher efficiency rating.
 
This rating will differ from one manufacturer to another.
It’s always a good idea to look for the Energy Star Rating if you want to ensure you’re getting the most efficient product.

Global Energy Crisis

Energy efficiency is on top of our global conservation list. Currently, we are striving to find the quickest and least costly way of addressing our planet’s energy security.
 
The world continues to face environmental and economic challenges, and limited energy sources such coal and gas continue to be exploited as demand increases, regardless of the effect it has on the environment.
 
However, there still remains an abundance of untapt natural and renewable resources. Tapping into the Earth’s renewable energy is the only answer to the mass destruction caused by the endless over-consumption and exploitation of natural resources. 

Renewable Energy Sources

The sun is only one renewable energy resource that every country possesses in abundance. Yet the possibilities that solar power can provide is only in its relative infancy – with massive strides taken in the last few decades alone.
 
The same can be said for hydroelectricity, wind power, and other forms of renewable energy as well.
 
It’s important that we apply energy efficiency at home first, in our daily lives. Green living always starts at home. This will ensure that we serve the needs of the present without compromising future generations and their energy needs.

Power of the Future

The energy crisis is a broad and complex topic. Most people don’t feel connected to its reality unless there is a power failure for a few hours or even a line at the gas station.
 
However, as energy efficient policies and other government solar panel incentives have makes an impact on the global energy market, renewable energy has finally started playing a key part to address the ongoing energy crisis.
 
Energy efficiency is key to ensuring a safe, reliable, affordable and sustainable energy system for the future.
