Energy Efficiency | Save Energy Save Environment

Energy Efficiency – the subject everyone knows about but most of us don’t know what to do about it. Everybody wants to reduce their energy consumption and pay fewer electricity bills but most of us don’t know how to do it.

Well, today we are going to talk about what can be done to reduce your energy consumption.

Need for Energy Efficiency

So before talking about what to do for energy efficiency, let’s talk about WHY Energy Efficiency?

Energy efficiency means delivering the same (or more) services for less energy. When we use less energy, the less energy we need to generate at power plants, which reduces greenhouse gas emissions and improves the quality of our air. Energy efficiency helps the economy, too, by saving consumers and businesses millions of dollars in energy costs. Energy efficient solutions can reduce the energy bill for many homeowners and businesses by 20 to 30 %.

How to achieve Energy Efficiency – 

There are many different ways to reduce your household’s energy use, ranging from simple behavioural adjustments to extensive home improvements. The two major motives for conserving energy are to save on utility bills and protect the environment.

Here are some ways in which you can save energy & electricity in your house – 

  1. Adjust your day-to-day behaviours

To reduce energy consumption in your home, you do not necessarily need to go out and purchase energy-efficient products. Energy conservation can be as simple as turning off lights or appliances when you do not need them. 

  1. Replace your light bulbs

Traditional incandescent light bulbs consume an excessive amount of electricity and must be replaced more often than their energy efficient alternatives. Halogen incandescent bulbs, compact fluorescent lights (CFLs), and light-emitting diode bulbs (LEDs) use anywhere from 25-80% less electricity and last three to 25 times longer than traditional bulbs.

3. Purchase energy efficient appliances

On average, appliances are responsible for roughly 13% of your total household energy use. When purchasing an appliance, you should pay attention to two numbers: the initial purchase price and the annual operating cost. Although energy efficient appliances usually have higher purchase prices, their operating costs are 9-25% lower than conventional models.

When purchasing an energy efficient appliance, you should look for appliances with the ENERGY STAR label

4. Upgrade your HVAC system

An HVAC system is composed of heating, ventilation, and air conditioning equipment. Heating alone is responsible for more than 40% of home energy use.

Upgrades to the component of an HVAC system – ventilation – can improve your energy efficiency. A ventilation system is composed of a network of ducts, which distributes hot and cold air throughout your home. If these ducts are not properly sealed or insulated, the resulting energy waste can add thousands of rupees to your annual heating and cooling expenses. Proper insulation and maintenance on your ventilation system can reduce your heating and cooling expenses by up to 20%.

5. Insulate your home

Insulation plays a key role in lowering your utility bills through retaining heat during the winter and keeping heat out of your home during the summer. The level of insulation you should install depends on the area of your house. Your attic, walls, floors, basement, and crawlspace are the five main areas where you should consider adding insulation.

Conclusion – Energy conservation is important and beneficial as you can save money, save the environment. Take needful measures today only so that our future can also enjoy something which we are exploiting.

Lighting Sensors | The ultimate way for Energy Saving

Whenever we talk about energy saving we always talk about changing our daily habits, and go for energy efficient appliances. But in this modern era of technology where we have more than just bulbs and lights, then why only stick to the old traditional ways. It’s time that we should expand our vision and look for some other alternative which can give us more efficient output.

Lighting Sensors

The ultimate solution for using light only when needed is – Lighting sensors. Lighting sensors help you everyday by detecting and reacting to different levels of light in appliances, switches and machines. 

The light sensor is a passive device that convert this “light energy” whether visible or in the infra-red parts of the spectrum into an electrical signal output. Light sensors are more commonly known as “Photoelectric Devices” or “Photo Sensors” because the convert light energy (photons) into electricity (electrons).

Motion Sensitive Light Switches

One such product which has caught our attention and gained a lot of popularity over the past few years is motion sensor light switches. Motion sensor light switches turns on when they sense someone in the room and are switched off after a certain amount of inactivity. Motion sensors reduce electricity consumption by eliminating the possibility that the lights will accidentally be left on.

You see them more and more in corporate and public spaces, because they are convenient for employees and shut off after continued inactivity, significantly reducing energy expenses.

In order to detect the presence of a human being inside a room properly, the motion sensor can take advantage of several types of technologies – 

Pyroelectric Sensor – It measures the infrared radiation, and since everything emits a certain level of IR radiation, it is quite easy to detect major fluctuations emitted when a person passes by. The disadvantage is that the sensor will detect only significant movements and only in direct line of sight.

Ultrasonic Technology Sensor – This sensor uses the ultrasonic technology in order to detect smaller changes into the environment so the light doesn’t turn off when you’re reading a book or typing on the computer keyboard. To accomplish it, the sensor sends a small pulse into the room, which returns and allows the device to detect any changes. The disadvantage is that it can be prone to false detection and it draws more power.

Motion sensor light switches reduces energy consumption by 35-45 percent, and can go up to as high as 75 percent. 

Conclusion – 

Changing the light switches is a minor project, but one that can be incredibly convenient – not having to worry about turning off the lights when you are gone, especially in places that are frequently used, eliminates a common habit that many wish they could get a hold of.
