Energy Conservation and Efficiency
While conservation is a definite requirement and has its virtues, it will not result in the performance of products at optimal levels — this is only achieved by opting for energy efficient products, which can save us resources and money too.
Efficient products are those that do the same or in cases even more than what we require while using lesser energy. An efficient air conditioner for example, will use less electricity but still keep you as cool as a conventional air conditioner. That’s why we need to address and understand energy efficiency in order to cut back on our energy bills.
So what does energy efficiency mean for a homeowner? Many efficient products are available in the market today — most of us would have heard of appliances that are “star” rated or of “LED” lights being more energy efficient than conventional bulbs.
Let’s get down to the basics to dig a little deeper in to this subject — energy is measured in watts and kilowatts — and it is measured over time as kilowatt–hour.
As a thumb rule one KWh is equivalent to turning on one conventional 100W bulb for 10 hours.
Let us now consider a more ‘efficient’ fixture such as an LED bulb. In order to give out the same amount of light as a 100W bulb we will need to use a 16W LED bulb. Calculated over the same 10-hour period, an LED bulb will use only 0.16kWh of energy over the conventional bulb.
This efficiency saves a whole lot of energy.
