Energy Efficient Appliances
Using energy efficient appliances in the home is one way of reducing
electricity usage and, therefore, carbon emissions.
It helps contribute to maintaining a low-energy
home and preserve the environment. Energy efficient appliances
are generally labelled, following similar standards in each country.
In most countries it is mandatory to display an 'Energy' label on
Energy Efficient Labelling
Under EU regulations the following electrical goods must carry
an energy efficient label:
- Washing Machines
- Tumble Dryers
- Electric Ovens
- Digital Televisions
- Lamps, Light bulbs, Light fittings.
Understanding Energy Labels
Energy labels rate the efficiency of an appliance according to
an acceptable standard. For example, the EU energy label ranges
from 'A' to 'G', with 'A' being the most efficient and 'G' being
the least efficient.
The least enery efficient household appliances are washing machines
These will often carry additional categories, such as 'A+' and
A+ models are between 25% more efficient than
A++ models are 60% more efficient than standard
Energy labels also include other useful information that helps purchasers
rate them according to their energy consumption goals.
This may include:
- Energy consumption - in kWh (kilo watt hours
- units of energy used per hour). The less kW per hour that are
being consumed, the more efficient the appliance will be, thus
reducing damage to the environment and saving money.
- Performance Gauge - from 'A' to 'G' for washing
machines, tumble dryers and dishwashers . A is the highest performance,
G the lowest.
- Water Consumption - Lower water consumption
will be cost effective and will have positive effects for the
- Noise level - measured in decibels [dB]
- Energy Efficiency Recommended - awarded by
government supported 'Energy Efficient Trusts' and only applied
to the most efficient products.
Energy Efficient Products
Least Efficient Products - this is where you can
make some great energy savings by reading a few labels and looking
for appliances with more advanced, energy efficient technoloyg.
Savings of up to 80% can be achieved in this category of appliances.
- Refrigerators - up to 80% energy saving
- Washing Machines - up to 30% energy saving
- Tumble Dryers
Using the most efficient appliances across the board will have
a massive impact on the amount of energy you consume. Fortunately,
there is now strong pressure on both manufacturers and retailers
to provide energy efficient appliances.
Even small electrical appliances can have an impact, using energy
efficient Compact Fluorescent bulbs can save up to 4 times more
energy than a standard bulb.
So every time you are buying a new appliance, of any size, ask
the vendor to compare the energy efficiency for you. It may make
your shopping a little longer, but it saves you money in the longer
term, and contributes to saving the environment.
Solar cookers use sunlight for cooking, drying and pasteurization;
thereby offsetting electricity or fuel costs whilst simultaneously
improving air quality by reducing smoke.
Box Cooker - The simplest class of solar cooker,
consisting of an insulated container with a transparent lid. These
cookers can be used effectively with partially overcast skies and
will typically reach temperatures of 50-100 °C. These appliances
are economic, simple and perform well.
Concentrating solar cookers - use reflectors to
concentrate light on a cooking container. Reflectors may be either
flat plate, disc and parabolic trough type. These cookers cook faster
and at higher temperatures (up to 315 °C); but do require direct
light and need to "track" the sun.
