The laundry is an essential part of any households — it also happens to be an easy place to start when trying to go green. Knowing how to manage your laundry properly can help you significantly reduce electricity consumption, decrease greenhouse contribution and save on costs down the line.
When buying a new washer…
A washing machine is a long-term investment. It is going to be used every week and can last more than a decade. So, it is vital that you make the right decision and get one that leads to the most efficiency while suiting your needs. Here are some tips on how to choose the washer that will suit you most.
1. Choose a front loader
In general, front loaders are more energy efficient and consumes less resources than a top loader due to their design. They use less water, less detergent and less electricity for hot washes.
Although the initial cost is more, front loaders make up for it in the long run due to their efficiency.
2. Choose washing machines with higher star ratings
When choosing a new washing machine, the easiest place to look first is the energy efficiency rating. It’s simple. More stars mean a more energy efficient machine. In fact, each star adds about 25% more energy efficiency. This means the cost to run it greatly reduces the more stars it has.
A 1 star machine consumes 378kWh of electricity per year for warm washes. The washer will cost $104 to run that year.
A 3.5 star machine of same size uses 146kWh of electricity per year. The more energy efficient washer costs will only cost $40 to run. 
If you want to find the running cost of a particular model, multiply the Kwh number on the label with your electricity tariff at home.
3. Choose the right connections
It’s better to use cold washes, but if you are using warm washes, choose a machine with both hot and cold water connection. This allows you to use hot water from the home hot water system to heat up the water, which is usually more efficient than using the heating element in the washer itself.
It also allows you to connect the solar thermal hot water system for warm washes, if you have one at home.
4. Choose the right features
Manufacturers have introduced many new technology and functions into their washing machines. It can be confusing to know which one will benefit you, so we narrowed the list down on key things to look for.
Cold wash function: Cold washes can save more than 80% on energy consumption, since most of the energy used actually goes into heating up the water.
Load sensing technology: Those with load sensing technology can adjust the amount of water to your load size and lets you save on water consumption.
Eco mode: Many machines also come with an eco-friendly mode which consumes less energy and water.
Delay or programmable timer: try to choose machines with timers, so you can start washing when your electricity tariff is cheaper. You can also use it to soak clothes before washing them. More on this later.
