As a laundry expert with extensive knowledge in the field, I'm delighted to provide an in-depth answer to your question regarding water consumption for a load of laundry.

Laundry is a daily necessity, and with the ever-growing concern for water conservation, understanding the amount of water used in washing machines is crucial. The amount of water required for a single load of laundry can vary significantly based on several factors, including the type of washing machine, the size of the load, and the selected wash cycle.

Older top-loading machines, as mentioned by Energy Star, are known to be less efficient and typically use around 40 gallons of water to wash a full load of clothes. This is a considerable amount, especially when compared to newer models. The inefficiency is primarily due to the way these machines are designed, with water being used to agitate the clothes rather than using the force of gravity to move them through the water.

In contrast, newer standard models have been designed with water conservation in mind. These models can use as little as 27 gallons of water for a full load. The reduction in water usage is achieved through various technological advancements, such as more efficient pumps and improved drum designs that allow clothes to be cleaned with less water.

However, for those who are truly committed to water efficiency, the best option would be to invest in an Energy-Star certified washing machine. These machines are designed to be even more water-efficient, using around 14 gallons of water per wash. The Energy-Star certification ensures that the machine not only conserves water but also saves energy, making it an environmentally friendly choice.

It's also important to consider the size of the load you're washing. Overloading a washing machine can reduce its efficiency and lead to the use of more water than necessary. On the other hand, underloading can also be wasteful, as the machine will use the same amount of water regardless of the load size. It's best to wash full loads whenever possible to maximize efficiency.

The type of wash cycle selected can also impact water usage. Heavier cycles with more rinses will naturally use more water, while quick or delicate cycles will use less. Choosing the appropriate cycle for your laundry needs can help conserve water.

In addition to the machine and cycle type, the water level setting can affect water usage. Most modern washing machines have an automatic water level adjustment, but if yours does not, it's essential to set the water level correctly to avoid wasting water.

Lastly, it's worth noting that the water used in a washing machine is not just a one-time use. Many people are now opting to collect the water from their final rinse cycle to use for other purposes such as watering plants or cleaning, further reducing the overall water footprint of their laundry routine.

In conclusion, the amount of water it takes to do a load of laundry can range from around 14 gallons for an Energy-Star certified machine to 40 gallons for an older top-loading model. By choosing the right machine, load size, and wash cycle, and by being mindful of water usage, you can significantly reduce the water footprint of your laundry routine.
