ENERGY STAR certified dishwashers use up to 20% less water and 10% less energy than non-certified models. For apartment dwellers and small household owners, choosing an ENERGY STAR model isn't just good for the planet—it's smart economics. Over the lifetime of your dishwasher, you could save hundreds of dollars on utility bills while reducing your environmental footprint.
This guide explains what ENERGY STAR certification means, how much you can save, and which portable dishwashers offer the best combination of efficiency and performance.
ENERGY STAR is a U.S. Environmental Protection Agency (EPA) voluntary labeling program that identifies and promotes energy-efficient products. To earn ENERGY STAR certification, appliances must meet strict energy and water efficiency guidelines set by the EPA.
Protect the environment and help consumers save money by promoting the use of energy-efficient products and practices.
Since 1992, ENERGY STAR has helped save more than 5 trillion kilowatt-hours of electricity and reduce carbon emissions by over 2.5 million metric tons.
The EPA independently tests and verifies that appliances meet strict efficiency standards. You know exactly what you're getting.
The distinctive blue ENERGY STAR label makes it easy to spot efficient models when shopping.
Reduced water and energy use means lower carbon emissions and less strain on natural resources.
While ENERGY STAR models may cost slightly more upfront, utility savings quickly offset the difference.
ENERGY STAR standards for dishwashers are updated periodically to drive continuous efficiency improvements. Here's what the current standards require:
📌 Note: ENERGY STAR standards become more stringent over time. Older certified models may not meet current requirements, so look for the latest certification year when shopping.
| Category | Non-ENERGY STAR | ENERGY STAR | Annual Savings |
|---|---|---|---|
| Water Usage | 6.0 gal/cycle | 5.0 gal/cycle | ~$12-20 |
| Electricity | ~0.80 kWh/cycle | ~0.72 kWh/cycle | ~$8-15 |
| Heating Water | Higher usage | Lower usage | ~$10-25 |
| Total Annual | ~$30-60/year |
Annual Savings
$30-60
10-Year Total
$300-600
ENERGY STAR dishwashers typically cost $25-$75 more than non-certified models. This premium is usually recouped in just 6-12 months through utility savings—making ENERGY STAR a smart investment.
💰 Example Calculation:
Using less electricity means less dependence on fossil fuels. One ENERGY STAR dishwasher saves about 1 ton of CO2 over 10 years.
Saves approximately 1,300 gallons of water annually—critical in drought-prone regions and essential for sustainability.
Less energy consumption means less mining and drilling for fossil fuels, preserving natural resources for future generations.
When multiplied across millions of households, ENERGY STAR products collectively make a significant difference in combating climate change.
Reduced water and electricity consumption directly lowers your monthly utility bills year after year.
ENERGY STAR appliances are attractive to homebuyers, potentially increasing your home's resale value.
Many states and utility companies offer rebates and tax credits for purchasing ENERGY STAR appliances (check local programs).
ENERGY STAR models often feature newer technologies like soil sensors and optimized spray patterns that improve performance.

Even with an ENERGY STAR certified dishwasher, how you use it makes a difference. Here are tips to maximize efficiency:
Always run your dishwasher with a full load. Running it half-full wastes water and energy. If you don't have enough dishes, wait until you do.
Most ENERGY STAR models work well with cold water. Modern detergents are formulated for cold water efficiency. You save significantly on heating costs.
Modern dishwashers don't need pre-rinsing. Just scrape off large food particles. Pre-rinsing wastes 7-27 gallons of water per load.
If your ENERGY STAR model has soil sensors, use them! They automatically adjust water and energy use based on how dirty dishes are.
For lightly soiled dishes, use the eco or quick cycle. These use less water and energy while still cleaning effectively.
Use air dry mode instead of heated drying. Simply prop the door open after the cycle ends. Saves significant energy with no performance loss.
Pair your ENERGY STAR dishwasher with eco-friendly detergents like Seventh Generation. They work great with efficient cycles and are better for the environment.
Clean spray arms and filters monthly. A well-maintained dishwasher runs more efficiently. Mineral buildup reduces efficiency significantly.
💡 Pro Tip: Following these efficiency tips can save an additional 10-15% beyond the ENERGY STAR baseline, potentially saving you $40-80 annually!
Choosing an ENERGY STAR certified dishwasher is one of the smartest decisions you can make for your wallet and the environment. With modest premium costs that are quickly recouped through utility savings, ENERGY STAR models are a no-brainer investment.
