The Dishwasher Energy Use Guide: Saving Money and the Planet
Today, we're diving into the world of dishwasher energy use and exploring how these essential kitchen appliances impact our wallets and the environment. Let's get started!
Dishwashers have become an indispensable part of modern kitchens, making our lives easier by tackling the tedious task of washing dishes. (Some people say they love washing by hand? Not sure we can relate.) These time-savers use a combination of hot water and detergent to blast away food residues and grime, leaving our plates and cutlery squeaky clean.
But is a dishwasher energy efficient? Water efficient? Good for your budget and the planet? Let’s get to the bottom of it:
How much energy do dishwashers use on average?
Energy consumption varies depending on the model and usage patterns, but on average, a standard dishwasher uses around 1,800-2,400 watts of electricity per cycle. According to the U.S. Department of Energy (DOE), the annual energy consumption of a dishwasher typically ranges from 120 to 300 kWh, or the carbon equivalent to driving 330 miles in an average gasoline-powered passenger vehicle.
What does that mean in dollars? As an example, a dishwasher consuming 1,800-2,400 watts per cycle costs about:
How long does the average dishwasher last?
The lifespan of a dishwasher largely depends on the quality of the appliance and how well it's maintained. On average, you can expect a dishwasher to last around 10-12 years. Regular cleaning, avoiding overloading, and ensuring proper maintenance can help extend its life.
How efficient are new dishwashers?
Good news! With advancements in technology and growing awareness of energy efficiency, newer dishwashers are far more energy-efficient than their older counterparts. Look for dishwashers with an ENERGY STAR® label, as they meet or exceed strict energy efficiency guidelines set by the EPA. These models can save you both energy and money in the long run, even more than washing dishes by hand! (Not that we needed another excuse to ditch that ritual.)
How much, you may be wondering? A new ENERGY STAR certified dishwasher uses less than half of the energy used when washing dishes by hand - and it saves more than 8,000 gallons of water each year versus washing dishes by hand! A standard-sized ENERGY STAR certified dishwasher costs about $35 per year to run and can save you an average 3,870 gallons of water over its lifetime. (Nearly the same amount of water as a 12x12 foot swimming pool!)
How much energy do dishwashers use when they’re running versus when they’re off?
While running a dishwasher consumes significant energy, it's essential to be mindful of the energy it uses even when it's off. (Though it’s far more minimal.) Many dishwashers have standby or "phantom" power consumption to power display panels and electronic features. If you’re concerned about phantom power and want to minimize this, consider unplugging the dishwasher when not in use if it’s not hardwired (look for an outlet under your sink) or use a smart plug to power it down in between cycles.
How often should you replace a dishwasher?
Knowing when to replace your dishwasher can be a bit tricky. If your current dishwasher is more than 10-12 years old and requires frequent repairs, it might be time to consider an upgrade. Newer models are not only more energy-efficient but also come with better features and enhanced cleaning capabilities.
Has the energy efficiency of dishwashers improved over the past 5-10 years?
Absolutely! Dishwasher manufacturers have made remarkable strides in improving energy efficiency over the past decade. Thanks to innovations in water heating, insulation, and motor technology, modern dishwashers deliver excellent performance while using less water and energy.
