- A portable heater (1500W) uses about 1.5 kWh per hour. The estimated cost of usage of a portable heater is about $0.17 per hour. A Baseboard heater of about six feet (250W per feet) which also uses up around 1.5 kWH per hour, leading to an estimated cost of $0.17 per hour.
- Heat pump strips expend more energy than portable heaters. Heat pump strips expend around 10 kWh per hour. That entails $1.10 per hour. This could take a large chunk of your expenses with a dollar every hour you use your heater.
- Most of all an electric heater uses up the most energy. A single hour of use would suck up around 10.5 kWh which is around $1.20 per hour. Imagine how much you would be spending for a single day of use. You would be spending around 30$.

Here are the top tips to save energy in summer.
Revamping Your Refrigerator
Your refrigerator is one of the major appliances that is constantly running and makes a huge dent on your energy bill. This is more on the case of old refrigerators made in the 1990s. This also includes the energy expenditure of freezers as well. Because refrigerators in 1990s used outdated and primitive technology to cool your food, their energy expenditure is relatively more in comparison to modern models.
A refrigerator from 1996 will use about 150 kWh per month which in turn will cost $16.50 per month. A freezer from the same time period will use about 90 kWh which is about $9.90 a month. Newer energy efficient models made in 2005 and later use better technology leading to bigger savings. A large Energy Star Refrigerator (25 Cub.) will use only 60 kWh of energy in a month. This will lead to a monthly expenditure of about 6.60% which is huge difference compared to the 1990’s refrigerator and freezers.
If you’re using an old refrigerator, it’s advisable that you think of upgrading to a new modern fridge. You will be saving more money on your energy bill on the long run.
Extent of Water Usage – Clothes Dryer/ Washing Machine
Your clothes dryer/washing machine not only expends energy but gallons of water as well. While this is inevitable there are a lot of options you have when it comes to using your clothes dryer/ washing machine. A small step to make big savings on your energy savings is to choose what type of load you put into your dryer/ washing machine. A light load will expend about 2.5 kWh and a heavy load will use around 4 kWh of energy per wash. A light load will cost you about $0.28 per load in comparison to the $0.48 per wash. All these numbers might be simple and low individually but they’ll take chunk out of your expenses when all your washes are tallied together.
Your expenditure will be at its highest in terms of your clothes dryer/ washer running on a hot wash with a warm rinse setting. This setting uses about 6.3 kWh per wash, which in terms of money equals $0.69 per wash. Multiple washes like this throughout the month would see your energy bill skyrocket.
You have a third option as well when it comes to using your clothes dryer/washer. Using these appliances with a level scarcity will help you lower your energy expenses greatly. Drying your clothes outside is a good alternative to using your clothes dryer. The open air and sunlight can also maintain the health of your clothes as well. In terms of washing your clothes, you can opt to bucket was them like how our ancestors used to. This method not only cuts your electrical expenses, it will also reduce the amount of water consumption as well.
Save You Time – Dishwasher
Your dishwasher works in similar fashion to your washing machine/ clothes dryer. More than an essential appliance, a dishwasher is more of a luxury that helps in eliminating one of the most boring chores, cleaning dishes. While a dishwasher can save you time and does a standup job, it utilises a lot of water and electricity. You can see the result of this in your energy bill. A dishwasher on a normal cycle (excluding hot water) uses about 1 to 2.17 kWh per load. This means that per normal wash cycle you will be effectively spending about $0.11 to $0.24. In a month, depending on how much it’s used daily you could be seeing $20 down the drain.
One good thing is that most dishwasher models come with an eco-friendly energy saving cycle. This energy saving cycle uses only 0.5 kWh per wash which translates to $0.004 per wash. Pretty neat right? There is also a third option to save even more on your energy bill. That option is to wash all your dishes on your own whenever you can. Just by doing this alone, you can save a lot of money on your energy bill.
