List Of Energy Expenses For Small Businesses             

1. Light Bulbs

2. Space Heating

3. Desktop Computers

4. Central Cooling Systems

5. Security Lighting

6. Office Copy Machine

7. Monitors

Light Bulbs

The interior lighting of a business is one of the biggest sources of energy expenses. On average a small business can have 50 bulbs operating within their facility. And if they are still using 60-watt bulbs then it is 3,000 watts of electricity being used per hour. However, if you replace the watt bulbs with LED bulbs then it will be only 475 watts of energy per hour.

Space Heating

This type of heater is used by business owners during the winter season. Most business owners think a space heater is the best option compared to central furnace systems. But the reality is furnace systems are less expensive. A space heater will cost you $36.50 a month and the worst part is, for a medium-size office you will need several space heaters in order to obtain a comfortable office temperature.

Desktop Computers

This is the common equipment of for any office setup. In fact, every office has several desktop computers and they cost a great deal in terms of energy. Usually, a desktop computer can use about 250 watts per hour. That means a single computer is costing your company about $250 a year. You can use a laptop instead of a desktop and save lots of energy. A laptop uses between 15 and 60 watts per hour.

Central Cooling Systems

This is another great source of energy consumption. Most of the small businesses operate with old or outdated HVAC systems. This is because a full HVAC system will cost a lot of money. However, if possible then it is best to use new energy-efficient models because a new model can save up to 50% of the cooling costs.

Security Lighting

The lights used for security lighting are completely different from the conventional lights and on average a security light can use up to 2,000 watts per hour. Though this type of light is only used at night but it will cost the company lots of money.

Office Copy Machine

This is a very common office appliance for small businesses. This type of machine uses a great deal of energy even when they are in sleep or standby mode. Usually, a copy machine can use 2400 watts while printing, 310 watts while in standby mode, and 200 watts while in sleep mode. So it means if you are not using this machine, it still costs your business a great deal of money.


Monitors are used to running advertisements, promotional videos, information, and every office setup has quite a few monitors. Using lots of monitors in an office is actually a huge energy expense. On average a monitor can consume around 100 watts per day. So if an office is using 10 monitors then it is 1000 watts per day and it’s lots of energy.
