# Computing Your Energy Consumption

**Not everyone is an expert in physics**. But with regards to the concept of energy consumption, it should be something of common sense. As a matter of fact, *knowledge of energy use is a great initial step in making the necessary changes to your electricity bill* and optimizing your energy consumption.

Kilowatt which is abbreviated as kW is a known standard to measure electricity. __1 kW is equivalent to 1000 watts__. The power company is charging its customers by how much electricity they are using per kilowatt-hour or kWh. In other words, this is measuring the number of kilowatts being used over a certain period of time.

**Simple Mathematics**

So to give you an example, a light bulb with 100 watts use .1 kilowatts per hour. It’ll take 10 hours for it to consume 1kWh of energy. In the event that the power company is charging you at .10 dollars per kWh, then you’d be expecting to pay .10 dollars every 10 hours to be able to use light.

It might seem to be a relatively small amount but as it adds up every day for the entire month, then that’s something.

For you to find out the kilowatts being used by an appliance, you just have to use the following equation:

*Formula: Watts / 1000 X hours used = Your kWh Consumption*

Say that you have a 400-watt radio used for an hour today, divide the radio’s wattage by a thousand or 400/1000 = .4. Now, we got an idea that you’ve consumed .4 kW of energy for listening to radio. Then, we need to multiply the kW by hours used to figure out the kWh used. For this scenario, you’ve just used .4 kWh. But if you’ve listened for like 4 hours, then multiply it to 4 and you’ll get .16kWh.

Now, let us say that you are using your computer to generate profits and a certified * Streamerplus* account holder, then expect that on the computer alone,

**it will cost you big price on the electricity**. This is why you have to be vigilant with your energy consumption.
