**Energy Consumption Formula**

**Energy consumption**Â is the use of power or energy of a system by making use of supply.Â The consumption is done in Giga Joule per year, kilograms of oil equivalent per year (kg/a) and in Watts.

**The energy consumption formula is articulated as,**

Where,

E is energy in kilowatt-hours(kWh),

P is power in Watts,

t is hours per day.

**EnergyÂ Consumption SolvedÂ Problems**

**Here are some cracked examples based on Energy Consumption: **

**Problem 1:**Â Compute the energy consumption in a system that consumes 190 Watts of power and works for 3 hrs a day.

**Answer**:

Given: Power P = 190 W,Â t_{h}/day = 3 hrs

Therefore, the energy consumption is 2052J

**Problem 2:**Â A toy car consumes energy of 500 Watts of power if it works for 2 hrs a day using it. Calculate the energy consumption a day.

**Answer:**

Given: Power P = 500 W,Â t_{h}/day = 2 hrs
