Calculating Energy Costs

Posted by ghost

As every engineer knows, energy calculation is straightforward. The unit of electrical energy is the kilowatt-hour (kWh), found by multiplying the power use (in kilowatts, kW) by the number of hours during which the power is consumed. Multiply that value by the cost per kWh, and you have the total energy cost. Total energy cost = (Power in watts/1000) × hours operating × cost per kWh Maxim's Energy Cost Calculator makes the calculation even easier.
