What affects energy bill?
The amount of power that a household consumes depends on how many appliances there are and the amount of time they are in use. Some appliances or machineries take a lot of energy to operate, so it will result in more use of power. We pay for electricity in kilowatt-hours (kwhs).

What is an energy transformation example?
For example: Plants capture light energy from the sun and convert it into chemical energy during the process of photosynthesis. Wind turns a wind turbine to produce mechanical energy, which activates an electrical generator to produce electricity for a radio.
What is a sentence for energy transformation?
A toaster transforms electrical energy into thermal energy. 2. A blender transforms electrical energy into mechanical energy.
Why must energy be changed from one form to another?
Thermodynamics is the study of energy. First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.
What increases the electric bill?
Aging appliances, overdue maintenance on appliances and windows or doors, and running extra appliances that are no longer needed are among the top three culprits that cause high energy bills.
