People and energy
People found sound energy are annoying
noisy sound distracts people sometimes
construction work sound
car engine sound
Electrical energy is the most commonly used energy
Household appliance need electrical energy to work
Television
Fan
Computer
Lights
Other energy is converted to electrical energy for household uses
Wind turbine
wind spins turbine to allow the motor to convert kinetic energy to electrical energy
Burning of fossil fuels
Fossil fuels were burn to generate steam thatdrives large turbines that produce electricity
This method causes climate change
hydroelectric dams
flowing water flows through turbine to convert kinetic energy to electrical energy
People need energy to do things
Food and drinks have chemical potential energy to provide people with the energy to move and do things properly
