Some ways would be to use less gas-powered items, such as some stoves. Communities can encourage carpools and walking. If you were to drive, don't gun the gas and drive at moderate speeds.
In your own home you can conserve energy by turning off lights and electronic devices when not in use. You could also use energy efficient light-bulbs.
Potential energy=PE
PE=mgh
m=mass in kilograms.
g=9.8 m/s
h=height in meters
Data:
mass=500 Kg
h=110 m
PE=(500 Kg)(9.8 m/s²)(110 m)=539000 joules
