1) Change light bulbs to energy saving bulbs to lower electricity consumption and costs as well as reduce heat production and CO2 emissions. 2) Disconnect phone and device chargers when fully charged or not in use to avoid unnecessary power consumption even when devices are not being charged. 3) Keep tires properly inflated so the vehicle engine works most efficiently and uses only the necessary fuel. 4) Use rechargeable batteries instead of disposable alkaline or nickel batteries to reduce pollution and heavy metal waste. 5) Place a water bottle in your toilet tank to displace water and reduce water usage each time you flush.
