Smart Behavioral Change

Do not turn on all of your air-conditioning HVACs and lights at the same time.
When the sun was beating through the windows during the day, using fan to dissipate the hot air inside the room before turning on the air-conditioning.
To raise the air conditioning set temperature by one or two degrees while using fans will help you save more energy and more.
In order to keep your room cool, using the blind and curtain during the afternoon so the radiated heat can stay out.

Changes in energy demand will likely affect greenhouse gas emissions, but the net effect depends on which energy sources are used for electricity and cooling.

To improve energy efficiency, it often costs investment up-front but in many cases this capital outlay will be paid back in the form of reduced energy costs within a short time period.

Energy performance contract is getting popular in the U.S. which requires no up-front investment. This makes efficiency improvements an attractive starting point for reducing carbon emissions.

To increase efficiency in non-domestic buildings often means focusing on ventilation and air-conditioning, in addition to lighting, heating and appliances. Many such buildings have achieved savings of around 25% after undergoing a retrofit to increase efficiency.

To lower carbon emissions on the supply side, for example, switching electricity generation from fossil fuels to renewables.

To lower emissions on the consumption side through reduced consumption and substitution, for example, do more walking to replace short-distance transportation or using a bicycle for a short journey instead of a car.
