Does using dimmers increase power consumption?


No, I don't know from where you got the idea. Dimmers are actually used to reduce power consumption and thereby being energy efficient. Dimmers actually take advantage of the AC current flowing to it and will rapidly switch on and off the current. This happens so fast that you won't recognize power being on and off. This way dimmer switches save power. But to get the real benefit of a dimmer you must change from incandescent lights to CFL. You can actually expect to save about 25-40% of the energy normally used if you dim the bulb to 50% brightness.

Air Conditioner SEER Seasonal Energy Efficiency Ratio


Energy consumption for home air conditioning accounts for almost 5% of all the electricity produced in the USA. Energy Policy Act mandates minimum energy efficiency standards for commercial buildings, using research and standards developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. Energy Star qualified central air conditioners have a higher seasonal efficiency rating (SEER) than standard models, which makes them about 14% more efficient than standard models. Energy efficiency specialists with certified training on retrofits and energy savings on both residential and light commercial units may enable you to save up to 50 percent on your air conditioning bills with the use of a high efficiency energy system. Substantial energy savings can be obtained from more efficient systems.

SEER (Seasonal Energy Efficiency Ratio) is related to the Energy Efficiency Ratio (EER), which is the ratio of output cooling in Btu/Hr and the input power in watts W at a given operating point and also to the coefficient of performance (COP) commonly used in thermodynamics. SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system’s energy efficiency at peak day operations.

The SEER rating is the Btu of cooling output during a typical cooling-season divided by the total electric energy input in watt-hours during the same period. SEER is related to the Energy Efficiency Ratio (EER), which is the ratio of output cooling in Btu/Hr and the input power in watts W at a given operating point and also to the coefficient of performance (COP) commonly used in thermodynamics. SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system’s energy efficiency at peak day operations. The higher the SEER number, the greater the efficiency of your unit. Therefore you will realize greater energy savings. The higher efficiency your product, the lower your long-term energy costs will be. Both central AC and air source heat pumps are rated according to seasonal energy efficiency ratio (SEER).

Before you consider upgrading your cooling equipment, the cheapest way to save money and energy from cooling is to reduce the need for mechanical air conditioning in the first place. Ask your contractor about a variable speed air handler, which will improve comfort and efficiency and allow continuous air filtering at minimum energy cost. Also, because ducts are often responsible for a lot of wasted energy, make sure you hire a contractor who knows about high-efficiency installations. If your central air conditioning unit is more than 12 years old, replacing it with an Energy Star qualified model could cut your cooling costs by 30 percent.

Air Conditioning Programmable Thermostats - Great for Heating and Cooling


Programmable thermostats contribute to overall system performance, maximizing energy savings while providing complete comfort control. They also allow flexibility to homeowners because they can be programmed to match their lifestyle. Programmable thermostats save energy by turning down the cooling and heating system at night or at times when your home is typically unoccupied.


Did you know that properly using a programmable thermostat in your home is one of the easiest ways you can save energy, money. Homeowners can save about $180 a year by properly setting their programmable thermostats and maintaining those settings. They can achieve significant energy and money savings that are possible through the proper use of your programmable thermostat. Programmable thermostats do two things:
(1) Compare the thermometer reading of a room's temperature to the "ideal" thermostat temperature you select.

(2) Give start-and-stop commands to the heating or cooling system in order to achieve an indoor temperature that is as close to your "ideal" thermostat setting as possible.


Your savings will largely depend on the length of your energy saving program periods and the temperatures set. For example, an energy saving period of 10 hours with the temperature set back 10° will save more than a 5 hour energy saving period with the temperature set back 5°. By maintaining the highest or lowest required temperatures for four or five hours a day instead of 24 hours, a programmable thermostat can pay for itself in energy saved within four years.

A programmable thermostat will keep you and your home comfortable while you are there to enjoy it, and will change the set point at programmed times to an energy savings level when you are not home. The precise temperature control of a programmable, energy-saving thermostat saves wear and tear on high-efficiency heating and cooling equipment by properly cycling the equipment. A programmable thermostat will keep you and your home comfortable while you are there to enjoy it, and will change the set point at programmed times to an energy savings level when you are not home.


Controlling your heating more effectively could save you up to 17% on your heating costs. In fact, during the winter you can save about 3 percent of your heating costs for every degree you lower your thermostat. Begin lowering your heating bill immediately with the pre-programmed 7-day schedule, or modify the programming to suit your lifestyle. By delivering the heating or cooling when you need it, and optimizing temperature for activity, sleep and times you are away you can maximize your comfort level and save energy.

Advantages in basic calculators?


Hi Heavenknows9,
The advantages of a basic calculator is that it saves valuable time for productive learning, especially at a higher level where the basics has been mastered, and more emphasis is placed on concept understanding. Only upon achieving the objective, can the teacher allow them to use back the calculator to move forward to other topics. This ensures that no part of the math education is missed out. Thus, calculator, though may seem detrimental to math studies, can be beneficial when the intent of usage is proper.

I"m a new owner. Would like to know if it is desirable to shut printer off each time it will not be used for 4-12 hours.


It's always best to shut off a machine while it's not being used. There are several advantages like you save energy (power), save power cycles, etc..etc..

If you need further help, let me know.

Good luck.

Thanks for using FixYa.
