Environment and Technology

Environmental considerations accompany the use of technology and its growth and development.  The environment whether local, global, or interstellar must be guarded as it is not easily restored when depleted or damaged, if at all.

There are many areas to be considered. Below are just a few areas enumerated to encourage your conscience and ultimately, your actions.

Screens – black or white display?

Usually if CRT (cathode-ray tube) technology is employed, it is true that black screens are more efficient than white.  However, the reverse may be true if recent technology, such as LCD screens are used. The resting state of a particular LCD screen could affect its usage. However, the general rule is true.  Flat panel LCD screens require less energy than the CRT screens.

On smartphones using AMOLED displays, black wallpaper is battery-saving.

Wired versus wireless energy consumption

Using wireless charging systems which charge multiple devices consumes less power than singular adapters. In addition, reducing the number of conventional power adapters and wiring also helps eliminate waste in production and disposal.

Smart technology

Smart technology embedded in areas such as home security to environmental building management also saves energy. It may use radio-frequency transmission or existing wiring. Further, it will assist in management of systems that can affect electrical costs and heating and cooling needs.

It still remains true that powering down monitors or other electronic equipment will consume less energy if done as recommended. For example, in general, – screens should be set to go on stand-by after 20 minutes of non-use and hard drives turned off after 2 hours of non-use, assuming no use in the immediate future. Keeping things updated, such as game cards, and updating to new technology will also have environmental benefits.


Batteries and electronic equipment are considered hazardous waste.  There are numerous venues in which to dispose of waste. Ask the vendor where your waste will go. Make sure that it does not ultimately be disassembled in a location that may harm workers and contaminate groundwater.
