Emerging electrical energy saving technologies and application for greenhouse gas emission abatement

Rational use of electricity can be carried out by better design, precise manufacture, energy save operation of electrical consumers while minimizing the failures, thus improving reliability and availability. Electricity cost of a high power consumer during its life span exceeds 25 to 50-times the total cost, thus computerised electricity management by the contribution of the Department staff can save energy, reduce greenhouse gas emission and cost. There was a virtual laboratory by Internet access developed also by the staff to measure the losses of dc motors reducing electricity input. It is available to all users through an “open for all” web site. A new smart measuring instrument developed by the staff as well targets energy efficiency tests of fractional horse-power motors. It measures voltage, current, rotational speed and temperature of the machine concerned while three tests independent from each other can be performed simultaneously. In built environment the streets will be lighting by newly developed light emitting diodes (LEDs). They are working rather well, their light performances are good and energy saving exceeds 15 to 20-times, the conventional light sources and life span is 10 to 15-times longer as well as stated by the staff.
