A memory module may be described as a printed circuit board, on which memory
integrated circuits are mounted. These modules permit easy installation and
replacement in electronic systems, especially computers such as PCs, workstations,
and servers
Globally, lighting accounts for 10%-35% of the total energy bills, which are substantial.
Need for energy efficiency in street lighting has been increasing due to rising energy
prices and changing climate. This has led to increased adoption of energy-efficient
technologies such as light-emitting diode (LED) to replace older street lighting models
that use a compact fluorescent lamp (CFL) or halogen. The typical cost of a street
lighting system for a period of 25 years is approximately split as 85% for maintenance,
which includes power supply and replacement cost, and 15% of installation cost.
Power prices have continuously increased, and the trend is expected to continue owing
to urbanization. The urbanization is leading to the development of new roads, requiring
additional street light, thereby increasing the power consumption.
