In dealing with the vast subject of Green Energy, a lot of time was ...
LED COMPARISONS
LED (or Light Emitting Diode) lighting products are quickly taking over the incandescent lamp world. They are meeting the needs of the present, without compromising the generation of the future’s own needs. LED lamps use up to 75% less energy than incandescent lamps, without the production of carcinogenic materials (such as lead and mercury) [...]
ELECTRIC CAR CHARGING STATIONS
Electric car sales are increasing and therefore the need (or at least the future need) of charging stations. Charging stations are being added in residential garages, carports and exterior parking areas, as well as parking garages of commercial and government buildings. I have even seem them popping up in municipal bus stations and parking lots. [...]
THE BUSINESS OF GOING GREEN
Driven by unstable fuel prices, increased energy consumption and government regulation, the business of going green is soaring. The Energy Independence and Security Act has set in motion green building technology implementation in federal buildings. The bill includes provisions to improve energy efficiency in lighting, appliances, and equipment. At the same time it pushes for [...]
SOLAR POWER STORAGE USING MOLTEN SALT
A major deterrent to the development of solar power generation, is the ability to store on a large-scale, the electricity produced during the day for use at night. The only true options to this point are to use solar photovoltaics (PV’s) only when it’s sunny or to charge batteries. The charging of batteries [...]
D.I.Y., TYPICAL 200-AMP RESIDENTIAL SERVICE CHANGE OUT
Service configurations may vary from home to home, but all have similar characteristics. We will discuss the most common service changes and you will have to adapt these principles to your unique situation. Let me state at this juncture, that service changes require the power to be removed from your home and the work [...]
SOLAR COSTS FALLING
A September 2011 report from the US Department of Energy (through its Lawrence Livermore National Laboratory) states: “The cost to install a photovoltaic system (solar collection and electrical power conversion) has fallen by 17% or $1.30 per watt, from 2009 to 2010, with similar results from January through June 2011.” Factors are: A drop in [...]
D.I.Y., SO YOU THINK YOU NEED AN ELECTRICAL SERVICE CHANGE?
There are signs and events to look for as a service nears its life span, or has more than likely become overloaded. In this search you may want to ask yourself the following: Is your service over 50 years old? Is your main breaker under 100-amps? Are the entry wires–or riser–from the power company, to [...]
D.I.Y., HOW TO WIRE A FOUR-WAY SWITCH
If you have an existing light fixture which is controlled by two three-way switches (2 different switch locations) and want to add a third switch at a different location, you must install a four-way switch. If you are building a new home, or putting on an addition and want a fixture [...]
D.I.Y., INSTALLING A SURFACE FIXTURE, RECESSED FIXTURE OR CEILING FAN
There are several things to consider before you start on installing a surface fixture, recessed fixture or ceiling fan: 1. You must be able to install a switch leg (2-wire cable with ground) from a switch to the fixture or fan–this most often requires attic space between the two. 2. A heavy fixture or fan [...]
