Richard Vande Sompel asked: Once a deck has been constructed it is like an empty stage waiting to be furnished with such items as a table and chairs, a chaise lounger, a barbecue, portable bar and bar chairs. Electrical power can run a barbecue spit, a music sound system but best of all it can power a deck light system that will dramatically tranform an ordinary deck into a sparkling gem under the nighttime sky. Deck illumination is divided into 2 categories: functional and decorative. Both types can be installed permanently or set up temporarily for the purposes of special occasions. Functional deck lighting has 3 different purposes: 1. General illumination – When deciding upon a functional deck lighting system it is important to keep in mind 2 factors. Outdoor lighting does not require as much illumination as indoor lighting and any light fixtures should never be placed in such a way is to shine directly into people’s eyes. There are a variety of ways to keep lights from shining into eyes
Rising energy prices and our diminishing supply of oil threaten our national security. Without access to energy our economy and national defense are vulnerable to collapse. As a solution to our energy needs, we hear political rhetoric to expand oil drilling, but our energy strategy requires a long term solution that means embracing alternative/renewable energy technologies such as solar and wind. It only takes a quick review of oil production statistics to realize how formidable the challenge is that we face. According to the Energy Information Administration (EIA) in 2007, the US consumed 20.6 million barrels of oil per day (bpd) but we were only able to produce 8.5 million bpd, leaving a deficit of approximately 12.2 million bpd

Jeff King asked: Light Emitting Diodes, more often pronounced as LED light bulbs, are small size, solid light bulbs that are highly energy efficient and are vastly replacing standard Incandescent bulbs. They are very energy efficient and consume, relatively, less energy than traditional bulbs. They are very simple in use and have a long rated life. As Led light bulbs are expensive they were not in frequent use until recently or were used as a single bulb application in lighting pens, remotes, electronic items etc. But as technology is getting improved day by day, the cost of led light bulbs is also getting lower and resulting in their use in applications where clusters of bulbs are used like battery items, flashlights and headlamps etc. Their applications are getting expanded day by day and the day is not far away when they become an inseparable part of everyday consumer electronics and would be used in a bunch without much thought required.
