!±8± Solar Power - Fun Facts

Fun facts about solar power are popular at any age. People want serious information about solar power, but sometimes, even the serious can be expressed in fun facts.

Fun facts on solar power include things such as the fact that, in a single hour, enough sunlight reaches the earth's surface to meet the entire world's energy needs for a full year. Imagine! That information comes from the American Solar Energy Society.

Here are some more fun facts on solar power.

12 Fun Facts on Solar Power

* As early as 1921, the Nobel Peace Prize was awarded for experiments with solar power and photovoltaics. It was awarded to Albert Einstein.

* When silicon is taken from just one ton of sand, and used in photovoltaic solar power panels, that silicon can produce as much electricity as 500,000 tons of burning coal.

* In the U.S., there are more than 10,000 homes that get their energy entirely from solar power.

* Nearly 200 years ago, a British astronomer by the name of John Herschel cooked food with solar power during an journey to Africa.

* California opened its first large solar power plant in 1982.

* Solar power can cut water bills by more than 50 percent each year in a home where a solar model replaces the electric water heater.

* The price of photovoltaic (PV) solar power panels has dropped 200 percent over the last 30 years, according to the Department of Energy. Owners now pay between 10 and 40 cents per kilowatt-hour.

* A study by the U.S. Department of Energy (USDOE) showed that solar power conditions were close to perfect (99 percent) in San Francisco on June 14th, 2000. On that day, 100,000 customers in that area lost power. Solar power could have provided all they needed.

* Another USDOE study showed that the roofs of California's city and county buildings, if covered with solar PV panels, could generate 200 megawatts of clean electricity! Cover California's school roofs with solar power panels, and you add 1,500 megawatts more to the state's peak power supply.

* In California, covering every available commercial and industrial roof with solar power panels could generate all of the electricity needed in that state during the daytime.

* Germany is making the best use of solar power, even though its climate includes many cloudy days.

* It takes only about 8 minutes for solar energy to travel from the sun to the earth.

Tools Needed By Electricians

In order to work with electricity, one needs the proper tools and equipment. There have been many advances and improvements in the types of tools that are now available. While there are many tools that can be useful to an electrician, there are some that are of primary use, which are almost always employed, even when there is a need to limit the number of tools that are taken to a particular job site.

Electrician Tools Needed : Hand Tools

An electrician needs a number of basic hand tools, to perform basic tasks.

These include:

Square screwdrivers and Phillips screwdrivers, in a variety of sizes and lengths, as well as nut drivers and a hex key set. An assortment of pliers, including long-nose pliers, needle-nose pliers, side-cutting pliers, diagonal cut pliers, and channel lock pliers.

Wire strippers, hacksaw frame, cut off saw, a pair of tin snips, key hole saw, razor knife, and an electricians knife. Adjustable wrench, tap wrench set, crescent wrench, half round file with handle, cold chisel, scratch awl, reamer, tri-tap and center punch. Wire strippers, fish poles and fish tapes, basic tape measures, square, wood folding rule, and laser measuring tool. Level, torpedo level, chalk line, razor blades, electricians hammer, fuse puller, flashlight, carpenters pencils, nail puller, and labeling machine.

Electrician Tools Needed: Power Tools and Testers

There are also a number of power tools which are important to an electrician, such as power drills, cordless screwdrivers, reciprocating saws, spiral saws, and portable band saws. An electrician also needs a tool box or tool bag, an electricians belt, and an electricians pouch in order to keep all tools organized and safely accessible.

Electricians also need tools specifically designed for working with the electrical current, such as a 600V AC/DC vol-con tester, volt-amp meter, neon circuit tester, power testers, and VDV tools and testers.

While not all of these tools are needed on every job, as a general rule an electrician needs to have a wide assortment of tools, to insure that they have the correct tool for the job. Many of these tools are actually carried with the electrician on their electricians belt, and as such, there is a tendency towards choosing lighter weight and smaller tools whenever possible, not only to make them more portable, but because these are often the safest choice for the job. In addition to choosing lightweight tools, electricians should always choose the most ergonomically designed tool possible, to reduce the risk of repetitive stress on the job.

Electrician Tools Needed: Safety Equipment and Precautions

In addition to the various tools listed above, an electrician needs to have all the necessary safety equipment that would be needed for any given job site, such as possibly safety glasses, insulating gloves, dielectric footwear, and arc and flame resistant clothing. There are several different types of blankets and shields that might be needed by an electrician, such as an arc suppression blanket and an insulating shield or blanket.

Hand tools should be double insulated, and if the work environment demands it because of flammability issues, tools should also be non-sparking. The particular tools that are chosen for any given job should always be given careful thought, to insure that the choices are effective, efficient and safe for the work to be performed.
