Surge protection and joule ratings for laptops determines its level of protection from electrical damage. When an external surge is detected, the protection equipment immediately blocks it.

What unit or measurement is used to describe the amount of work a surge suppressor can do before it stops protecting the circuit?
Depends on a type of protector. Some protectors work by absorbing energy. These might be rated in joules (pronounced 'jewel'). Are typically hundreds or a few thousand joules. Another protector for all types of surges works differently. It is measured in amps. For example a typically destructive surge (lightning is one example) might be 20,000 amps. So a 'whole house' protector is minimally 50,000 amps. Protector must not stop working. If properly sized, it only degrades. Protector that is grossly undersized stops working in a manner that violated the manufacturer's specifications. And that is a potential fire. A typically destructive surge can be hundred of thousands of joules. What does that do to the first type protector that must somehow absorb that energy? Two type protectors. One rated in joules. The other in amps.
How many joules are needed to melt 2 grams of water?
2,26 Kj are necessary
How many joules of heat are necessary to melt 500g of ice ar its freezing point?
334 j/g =167000 j
How many joules of energy are necessary to heat the steam from 100.0 degree c to 114.0 degree c?
That completely depends on how much steam there is. (mass)
How many joules of energy are necessary to heat the steam from 100.0 AC to 114.0 AC if the specific heat of steam is 2.01 Jg AC?

How many Joules of protection do you need in a surge suppressor?
A suppressor is rated in joules, and a suppressor is rated as to the amount of joules it can expend before it no longer can work to protect the circuit from the power surge.I think you can find the answer to this question in Dehn-usa.com's "Lightning Protection Guide" or their "ABC's of Lightning". I put the link under the related links below.

What type of lightning protection equipment do I need for my house I just purchases in Evansville, Indiana?
There are many types of lightning protection equipments such as grounding units, surge suppressors, and conductors. If you have electronic equipments, definitely get surge protectors.
What is a surge strip?
A surge strip is an electrical device that protects your valuable electronics from dangerous power surges, spikes, and overloads. However, many surge strips they have in production today does not support protection against power spurts.
How many joules are necessary to heat a sample of water with a mass of 46.0 grams from 0.0?
46 calories (or 192, 464 joules) for each Celsius degree.
How many joules of energy are necessary to heat a sample of water with a mass of 46 g?
46 calories (or 192, 464 joules) for each Celsius degree.
What power company provides surge protection service for homes?
There are many Electric Utilities throughout the United States that offer Surge Protection to their customers or at the very least can recommend a reputable company to refer you to. You can usely find out this information by going to your Electric Utility's web site. Most Utilities will list their Surge Protection Programs under either "Products and Services" or "Member Services".

What unit of measure is used to describe the amount of work a surge suppressor can do before it stops protecting from electrical surge?
There are 3 items that can be used for surge suppression measurements. Most of the plug in strips use Joules as a measure but this can be very misleading. Joules is a measure of energy. Energy is current (amps) times voltage (volts) times time (seconds) or E=I*V*t. Voltage during a surge is critical in determining if downstream equipment is protected. So low voltage rating are important. Current during a surge is important as this is a measure of how many amps are flowing diverting the surge from the downstream loads. So high surge current rating are important. Time is not generally critical, but is determined by the characteristics of the surge. For standard surge testing, the time is identical for the same waveshape. So Joules appears useful at first glance because it incorporates voltage and current in one measure. However, one can increase the joule rating by increasing the voltage (bad) while decreasing the current (also bad). Joules can also be manipulated by using waveforms that are not standardly used in the industry. So rather than use Joules, it is much better to look at the voltage during a surge and the maximum surge current a product uses and ensure the testing is with a recognized standard surge waveform.
