In one sentence, describe what the following article is about: The power in watts is the rate at which energy is generated or used. Many utility companies will bill you based on how many watts of energy you used. The watt is basically how much energy an appliance uses. Rated watts are the amount of watts needed to keep an appliance running. For example, refrigerators usually require 500 watts to keep running. You may need to know the watts in your home if you are trying to become more energy efficient, add solar panels, or use a generator. Electrical power comes in AC and DC currents. AC means alternating current; the electrical current constantly reverses direction and is used often in homes and offices. DC means direct current, and it means the current only travels in one direction. You will find it in things like battery packs. Surge watts means the amount of watts needed to get an appliance started by igniting its motor or compressor. For example, it might take 2,000 watts to start the motor and compressor of a refrigerator. Watts are a basic unit of power (electric, mechanical, or thermal). The reason watts matter is because you can improve energy efficiency if you understand them. Lower your watts, and you will improve energy efficiency and save money. Here's an example. Let's say you are buying a light bulb, and one is 100 watts and the other is 23 watts. If the 100 Watt bulb is cheaper, you might assume it's the better purchase. However, over time, the 23 Watt bulb will save you money. Do simple subtraction to determine the watt difference. In this case, that is 77 watts (100-23). Utility companies will often charge you using kilowatts. To find out the number of kilowatts, take the number of watts divided by 1,000. Then take the number of kilowatts multiplied by your hours of usage. This is the kilowatt/hr. Then, take kilowatt/hr and multiply that number by the cost of your energy. This is your annual cost. For example, let's say you have 10 lights. They are each 100 watts. 10 X 100 = 1,000 watts. 1,000 Watts divided by 1,000 = 1 kW. Let's say you've used 2,000 hours of energy. Thus, 1kW X 2,000 hours per year = 2,000 kwh. Let's say your utility company charges you 10 cents for every kilowatt hour. You would take 2,000 kwh X .10 = $200, That's what it would cost you to use those bulbs for the year.
Summary: Understand why watts matter. Become more energy efficient.

In one sentence, describe what the following article is about: Office showers are a little tricky because there's no clear cut rules for whom you should invite. Depending on who is throwing the shower, you may want to keep it small and invite only the bride's closest colleagues. If the bride has worked at the office for a long time, try reaching out to former co-workers who have already left, who the bride has strong relationships with. If the bride has good ties to vendors or other partners of that company, consider inviting those people as well. If the bride's boss or a member of her work team is throwing the shower, invite everyone else on that team as well. Make the shower into a team bonding experience and make sure everyone feels included. Make sure the team goes in on one gift, so nobody feels obligated to buy something independently. If the shower is being held off-site, consider inviting the groom to show up half-way through the event. If the bride has worked at the company for a long time or holds a very visible position, consider making the invite open to everyone. This way, no one feels excluded, but no one feels coerced into attending either. If the office is springing for a gift, make sure people are aware they are not required to contribute. This can be awkward for people who don't know the bride well. Office showers do not need to be restricted just to people who are attending the wedding. Many co-workers will not be invited to the wedding, but should still be included on the shower guest list.
Summary: Invite the bride's friends. Invite the bride's team. Invite the whole office.

In one sentence, describe what the following article is about: to determine the best water purifying option. Before you determine how to filter your water, send a sample to a laboratory for testing. This will give you a better idea of what harmful minerals besides iron are in your water and help guide you when choosing a water purifying system. Water softeners are generally equipped to replace iron with other minerals in water but may not remove more harmful minerals, like arsenic or sulfur. If you have tested your well water and found other minerals besides iron in it, another option might suit your needs better. Water softeners work by replacing iron minerals with sodium, and they require salt to work. If you cannot currently handle a high sodium diet, another iron removal method (like oxidation filtration or reverse osmosis) might be ideal. Because sodium cannot be absorbed in significant quantities through the skin, using a water softener is safe for low-sodium diets for water that you wash or clean with. Every water softener system is differentsome are simply attached to your well water pump or faucet and can be installed on your own. Others, however, may require professional help to install. Read your model's instructions and, if you are unsure how to properly install the system, call a plumber or the company you bought the system from for assistance. While purchasing water softener salt, look for high-purity options like evaporated or solar salt. These will leave less of a residue in your softener tank. Some water softener salts are made specifically for high iron concentrations. Check the label to find the right salt for your water. After you have installed your water softener system, send another sample to a nearby laboratory for testing. Check for any harmful minerals remaining in the water that your softener system might not have filtered out. If significant levels of any harmful mineral remain, you may want to try a different filtration option.
Summary:
Test your well water Choose a water softener exclusively for removing iron. Avoid water softeners if you are on a low sodium diet. Install a water softener system yourself or call a professional. Use high-purity salts in your water softener. Test the well water again after installing a water softener system.
