One of my problems is that it's just so difficult to separate myself from my computer. However, by doing so I'll save electricity and in turn, save the Earth. A sacrifice.
Turn it off. JUST DO IT.
The Final Problem?

Multi-usage
The hot air released from a portable air-conditioner can be used to dry mopped floors or provide a heat to dry clothing, especially in rainy days. It can also be used to keep a storage room dry.
Earth Hour
Earth Hour is an initiative to help Earth reduce the energy sources depletion crisis. It is an annual worldwide event where people around the globe are encouraged to switch off their lights and other electronic appliances for one hour. It was an effort to reduce the use of fossil fuels and also reduce global warming.
The Cost of Air Conditioning Vs. Fans
- A good window AC unit
* Runs on 1.2 kilowatts and costs 14 cents an hour to run.- A three-ton central air unit (a common cooling system),
* Runs on about 3 kilowatts and costs about 36 cents an hour to run.
- A good ceiling fan
* Draws only 30 watts to run, costing about 1 cent per three hours of use.
* Uses less than 1% of the energy of AC units.
Running the Cost Figures Over a Month
- A window AC unit
$50.40 per month
- A central AC unit
$129.60 per month
- Each ceiling fan
$1.20 per month
Save over $128 per month by putting up a ceiling fan and weening off of AC.
Additional Benefits to Getting Rid of AC
- 25% of all electricity consumed at home in the U.S. is to power AC units.
* Most of that electricity is coming from carbon-rich coal.

EPA's cleanup recommendations for a broken CFL
http://greenhomeguide.com/askapro/question/i-broke-one-of-those-twisty-lightbulbs-i-read-that-this-means-my-home-is-mercury-contaminated-true
Before Cleanup
- Have people and pets leave the room.
- Air out the room for 5-10 minutes by opening a window or door to the outdoor environment.
- Shut off the central forced air heating/air-conditioning system, if you have one.
- Collect materials needed to clean up broken bulb: stiff paper or cardboard; sticky tape; damp paper towels or disposable wet wipes (for hard surfaces); and a glass jar with a metal lid or a sealable plastic bag.
During Cleanup
- Be thorough in collecting broken glass and visible powder.
- Place cleanup materials in a sealable container.
After Cleanup
- Promptly place all bulb debris and cleanup materials outdoors in a trash container or protected area until materials can be disposed of properly. Avoid leaving any bulb fragments or cleanup materials indoors.
- If practical, continue to air out the room where the bulb was broken and leave the heating/air conditioning system shut off for several hours.

Compact fluorescent lamp (CFL)
- Also called:
* Compact fluorescent light
* Energy-saving light
* Compact fluorescent tube,
- A fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps.
- Uses a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
- Gives the same amount of visible light as incandescent lamps.
- Uses one-fifth to one-third the electric power.
- Lasts 8 - 15 times longer.
- Higher purchase price than an incandescent lamp.
- But saves over 5 times its purchase price in electricity costs over the lamp's lifetime.
- Like all fluorescent lamps, CFLs contain toxic mercury which complicates their disposal.
- In many countries, governments have established recycling schemes for CFLs and glass generally.
- Improved phosphor formulations have improved the perceived color of the light emitted by CFLs, such that some sources rate the best "soft white" CFLs as subjectively similar in color to standard incandescent lamps.

How to Make Glow Jars
They're wonderful decorative items and I just thought, couldn't they be a nice solution to replace nightlights? Or just brighten up dark rooms? This will also reduce the use of electricity to power residential lighting and it might help out in rural areas.

Highlighter ink jar
Poster paint jar
http://www.wikihow.com/Make-Glow-Jars
Highlighter ink jar
- Cut open a highlighter with care. Remove the felt stick (ink cartridge) located inside the highlighter. It's recommended that you wear disposable gloves when handling everything, to avoid staining your skin. Also, place something over your workspace to prevent staining (this tutorial shows a piece of unwanted carpet off-cut placed over the work surface.)
- Put the highlighter ink cartridge in the jar. You only need one cartridge per jar.
- Fill the jar with plain water.
- Mix the liquid around a bit. Then, let it sit for a day to achieve the best effects.
- The following day, take out the highlighter cartridge. You should find the result is one cool looking jar. To use, place under black light and you'll get a great glow for parties, trick and treating or stage props.
Poster paint jar
- Instead of highlighter fluid, you can also try a bit of poster paint in fluorescent colors. With most brands, this will turn out fabulously. Just add enough paint to color the water, and mix well.
- To make it glow, try using purpose-made poster paint. Glow-in-the-dark poster paint is readily available almost anywhere, and will make your jars glow in the dark for up to a quarter of an hour after turning out the lights.
Photovoltaic Cells
Photovoltaic (PV) cells:
- Photo = light
- Voltaic = electricity
- Convert sunlight directly into electricity.
- Made of special materials called semiconductors such as silicon, which is currently used most commonly.
- Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. (The energy of the absorbed light is transferred to the semiconductor)
- The energy knocks electrons loose, allowing them to flow freely.
- This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off for external use, eg. to power a calculator.
- This current, together with the cell's voltage, defines the power (or wattage) that the solar cell can produce.

Humans have an intimate relationship with electricity, to the point that it's virtually impossible to separate your life from it.
Sure, you can flee from the world of crisscrossing power lines and live your life completely off the grid, but even at the loneliest corners of the world, electricity exists.
If it's not lighting up the storm clouds overhead or crackling in a static spark at your fingertips, then it's moving through the human nervous system, animating the brain's will in every flourish, breath and unthinking heartbeat.
We take electricity for granted one second and gawk at its power the next.
Electricity powers our world and our bodies.
Harnessing its energy is both the domain of imagined sorcery and everyday life.
Despite our familiarity with its effects, many people fail to understand exactly what electricity is -- a ubiquitous form of energy resulting from the motion of charged particles, like electrons.
When put to the question, even acclaimed inventor Thomas Edison merely defined it as "a mode of motion" and "a system of vibrations."

With efficient use of electricity, we can reduce the usage of fossil fuels
- When gas prices skyrocketed at the start of the 21st century, the world faced a rather startling reality:
* Our primary energy supply, fossil fuels, is even more unstable than some of us thought.
* Fossil fuels are finite and frighteningly subject to market, political and geological trends.
* Renewable energy includes solar power, wind power, geothermal energy, biofuels and hydropower.

Generating Electricity
Electricity:
- Mostly generated in places called power stations.
- Power stations use heat to turn water into steam.
*The force of the steam pressure turns giant fan-like structures called turbines, which are linked to machines called 'generators'.
* Generators have a head with wires which spins inside a magnetic field.
* Electromagnetic induction causes electricity to flow through the wires.
- Generating electricity without heat:
* Natural flow eg. wind power or water power can be used to directly turn a generator.
- Heat sources can be classified into two types:
* Renewable energy resources : The supply of heat energy never runs out.
* Non-renewable energy resources : The supply will eventually be used up.
- Solid-state electricity sources have no moving parts.

Introduction to Electricity II
Electricity:
- Occurs when electric charge flows.
- An energy source used to power machines and electrical devices.
- Scientists have found that we can make electricity if:
* We pass a magnet close to a metal wire
* We put the right chemicals in a jar with two different kinds of metal rods
* We rub two things together, eg. a wool cap and a plastic ruler. (Static electricity)
- Electricity can flow like water from one place to another, either as a spark or as a current in a metal.
- All matter has an electric charge, but this is mostly cancelled out by the presence of matter with an opposite charge. We only see an effect when there is too much or too little electric charge in one place so that it is not cancelled out.
- Since the 19th century, electricity is used in every part of our lives.
- Most of our electric energy are from generators. The biggest generators are in power stations. Some are from photovoltaic cells or batteries.
- It arrives at our homes through wires from the places where it is made.
- Examples of application of electricity:
* Electric lamps - light
* Electric heaters - heat
* Washing machines, electric cookers - doing work
* In factories - running machines and computers.
- Electricians deal with electricity and electrical devices in our homes and factories.
