Incandescent bulbs waste energy by using more power that other types of bulb.
An incandescent produces about 10 lumens of light per watt of electric power.
A halogen produces about 13 lumens/watt
A compact fluorescent (CFL) produces about 50 lumens/watt.
Read the package on the bulb. Look for the LUMENS then the WATTS. Dividing the LUMENS by WATTS will give you the LUMENS per WATT of the bulb. Then compare this value with all the other kinds of bulbs, both the incandescent and the halogen types.
Also consider the time the bulb will spend 'on' - short cycles will reduce the life expectancy of fluorescent lights considerably.
Finally consider that fluorescent lights contain Mercury which is poisonous.
Another opinion
Saying that the mercury in mercury lamps is dangerous is an urban myth which comes from the old styles of mercury discharge lamps and fluorescent tubes used over fifty years ago, which did indeed contain about a gram of liquid mercury!
While in use such a lamp was not dangerous at all, but if the glass tube or bulb got broken the "blob" of mercury could certainly be dangerous to human health if anyone picked it up with their bare fingers or swallowed it to see what how it tasted.
Mercury is the only example we have on Earth of a metal that is in its liquid state at room temperature. It was such a "curiousity" that several people did get ill - and may have died - from poisoning by mercury, but not much of it would have came from old fashioned "mercury lamps"!
That said, anyone who advises you that "fluorescent lights contain mercury which is poisonous" about today's fluorescent lamps is making a very misleading statement which could be intended just to frighten people.
No matter whether they are the "compact" or the "long tube" types, modern fluorescent lamps contain only an extremely tiny amount of a special mercury amalgam so that, whilst a modern lamp is in use, there is absolutely no danger to anyone.
However, if such a lamp gets broken, then care must be taken to sweep up all the fragments carefully and dispose of them sensibly in something strong enough not to be cut by the broken glass, such as an old corrugated cardboard box or similar bound around with gaffer tape to stop it from being opened easily.
Today, the main danger to people is the risk of getting cuts from the shards of glass, not from mercury poisoning!
The answers to the Related Questions shown below give a lot more information about how compact fluorescent lamps work and about the very good savings you will achieve in the cost of electricity if you use them instead of normal incandescent lamps.
The power in watts should be marked on the bulb. If a bulb is 20 watts, it will use 20 kilowatt hours in 1000 hours of being switched on.

What is the difference between a green building and an ordinary building?
A green building uses as many methods as possible to reduce the use of carbon-based energy. It would contain the highly efficient lighting elements (compact), possibly there would be alternate energy sources like solar units or wind driven units on the building or nearby. Energy efficient design would be built in to a new building, etc.
What is the difference between a filament bulb and energy saver bulbs?
Today, family, shopping malls, hotels and other places are the subject to use fluorescent lamps and energy-saving lamps to illuminate, , now, take fluorescent lamps and energy-saving lamps for example, let's look at the specific effect of LED lighting energy . In the case of the same brightness, 40W incandescent lamp consume 1 KW of electricity in 25 hours, 20W consume 50 hours, and just 5.5W LED bulb consume 1 KW in 181 hours of electricity. In other words, compared to incandescent and LED bulb, LED bulb especially LED tube light and LED flood light can save 80% energy, if we translates into "Earth Hour" campaign, which equivalent to Earth rest for eight hours. Assume that the two shopping centers need to install 500 fluorescent lamps, in the case of the same brightness, we use 18W LED tube light and 40W traditional fluorescent lamp to work 12 hours a day, a year later, the power consumption of LED tube light is 39420 degrees in mall, while power consumption of using traditional fluorescent is up to 98,550 degrees, the power consumption is 2.5 times higher, further depleting the Earth resources. In addition to energy-saving, environmental the advantages of LED lighting is also very obvious. The traditional lamps contain mercury harmful substances such as lead, pollute the environment, LED lighting has pure green light. Furthermore, LED lamp life is up to 40,000 hours or more, even if the end of life, can also be recycled, these are the advantage of traditional lamp unparalleled. Obviously, compared to the "Earth Hour" advocate turning off lights only one hour per year ，year-round use of LED lighting can reduce energy consumption and carbon emissions, we can walk further on the road of green, low-carbon environmental protection further. To this end, the World Wide Fund for Nature (WWF) - "Earth Hour" campaign at the same time, more people around the world put forward the proposal to replace the new LED lighting products. We practical action to fulfill the commitment of the green, the popularity of LED lighting pace must be accelerated. In the lighting field, the industry generally believe that: LED lighting replacing incandescent and energy-saving lamps will eventually be the trend of the times and the future of LED lighting is bound to in the area. Of course，The better performance of the LED light can be more energy-saving and environmental protection, this task falls on the more professional LED manufacturing network.
Are regular light bulbs or fluorescent bulbs worse for the environment?
On the one hand, fluorescent bulbs contain toxic materials that can be released when the bulb is dumped. On the other hand, fluorescent bulbs last so much longer than do regular, or incandescent, bulbs that this problem is minimised. More importanlty, fluorescent bulbs use only about one-fifth the electricity of incandescent bulbs, thus helping us to reduce our greenhouse gas emissions and therefore slow down global warming. Since global warming is by far the greatest environmental danger we face, fluorescent bulbs must be better for the environment.

How could LED lighting reduce our demand for electrical power?
LED in lighting will reduce energy consumption and costs as well as reducing lighting re-lamping and associated maintenance costs, which will both reduce the environmental impact of lighting. Current incandescent lighting technology is based upon a filament and produces significant heat, which is a waste of energy. With LED, the energy is made directly into light, therefore much less energy is wasted as heat. by Rebecca Markham
Hot Trend for Home Offices: Recessed Fluorescent Lighting?
Recessed fluorescent lighting is typically used in areas where indirect light is preferred to reduce glare and other visual disturbances common with the use of fluorescent lighting. This includes offices, classrooms and more recently, home office and workspaces. Fluorescent lights are highly efficient and cost significantly less to operate than traditional incandescent lights. The problem, as mentioned already, is that the use of fluorescents leads to unpleasant effects for some applications. This is why the use of recessed fluorescent lighting has become very popular. With recessed fluorescent lighting, the lighting is indirect. This is an effective way to reduce glare and make the lighting more effective. There are baffles and reflectors that you can install to reduce direct light from recessed fluorescent fixtures as well. When considering recessed fluorescent lighting, you will find that there are many different options for the type and size of fixtures. There are also many different styles of covers available for recessed fixtures. The most commonly used recessed fluorescent fixture is called a troffer and it allows assess through a hinged assembly for easy access. Some recessed fluorescent fixtures can be set up with a battery backup for use in an emergency. Keep in mind that this will result in less output from the light, but ample for safety reasons in the event of a power outage. When you need specific lighting, such as in an office setting, you should talk to a lighting professional in order to find out what the best possible combination of lighting will be for your situation. Depending on the size of the area, the amount of natural light and how many people will use the area, the lighting requirements will vary. A lighting designer is your best advocate when it comes to saving money and increasing efficiency with lighting design. If possible, your recessed fluorescent fixtures should be installed and fully tested prior to the rest of the room being finished. It is probably a good idea to have the walls painted and furniture in place in order to see how everything will flow together with the new lighting.
Why are fluorescent lights curly?
Fluorescent lights have a curly shape because the tube inside is twisted into a compact shape to make it more energy efficient and to allow for a greater surface area for light emission. This design helps reduce the space needed for the light fixture and makes the light bulbs more cost-effective to produce.
What are some tips for living green?
One thing you can do is to reduce waste by recycling and buying items that use efficient packaging. You can also reduce your energy consumption by replacing your light bulbs with compact fluorescent bulbs and buying energ-efficient appliances. Drive less, if possible, or combine trips to save on fuel.
Why does replacing incandescent light bulbs with compact fluorescent bulbs conserve electricity?
Compact fluorescent bulbs are more energy-efficient than incandescent bulbs because they produce light using less electricity. This is due to their use of a different technology that generates less heat and therefore wastes less energy.

Myths and Facts About Fluorescent Lights?
Fluorescent lights are an excellent choice for home, office, and school environments because they offer many benefits. Still, some myths persist that cause consumers to question the use of fluorescent bulbs. Here are the facts about this type of lighting. Myth: Fluorescent lights flicker, causing eye strain and even headaches. Fact: It used to be true that fluorescent lights had an annoying flicker, accompanied by a slight buzzing noise. Improved technology has eliminated these drawbacks. New fluorescent bulbs use an electronic ballast that produces a steady, silent light. Myth: Fluorescents are more energy-efficient than incandescent bulbs, but less efficient than halogen lighting. Fact: Compact fluorescent lights are almost three times more efficient than halogen bulbs (and more than ten times as efficient as incandescent bulbs). Moreover, fluorescent lighting doesn't consume any power when it is switched off. Halogen bulbs, in contrast, utilize transformers that can continue to consume power even when the light is turned off. Myth: Fluorescents are bad for the environment because they contain mercury. Fact: Fluorescent bulbs do contain a small bit of mercury, which means that they must be discarded in a responsible manner. However, not using fluorescent lights will result in even more mercury being released into the environment. This is because other forms of lighting consume more electricity, which is generated at this time mostly through the burning of fossil fuels. This produces power plant emissions containing mercury. The best way to reduce mercury in the environment is to burn fewer fossil fuels by using fluorescent lighting wherever possible. Myth: Fluorescent light bulbs won't fit inside certain light fixtures, such as the ceiling globes used in many factory-built homes. Fact: Again, this used to be the case, but the advent of the compact fluorescent light bulb changed everything. Today's fluorescent bulbs are smaller than a standard incandescent bulb and will fit in any lighting fixture designed for incandescent bulbs. Myth: You can't use fluorescent bulbs with dimmer switches. Fact: You can use dimmer switches that have set levels such as bright, brighter, and brightest -- as long as they are wired for fluorescent bulbs. However, continuous dimmer switches are still not used with fluorescents.
Is it a myth that leaving compact fluorescent lamps on rather than switching them off and on when needed uses more energy and is worse for the environment?
It is a myth that leaving compact fluorescent lamps on uses less energy than switching them off and on when needed. Turning off the lights when not in use saves energy and helps reduce electricity consumption, which is better for the environment.
How can we reduce the energy consumption?
To reduce energy consumption, you can: Invest in energy-efficient appliances and lighting. Turn off lights and unplug electronic devices when not in use. Improve insulation and seal drafts in your home to reduce heating and cooling needs. Use smart power strips to prevent energy waste from electronics on standby.
What is the difference between a green building and an ordinary building?
