Hot days tend to be in the summer, when the daylight hours are longer than winters. And bulbs generate heat which is not desired.
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
Fluorescent light bulbs use less electricity for the amount of light produced.
A light snack!
No light bulbs actually save energy, they use it to produce light. However energy efficient bulbs use less energy than the ordinary incandescent type. To my mind describing them as energy saving is wrong, they should be described as "lower energy" bulbs.
yes
Yes and less likely to break too
Incandescente light bulbs waste quite a bit more energy than most alternatives.
Normal incandescent bulbs produce a lot of heat as well as light, so are not so efficient as low energy bulbs which can give the same light but consume much less electricity
no
By adding more light bulbs
comparing to the traditional light bulbs energy efficient fluorescent light bulbs uses 25% to 75% energy and saves money also and it lasts up to 3 to 25 times long so there is no need to replace energy efficient fluorescent light bulbs often.
Light bulbs use a ton of energy. People have been lately switching to the fluorescent light bulbs which use less energy and last longer and don't give off nearly as much heat.
