Article in English: Do you tend to keep the curtains and blinds closed and flip on the overhead lights? Letting your house flood with natural light instead can lead to big electricity savings. Unless you need strong, focused light to complete a particular task, try leaving the lights off during the day and embracing the sun's rays in the rooms you're using.  Try to set up your family's daytime work and play space in the brightest room in your house. That way everyone can read, work on art projects, use computers, and so on without relying on artificial lighting. Use light-colored curtains and blinds as window coverings. Find coverings that provide privacy but still allow diffused light to flood your rooms. Instead of spreading out all over the house, have your family spend evening hours in just one or two rooms. That way you won't have to light the whole house to enjoy the evening, plus you'll have the added bonus of spending quality time with each member of the family. You don't have to wait until a summer thunderstorm knocks out the power to break out the candles. Choose a night or two a week to leave the lights off and light your family's way with sturdy, slow-burning candles that cast a fair amount of light. Kids will find it exciting, and over time you'll save electricity and cash.  You can use the candlelit nights as an excuse to power down the rest of the house, too. Encourage family members to do activities that don't require electricity, such as reading by candlelight or telling fun or scary stories. Be sure that your children know how to handle candles safely, and that the candles and matches are stored in a secure place when they aren't in use. Leaving a porch light or path lights burning all night long can waste a lot of electricity. Determine whether having lights on overnight is really necessary before flipping the switch in the evenings.  If you have lights around your house for security purposes, consider getting automatic security lights with motion detectors instead of using lights that stay on constantly....
