What's the purpose of Day LIght Savings?

No offense to those who answered.. but they are wrong.  Daylight Savings may conveniently save energy costs now, but that was not the true intentions.  \n\nDaylight Savings was first created to help farmers, when the time changes and it stays darker later, that's because farmers can work longer throughout the day because there is more light so that they can see.  Because we all know that there are no lights on outside at night on a farm.  That's why it was started, and there may be other nifty uses now (like the energy saving) but that is not what the purpose originally was.

You aren't going to get much sun light at night for your solar panel. There are MANY CHEAP nicad battery powered yard lights on the market that use a small solar panel to charge the battery in the day time. They have IR sensors that turn the light on at dusk and off when the sun comes back up. I doubt if you can build one cheaper than you can buy one, if only as a hobby, Edmond's Scientific and Radio Shack sell kits for that use.

I've wondered this myself. I think that in the case of an illuminated sign, the landlord wants to continue to protect the lighting tubes from vandals so its quick & cheap to reverse the plastic panel.

Plants use a very small portion of the light generated by a standard incandescent bulb.  They sell grow lamps which generate a wider spectrum of light that plants can use.

Throw light . \nwhy, doesn't the place get any sunlight.

Mother earth! saves resources...reduces waste....reduces fuel consumption from making things from scratch.   I live in San Diego and I put my recycles out for the homeless, so that they can empower themselves and in inproving their situation.... It is better than giving money to a begger.

to maximize surface area for the collection of sunlight and minimize weight and material used. also, yes it helps transport water and nutrients.

While I have very very strong opinions on Bush's political agenda of robbing from the masses to give to his ultrarich handlers, I think it's best to focus on the technical side of your question regarding fluorescent bulbs verses incandescent bulbs.  Fluorescent bulbs (and yes, that's spelled right...lol) are four to six times as energy efficient as incandescent ones.  Meaning, for example, that a 15 watt Fl bulb produces as much light (in lumens) as a 60 watt Inc bulb.\n\nOk, great...we save three fourths of the energy...sounds good, right?  Sure...but it's not gonna happen.\n\nMany people won't switch because of up-front costs.  To replace all the light bulbs in your house would be a very very expensive feat.  Yes, it would save you a lot in the long run, but most of us just don't have that kind of investment money.  Another factor is that fluorescent light and incandescent light just isn't the same spectrum.  Most of us, in our own homes, prefer the warmer light provided by incandescent.  Think about how sterile a doctor's office, or a walmart, or an office, feels.  Not the way we want our homes to feel most of the time.  Switching may be smart money in the long run, but it's not really what most people would do given the choice.\n\nIf, by the way, you want to save massive amounts of energy...the way to do it would be to weather-strip every house in America...that's cheap to do and EVERYONE would like the result in their house!

Some lights are on a timer to save electricity.

:] \nThere is light that we may work\nToday is the day of salvation

If you use the mini fairy type of outside lights the cost will be minimal. Probably no more than 2-3 dollars for the next month. Get creative! Do some large bushes or small trees! Have a Great holiday! ;-)=

a light that makes you glow in the dark, buy it at any hardware store\n\n:> peace\n.

That depends.  I need a little more info.  Are they common area lights?  Does anyone else benefit from them?  Usually the answer is no he can't.

Daylight saving time or daylight savings time (DST) is a widely used system of adjusting the official local time forward, usually one hour from its official standard time for the duration of the spring and summer months. This is intended to provide a better match between the hours of daylight and the active hours of work and school. The "savings" are spent on evening activities which get more daylight, rather than being "wasted" while people sleep past dawn.\n\nDST is most commonly used in temperate regions, due to the considerable variation in the amount of daylight versus darkness across the seasons in those regions.\n\nGovernments often tout it as an energy conservation measure, on the grounds that it allows more effecive use of natural sunlight resource in summer time. (People go to bed and wake up earlier, which reduces use of electric lights.) Some opponents reject this argument (see below, Criticism).\n\nEuropeans commonly refer to the system as summer time: Irish Summer Time, British Summer Time, and European Summer Time. This is reflected in the time zones names as well, e.g. Central European Time (CET) becomes Central European Summer Time (CEST).\n\nNote that the term commonly used in the United States, daylight savings time, has been criticized by some commentators as being incorrect, for both historic (the name as provided by the act which inaugurated it in the United States is daylight saving time) and grammatical reasons.

Governments actually decide that it's a good idea for their community. The idea is, that if you change the time in certain parts of the year, then people will have more daylight during the times of the day that people are typically up, and it will get dark typically when people usually go to sleep.\n\nThe reason this isn't constant is becuase the world tilts consistently every year as it circles the sun.

Savings = (Cost Conventional) - (Cost Efficient)\n\n(Cost Conventional) = (Energy Cost + Bulb Cost) x Period\n(Cost Efficient) = (Energy Cost + Bulb Cost) x Period\n\nConventional: 100 W * 0.08  $/kWh * 10000 h = 80.00\nOver the same period, number of bulbs = 10000/750 = 13.3\nSo, total cost = 80.00 + (14 * 0.42) = 85.88 (we can't buy a third of a bulb!)\n\nEfficient: 28 W * 0.08 $/kWh * 10000 h = 22.40\nNumber of bulbs = 10000/10000 = 1\nSo total cost = 22.40 + (1 * 17.00) = 39.40\n\nSavings = 85.88 - 39.40 = $ 46.48 (over a 10000 hour span).

yes\nit is designed so you can enjoy more sunlight durnig the day and also that you arent woken up by the sunrise before 5 am!\nits definetly a practical institution
