The Switch to Outdoor LED Lighting Has Completely Backfired

To reduce energy consumption, many jurisdictions around the world are transitioning to outdoor LED lighting. But as new research shows, this solid-state solution hasn’t yielded the expected energy savings, and potentially worse, it’s resulted in more light pollution than ever before.

Using satellite-based sensors, an international team of scientists sought to understand if our planet’s surface is getting brighter or darker at night, and to determine if LEDs are saving energy at the global scale. With the introduction of solid-state lighting—such as LEDs, OLEDs, and PLEDs—it was thought (and hoped) that the transition to it from conventional lighting—like electrical filaments, gas, and plasma—would result in big energy savings. According to the latest research, however, the use of LEDs has resulted in a “rebound” effect whereby many jurisdictions have opted to use even more light owing to the associated energy savings.

Indeed, as the new results show, the amount of outdoor lighting around the world has increased during the past several years. “As a result, the world has experienced widespread ‘loss of the night,’ with half of Europe and a quarter of North America experiencing substantially modified light-dark cycles,” write the researchers in the new study, which was published today in Scientific Advances.

When are people going to stop listening to these scammer "scientists". They were all wrong about LED lighting, just like they are all wrong about "global warming".

My issue some LED lighting are simply too bright, (the while/blue ones).

The advantage is if used properly can replace those awful yellow street lights.

You know, this reminds me of the Energy-Saver/Frost-Free setting on a household refridgerator.  That is controlled by a switch inside that turns on or off a heating element that spans around parts of the perimeter of the door and around the inside.  Most probably wouldn't see the value in having some heat, unless you take into consideration the example of a frost-free setting on a refridgerator. 

Or think about all the outdoor lighting which could get snow packed into it during a blizard.  Say for instance snow gets packed into traffic lights during a blizzard, that has actually happened with newer LED lights.  Then they are not thawing out and the traffic light gets blocked.  So should traffic lights also have a heating element, in addition to the dropping resistor in the base of the LED bulb (which in some cases seems to be an insufficient source of heat to thaw out the snow)?

Then there are some benefits to having less heat, such in small recessed lighting fixtures, small rooms, etc.

I like the color of the ordinary halogen/incandescent lighting in my indoors living areas.  So only in the most unusual lighting fixtures do I have LED lighting.  These include small recessed fixtures above the stove and above the kitchen sink, where traditional bulbs would overheat and prematurely burn out.  I do have fluorescent lighting in my shop area, though I don't bother at all with CCFLs.

The halogen lights around the house almost all have dimmer switches (either on the lamps or on the walls) which I use to knock off the top 5%  to 10%.  This can be used to get a nice pleasant orangish-redish glow which is not really possible with other technologies.  Also dimming any incandescent bulb by just a small amount will increase the life of the bulb dramatically.  A good analogy to that is that hard service incandescent bulbs, such as those used in conventional traffic lights, are actually 130 volt bulbs.  Since they operate on 120 volts, they never reach their rated power.  That helps them to last much longer.

Also there is a new technology being developed by scientists right now, outside of LED, fluourescent, and incandescent (tungsten and halogen) which I have read about.  It is a reimagination of the incandescent bulb:
Return of incandescent light bulbs as MIT makes them more efficient than LEDs
http://www.telegraph.co.uk/science/2016/03/12/return-of-incandescent-light-bulbs-as-mit-makes-them-more-effici/
These will have the aesthetics of a conventional incandescent (tungsten or halogen) bulb.  If they can make this work, and at an affordable price to the consumer, then I think this is the way to go.

Mysterious loud booms are being heard around the world and no one knows why

Something very strange is going on, and it seems to be happening all around our planet. Reports continue to emerge of booming sounds of mysterious origin echoing from the sky, from Colorado and Alabama to the Middle East, United Kingdom and Australia, according to News Corp Australia.

The sounds, understandably startling for those who hear them, are certainly not the voices of gods, although their source has thus far defied scientific explanation as well.

A recent example occurred in Alabama, when a thunderous noise shook houses and frightened residents on Nov. 20. Not long after, explosion-like sounds were also heard in Colorado, although officials now believe that the Colorado clamor was unrelated to the worldwide phenomenon, likely caused by oil and gas extraction.

Other booms around the world, like the one in Alabama, remain unexplained. Locals in Cairns, Australia, were shaken by a loud rumble on Oct. 10. Then two weeks later, another boom was heard over the Eyre Peninsula in South Australia.

**********************************************

it must be Earth telling scientists to go vegan and use less LED lights.

This wouldn't fall under the catagory "Stupid" but "unexplained / mystery"

Earthquake Booms, Seneca Guns, and Other Sounds.

They talked about this mystery for quite some time, the recent episode of the "Unexplained Files.

Bitter cold and snow threatening parts of eastern US

Winterlike conditions are expected to wallop the eastern half of the country, from Denver to New York City, as a significant change in the weather pattern takes shape.

A major storm is developing in the middle of the country with heavy snow, strong winds and thunderstorms, according to ABC News meteorologists.

More than a dozen states, from the Rockies to the Northeast, have issued winter weather warnings or watches.

The storm system is moving out of the Rockies into the Plains this morning with snow, wind and rain. A line of strong storms with lightning, gusty winds and heavy rain will reach Chicago this evening, meteorologists said.

Cold weather in December is definite proof that the theory of global

warming is not true. What a sophisticated scientific argument.

Think I'll post this here instead of "From Around The Galaxy" thread. Just heard for the first time on Science Channels, "How the Universe Works - Are Black Holes Real?"

Black Holes May Have Hair:wacko:

Why did you think this deserved to be in the "Stupid Science" thread? Did you read the articles?

Yes I've read it and on the Science Channel, they showed a black hole as a ball of hair.  Hair....really - can't they use a better terminology? Scientist are now asking, do Black Holes exist at all?

You saw then that the "hair" is just a semi-humorous term used by physicists to describe that, instead of black holes potentially being "smooth", with the gravity well dragging everything in a uniform wave into the center, that there now appears to be "hairs" of energy (?) around the edges. It sounds goofy to say "hair" but it's just a nickname for a theoretical phenomenon. If or when it's proven, they may come up with an official terminology for it.

I thought that black holes had been proven in the last decade. I guess up until we can send a probe of some sort into one, they will continue to be theoretical to a certain degree.

WEATHER WARNING: Hurricane season to be more DEADLY than 2017 thanks to climate change

HURRICANE season this year could be even more devastating than in the past as climate change is making the deadly storms even stronger, researchers have warned.

New research has found due to warming oceans, storms are building up quicker and in return are releasing faster and with a much stronger force.

Hurricanes are fuelled by heat and in 2017 temperatures in the western Gulf of Mexico reached record highs before the deadly Hurricane Harvey struck in late August.

Research published in Earth’s Future found the energy released into the atmosphere during the rainfall of Hurricane Harvey matched the amount of energy removed from the ocean.

Hurricane Harvey dumped an astonishing 60 inches of rainfall in parts of Texas which is the highest on record for a single storm in the history of the United States.

*************************************************

It's the same lies with these people every year, I hope nobody is stupid enough to believe them.
