Is Solar, LED’s or CFL’s energy going to be the energy of the world or is it even worth it to the environment.
Everyone is in the crave of having a solar panel on the roof in their backyard on a large filled to make electricity, yes the theory is a good idea the sun powers solar system in a power goes to the battery to store or to a products like a light bulb or to charge your phone or even to run your refrigerator. Solar will reduce your electric bill and is more environment friendly as far as producing power. So if you produce over 100 megawatts solar power you can power over hundred thousand homes that is a great idea. So that particular sewer system would take a strain off our grid system. That of course is over 80 years old; it was only mate to be for 30 or 50 years before being changed out. But as the population got bigger and bigger the power companies had all the resources out building new grid systems. They are stretching the power grid further out to more buildings and houses on our strained system. So the older parts of the grid system have been repaired in some instances have been ignored of needing to be completely replaced. Of course it would take trillions of dollars to upgrade all of our grid systems. Money you and I would have to pay thru raising energy cost or taxies. Our government and utility companies do not have the money to do that, so were trying very hard to reduce the strain on our electric grid system.
Of course just like the CFL’s you know what those are the twisty type of light bulbs that the government wanted you to put into your homes even though Britain and Canada and other countries have banned them from their country. Because they have bad energy waves and also under certain lighting conditions they would even hurt your eyesight. But our government still pushed the use of the CFL’s and every home, business and offices. Knowing the danger the CFL’s light bulb has. If you would Google the dangers of CFL’s you would find a list of documents, videos and articles on why you should not use the CFL’s light bulb.
Just like to CFL’s a solar panels have a dangerous side to 100 MW solar power system that could power over 100,000 homes and how good it would be for the power companies and the end-users. On the same solar system it has a very dark side to it. It produces over 100,000,000 tons of hazardous waste to manufacture of the solar panel. Another question is where do we store, all of that waste? Of course we store it underground in storage facilities. Where the companies put it, is the same ground that our lives depend on, for growing our food to the animals and trees that give us life. The environment is in bad shape, whether or not you believe in the science behind the studies of our environment. We know the trees give us oxygen to breath and the tree depend on the ground to grow. Without oxygen we can breathe, so inadvertently we are destroying our lives as we know it, instead of getting up in the morning and going outside and have a cup of coffee and enjoining the birds singing in a tree. If we keep going the only view you will have is threw a glass window. If you wanted to go outside, you first have to get up and put on oxygen tank with a mask to go outside. You mint even have to wear a chemical suit depending on the atmosphere. That is not a world that I think, we should leave our children. So think about it, are solar panels to power energy for the next-generation and is it worth it?
So basically solar panels, LED’s and the CFL’s can and will reduce the consumption of energy that we are using, but it is not the safest manner to do so. LEDs even produce amount of lead, a known neurotoxin, the low-intensity red LEDs has the most hazardous waste. We are so worried about saving energy and help reduce the stain on our grid system. That we are forgetting once again what happens to the environment.
Safety is everything in Parking lots are often the first step for your customers or visitors when they arrive at your establishment. With that being said. Parking lots are often overlooked when it comes to general upkeep and overall appearance.
One of the easiest and most cost efficient ways to enhance safety and give your parking lot a facelift is to improve its lighting.
For years, outdoor parking areas have been illuminated by High-intensity discharge (HID) fixtures. In recent years, there has been a rapidly growing trend to switch out these old HID fixtures with new LED fixtures.
The reason for this change is to due the many downfalls of HID. The glaring issues being that HID is not aesthetically pleasing, they consume a significant amount of power. Their overall light quality is low, and they’re very expensive to maintain.
On the other hand, LED parking lot lights consume significantly less power, require zero maintenance. And they provide an overall better quality of light. Which makes them the best alternative to HID fixtures.
Outdoor LED fixtures, such as canopy lights, wall packs, area lights, flood lights, and dusk to dawn lights can last up to 90,000 hours longer than HID. LED Parking Lot lights consume up to 90% less power than HID fixtures. Meaning that your typical payback period is less than two years!
The light that a HID Fixture produces can range from natural white color to orange Image result depending on the type of bulb. You’re using. HID fixtures also tend to have a low color-rendering index (CRI). Which is a quantitative measure of the ability of a light source to reveal the colors. Of various objects faithfully in comparison with an ideal or natural light source. The CRI for a HID bulb can range anywhere from 0 to 65. Lastly, HID fixtures emit light that is multidirectional and it is often wasted on undesired areas. LED Parking Lot Lights are designed to be night sky friendly, which does not waste any light.
Throughout their entire lifetime, LED parking lot light fixtures maintain the same natural white or cool white color. LED fixtures are also capable of having CRIs of 80 and higher. Lights with a CRI of 80 or higher are considered to show colors most accurately and increase visibility. A higher CRI in parking lot light fixtures is key to your properties security and safety. In addition, LED fixtures are able to deliver focused light, night sky friendly with less glare to ensure that you’re lighting desired areas.
In conclusion, the best and most cost efficient way to upgrade your parking lot is to replace your HID parking lot lights with new LED parking lot light fixtures. The benefits of making the switch to LED include energy savings, minimal maintenance, life longevity, safety, brightness and color quality. These benefits alone outweigh the upfront cost it would take to buy and install new LED fixtures in your parking lot.
Our future is tearing apart, we are polluting our planet and don’t even care.
We got big oil companies that are leaking oil every day in the Gulf of Mexico.
But yet in our general lives we cut our grass and plant flowers. We make our yards look fantastic for everyone to admire.
But if somebody to throw trash on it or throw oil on our grass we would be up in arms and calling the cops or beating them up or crucified them on social media.
If you want to know who the people are in your neighborhood who cares look down the road on recycling day. If your city or county have a recycle program and you can see the ones that put out the bins to get picked up for recycling and those are the people who really care about the planet.
We all live on this world, we all would recycle. Recycling is not the finale solution but it is a start.
But yet we allow people to pollute our Earth and make it to where we will never be able to live as we do now. So what’s the problem do we treat our homes better than our world of course some of us do. but that is not the Legacy that I want to leave.
We have to come up with a better solution to treat our world and make our future brighter.
Grant you some people don’t even care about their house or yard. it’s trash all over the yard, junk cars everywhere leaking oil and gas. If you don’t have self-pride how can you even have pride of where you live or our planet.
But for the most part people treat their homes like castles so we need to treat our planets like it’s our home.
What are we teaching our children? Don’t forget our children are byproducts of ourselves so what they learn is what they see and what we teacher.
We need to stop and look around and take action, speaks out. Actions speak louder than words. we need to step up and show that we are better than that.
But again, you just can’t sweep a corner of a floor and call the whole floor clean.
You have to clean the whole earth in order for it to work to not pollute our Earth.
If you really want to look at things think about your home and how well you keep it clean and neat and tidy. How well your yard is kept? That is how we should treat our Earth. So that we can continue to live here. And not have to sort to drastic measures in order to even live.
We are not working fast enough to educate our kids and adults about taking care of our world and not pollute our Earth. We should make stronger law that protect our world. If the EPA had authority as a cop does, we would improve our world a lot.
Let’s hope we wake up and do what’s wright for our world before it’s too late.
A significant scientific report issued by 13 federal companies on Friday presents the starkest warnings. The implications of local weather change for the US Global Warming,
Predicting that if vital steps will not be taken to rein in international warming. The harm will knock as a lot as 10 % off the scale of the American economic system by century’s finish.
The report, which was mandated by Congress and made public by the White Home. Is notable not just for the precision of its calculations and bluntness of its conclusions. But in addition as a result of its findings are instantly at odds with President Trump’s agenda of environmental deregulation. Which he asserts will spur financial development.
Mr. Trump has taken aggressive steps to permit extra planet-warming air pollution. From car tailpipes and energy plant smokestacks, and has vowed to pull the USA out of the Paris Settlement. Below which practically each nation on the earth pledged to chop carbon emissions. Simply this week, he mocked the science of local weather change due to a chilly snap within the Northeast, tweeting, “No matter occurred to US Global Warming?”
However in direct language, the 1,656-page evaluation lays out the devastating results of a altering local weather. On the economic system, well being and surroundings. Together with report wildfires in California, crop failures within the Midwest and crumbling infrastructure within the South. Going ahead, American exports and provide chains might be disrupted, agricultural yields may fall. To 1980s ranges by midcentury and hearth season may unfold to the Southeast, the report finds.
“There’s a weird distinction between this report, which is being launched by this administration. This administration’s personal insurance policies,” assist Philip B. Duffy, president of the Woods Gap Analysis Middle.
All advised, the report says, local weather change may slash as much as a tenth of gross home product by 2100.
Greater than double the losses of the Nice Recession a decade in the past.
Scientists who labored on the report mentioned it didn’t seem that administration officers. Had tried to change or suppress its findings.
Nevertheless, a number of famous that the timing of its launch, at 2 p.m. the day after Thanksgiving. Appeared designed to reduce its public influence.
Nonetheless, the report may change into a strong authorized instrument for opponents of Mr. Trump’s efforts to dismantle local weather change coverage, specialists mentioned.
“This report will weaken the Trump administration’s authorized case for undoing local weather change laws
And it strengthens the arms of those that go to courtroom to struggle them,” mentioned Michael Oppenheimer. A professor of geosciences and worldwide affairs at Princeton.
The report is the second quantity of the Nationwide Local weather Evaluation, which the federal authorities is required
by legislation to supply each 4 years. The primary quantity was issued by the White Home final 12 months.
The earlier report on US Global Warming , issued in Might 2014, concluded with practically as a lot scientific certainty, however not as a lot precision on the financial prices. That the tangible impacts of local weather change had already began to trigger harm throughout the nation. It cited growing water shortage in dry areas, torrential downpours in moist areas and extra extreme warmth waves and wildfires.
The outcomes of the 2014 report helped inform the Obama administration because it wrote a set of landmark local weather change laws.
The next 12 months, the E.P.A. finalized President Barack Obama’s signature local weather change coverage.
Referred to as the Clear Energy Plan. Which aimed to slash planet-warming emissions from coal-fired energy vegetation. On the finish of the 2015, Mr. Obama performed a lead function in brokering the Paris Settlement.
However in 2016, Republicans typically and Mr. Trump particularly campaigned in opposition to these laws.
In rallies earlier than cheering coal miners, Mr. Trump vowed to finish what he referred to as Mr. Obama’s “warfare on coal” and to withdraw from the Paris deal.
Since successful the election, his administration has moved decisively to roll again environmental laws.
The report places essentially the most exact worth tags so far on the associated fee to the USA economic system of projected local weather impacts. A $141 billion from heat-related deaths, $118 billion from sea stage rise and $32 billion from infrastructure harm by the top of the century and amongst others.
The findings come a month after the Intergovernmental Panel on Local weather Change, a bunch of scientists convened by the United Nations, issued its most alarming and particular report back to date in regards to the extreme financial and humanitarian crises anticipated to hit the world by 2040.
However the brand new report additionally emphasizes that the outcomes rely upon how swiftly and decisively the USA and different nations take motion to mitigate international warming. The authors put forth three important options to place a worth on greenhouse gasoline emissions. Which often means imposing taxes or charges on corporations. That launch carbon dioxide into the ambiance. Establishing authorities laws on how a lot greenhouse air pollution could be emitted and spending public cash on clean-energy analysis.
A White Home assertion mentioned the report, which was began below the Obama administration, was “largely primarily based on essentially the most excessive situation” of world warming and that the subsequent evaluation would supply a chance for larger steadiness.
The report covers each area of the USA. Asserts that current climate-related occasions are indicators of issues to return.
No space of the nation can be untouched, from the Southwest. The place droughts will curb hydropower and tax already restricted water provides, to Alaska. The place the lack of sea ice will trigger coastal flooding and erosion and power communities to relocate. To Puerto Rico and the Virgin Islands. The place saltwater will taint consuming water.
Extra folks will die as warmth waves change into extra frequent, the scientists say, and a warmer local weather will even result in extra outbreaks of illness.
The two areas of influence significantly that stand out are the commerce and agriculture.
Local weather change is taking the USA into uncharted territory, the report concludes that US Global Warming.
“The belief that present and future local weather circumstances will resemble the current previous is now not legitimate,” it says.
There’s all the time some uncertainty in local weather projections, but however scientists’ estimates in regards to the results of world warming so far have largely been borne out.
The variable going ahead, the report says, and is the quantity of carbon emissions people produce.
With a global warming report comes and other reports of big manufacturer shutting down plants eventually everything that is manufacturer. Is going to be done by automation. So we headed out pink slips to everybody and say you don’t have a job anymore. But instead we should hand them a green slip. Give them the education and the training to help our world. That will refuel the economy. instead of closing towns or closing a mom-and-pop stores. We should retrain or Workforce for the next generation of workers.
You do not read or hear about studies walling out of class in the USA for climate change. But in Australian they are walking out for climate change. We should do the same because climate change affects all of us. This is the story..
The College Strike four Local weather has gained momentum in latest weeks. With almost thirty occasions being organised in capital cities and regional areas round Australia.
This November 30, 2018 together with a whole lot probably 1000’s of highschool college students. Can be collaborating in a pupil strike for local weather motion.
Initiated by the Australian Youth Local weather Coalition, the College Strike four Local weather. Has gained momentum in latest weeks, with almost thirty occasions being organised in capital cities and regional areas round Australia.
We’re presently dealing with an unprecedented local weather emergency. With 2018 being the most well liked 12 months on report, we face the prospect of an unsure and harmful future.
Local weather change is threatening water safety. In accordance with the Local weather Council’s newest report, and exacerbating droughts and wildfires internationally. The Intergovernmental Panel on Local weather Change report makes it clear. Revolutionary change it required to take care of the impending climate disaster.
But, the Coalition and Labor’s unashamed love of coal has rendered the key events’ responses cowardly.
Whereas Prime Minister Scott Morrison waves round a lump of coal in parliament. Talks about rising the function of coal throughout the vitality combine, Victorian Labor planning minister Richard Wynne is fast-tracking approval for brand new coal to hydrogen tasks.
One of many causes we’re hanging is inaction. Inaction on the a part of governments has seen the biggest existential menace within the coming a long time be ignored.
It has led to a scenario the place highschool college students those with the least energy in society are having to carry these with probably the most energy to account.
We might not be notably highly effective, however we do have a voice. Collectively, when enormous numbers of us are marching in collective solidarity. We the facility to encourage an entire new technology of younger leaders to take curiosity of their communities and futures.
We additionally recognise why local weather change has develop into the disaster that it’s.
Below an financial system that prioritizes income above all else, it’s no shock that the pursuits of the planet and folks come second. Below capitalism, the surroundings is simply one other commodity for these in search of to additional their already massive wealth.
We all know that local weather change hurts the poor and dealing class probably the most. With greater than 1/3 of the planet not fertile sufficient to develop meals. Accordance with Mercy Crops, folks in poor international locations are more and more having their livelihoods stripped from them.
We additionally know that it’s the wealthy and highly effective that we’re concentrating on: 70% of worldwide air pollution is brought on by the world’s 100 largest firms. We’re hanging to ship them a message.
Since most of us are denied the correct to vote for the politicians ruining our futures, we’re taking to the streets to march, chant and demand change.
That’s as a result of when planet Earth is below assault, we arise and struggle again.
About a month ago scientist gave the report about global warming. Hopefully we take their advice and reverse global warming. The students in Australia have a fantastic idea. Nationwide or Earth wide we should say we all need to strike and protest that nobody is doing enough about global warming. We need to take the young people and get them more and more involved in global warming. That way they will have a brighter future.
Global warming on earth everybody has heard of it some people pay attention to energy-efficient. They do their part by recycling and using energy-efficient appliances or finding new ways to heat and cool your home. Some Go Solar so they can cut to utility cost. But no matter what the small percentage of the people who do all these stuff to help environment Earth Needs Your Help.
It really isn’t going to matter because we have a majority of the people who don’t care or they ignore energy-efficient. They keep throwing trash on the ground they keep on with their lives as if nothing is going on. What they going to do if we don’t stand up as a nation United to combat global warming. We will all suffer think about it, look at the dinosaurs.
Do we want to become like the dinosaurs extinct. I do not, I don’t want my kids or their kids too have that kind of future or possibility of a future.
Circle of Life
Look at Florida for example the red tie and a green sludge and is going on in the state that is all caused by Man. By chemicals that we put on the ground. It ends up into our water and eventually ends up into the sea. Which ends up killing a lot of our animals. Look at the animal population over the decades. We have Hunted, poached, poisoned or just right out killed them off. We leave them on the side of the road. We’re running out of animals populations of tens and thousands and went to hundreds.
If you believe in thecircle of life from the smallest animal to the biggest animal or mammal it all has a purpose. If we break the circle of life then we break down an environment. At the same time the purpose of the animal or micro ism breaks down and they can do their job. Every animal has a job to do. So therefore we enter fair with a circle of life. By doing that we help global warming to grow.
So where will we live? What would we do if it gets so hot or the air is so polluted that you can’t even go outside. Are we going to invest in cities that are completely indoors. Where nobody goes out to the real world walks Trails or climbs mountains or fishes in the rivers.
We’re going to come people of glass dooms. I hope not because we have a lot of beautiful scenery out here in our world from China to the US to Alaska to Asia. That we can go and see. But soon if scientists are correct which science is just a theory but back by studies and data. We don’t have to chance in the next 10 years.
That is not a lot of time to reverse everything that we have done. Plus when we all Stand Together and do this no more to shellfish and governments standing in our way. Maybe we can , make it better. But we have too many people who just don’t care. So the small percentage of people who do I give two thumbs up to and keep up the stride to make our world a better place.
In my hometown, like many others, modified to HPS streetlights fixtures as a result. Of they had been extra power environment friendly than their predecessors.
The brand new fixtures solely appeared within the industrial downtown district. I keep in mind the eerie orange glow that we may see trying in that route from our neighborhood.
The response was common: these lights had been ugly. Once I began driving around. I noticed that most of the lights weren’t simply unattractive, they had been additionally ineffective.
I did not know something about color rendering index or color temperatures. However I knew that it was troublesome to see, regardless of how vivid the lights had been.
Here is a comparability picture exhibiting the orange glow of an HPS mild in comparison with the pure daylight offered by an LED fixture.
Any Coloration You Like
LED bulbs are available quite a lot of color temperatures. Usually within the 2700K (heat) to 5000K (cool/daylight) vary, permitting shoppers to pick probably the most applicable mild for the job.
Heat lighting tends to be extra pleasing to the attention, whereas cool/daylight offers higher workspace illumination.
KC is an east coast city with a historic neighborhood really feel, and the residents wish to maintain the welcoming ambiance of their road lighting.
On the identical time, its essential thoroughfares and industrial parking tons can benefit from lighting. That is nearer to pure daylight, which might not be splendid for neighborhoods.
Township lighting designers selected luminaires that strike a stability between aesthetics and efficiency.
The three completely different lighting fixtures chosen for this challenge – one for neighborhoods. One other for parking tons, and a 3rd for main roadways.
Deliver greater than 100 lumens per watt with a 90% energy issue and a good color rendering index (CRI) of not less than 70.
Tax Saving for the City
Saving taxpayer by the usage of environmentally-friendly expertise is a win-win for the city and residents.
The brand new LED luminaires generate vital power financial savings that present unprecedented environmental. And financial advantages to our city and residents.
Resulting from this success of our road lighting improve to LED expertise. City of KC will quickly convert a further 4,000 indoor luminaires, yielding additional financial savings to taxpayers of $200,000 over ten years.
The lighting funding can pay for itself in lower than three years by saving $3M per 12 months in power prices.
Over the anticipated lifetime of the luminaires, the township expects to save lots of $57M in power and upkeep prices.
Moreover the monetary profit, the brand new fixtures additionally present higher visibility, improved aesthetics, and superior color rendering.
Cities all over the world have gotten enlightened about power effectivity and value financial savings. To see quite a lot of case research, try the Division of Power’s web page of demonstration tasks.
In June 2016, the American Medical Affiliation printed a set of pointers to assist lighting designers select lights that maximize effectiveness and effectivity without inflicting hurt to dwelling organisms.
After a current article about LED streetlights, I fielded just a few questions in regards to the attainable opposed results of LED lighting.
I knew that the AMA report cited lights with a heavy blue content material, like “cool white” lights with shade temperatures above 4000 Ok, however I used to be unaware of the subtleties within the shade spectrum related to lights. Not too long ago, the US Division of Power – which nonetheless exists on the time of this writing. Printed a really enlightening 18-page doc that covers the problem intimately in lighting designers. This is a synopsis of that report.
What Is “White” Mild?
All of us discovered at school that white gentle is a mix of all the colours of the rainbow. Just like the solar, all synthetic gentle sources – incandescent, fluorescent, high-intensity discharge, and
LED – produce a broad spectrum of sunshine with varied ranges of every shade. However the colours merely characterize our aware notion of the sunshine that we see.
Mild is an electromagnetic wave, with totally different wavelengths of sunshine showing as varied colours to our visible receptors.
As you may see within the desk, every shade spans a variety of wavelengths. What we name “blue” is any gentle wave whose wavelength is between 450 and 490 nanometers.
Even the vary boundaries fluctuate relying on which physics textbook you are consulting.
Color Temperature Is an Approximation
Most gentle bulbs are designed to emit white gentle, however there’s a couple of form of white. For instance, cool white bulbs are usually heavier on the blue aspect of the spectrum,
whereas heat white bulbs lean towards, fluorescent the pink aspect. We regularly use the time period “correlated shade temperature” (CCT) to characterize every shade with a quantity.
In keeping with the DoE report, “CCT is expressed in kelvin (K). The worth corresponds to the color of sunshine emitted by a heated mass (a theoretical blackbody radiator). At that bodily temperature (though the sunshine supply will not be really working at that bodily temperature).
So an LED with a CCT of 3000 K will seem to provide off a shade of sunshine near that of a tungsten filament operated. At a bodily temperature of 3000 K (tungsten being very near an excellent fluorescent radiator).”
The issue with CCT as a metric is that it does not convey sufficient data as a result of a shade can be a mix of many wavelengths.
When scientists break gentle into its part wavelengths, they produce a spectral energy distribution. A graphical illustration of the totally different wavelengths of sunshine and the depth of every wavelength.
Under you see the spectral energy distributions for 3 totally different gentle sources.
Well being and Environmental Issues
Initially, there’s nothing inherently harmful about any gentle within the seen spectrum, so long as the depth is not too excessive. (Daylight is protected, however do not look instantly on the solar.)
The problems with synthetic lighting have extra to do with affecting an organism’s circadian rhythms. The pure cycles that inform our our bodies when to sleep.
Mild that leans towards the blue finish of the spectrum is much like the pure daylight that we might see round noon.
That is the time once we’re alleged to be best, so our our bodies react to that gentle by being alert.
Nighttime publicity, nevertheless, can result in sleep issues, and therein lies the well being concern. It must be famous that the identical concern exists for pc, pill, and smart phone shows.
Flip off your units at evening and get some sleep.
The eyes have receptors that detect totally different colours. Scientists have lately found receptors that have an effect on the mind exterior the visible cortex. In different phrases, they detect gentle however that gentle will not be perceived visually.
Proof means that these receptors, whose sensitivity peaks at gentle ranges round 480 nm (the excessive aspect of blue). Might have an effect on circadian rhythms.
Why Not Go With Hotter Colours?
Since LEDs will be designed to emit nearly any shade spectrum. It appears logical to easily design them to emit hotter colours that reduce the blue finish of the spectrum. Nevertheless, cooler colours have a tendency to supply sharper pictures.
In different phrases, it is simpler to see in gentle that is extra on the blue aspect. Cool LEDs additionally are usually extra environment friendly, in order that they use much less energy for a similar quantity of sunshine.
LED Design Options
Advances in LED expertise can convey us one of the best of each worlds: efficient lighting without the well being points.
LEDs will be tuned to emit specific wavelengths, permitting engineers to design lighting techniques that produce cool gentle whereas minimizing the slim vary of wavelengths that have an effect on sleep cycles.
Since cool lighting is simpler, lights do not have to be as vivid. In actual fact, streetlights will be dimmed late at evening to avoid wasting power and cut back the affect on fluorescent circadian rhythms. Cambridge, MA dims its streetlights after midnight, with no complaints from residents.
Do not Concern the LED
Whereas considerations about LED streetlights are considerably legitimate, you needn’t fear about them turning you right into a sleep-deprived zombie. (That is what your smart phone is for.) With correct consideration to a light-weight spectral energy lighting designers distribution and brightness controls, engineers have the data and instruments to design lighting that is protected, efficient, and power environment friendly not fluorescent. Rating one other level for science!
