Efficient New Light Bulbs
Introduction
When Thomas Edison invented the light bulb in the late 1800’s people were too amazed by the fact that they could effectively light up the night to bother considering how much energy was required.1 As time has marched forward, the priorities and desires of mankind have evolved. With growing concerns over world energy reserves and power production, many around the world have searched for ways to reduce energy consumption. One of the explored ideas was the LED light bulb. Consuming far less energy than a traditional light bulb while enduring a longer period before expiring, the LED light bulb is an ideal replacement of the traditional bulb in regards to the preservation of energy. Another lighting idea that panned out was the florescent light bulb. These bulbs employ a different method of light production when compared to LED lights, but they have similar results of energy cost reduction and longevity. It may seem like a small thing to reduce the power consumed by a light bulb, but when all of the lights of the world are converted the benefits will add up to be something worth investing in.
The Inner Workings of Fluorescent Light Bulbs
In order to understand why Fluorescent and LED light bulbs are a more efficient choice it is important to first understand the basic concept of the tradition or incandescent light bulb. An incandescent light bulb uses a thin tungsten filament contained within a glass container. When an electrical current is run through the filament the filament resists the electrical current. The resistance of the tungsten filament against the electrical current transforms the electrical energy into heat, which makes the filament white hot and in turn makes it glow, producing ...

...dwide will decrease significantly. This decrease in energy demand allows for a decrease in the reliance on fossil fuel based power plants, which means there will also be a reduction in greenhouse gas emissions. All things considered, there is no reason to delay the conversion from the old inefficient bulbs to the new efficient bulbs.

According to the National Bureau of Economic Research, DST increases overall energy consumption by “approximately 1 percent” (Kotchen) and rises to 2-4 percent in the fall. The use of air conditioning, television, lighting, and other appliances causes the residential energy demand to
The light bulb is the way we see in the dark, the way we find our way, the way we know when to go at a stoplight. How did Thomas Edison achieve this invention? Knowledge. Knowledge of electricity and the needs of those around him. In The Great Gatsby, Daisy Buchanan claims that she wants her daughter to be “a beautiful little fool.” In other words Daisy is saying that ignorance is bliss. Some others believe that knowledge is power. The advancement from candles to light bulbs changed the culture entirely. People could easily do the work they needed to after sunset, and it even led to more inventions. We need knowledge to advance, and for this reason powerful knowledge is more valid than blissful ignorance.
The light bulb changed how we lived now. Thomas Edison invented the light bulb, as he grew up he was learning so much knowledge for chemistry and electronics, and his 40 years of research to get the light bulb to work. Thomas Edison is an inventor of major technology. Threw his years he had studied many books by his parents and been reading many books on chemistry and electricity. The more he grew up he started to pursue his education on chemistry and electronics for many years. The more he tried to invent things he had help making of the light bulb with a group of scientists. Thomas Edison is the one who made the light bulb become possible by pursuing more education.
Some of his inventions include the photograph, the motion picture the electrographic vote recorder, and his most famous invention the light bulb. Thomas edison started working on his igea of a light bulb in 1878. He envisioned it as a oil and gas based light that would be longlasting that could be used indoors instead of having to use the outdoor light. He based his ideas on other people's inventions such as Henry Woodward and Mathew Evans. He found that there were many flaws with where light sources and planned on creating a whole different approach to building his light build that would fix all on the problems. Thomas Edison light bulb consisted of a carbon filament. It took him many tries before he successfully tested his lightbulb which lasted thirteen and a half hours. His carbon light bulb became a patent on November 4, 1879. Even though the light bulb was already patent Thomas Edison still found more ways to improve it. He discovered that carbonized bamboo filament could last 1,200 hours, so Edison decided to form the Edison Electric Light Company where he could publicly sell his new light bulbs and have access to new supplies where he can improve and manufacture his carbon light bulbs. Thomas edison created a whole new way of access to working and living environments that impacted history in a great
A common argument made against standard time is that daylight savings time prevents road accidents because of the abundance of natural light at times that most people drive. However, is it worth it to disrupt the circadian rhythm so that drivers have more natural light? The governments have implemented lighted highways and roads and cars are equipped with headlights to aid in vision. While lighted highways consume energy, the claim that daylight savings time contributes to less energy consumption is contradicted by research efforts. Indiana did not adopt daylight savings time until 2006, thus making it the perfect environment for a study on the correlation of energy consumption and daylight savings time. According to Brian Handwerk, the “lighting demand dropped, but the warmer hour of extra daylight tacked onto each evening led to more air-conditioning use, which canceled out the gains from reduced lighting and then some.” Along with this study, researchers have argued that energy consumption may be lower in the evening, but consumption goes up in the dark mornings thus making the results equal. According to another study conducted by Hendrik Wolff, everywhere that has air conditioning takes a loss in regards to daylight savings time. In the long run, day light savings time does not have a significant impact on energy consumption thus being
on the automotive industry and with the population encouraging more fuel efficient and lower polluting transportation the future of the automotive industry will likely respond to those demands. The environment will likely become an increasing concern with the automotive industry. The effects of a change to a more environmentally friendly automotive industry are yet to be seen but I can assure you that all American households as well as the United States government and other countries will be watching.
There are a number of measures that have already been shown to have a positive effect on the environment and, if we redouble our efforts, could help to reverse the situation. I believe that, while it is true that there is a lot of negative news to this situation, there are many positive and effective actions that can be taken to restore a lot of what we have lost, or are in danger of losing. Consequently, a number of feasible measures can be implemented which will go a long way in slowing, stopping and, over time, reversing some of the harm caused. Initially, and perhaps the most important, is that we need to tackle the problem of carbons in our atmosphere. Consequently, if CO2 emissions are cut or drastically reduced, this will in turn help to reduce the level of greenhouse gases meaning that further global warming will diminish. (Climate Change Evidence and causes, 2013:33) This can be done in a number of ways. By continuing to develop new, greener technologies, cars and traffic in general will become cleaner, emitting fewer exhaust fumes and releasing less carbon into the air. This is already being done. At the recent UN climate-change conference in Doha, some 37 countries agreed to abide by legally-binding emission reduction measures. (Figureres C, 2012) We have seen the development of more efficient engines and hybrid models that use both petrol and electricity. Electric-only vehicles are also becoming more popular and new designs that are powered by solar energy are coming onto the market. Industry is also looking at ways to harness bio-mass and the possibility of hydrogen engines. These measures have already had a noticeable effect on the quality of life in a number of
In 2007, a study was done that showed that residents of Indiana paid $8.6 million more each year for energy, and that air pollution increased after the state switched to daylight savings time.
(Source C). The United States Department of transportation even stated that “the total electricity savings associated with daylight amounted to about 1 percent in spring and fall” (Source C). This statement is no more than a false fact. The national Bureau of economic Research conducted a study in 2008 stating that no real energy-saving has ever been recorded from daylight savings (Source F). Actually, the study found instead that “daylight saving time results in an overall increase in residential electricity demand.”
For new or retrofit construction, every choice can lead to energy savings; energy that is derived primarily from fossil fuels. The typical household LED replacement for a 60w light lasts about 50,000 hours. Pretending that an incandescent could also last that long, it would consume about 3,000 kilowatt-hours (kWh) of energy whereas the LE...
Before lights were placed on trees, candles were used instead. It is widely believed that Martin Luther, the 16th Century Protestant founder, first added candles to trees. He was walking home on a winter night while writing a sermon, when he saw the stars shining above the evergreen trees. He noticed how beautiful the view looked, and in order to recreate it for his family, he placed lighted candles on his family’s Christmas tree. An inventor named Edward Hibberd Johnson hired Thomas Edison, then a 24 year old inventor, who later created the lightbulb. After Thomas Edison patented the light bulb in 1880, Johnson invested money in Edison’s bulbs and later used them to fashion Christmas lights. He recognized that candles are a fire hazard, and lights would provide a safer alternative. Johnson wired 80 light bulbs of three colors and strung them around his tree. The beautiful, bright tree attracted newspaper reporters and pedestrians who continued to come back each year. In 1894, President Cleveland put lights on the White House tree for the first time. The first set of lights was released to the public in 1900 and priced at $12 or $350 in today’s money. In 1914, the sale price for a 16 ft string of lights decreased to $1.75. Today, 150 million light sets are sold, and 80 million homes are decorated each year which equates to 6% of the United State’s electrical load each
ways. The use of electricity will reduces the usage of the earth’s resources such as gas and oil.
According to the Union of Concerned Scientists, “Renewable energy — wind, solar, geothermal, hydroelectric, and biomass — provides substantial benefits for our climate, our health, and our economy.” One major benefit is that there would be little to no global warming emissions. Currently, electricity production accounts for about one-third of the emissions put off by the United States, mostly due to coal-fired plants. Renewable energy sources would produce little to no emissions. “According to data aggregated by the International Panel on Climate Change, life-cycle global warming emissions associated with renewable energy—including manufacturing, installation, operation and maintenance, and dismantling and decommissioning—are minimal” When comparing renewable sources to natural gas, which emits between 0.6 and 2 pounds of carbon dioxide equivalent per kilowatt-hour (CO2E/kWh), renewable sources such as wind, solar and hydro-electrical power emit somewhere between .07 and .5 (CO2E/kWh). It is obvious that renewable energy is the way to go in order to solve the energy production problem. (Benefits of Renewable Energy
increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions… a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy
Thomas Alva Edison is a very well-known American inventor. He invented about 1093 devices that influenced us greatly, such as light bulb, microphone, telephone receiver, universal stock ticker, phonograph, kinetoscope (used to view moving pictures), storage battery, electric pen, and mimeograph. Edison also improved many other existing devices as well. In the period from 1878 to 1880, Thomas Edison began serious research into developing a practical incandescent lamp. Edison and his associates worked on at least three thousand different theories to develop an efficient incandescent lamp. In 1878, Edison built his first high resistance incandescent electric light. Incandescent lamps make light by using electricity to heat a thin strip of material (called a filament) until it gets hot enough to glow. Many inventors had tried to perfect incandescent lamps to "sub-divide" electric light or make it smaller and weaker than it was in the existing arc lamps, which were too bright to be used for small spaces such as the rooms of a house.Edison's lamp would consist of a filament ho...
