Green Technology Definition and Examples

Green Technology Definition and Examples Green technology, also known as sustainable technology, takes into account the long- and short-term impact something has on the environment. Green products are by definition, environmentally friendly. Energy efficiency, recycling, health and safety concerns, renewable resources, and more all go into the making of a green product or technology. Go Green or Face Extinction? Since the invention of the steam engine kicked off the Industrial Revolution, our planet has suffered rapid changes in climate that include increasingly severe droughts, increased depletion of groundwater reserves, seawater acidification, rising seawater levels, the rapid spread of diseases and macroparasites, and the extinction of species.  Unless we intervene, these changes may prove irreversible. Green technology offers us the best hope to counteract the effects of climate change and pollution. Why? The world has a fixed amount of natural resources, some of which have already been depleted or ruined. For example, household batteries and electronics often contain dangerous chemicals that pollute soil and groundwater with chemicals that cannot be removed from our drinking water supply and wind up in food crops and livestock grown on contaminated soil. The health risks alone are staggering. Plastic pollutants are another nonsustainable resource thats destroying the ocean habitats of sea creatures around the world- killing off fish, birds, and countless other species. Larger pieces pose choking and strangulation hazards, while the tiny particles of disintegrating plastic are making their way into the bottom of the food chain. As larger fish feed on contaminated krill, they too become contaminated and if those fish are subsequently harvested for human consumption, the contaminants are going to wind up on your plate and in your stomach. Not so appetizing, right? Fast Facts: Principles of Sustainability There are three principles which define sustainability in any type of material, as described by the American ecologist and economist Herman Daly:  Nonrenewable resources should not be depleted at rates higher than the development rate of renewable substitutes.Renewable resources should not be exploited at a rate higher than their regeneration levels.The absorption and regeneration capacity of the natural environment should not be exceeded. Renewable Energy vs. Nonrenewable Energy Nonrenewable energy resources include nuclear, hydrogen, coal, natural gas, and oil. All of these currently fail the definition of sustainability in one way or another but most painfully in the ability of the environment to absorb and regenerate the expenses related to their extraction or production.   One of the best-known examples of green technology is the solar cell, which directly converts energy from natural light into electrical energy via the process of photovoltaics. Generating electricity from solar energy equates to less consumption of fossil fuels, as well as the reduction of pollution and greenhouse gas emissions. While some detractors argue that solar panels are expensive and unattractive, new inventions may be just around the corner to offset these concerns. Community solar groups, in which renters will share solar panel products, and new spray-on photovoltaic film using perovskites that have the potential to convert regular window glass to solar collectors are just two possibilities on the horizon that show great promise for the future of solar assets.   Other renewable energy sources include hydro, biomass, wind, and geothermal, but unfortunately, these assets are not currently be exploited at adequate levels to replace nonrenewable sources. Some members of the energy industry are dead set against going green, while others see it as both a challenge and an opportunity.  The bottom line is that while non-renewable energy resources currently comprise 80 percent of the worlds energy requirements, over time, thats simply not going to sustainable.  If we hope to maintain life on our planet, emerging green energy technology must be used alongside existing methods to transition from the unsustainable to the sustainable. The Power of Positive Green Thinking Here a just a few reasons why going green is in everyones best interest: Inventors should know that green inventions and clean technologies are good business. These are fast-growing markets with growing profits.Consumers should know that buying green inventions can reduce energy bills and are often safer and healthier than non-green counterparts.  Even making small changes can have a large-term impact. For instance, consider the waste created by plastic water bottles. Of course, drinking lots of water is a healthy practice but changing out reusable water bottles for disposable ones is health-promoting, eco-friendly, and green.

Research method - Essay Example The idea of having collaborations done online is to allow learners to share knowledge, interact with their colleagues, and exchange thoughts through online portals (Geiss & Roman, 2013). Online learning incorporates collaborative learning, which is recognized as a greatly valued opportunity (Tsai, 2011). It not only of involves access to fellow students, but also there is the chance of working together, which makes the online learning more effective, when compared to the traditional face-to-face classroom setting Generally, collaboration has become one of the essential skills necessary for effective functioning within the online community. It is necessary that we know how students learn and communicate and that we understand how the increasing functionality of technology is raising the bar of communication and collaboration (Sulisworo, 2012). Collaborative learning by definition refers to environments and methodologies in which learners engage in a common and authentic task wherein each peer depends on and is accountable to the others (Tsai, 2011). Bouroumi and Fajr (2014) have defined collaboration and cooperation in the light of the strategies used by teachers in making it possible for interactions among the students while working together in order to be more efficient. Cullen, Kullman & Wild (2013) explained that the practice of collaboration involves the attempt to have learning together or otherwise where two or more individuals gather for learning purposes. Some theoretical perspective s including cognition, social cohesion, and motivation should support the process. Collaborative learning has been defined as a pedagogy in which learners come together in groups and learn from each other through cooperation. Each student takes responsibility for the learning of other students in the group as well as his or her own learning, and each helps

Art Blog - Assignment Example Galleries open here and there, and museums feature exhibits that are not to be missed. Yet that visit to a community garden opened me to a whole new world of the art scene. Of course the Museum of Contemporary Art, the L.A. County Art Museum, and the Getty Center house several of the best pieces of art in the world. But ever since a community garden opened my eye to something new about art, I have been keener to observe those Chinatown galleries that feature up-and-coming artists that houses a more â€Å"homely† type of art. I have been more appreciative of the unpretentious airs in several of these galleries like Kathryn Brennans, Tom Solomans, and China Art Objects. What that little community garden did to my art perspective was huge. Since then, I never have to look far to see art in my surroundings. I can see it in simple places and things. In the community garden, I never thought the day would come where I would be looking at garden plots as works of art. Yes, they may no t be technically pieces of art, but works of art they are. There is no such thing as being too radical or being too conventional in art. Now I know there are no rules. Art is when it moves you even when you do not know why. Aside from being appreciative of art, I also love books. What moved me the most in the Getty Center is its collection of books within the Getty Research Institute and the vast collection of pictures of different architectures. Additionally, I also find it fascinating to stare at the illuminated manuscripts and glimmering decorative arts and furniture. I agree with Natalie that the museums programs and activities for kids and families are a joy to behold. I visited the place a few times, and I must state that for adults who do not have any kids in tow, it is worthwhile to catch the nighttime view of the place. I am all for self-expression. Sadly, the street art scene in Los Angeles is something

Graduation Speech -- Graduation Speech, Commencement Address

Today is both an end, and a beginning. After thirteen long years we have finally concluded our Kutztown education. It’s been a bumpy road, filled with defeats, victories, and surprises. We’ve learned a lot along the way, and not just science and math and English, although our teachers have made sure we picked up plenty of that too. Seeing the same people day after day has taught us what friendship is—and isn’t, and we’ve learned that life is not always fair. We’ve also developed some interesting skills, like how to dodge buckets—or freshman—in a crowded hallway on a rainy day. Or how to fight off heat stoke in the sweltering science wing and hypothermia in the over air-conditioned English classrooms. Even so, we still managed to scream the loudest of any class at every pep rally since our freshman year. We’ve survived social dramas and standardized tests and finals. And now, after all the homework and the late nights stud ying and the 14,580 hours of sitting in class, yes I did the math, we’re here to celebrate the fact that we’ve made it. When we started kindergarten this moment seemed so terribly far away. We were only five years old ourselves, and thirteen years might as well have been an eternity. By the time we reached junior high we were too busy worrying about whether or not we would be able to open our lockers or remember where our classes were to give the passage of time much thought. By 9th grade there was the stigma of being freshmen, and then in the blink of an eye three years had passed and our senior year had snuck up on us. Suddenly everything we did was a milestone; our last concert, our last assembly, our last test, even our last day of classes. By this point senoritis had set in, and we were ready to leave and... ... not to listen. Without your dedication we would not be where we are today, and I don’t think I’m alone in saying that I count many of you as friends, and not just teachers. To the band and the stage crew, thanks for helping out on our special night. And to the class of 2004: sail. Sail from this place into the vast and unchartered future, but don’t forget to look back every once and a while and remember where you came from. High school is over, but you can take the memories made here with you wherever you go. Pack them away in your heart, and when you’re feeling afraid or discouraged remember the thrill of winning that football game, or the warmth of your best friend’s smile, or the security of simpler times. But do not dwell in the past forever, for it is time to move on. Follow your heart, reach for your dreams. The world awaits us, and it’s time to make it ours.

General Economic Indices for the Power Tool Market Essay

In assessing the power tool industries, it can be found that there are several general economic indices which have are important in assessing the viability of the industry. There are four of these which could be assessed for the purpose of the Able Corporation as they pursue their goals with their products. These four general economic indices include housing starts, expenditures for residential construction, expenditures for commercial construction, and expenditures for home repairs and improvement. First, the housing start statistics which have become relevant to the industry â€Å"represent the beginning of the construction of new privately owned single-family homes, townhouses, and multifamily apartment buildings† (Frumkin, 2005, p. 132). Moreover, it excludes infrastructures for housing which fall under mobile homes, group quarters, public housing properties, renovations made to existing houses, and converted housing from non-residential to residential housing (Frumkin, 2005). From the historical data presented from the US Census Bureau, there is an erratic trend that can be seen from the year 2004 to 2008. However, it is apparent that there is a continuous decrease from the year 2005 up to the 2008 leaving the year 2004 as the only exception. The respective values for each year are 1,955,800 for the year 2004; 2,068,300 for the year 2005; 1,800,900 for the year 2006; 1,355,000 for the year 2007; and 905,500 for the year 2008 (â€Å"New Privately Owned,† n. d. ). From the trend shown, it is made apparent that the housing units which have been started are becoming lower every year from the US data. Second, there are also relevant data which are made available for the expenditures which are placed for residential repairs and improvement. This type of data shows the amount of money that has been used for the purpose of improving the residential places for purposes of repairs and improvement. For the year 2003, the data shows that $179,700,000,000 has been spent on the first quarter, $173,200,000,000 has been spent on the second quarter, $187,400,000 has been spent on the third quarter, and $166,700,000,000 has been spent on the fourth quarter (US Census Bureau News, 2008). On the other hand, there are costs of $198,900,000,000 for the first quarter, $192,600,000,000 for the second quarter, $202,100,000,000 for the third quarter, and $200,500,000,000 for the fourth quarter (US Census Bureau News, 2008). For the year 2005, the respective value for the first to fourth quarters are $213,600,000,000 $192,800,000,000, $220,900,000,000 and $235,500,000,000 (US Census Bureau News, 2008). For the year 2006, the values for the respective four quarters are $232,200,000,000, $225,000,000,000, $231,000,000,000, and $226,000,000,000 (US Census Bureau News, 2008). As for the year 2007, the value for the first to the fourth quarter is $230,900,000,000, $227,700,000,000, $213,200,000,000, and $236,600,000,000 (US Census Bureau News, 2008). From these values, it is shown that the expenditures for each quarter and across the years are increasing such that there has been more cost spent for this on the latest years of the historical data. Third, the report of the US Census Bureau also shows that there are also expenditures for residential construction which can be studied from the year 2003 to 2007. For the year 2003, the total expenditure is $705,276,000,000. The succeeding values are: $803,305,000,000 for 2004, $897,989,000,000 for 2005, $937,047,000,000 for the year 2006, and $875,010,000,000 for the year 2007 (â€Å"Construction and housing,† 2009). While the trend shows that here is a constant increase from the year 2003 to the year 2006, there is a sudden plunge for 2007 which can be accounted to several economic factors that prohibit the construction of new residential infrastructures. Fourth, there is also an economic index available for expenditures on nonresidential units, which is also taken from the US Census Bureau. From the year 2003 to 2007, the respective values are $229,335,000,000, $238,478,000,000, $256,644,000,000, $295,715,000,000, and $349,566,000,000 (â€Å"Construction and housing,† 2009). From these data, it can be observed that there is a continuous increase in the amount spent for the purpose of construction nonresidential units. In relation to the power tool market, these economic general indices are considered to be important because of the role it plays in terms of the demand for power tools which are required for construction. The housing start data would dictate how many new power tools may be required together with the amount of expenditures that are seen to be used for improvements and construction of new infrastructures. The fact that power tools are considered to be a necessity for the construction and repair of housing and nonresidential units relates this industry to the construction of housing and nonresidential ones. During cases where there are disparities, it is important to note that these general economic indices will be of great help only when accuracy is present. However, when there are cases where it is difficult to see which of the current findings are accurate, there should be information from other related economic factors that come from the government which could be a reliable source of data. Thus, it can be seen that there are several factors which affect the power tool market considering the economic relations it has with the construction industry. There are several ways through which the economic forecasts for the power tool industry can be obtained in relation to the construction data. References Frumkin, N. (2005).

The culture and tradition are considered as a national treasure of the country, therefore the people living in Nepal are always willing to protect and preserve their culture and tradition. Being a patriarchal country, some of the extremely stereotypical cultural and traditional beliefs, which are directly dominating to women, get exaggerated. Even though the stereotypical beliefs are disempowering to women, the people living in Nepal are still following the same stereotypical beliefs, and Nepali women are unable to uplift their personal freedom from being curtailed.
