1. Hydrogen Economy
1.1 Introduction
Coal, oil and natural gas have been at the forefront of powering the world since the industrial revolution. Whether this power is used for new technology, transport links or energy the threat that fossil fuels has on the environment is colossal. Energy availability for the masses is the main dominant challenge in the 21st century and is driven by the world’s forever increasing population and the industrialization of developing countries (Crabtree, Dresselhaus, Buchanan, n.d.). Global supplies of fossil fuels are only available in certain areas of the world and are becoming increasingly difficult to extract. This is where hydrogen comes into the picture and the proposal of a hydrogen economy.
The main components of the hydrogen economy are to use it as a fuel for transport, stationary power and as an energy store. There are a few methods for the generation of hydrogen; this could be from steam reformation, carbon gasification, biofuels or water electrolysis. This replacement for fossil fuels needs a lot more research to be completed before it can match the supply of energy that is needed to power the world. The development of hydrogen to be a major power source needs to be invested in soon due to the unpredictability of when the fossil fuels will run out and the economic grip that some countries have on them.
1.2 Sustainable Energy for the future
Nowadays fossil fuels are classed as unsustainable due to the possibility of them running out in the near future and that the waste produced by them, greenhouse gases, cannot be absorbed by nature. The way forward for future generations is sustainable energy which has had recent advancements like: solar power, hydroelectric, geothermal. These are all ...

Our energy needs have significantly changed since the first Industrial Revolution that took place in the period from about 1760 to sometime between 1820 and 1840. Before this time period, our energy needs were modest. For heat, people relied on the energy of the sun, but when it failed them, they burned wood, straw and dried dung. For transportation horses and the power of the wind was used in sails. For agricultural work animals were used to do the jobs that could not be done with man labor. By harnessing the power of steam and wind simple machines could be run to grind our grain and pump our water. The Second Industrial Revolution, also called the Technological Revolution is considered to have begun around the time of the introduction of the Bessemer steel in the 1860s. This technological Revolution is considered as the second phase of the Industrial Revolution that resulted in factory electrification, mass production, the creation of production lines and the development of machine tools. With the appearance of the low cost automobile and the wide spread of electricity our society's energy needs have changed forever. Since the modest beginning of the oil industry in the mid 19th century, petroleum has risen to global dominance leading to mass consumption as the primary fuel to generate electricity, heat, to power our homes, cars and to support economic growth. Unfortunately, as a consequence of industrialization, atmospheric CO2 levels started to rise in proportion to the usage of fossil fuels. This trend raises some concerns about the well being of our environment, and researchers around the world started to look for alternative, cle...
Consequently, lower, regulated tuition will make college more accessible for those who are worse off. College should not just be limited to the wealthy. Senator Bernie Sanders once said, "Education should be a right, not a privilege. We need a revolution in the way that the United States funds higher education." (Sanders, Bernie. U.S. Capital rally. March 27, 2015) It should not matter where one lives or where they are on the social ladder. What should matter is if a student wants to open his or her mind, learn from a college
Sometimes I think about how America’s founding father’s intended to guarantee everyone a free education; not a professional education, but the basics anyone needs in to be accepted in society. Unfortunately, I think the standards have changed. College is now just as necessary as high school. Does that mean it should be free? This has been a quiet issue going around in America among our youth because they the financing of college. Lowered, yes. Free, no. College is a privilege, not a luxury. It is only mandatory to get a high school education for most basic jobs that should be able to let you survive on your own. Today in our world, parents put a huge emphasis on college and its benefits but no one is willing to lower the price or allow a full ride as in high school. Society wants us to go to school but they continue to raise the price which doesn’t make any sense.
In nature hydrogen is always found combined with other elements, which means it has to be manually made by passing an electric current through water to form hydrogen and oxygen. There is a tremendous amount of energy involved in splitting the molecules to free the hydrogen from its captor. The current method of producing hydrogen from water is through the use of oil and coal. Oil and coal are the two main resources the world is trying to cut back on. The main purpose of using hydrogen is lost when considering the actual manufacturing process of hydrogen contributes a significant amount of carbon dioxide. When the big coal and oil companies start investing their profits in hydrogen, something has gone awry. Each company sees its future limited and wants to ensure their survival. Since they have the most money they will be the main producer of hydrogen. The hydrogen economy will benefit the mining and oil industry at the cost of the clean-energy dream.
There are so many students who would extremely grateful to attend any four year institution but can’t because of the lack of funds. College life can be very stressful, and the process can is very frustrating to most students the first two years. When the cost of college tuition is compared to the 21 century financial economy the cost does not make sense, because for a middle-class family it is impossible to afford sending their child to any four-year institution. It hard for students to graduate with the stress to pay-off hundreds and thousands of dollars in loans. Going to college is stressful enough without the need to worry about how we’re going to pay for it and what other costs will continue to rise with getting a degree afterwards. With the current increase of unemployment rate and the thought of going to college seems like a farfetched goal. Many people choice not to attend a four year institution, because they did receive a scholarship or enough government funding. Having a college background is very important for professional growth, it will eventually limit career opportunities. My stand point is, you may not leave college doing the same thing you began with but the life experience is endless. College experience not only gives knowledge that builds you into a better person by giving a broader erosion. With the cost of tuition increasing will hurt our generation, by causing physical and mental stress but in the end it will all pay off. Not all colleges are for the blame; some of the blame is our economy and other factors play a big roll. As students we need to be aware of all our resources offered, such as Pell Grants, and government scholarships. For example, the some states will pay for a student’s college if they graduate high school with a GPA of 3.5 or higher. There are many states that are willing to pay for all or some of college tuition only if students are willing to use
As the old adage that I was constantly told by my parents as a mischievous teen goes “There is a time and place for everything and it is called college”. The problem surrounding today’s youth is the fact that the “everything” referred to by the former is now too often not only encompassing the mischief performed by young adults but also the unrelenting stress of affording a higher education and the mountain of debt that is smothering young Americans seeking a better future. Despite arguments that providing free college provides more benefit to rich students than poor ones and that free education would make a degree worthless, free college educations is the best tool to close the income gap plaguing this country and revive the American Dream.
George Washington Carver once stated that: “Education is the key to unlock the golden door of freedom.” An education is the first step to a job, a salary, recognition, and a successful life. The greatest pride of a nation is not their military, nor their economy. It is the ability to say that their people are educated. Now, a higher education is so closely connected to the American Dream that it is nearly impossible to reach one without reaching the other. However, now access to that dream is fading to many. Over the last 35 years, a trend in rising tuition prices has brought college education out of the reach of many low and middle class families. Between the higher tuition costs and lower average salaries, families are often forced to choose between losing access to a higher education or being burdened with debt for the rest of their lives. In order to restore access to the basics right of American citizens, it is necessary to make education more accessible by making it
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
Even though, colleges and universities might have an increasingly negative reputation due to things like high tuition fees, less faculty, and less than desirable graduation rates, it is still very important to attend college. Having an education does not necessarily mean going to school for years in order to have a great job with a great pay. Of course going to college, and getting a degree can lead students to a well-paying job instead of having to settle for making minimum wage with only part time opportunities. College is about more than just getting a degree. It is something that plays a crucial part in future success. Statistics may say that the majority of students end up in debt trying to pay for college, or
College is the key to a well suitable and successful life it opens the door for us to a wide opportunity of careers. It also helps people revolutionize the world with all the educated people inventing and discovering new advanced things. I believe that us Americans, if we want to go to public college it should be totally free for the ones who aren’t financially set to pay it off without going into debt and taking out school loans. The problem is that many of Americans are choosing not to go but instead go straight into the workforce due to the fact that college tuition is very expensive to afford for low-income families and even middle-class ones too. Knowing they have the skills to
It is now well understood that use of fossil fuels as energy sources is unsustainable and damaging to the environment. The world is now moving in the direction of using renewable energy sources that are better for the environment and mitigate some of the damage that has been done. While this is virtuous it is not without its challenges. One of the biggest problems is that renewable energy sources have fluctuating outputs. It is therefore of the utmost importance that energy storage methodology is introduced. To this end, we are introduced to the hydrogen economy. This is used to describe the quintessential role hydrogen has yet to play in the worlds energy supply. Hydrogen is a clean and flexible energy
Hydrogen is one of the most abundant elements on the earth. It can be found in the oceans as well as the atmosphere. Over the last few years, talk about the future of hydrogen power has grown from a whisper to a roar. The use of hydrogen is not just the burning of the gas, but of its use in a fuel cell. Fuel cells might be the device that causes the extinction of the internal combustion engine. A fuel cell is a device that produces electricity from a fuel and an oxidizer, a substance that combines with the fuel. The fuel and oxidizer react chemically at two separate electrodes to produce the direct electric current; These cells use hydrogen as the fuel and oxygen as the oxidizer. Hydrogen power could be the silver bullet to the current and future energy situation.
The world's fossil fuels are running out. With the average amount of time it takes for coal to form being 300 billion years, the earth can only renew them so fast. Fossil fuels, like coal and oil take the earth billions of years to reproduce so an effective alternate energy source must be explored. Fossil fuels or crude oil has been around for a long time and can be refined to form a number of products such as gas, gasoline, kerosene, gas oil or diesel. We are also running out of oil which is also a non-renewable resource. According to ecotricity.co.uk, if we continue to consume fossil fuels like this, they will run out by approximately 2088. The use of fossil fuels is also dangerous to the environment. Burning coal and oil produces smog and greenhouse gasses but despite the environmental risks and the fact that they are going to run out, we humans continue to use them. Why? You might ask. The simple answer is because they are cheap easy to get and effective. The harsh reality is that no alternative fuel can match the efficiency of coal and oil. In this paper we will compare the efficiency of renewable resources to the efficiency of oil and coal.
In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
