various renewable energy sources‚ fuel cell technology has received great attention as an alternative to the conventional way of getting energy due to its high efficiency‚ clean operation and cost efficient supply of power demanded by the consumers. Proton exchange membrane (PEM) fuel cells technology plays a leading role for many applications when comparing with other competitive types of fuel cells. The world is in high demand for clean alternative fuel source and PEM fuel cells could be that change with

fossil fuels that is destined to burst. The creation of fossil fuels has taken place over many millions of years and is said to still be affecting the world around us. As we know‚ the sun is the source of most of the energy on our planet. Photosynthesis occurs all around us and is essentially the building block of life. The weight of the earth above the decaying material has provided the environment with the means to convert that material into fossil fuels. The burning of fossil fuels is more

Amanda Poland Prof. Kurzinski English 101 April 10‚ 2012 Alternative Energy Sources In the world today‚ alternative energy sources are becoming more and more of a necessity. Right now‚ the world’s energy demand is greatly increasing mostly because of population growth. Even though the rate of population growth is very diverse in different countries‚ the world’s population doubles about every thirty years. The world energy use is doubling every fourteen years (Hodgson). Still‚ the main energy

is less obvious‚ kinetic energy can be easier to identify. Energy comes from different sources‚ some that are renewable and others that have a limited supply. The world that we live in has a high demand for energy‚ and it is important to find alternative sources that are renewable and cost effective. It is beneficial to reflect on the energy that is used daily‚ try to find ways of using renewable resources‚ and making it a personal duty to conserve energy by reducing daily usage. From the moment

English 111 Argumentative Essay Have you ever thought about the things we teach at our public schools? How everything that is said to a student has an effect on the way they think or understand things. How are we sure that we teach them everything they need to know? And who decides the purpose or requirement of each class given? Education is to enlighten the young and naive to better their purpose in our society; and by teaching them both Evolution and Intelligent Design it give them more knowledge

Decreasing Fossil Fuels Over the past century America has continuously used its own fossil fuel resources and paid handsomely for additional supplies‚ in the race to stay current with modern technology and life .The possession of this resource has made the United States a very prosperous and powerful nation. The same fossil fuels that’s has made America such a powerhouse are the same that are damaging the environment and economy they have enabled. It is imperative that we decrease our dependency

Proponents and opponents of biotechnology being a distraction is argued by Frances Moore Lappe. Multiple argumentative points are presented by Lappe on what’s the right issue to focus on. The first point Lappe argues is the amount of food we have. Lappe goes on to say‚ “They were telling us that we had reached the Earth’s limits to feed ourselves‚ but in fact there was more than enough food for us all” (249). In other words‚ “they” were telling us that there is less food to eat than Lappe believes

This increased content of carbon dioxide increases the warmth of our planet and is the main cause of the so called “Global Warming Effect.” One answer to global warming is to replace current technologies with alternatives that have comparable or better performance‚ but do not emit

Biofuels Coal and crude oil are non-renewable resources. They take so long to form that they cannot be replaced once they have all been used up. This means that these fossil fuels are likely to become more expensive as they begin to run out. Petrol‚ diesel and other fuels produced from crude oil make a range of harmful substances when they are burned‚ including: carbon dioxide carbon monoxide water vapour particulates (solid particles) sulfur dioxide oxides of nitrogen or NOx.

In recent decades‚ we have seen a remarkable advancement in science and technology. Owing to this‚ many wonder why the primary sources of consumer energy remain non-renewable fuels; petroleum (36%)‚ coal (27%) and gas (23%) [International Energy Agency‚ 2013]. The issue with this is‚ “fossil fuels” which took millions of years to form are running out at an unprecedented rate‚ and there is no consensual view as to what will replace them. There are many reasons why the general population should be
