Fuel Cell Essay

and do not cause so many pollutants, however they only contribute a smaller amount to the energy pyramid. These sources include hydro-electric power, wind power, solar energy and biomass energy. Most of these fuel sources do not produce as much energy as efficiently as the majority of fuel sources used today. Solar power is a clean source of practically inexhaustible energy. Solar plants are easy to construct and solar power is safe. It has many uses from heating to direct electric energy generation

Another consequence of using Acid rain is rain that contains high levels of nitric and sulphuric acids, which are the result of burning fossil fuels because when sulphur dioxide and nitrogen oxides are released into the air as byproducts of burning fossil fuels, the SO2 and NO react with water, oxygen and other chemicals to form sulphuric and nitric acids. These then mix with water and other materials before falling to the ground. This rain can be harmful to plant and animal life. For example The

specifically how fossil fuels add to the effects of global warming? Fossil fuels are organic hydrocarbons formed from the remains of dead animals and plants which have decayed for millions of years, there are three main types coal, oil and natural gas. While oil is the most biggest form of energy source today, coal was discovered first and has been use since 1,000 BC and it was in the 1800s that it replaced biomass as the primary source of energy while massive consumption of fuel didn't start until early

types of alternate fuels for cars at our disposal, such as Ethanol, Natural Gas, Electricity, and Hydrogen Fuels. We can use these fuels instead of normal gasoline fuels that pollute our air and contribute to destroying our environment. Many of these alternative fuels may be less convenient to use, because they are less accessible. However, if people decide to use these fuels then they can make our world a green friendly world. There this a ton of upside to using alternative fuels, according to Larry

Problem with our current energy source • Today, though renewable energy sources exist, fossil fuels are still very prominent in supplying us with the everyday energy that we need. • One of the biggest problems our world suffers today is the mistreatment of our environment, as seen by global warming and pollution which we face today. • Though there are many factors influencing pollution, the following reasons are the most energy focused and are considered by many as the largest causes of our environmental

of the Sport Utility Vehicle (SUV), the average fuel efficiency of cars in the United States has begun to fall from a peak over a decade ago. With technological and material advances made in the last decade, it seems counterintuitive that average fuel economy had begun to decline. In order to understand the advances made in internal combustion engine technology, one must have a basic understanding of

Renewable energy sources are clean energy sources; they can be harnessed from naturally replenished resources. Renewable energy sources are important because they produce little to no pollution. Some examples of renewable energy sources are solar, wind, water, geothermal, bioenergy, and nuclear (Department of Energy 2017). Solar energy is one of the common renewable energy sources. Solar panels are used to convert the heat energy from sunlight to electrical current. When the sunlight is absorbed

so we can finally drive practical low emission cars. It is imperative that we begin driving higher efficiency automobiles because the limited supply of fossil fuels is running low, global warming is becoming a major issue

is where the energy in fossil fuels is originally derived. On earth hydrogen is mostly found in water. Hydrogen makes up roughly 11% of the mass of water and water is roughly 0.09% of the total mass of the earth. [2] How do you free the hydrogen? There are at least four ways do so. The most common is “steam reforming”, 95% of current hydrogen production comes from steam reforming fossil fuels. Environmentalists argue that using carbon-rich fuel sources like fossil fuels would defeat the purpose of

Current State of fuel & World Energy Demand Post 18th Century Industrial revolution has created a dependency on fossil fuels such as coal, oil and natural gas for all technological and transportation demands that engineer modern society. However. Such demands, and even their expected future demands threatens the overall worlds energy supply and generates large strains on the environment. The Hydrogen economy article published by Physics Today in December 2004 anticipated that the world energy demand
