Conventional Electrical Energy Generation
Over 65% of the world's electrical energy used today is generated by steam turbine generators burning fossil fuels as their source of energy and large scale fossil fuelled plants provide most of the world's base load generating capacity.
The electricity generation process is described in detail in the section about steam turbines. This page considers issues concerning the fuel.
Fuels
Fossil fuelled plants use either coal (60%), oil (10%)or gas (30%) in purpose designed combustion chambers to raise steam. These are all non-renewable resources whose supply will ultimately be exhausted. The energy content of these fuels and their variants is shown on the Energy Resources page
Oil is probably the most convenient fuel and thirty years ago it accounted for 30% of the consumption but it has mostly been replaced by coal as oil prices have risen faster than the price of coal due to insecurities of supply. At the same time, the premium value of oil for transportation and chemical uses, rather than for just burning it to extract its calorific value, has also been recognised.
Coal is the least convenient. Its calorific content, on average, is less than half that of the other two fuels. Handling and transporting it is more difficult and it produces large quantities of residues, ash and greenhouse gases, some of which are toxic, depending on the quality of the coal.
Alternatives to using fossil fuels for raising steam are discussed in the section about steam turbines.
Electricity Generating Plant
Drax Power Station
As a benchmark for comparison, in the UK, one power station, Drax, produces 7% of all the country's electricity. It burns 13 million tons of coal a year in 6 X 660 MW coal fired generators providing a total of 4000 MW capacity.
Plans were in place to use 10% biomass co-firing with coal. This would require 400,000

...dependent humans are on electricity. The production of electricity comes from so many different resources, but primarily from non-renewable resources such as coal, oil, natural gas, and nuclear power plants (Starr, 2004). As electricity is produced this way our planet is depleted further of fossil fuels as well as the planet being pumped full of more Carbon Dioxide (CO²) than the planet can handle. Imagine nothing changing when it comes to energy production and take a look at our planet in 100 years. Do you see a planet that is inhabited, or do you in fact see a planet that is something akin to the movie Wall-e? It is a scary thought, but alternative energy resources are out there, and these alternative energy resources will enable mankind to inhabit Earth for many more years and even centuries to come. Since the year 1900 tests on world temperature have been documented and studied showing that the planet temperature is raising by approximately 1.1 degrees per century (Phillips, 2008). The reason for this rise in temperature is clearly due in part to the rising of carbon dioxide in the atmosphere. The process of producing electricity is a major contributing factor to carbon dioxide as fossil fuels are burned to produce the electricity. Currently, fossil fuels used for electricity emit approximately 6,000,000,000 tons of carbon dioxide into the atmosphere per year. With this said, not only is electricity being limited by the limited sources of fossil fuels, but our planet is also...

...to be realized through careful design and consultation. Additionally, it also provides a profile of a major wind power company in Canada. Problem Electricity generation produces more pollution than virtually any other single industry in Canada. Pollution, air quality, acid rain, nuclear waste and global warming are the unwanted side effects of traditional power production that endanger the environment. Every day, many fossil fuel consuming contraptions spew out gases that pollute the environment. However, when the fuel supplies for these devices run out, they will grind to a halt. To prevent this, Canada needs to find an alternative to unstable and polluting energy sources. Purpose The purpose of this report is to examine wind energy as alternative energy source and effectiveness at reducing emissions by replacing power generated from fossil fuels. Scope The report will examine wind power as an alternative energy source and nonmarket issues. Wind power usage in Canada has been growing at a significant rate in the past few years and has generated considerable interest in industry, government and the public. Introduction As a renewable energy source, wind power is gaining popularity as an alternative to fossil fuel, nuclear and hydro power generation. In Canada, provinces are required to achieve 15% of their energy consumption from wind by 2012 as provinces...

Natural Gas

...Natural gas is a fossil fuel. Like oil and coal, this means that it is, essentially, the remains of plants and animals and microorganisms that lived millions and millions of years ago. In the 19th and early 20th centuries, natural gas was used primarily for street and building lighting, providing what was known as gaslight. Today, improved distribution of gas has made possible a wide variety of uses in homes, businesses, factories, and power plants. The U.S. Energy Information Administration projects a 50 percent rise in global natural gas consumption between 2010 and 2035, with growth in Brazil and China driving increased demand. One of the main reasons for this increase is due to electric power. Natural gas power plants usually generate electricity in gas turbines, directly using the hot exhaust gases of fuel combustion. There are numerous reasons why natural gas is becoming more reliant for generating electricity than other fossil fuels. While coal is the cheapest fossil fuel for generating electricity, it is also produces more pollution. The electric generation industry, in fact, has traditionally been one of the most polluting industries in the United States. Regulations surrounding the emissions of power plants have forced these electric generators to come up with new methods of generating power, while lessening environmental damage. New technology has allowed natural gas to play an increasingly important role in the clean generation of electricity. There are several...

...Introduction: The planet that is home to all known life in the universe has been facing hardships since its formation almost five billion years ago. However, the rapid evolution and advancement of the human race has put the Earth through its greatest challenge yet. The last few centuries saw the Earth undergo massive irreversible damage at the hands of the human race. Although previous attempts were made at dealing with the problem of environmental damage and the non-sustainable use of resources, none were as clear-cut and globally united as the Millennium Development Goals. The Millennium Development Goals, hereafter referred to as the MDG, was signed by all 193 members of the United Nations. The MDG focuses on a wide range of human problems; from poverty and health to environmental damage and the non-sustainability of the current resource usage (Nations, 2010). This was so important because it was the first time that so many nations united together to attempt to solve the world’s biggest problems. Although a lot of the set targets were very ambitious, they were certainly within the realm of reality with proper funding and planning. The following report proposes a plan to carry out a sub-section of one of the goals in one region of the world. Although it would be a very small scale when considering all the goals of the MDG and all the regions of the world, it would provide a morale booster that shows that these goals can actually be achieved with sufficient funding and planning.

Brazil has the third-largest electricity sector in the Americas, behind the United States and Canada. Brazil is currently experiencing its worst drought in 40 years, which has contributed to electricity blackouts in many Brazilian regions. Brazil has spent more than $5 billion to subsidize electric utilities replacing lost hydroelectric generation with fossil fuel-fired generation, including large amounts of liquefied natural gas. (which is shown in the graph in the recent increase in fossil fuels) Brazil was the largest producer of petroleum and other liquids in South America in 2013. Brazil is the second-largest producer of hydroelectric power in the world, trailing only China, and the country depends on hydroelectricity for more than 75% of its electric power supply.

Are You Ready to Live Without Nonrenewable Energy Sources

...Energy Sources What will you do when your lights go out because there are no more fossil fuels to fuel the electricity needs of our nation? As many of us have dealt with power outages for one reason or another, they were usually for a very short period of time that may have seemed like forever. For the past few decades there has been a huge push for conserving and preserving energy. Many live lives from day-to-day without ever giving any thought as to where their electricity comes from. Believe it or not, the depletion of non-renewable energy sources poses growing concerns for future generations if energy conservation and preservation are not taken seriously. “Coal, oil and natural gas are called fossil fuels because of the way that they were formed, the end products of photosynthesis that formed millions of years ago in large deposits of carbon compounds” (Berg & Hager, 2007 p. 7 & 105). Fossil fuels are also referred to as nonrenewable energy sources because natural processes do not replenish these sources within a reasonable period of time in which to be reused, they take millions of years to form. Coal and natural gas are most widely used to provide our homes with heat and electricity, and to fuel industrial and manufacturing plants. Nearly every mode of transportation uses some form of crude oil or petroleum for fuel. Coal is the most abundant fossil fuel in the United States and is also the home of the largest known coal reserves in the world...

...hotmail2008 Table of Contents Executive Summary 2 Introduction 3 Wind Energy Data 5 Analysis 6 Conclusion 8 Bibliography 9 Executive Summary The majority of our nation’s energy is highly dependent on finite fossil energy sources, like coal and oil. Using fossil fuels to create electricity creates emissions that are both harmful to the environment and our health. Renewable energy sources provide a clean and viable long term alternative to fossil fuels. Renewable energy is energy generated by natural resources in the form of solar, wind, geothermal, hydroelectric, and tidal waves. Among the diversity of renewable energy, wind energy is the fastest growing power technology in the world. According to the U.S. government Energy Information Administration, the production of wind energy will be at least 20% by the year 2030. This report will prove the validity of this statement by using hypothesis analysis. Hypothesis analysis will reject the null hypothesis that wind energy production will be less then 20% in favor of the alternate hypothesis that states wind energy production will be at least 20% or greater. Introduction The majority of our nation’s energy is produced from the burning of fossil fuels, like coal, oil, and natural gas. Life as we know it and our economy revolves around these finite resources. Unfortunately, with our great demand for energy, especially gasoline, world production of oil has already reached its maximum capacity and seems to...

...#1 Energy can be converted from one form to another by one form of energy decreases, other forms increasing, because the total energy has to stay constant and that’s only if you're looking at an isolated object. Potential energy can be converted to Kinetic and kinetic can be converted to potential. (Tillery, Enger, & Ross, 2009, p. 67). Energy can be converted in three basic ways through 3 actions of forces. Gravitational Forces is when gravity accelerates a falling object, its converts its potential energy to kinetic energy. Electric and Magnetic Force Fields can convert charged particles, which electrical fields use forces, possess potential energy of an electric field in a way similar to that of an object in a gravitational field. Frictional Forces can be converted into thermal energy, which is heat, whenever the object slides against another object. An example of an energy being converted from one form to another is a lightbulb. It converts electrical energy to radiant energy. A car can covert chemical energy to mechanical energy. A solar cell converts radiant energy to electrical energy to mechanical energy. A fuel converts to chemical energy to heat energy. What we mean by fossil fuels is that Fossil fuels are energy resources that come from the remains of plants and animals. These remains are millions of years old.
