Coal as Source of Energy

Coal is an eminent source of energy, not only in the United States, but also worldwide. Coal as important source of energy will remain so for many years, particularly in many developing countries that are still depend on it. A third of the world’s coal reserves can be found within the United States. The energy content of the nation’s coal resources surpasses that of the entire world’s known recoverable oil. Fossil fuels like gas and oil currently remain the main energy source for the United States’ economy, but we can not dismiss coal’s importance for decades. Coal have advantages over it price stability and will remain an important source of electricity generation. The use of coal is the main source of hydrogen from hydrogen-energy economy and it is an important source of liquid fuel of energy.

The perspective of coal usage and coal utilization for energy industry will not be the same. The disadvantages are several concerns about the environmental impact of coal usage. But there are some efforts to replace current coal utilization by better methods for controlling emissions from burning coal. More investigations should also play an important role in creating a more efficient use of coal, particularly in non-traditional methods to meet the immediate combustion flaws.

The importance of coal for the U.S. economy, locally and around the world, is obvious. For example, a miner of coal gasification in North Dakota, we see the importance of energy, mining, power generation, production of methane. There were five pounds, seven power plants and coal gasification in a radius of 100 miles of Beulah, North Dakota. We have recognized the economic importance of coal for the major regions such as North Dakota, other states in the coal from the United States and the world. Most countries (with the exception of some countries in the Middle East) contain coal deposits. Therefore, this grant of coal deposits in the country the possibility of energy independence, or at least to use options to energy resources than importing energy from abroad.

Obstacles to implementing a more pleasant environment in coal technologies are the financial risks associated are associated with this technology. Reduce the environmental impact of coal production are the source of high energy costs for consumers.

Benefits of Biodiesel

Biodiesel cuts back emissions of greenhouse gases than gasoline, ethanol and conventional diesel. Biodiesel can help you change your energy usage mindset and guided you to renewable energy. I will tell you , last time when I used biodiesel for my car, instead of targeting a fuel pump for the next stop, I immediately went back home where a 55-gallon drum of Missouri grown, 100-percent soy bio diesel, SA and waited in my home garage.

After using fuel from drums in my garage for a few months (sometimes mixed with conventional diesel, because it is necessary to keep biodiesel at lower temperatures), I opened its first biodiesel fueling public station a few miles from home. In addition, the last time public fills the public bio diesel pump, which was the cost of ten cents per liter cheaper than if filled with conventional diesel.

Studies demonstrate that biodiesel exceeds ethanol and surpassing the conventional diesel in reducing climate-altering emissions of carbon dioxide and global energy efficiency. Even though when using a biodiesel blend such as B20 (20 percent biodiesel intermix with conventional biodiesel/80-percent in most petrol stations) it has shown to reduce carbon emissions by 15 percent, according to the Department of Energy.

In addition to reducing emissions at point of use as main drawback of biofuels biodiesel fuel made from sources like corn, soybeans and other plants are known to absorbing carbon dioxide, when it was I the field. Industrial processes for the production of biodiesel are cleaner diesel than conventional procedures, cut down emissions to the life cycle of the fuel associated with more than 80 percent.

Energy Unit - Joule Calorie Conversion

In some occasion, it’s essential to measure how much energy measurement. For example, oil and natural gas companies need to have a way to measure the fuel takes of their customers so they can provide plenty natural gas when It's most necessary.

Numerous experimentations supported scientific approach, there's some form of energy measurement. A meter is an instrument that measures energy—such as the power and gas meters located on the sides of houses—and the standard unit of energy in the metric system is called a joule (J).

Energy can be measured in many different units. One calorie is equal to as the amount of heat energy unit needed to raise the temperature of 2.2 pounds (1 kilogram) of water by 1.8°F (1°C). Joule conversion to calorie: 1 Joule is approximately 0.2390 calorie. Power is simply the rate at which the energy is changed.

Energy can also be measured in units called foot-pounds. One foot-pound is the amount of work done in moving an object one foot against a 1-pound force. Therefore, if a 4-pound weight is lifted 6 feet off the ground, it's using 24 foot-pounds of energy.

Horsepower is another expresses energy. But it's a measure of power, not of energy unit itself. Power and energy is two different thing, power is different than energy. Energy is the ability to do work, on the other hand, power is a value of how quickly it's completed. Horse-power is used to value mechanical power. James Watt, a Scottish engineer, the first person advised the term of horse-power when running with invented steam engine.

One occasion, a doubtful farmer asked how many horses a steam engine could replace, this term was made up in place to make a reasonable equivalence. To measure it, Watt measured the amount a work a horse did in eight-hour period. Many types of power are now measured in units called watts (W). 1 kilowatt is equal to 1.341022 horsepower; this is as kilowatt to horsepower conversion.

Measuring Energy

Joule is the general unit in measuring energy. To cooling down a mug of hot chocolate at room temperature will free about 100,000 joules. The calorie is an old-fashioned unit often used to measure the energy contained in food. One calorie is comparable about 4,000 joules. Power is the value at which energy is given off or used, and most of the times it is then measured in watts. The use of 1 joule of energy every second is 1 watt. A 50 watt power light bulb uses 60 joules of energy every second to give off light and heat.


Physical units of measurement reflect measures of volume, height, distance, area,
force, impulse, and energy. Different kinds of energy are metered by various physical units: kilowatt-hours for counting electricity and tons for coal.

In order to do some comparison between different fuels, it is necessary to exchange the measurements to the identical units. In the United States, the unit of measure usually used for comparing fuels is the British thermal unit (Btu). British thermal unit is the number of energy necessary to enhance the temperature of 1 pound of water 1°F. One Btu is approximately equal to the energy released in to burn wood match.
