How much energy is given out by the sun per second?
1 million ton of energy per second
How many BTU per ton of coal?
20 Million BTU ****************** The heat content of coal varies. Bituminous coal typically has a gross heating value of 30,600,000 BTU per ton. The net heating value is 26,000,000 BTU per ton, assuming 85% efficiency. If you need more precise information, go to the U.S. Department of Energy website at www.doe.gov and search on the heat content of coal. -ecn
How much energy is used per kilogram?
More information is required. What energy is used in what process, per kilogram of what?
Does coal give off the most energy?
In short, No. Coal comes in the middle of the pack when fuels are compared. Propane produces 21500 BTU per pound, Gasoline 17500 BTU per pound, Coal between 12,000 BTU per pound (Anthracite) to 10,000 BTU per pound (Bituminous) and wood (dried) 7000 BTU or so. On the other hand, Coal can be converted to Gasoline using a process developed during WWII, or to Methane (modern) or to "Town Gas", a mixture of Hydrogen and Carbon Monoxide.
How much does wind energy cost per joule?
It Costs $5.00
How much energy does coal give out?
21-22 gigajoules per ton
Uranium fuel pellet used in nuclear power stations produce far more energy per kilogram than the energy produced by burning coal How much coal has to be burnt to produce the same amount of energy as?
1 kg of U-235 will produce as much energy as 1500 tons of coal
What is the energy content of coal?
6.5 kJ per 250 g of coal
What is the highest grade of coal that produces the least pollution and most energy per unit?
Anthracite is the highest grade of coal that produces the least pollution and most energy per unit. It is also known as stone coal, or black coal.
Uranium fuel pellets used in nuclear power station produce far more energy per kilogram than the energy produced by burning coal How much coal has to be burnt to produce the same amount of energy?
1 kg uranium 235 = 3 000 t coal
What produces more energy coal or gas?
For this the proper metric for comparison is the energy density of the fuel. Coal: 6.7 KW-hr per kg Natural Gas: 14.9 KW-hr per kg. So natural gas produces more energy per kg than coal.
How much does coal cost per kwh?
Coal cost about $o.o54 cents per kwh
How much does nuclear energy cost per joule?
See the attached link below for a survey of the economics of nuclear power
How much is coal worth today?
Coal comes in many types - for many uses. Thermal Coal: Primary for Power Generation - can be as affordable as $13.25 per ton Metallurgical Coal: Primary for Manufacturing Cost as much as $300+ per ton Difference: Based in the energy content measured in BTU's - British Thermal Units Low: 8,400 Btu's per Pound High: 15,000 Btu's per Pound Most often thermal coal cost less than Rail Road rates to carry the coal to power plants / other facilities
How much energy can be obtained by burning coal?
An average energy density of coal is about 24 megajoules per kilogram. This is the equivalent of about 6.67 kW·h of energy per kilogram of coal, However with the various energy transformations in the power plant (coal to heat, heat to steam, steam to mechanical movement of the turbines) and the loss of heat to the air water and solid waste less than 30% of that will become electricity. Lines losses and user losses will reduce this even further if end user available power is calculated.
What kind of energy does coal produce?
A coal plant can produce different amount of energy. It depends on the size of the plant.
How much coal is needed to produce 1kw of electricity?
The energy density of coal can also be expressed in kilowatt-hours for some unit of mass, the units that electricity is most commonly sold in, to estimate how much coal is required to power electrical appliances. One kilowatt-hour is 3.6 MJ, so the energy density of coal is 6.67 kW·h/kg. The typical thermodynamic efficiency of coal power plants is about 30%, so of the 6.67 kW·h of energy per kilogram of coal, 30% of that-2.0 kW·h/kg-can successfully be turned into electricity; the rest is waste heat. So coal power plants obtain approximately 2.0 kW·h per kilogram of burned coal. I copied it from wiki page see the same for clear view http://en.wikipedia.org/wiki/Coal regards Raghs
