For electricity it is still coal, at about 50 percent. For transport it is oil.
Very much so. Mining is the only source of metals and minerals, and the source of much of the energy used in a country.
Mechanical and Electrical
uranium is nuclear energy's source it is mined in areas like Canada, Brazil, Australia and etc that's all I know hoped it helped :)
Wind energy is a natural rescource made by harnesting it's power threw a wind turbine. Coal is the dirtiest source of energy releasing sulfur and cabon monoxide into the atmosphere.
Principal is a legal term. The principal is the person or entity who hires another(via contract) to perform a task on the principal's behalf. These people are called agents. Therefore: Homeowner= Principal hires the... Real estate "Agent"
the sun
SUN
well htey get there energy from burning the gasses that it is made of like our sun
Since the sunis the principal energy source for atmospheric processes, it is critically important. Without the sun, not only would those processes not exist, but the atmosphere would condense and freeze and the planet would be uninhabitable by the forms of life that now exist on it.

The principal fuel source for living animals is monosaccharides.
Nuclear energy is used as a source of heat. The heat from the reactor is used to heat up water and the steam moves a turbine that generates electricity. It's the same principal with a coal power plant, only the source of heat is different.
"I refuse to lie as a matter of principle." This word is often confused with, "principal," which means "main" or the head of something, like a school. For that you could say: * The principal called me to detention * Oil is the principal source of energy in the world today
The orbital will be described with a number, followed by a letter, which may have a suffix. The number is the principal energy level. For example 2p, principal energy level 2; 5d principal energy level 5; 1s principal energy level 1.
There are 2 energy sublevels in the second principal.
Principal energy levels are an atom's major energy levels, ranging in value from 1 to 7. Energy sublevels are contained within principal energy levels, and their number increases as the value of the principal energy level increases.
