what type of energy does the world use?

Answer 1

Well, the short answer is "all kinds." It's a bit more complicated though since some forms of enery are not readily transported. Potential energy, for example, is stored in the water behind a dam. However, we can't just move a dam to places where we need energy so it has to be converted to another form that we CAN transport: Electricity. Natural gas could be used in the same type of example. It is piped all over the world from some pretty far away places. When it gets to your house, the oven or water heater burns it to give off heat. Nuclear energy is another type that has to be converted to be usable. The heat given off by nuclear fuel is used to heat water (or some other substance) into steam in a nuclear power plant. This steam is used to turn a turbine which generates electricity. One last source of energy I will mention is the sun. Light energy is so plentiful that in just one hour, more light energy hits the surface of the earth than the entire world will use in a YEAR. (That is why there is a big push to get solar electricity technologies working better now days.) The big issue with energy is turning it into a form we can transport and/or use, but there are many sources of energy for the world.

Answer 2

It's a combination of forces, but, mostly gravity. A phenomena known as the precession of the equinoxes has been observed for millenia by people with an interest in the mechanisms governing the universe, this phenomena is responsible for why the same stars do not appear in the sky at all times, why the sun rises higher in the sky during summer, why the days are shorter during winter, etc. Basically, the earth is rotating around the sun in its elliptical orbit because of the force of gravity, as everyone knows. A lesser known fact is that the sun's pull on the earth combined with the centripetal force of the earth's spinning on its access causes the earth to bulge slightly at the equator. The axis, either due to the elliptical orbit and the earth's malleability or due to the fact that it is very possible that our entire solar system is moving through the universe and is not stationary, wobbles, like a spinning top on the floor, and this creates the changing views of the stars, moon and sun that we have from our vantage on the earth's surface. As far as what kind of energy drives the world round the access, well, there's two answers that don't really answer the question: first, conservation of mass in the universe, meaning matter is neither created nor destroyed it merely changes forms and shapes, etc., second, conservation of energy, energy is not created or destroyed, either. Thus, we have energy that comes from momentum and gravity and the like physical forces, and we have energy that can be observed in endothermic and exothermic reactions etc, thermodynamic energy. But, if you ask me, that doesn't account for conscious energy at all, and i think that conscious energy is probably a major factor in the ways things work, too...In short, Yes, i do wonder...
