The sun sends more energy to the earth every day then humans currently consume. The problem is that we are unable to capture more than a small percentage of this energy.
Pure economics. It costs more to use "non-conventional" energy sources.
First of all, that's not entirely true. It is only when heat energy is uniformly spread out (different objects have the same temperature) that it is unusable. If heat is concentrated in one place, part of the energy can still be used.It is a fundamental law in our Universe, that there are irreversible processes. The reason for this is hard to understand, but scientists have a measure for this, a rather abstract quantity called "entropy" - and the way it is defined, entropy will always increase in any process (or, in the borderline case, not change, or hardly change) - but it can never decrease. It has been found by experience, and by many thought experiments, that no such process exists.

The electrons in an electrical current are not used up by the current. They are simply moved. A simple way to think of the current is as a stream of water, except that in the current it is electrons that are flowing, not water molecules. When the energy in a water current is tapped - by a turbine, say - the water molecules are not destroyed, although the turbine obtains energy.In principle used ("converted" would be better) electrical energy could be changed back into electrical energy, except that some of it will be forever lost as heat. This energy has not been destroyed, merely converted into a form where it can do no useful work. This is an inevitable consequence of the second law of thermodynamics, which applies to all energy conversions, not just electrical ones.
The giraffe is the tallest of all living animals; however, scientists are unable to explain the origins of its long neck. (sorry, the first sentence was awful)

Scientists still hope that Mars may have life of some kind; it would be an exciting discovery!Some reasons why Mars is unable to form EARTH life forms would be the lack of an oxygen atmosphere and the lack of water except possibly as ice in the polar regions.
They believed the exercises they performed made them unable to be harmed by bullets. Bad choice.

Yes. Hurricanes gain energy from moisture that evaporates from warm ocean water. A hurricane could never develop if it were unable to gain energy.
