Energy
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.
Resource
A resource is a source or supply from which a benefit is produced. Resources can be broadly classified on the basis upon their availability they are renewable and non renewable resources. They can also be classified as actual and potential on the basis of level of development and use, on the basis of origin they can be classified as biotic and abiotic, and on the bases of their distribution, as ubiquitous and localized( private resources ,community own ,resources ,natural resources ,international resources) .An item becomes a resource with time and developing technology. Typically resources are materials, energy, services, staff, knowledge, or other assets that are transformed to produce benefit and in the process may be consumed or made unavailable. Benefits of resource utilization may include increased wealth or wants, proper functioning of a system, or enhanced well being. From a human perspective a natural resource is anything obtained from the environment to satisfy human needs and wants. From a broader biological or ecological perspective a resource satisfies the needs of a living organism (see biological resource).
Energy
It is important to realize that in physics today, we have no knowledge of what energy is. We do not have a picture that energy comes in little blobs of a definite amount.
Richard Feynman, in The Feynman Lectures on Physics (1964) Volume I, 4-1
Energy
Our decision about energy will test the character of the American people and the ability of the President and the Congress to govern this Nation. This difficult effort will be the "moral equivalent of war," except that we will be uniting our efforts to build and not to destroy.
Jimmy Carter, address to the nation on the energy problem (April 18, 1977); Public Papers of the Presidents of the United States: Jimmy Carter, 1977, book 1, p. 656. Carter was quoting William James, who used the phrase in his essay, "The Moral Equivalent of War".
