Design
Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to use design thinking.
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.
Renewable Energy
Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.
Integration
Secular humanism contrasts with religious humanism, which is an integration of humanist ethical philosophy with religious rituals and beliefs that center on human needs, interests, and abilities.

Integration
There are a number of standard procedures which can enable a large number of common integrals to be evaluated explicitly. The simplest strategy is integration by substitution which means changing the variable of integration.

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".
