Additionally, research has shown that source credibility has an explicit effect on the bases of power used in persuasion. [7] Source credibility, the bases of power, and objective power, which is established based on variables such as position or title, are interrelated.
The mechanical power needed to assist in this production is provided by a number of different sources. These sources are called prime movers, and include diesel, petrol and natural gas engines. Coal, oil, natural gas, biomass and nuclear energy are energy sources that are used to heat water to produce super-heated steam. Non-mechanical prime ...

Power as a relational concept: Power exists in relationships. The issue here is often how much relative power a person has in comparison to one's partner. Partners in close and satisfying relationships often influence each other at different times in various arenas. Power as resource-based: Power usually represents a struggle over resources ...
National power is defined as the sum of all resources available to a nation in the pursuit of national objectives. [1] Assessing the national power of political entities was already a matter of relevance during the classical antiquity, the Middle Ages and the Renaissance and today.
Power is also used to describe the resources and capabilities of a state. This definition is quantitative and is most often [dubious – discuss] used by geopoliticians and the military. Capabilities are thought of in tangible terms—they are measurable, weighable, quantifiable assets.
Electric power flowing out of a circuit into a component is arbitrarily defined to have a positive sign, while power flowing into a circuit from a component is defined to have a negative sign. Thus passive components have positive power consumption, while power sources have negative power consumption. This is called the passive sign convention.
Renewable energy sources are even larger than the traditional fossil fuels and in theory can easily supply the world's energy needs. 89 PW [32] of solar power falls on the planet's surface. While it is not possible to capture all, or even most, of this energy, capturing less than 0.02% would be enough to meet the current energy needs.
