Energy is the potential that we perceive we may use to accomplish a productive result.
If we want to go somewhere, we need energy to physically motivate us and to operationally propel a vehicle such as a car or airplane to move us there.
If we want to heat or cool our home, we need energy to operate some sort of device to raise or lower the temperature.
Energy is initially transformed by a chemical, mechanical, nuclear, solar, gravity, or any of the several transformers of energy. Once transformed from, for example nuclear energy into electricity, we need a device that can utilize that energy output, here electricity, to accomplish some desired effect.
This site considers several transforming methods, the costs of each, and the benefits derived.
There can not be prosperity without efficient and effective transforming devices producing energy adequate for achieving myriads of productive results.
