A renewable energy sculpture is an artwork that produces power from renewable sources, such as solar, wind, geothermal, hydroelectric or tidal. Such a sculpture is functionally both a renewable energy generator and a work of art , fulfilling utilitarian, aesthetic, and cultural functions.
Electrical energy is energy related to forces on electrically charged particles and the movement of those particles (often electrons in wires, but not always). This energy is supplied by the combination of current and electric potential (often referred to as voltage because electric potential is measured in volts) that is delivered by a circuit (e.g., provided by an electric power utility).
Electric utilities measure power using electricity meters, which keep a running total of the electric energy delivered to a customer. Unlike fossil fuels , electricity is a low entropy form of energy and can be converted into motion or many other forms of energy with high efficiency.

The efficiency of a conventional steam–electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle). The rest of the energy must leave the plant in the form of heat.
Dieselpunk is a genre and art style based on the aesthetics popular in the interwar period through the end of World War II into the 1950s, when diesel displaced the steam engine. The style combines the artistic and genre influences of the period (including pulp magazines , serial films , film noir , art deco , and wartime pin-ups ) with retro ...
A steam turbine used to provide electric power. An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area.
The vacuum energy, that is, the particle-antiparticle pairs generated and mutually annihilated within a time frame in accord with Heisenberg's uncertainty principle in the energy-time formulation, has been often invoked as the main contribution to dark energy. [23]
