Energy Production

2. a configuration of two water reservoirs at different elevations that can generate power as water
4. An energy source formed in the Earth's crust from decayed organic material
5. a class of Neutron which are said to be in 'thermodynamic equilibrium' which means they are moving with the same kinetic energy as their surroundings
6. those devices which are used to absorb the sun's rays and convert them into electricity or heat
7. energy per unit mass
9. electricity produced from generators driven by turbines that convert the potential energy of moving water into mechanical energy
13. the process by which the wind is used to generate mechanical power or electricity
14. the energy that's harvested directly from natural resources
16. a type of power station in which heat energy is converted to electrical energy
17. The sources which involve transformation process before final use
19. the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions
20. sources that will run out or will not be replenished in our lifetimes

1. The minimum amount of electric power delivered or required over a given period of time at a steady rate
2. a nonmechanical device that converts sunlight directly into electricity
3. the amount of energy that can be stored in a given system, substance, or region of space
8. a system used to transfer heat between a source and a working fluid
10. A rod, plate, or tube containing a material such as hafnium, boron, etc., used to control the power of a nuclear reactor
11. a medium that reduces the speed of fast neutrons
12. visualize material, energy and cost flows shown proportionally to the flow quantity
15. energy that is generated from natural processes that are continuously replenished
18. to increase the concentration or abundance of a component or isotope in (a solution or mixture); concentrate
