  1. 3. energy obtained by harnessing wave power
  2. 4. renewable energy produced by living organisms.
  3. 7. the ability to do something or act in a particular way, especially as a faculty or quality.
  4. 11. the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
  5. 12. In the physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.
  6. 14. an electric charge that lets work be accomplished.
  7. 17. Tidal energy is a form of hydropower that converts the energy of the tides into electricity or other useful forms of power. The tide is created by the gravitational effect of the sun and the moon on the earth causing cyclical movement of the seas.
  8. 18. flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground (often in association with petroleum) and used as fuel.
  9. 20. relating to or denoting the generation of electricity using flowing water (typically from a reservoir held behind a dam or other barrier) to drive a turbine that powers a generator.
  10. 22. Radiant energy is energy that travels by waves or particles, particularly electromagnetic radiation such as heat or x-rays.
  11. 23. a brown, soil-like material characteristic of boggy, acid ground, consisting of partly decomposed vegetable matter. It is widely cut and dried for use in gardening and as fuel.
  12. 24. Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to produce electrical power, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.
  13. 25. a liquid mixture of hydrocarbons that is present in certain rock strata and can be extracted and refined to produce fuels including gasoline, kerosene, and diesel oil; oil.

  1. 1. Thermal energy is a term sometimes used to refer to the internal energy present in a system in a state of thermodynamic equilibrium by virtue of its temperature.
  2. 2. denoting things or parts made of a specified material or with specified tools.
  3. 4. the total mass of organisms in a given area or volume.
  4. 5. the energy released during nuclear fission or fusion, especially when used to generate electricity.
  5. 6. amount of energy that has to be transferred to or from one unit of mass (kilogram) or amount of substance (mole) to change the system temperature by one degree.
  6. 8. a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
  7. 9. A resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. Most fossil fuels, such as oil, natural gas and coal are considered nonrenewable resources in that their use is not sustainable because their formation takes billions of years.
  8. 10. radiant energy emitted by the sun.
  9. 13. Energy: energy stored in the bonds of chemical compounds
  10. 15. a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.
  11. 16. the action of dividing or splitting something into two or more parts.
  12. 19. the process or result of joining two or more things together to form a single entity.
  13. 21. energy that a body possesses by virtue of being in motion.
