### energy:

Nuclear energy
* Most nuclear energy becomes energy.
* Most nuclear energy has effects
  - harmful effects
  - is made from the atoms of uranium
  - produces heat
* Nuclear energies are much higher.
* Some nuclear energy comes from forces
  - strong forces
* Some nuclear energy produces materials
  - radioactive materials
* can be quite useful or violently destructive
  - cause environmental problems
  - provide an essentially unlimited supply of economic energy
* comes from mass.
* comes from the strong force
  - tiniest building blocks of matter, the nuclei of the atoms
  - in two forms, fission and fusion
* constitutes the major alternative to coal in the future for the utility industry.
* form of energy derived from the radioactive decay of uranium.
* great energy source for all of mankind.
* has also gain momentum
* helps keep our economy strong and our air clean.
* is also one of the cleanest ways to produce electricity
  - safest sources of energy too
* is an important source of electricity in the United States-it's second only to coal
  - unforgiving technology in the middle of a densely populated area
  - beneficial for the environment
* is clean because of the large amount of energy released per fission
  - contained within the center of the atom in a place known as the nucleus
* is created by tinkering with the atom, a fundamental building block of matter
  - when atoms of uranium are split by fast-moving neutrons
  - depicted as an energy source until other sources can be developed
  - essentially emission free
  - fueled by uranium, also a non-renewable resource
  - humanity's best hope for the long term
  - important on Earth too
  - literally a renewable energy source
  - much cleaner than other forms of large-scale energy generation
  - no where near the limited resource that fossil fuels are
  - one alternative to fossil fuels
* is one of the cleanest sources of energy known nowadays
  - momentous discoveries of our times
  - probably the most efficient way of creating thermo-electricity
* is released by splitting the nucleus of the atom into pieces
  - the splitting of the nucleus of an atom
  - the cleanest type of energy that has no health consequences
* is the energy in the nucleus , or core, of an atom
  - present in interactions among particles in an atom's nucleus
  - produced in the nucleus of an atom
  - released when nuclear reactions take place
  - most heavily subsidized form of energy of any energy source
  - only source of power in the future
* is the stored potential of the nucleus of an atom
  - nucleus, or center, of an individual atom
  - uneconomical compared to other sources
* is used by many countries in the world
  - in what mathematicians call an existence proof
  - very important for someone s safety
* latent form of proliferation.
* needs to be part of the global, clean energy mix.
* offers the world a clean, stable source of energy for heat, light and power.
* plays an important role in avoiding greenhouse gases.
* popular way of generating electricity around the world.
* poses the unique threats of radioactive waste and radiation.
* produces electricity when tiny particles of matter are split apart
  - fewer pollutants than any other energy form
  - twenty percent of our electricity in the United States
  - very small amounts of waste by volume
* provides about one third of the country's electricity
  - for power to run cities and medical treatment to heal diseases
* relatively new but very important energy source.
* remains a safe, reliable, and economical source of electricity.
* threatens to maim or annihilate future generations.
* uses special radioactive materials to make electricity.
* way to generate power by harnessing the energy stored in the atom.

Photon energy
* function of the frequency.
* is directly proportional to the frequency of the electromagnetic radiation
  - inversely proportional to wavelength
* seems to be the energy of the future.
