Nanotechnology and photovoltaics. There's only one source of renewable energy that can provide all of the world's needs and that's the Sun. In fact, enough sunlight falls on the Earth's surface in just a couple of hours each day to meet the whole world's energy needs for one year.

Gravitational Force and Electromagnetic Base

Until a few years ago scientists believed that all forces could be categorized into five classes:

  • Gravitational force - the force of attraction between any two objects with mass.
  • Electric force - a force of attraction or repulsion between charged objects.
  • Magnetic force - a force of attraction or repulsion between ferro magnetic objects.
  • Strong force - the force holding protons and neutrons together in the nucleus.
  • Weak force - the force which causes radioactive decay.

In recent years it has been shown that the magnetic, strong, and weak forces are all variations of the electric force now called the electro-weak force. Many scientists believe that the gravitational force may also have an electromagnetic base, but no proof exists as of now.
