With the growing problems concerning global
warming and climate changes, It is better to
find alternate sources of energy.

Use of alternate sources for energy such as the sun, wind
and magnetism has been present since years ago. It is used
successfully by individuals but not for large consumption.

The cost of producing free energy is cheaper than
produced energy. Examples of free energy are solar, water,
wind, centrifugal force, radiant energy, heat, hydrogen and
magnetism.

Use of wind energy and wind turbine generators is one of
the most reliable forms of free/renewable energy.

Another form is solar energy. Photovoltaic cells will
constitute the solar panels and will be responsible for the
conversion of solar energy directly into electrical energy.

The problem with solar energy is the cost of installing solar
panels since it is expensive and it can be affected by
clouds and air pollution.

The use of heat energy has been used by Nikola Tesla
before. He used heat from the air to generate mechanical
energy and called the device “Self-acting engine”.

Another controversial factor that can be used as
energy source is the sun’s and earth’s magnetic
fields.

Further studies are made to discover more
about the different components that can
be used to produced eco-friendly, safe
and free energy.
