piezoelectric:

it is a natural crystal made of lead zirconate titanate . when this crystal exposed to pressure or motion the structure gets disturbed and producese charges which we convert to electrical energy.

advantages:

environmental friendly

cost effective

benefits from a wasted energy from traffic

# data[].attributes.body
WINDENERGY:

wind energy is a form of solar energy. Wind energy (or wind power) describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. A generator can convert mechanical powerinto electricity.

Cons :-

- Clean source

- Renewable

- Cost effective

- Extra savings for land owners

- Use of modern technology

- Rapid growth and huge potential

- Can be built an existing farms

SOLAR POWER :

Solar panels absorb sunlight and using photovoltaic cells,turn it into electricity.

ADVANTAGES:

-inexhaustible

-zero pollution

-can be adapted to work on a variety of buildings/in a variety of environments

DISADVANTAGES:

-can only be used in sunny parts.

-can only operate for certain times of the day.
