Q 2. The following passage has not been edited. There is one error in each line. Write the wrong as well as the correct words.

Editing Exercise 1
More and more people in the country are looked
at the sun for cleaner energy options and right so
India receives a huge amounts of sunlight every
year. If harnessed with cost effective methods
this sunlight could be used to producing a whooping
600 giga watts of electricity. This is more than 5 time
the annual power consumption of India what
is only 120 giga watts. But in spite the fact that the
potential is huge, what India currently derive is
only 10-15 mega watts annually.

Editing Exercise 2
The most common utilization for solar energy
is been with solar photovoltaic (PV) cells. Here
the sun’s light is converting by the PV cells into
Direct Current (DC).These electricity can then be
used to running almost all gadgets in your home.
Another method involve the use of sun’s heat
instead of light. Energy producing from the sun’s
heat is called thermal solar energy. Producing
of thermal solar energy has more cost effective
then the photovoltaic cells method mainly because
here you can converts up to 50-80% of the sun’s
energy as opposed with PV which converts only 15%.
