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%.
