Well, assume the Sun disappears from the Solar System tommorow.
The first effect would be that the earth is no more going around the sun and we do not know where we head next.
Because the sun does not rise in the morning ( the morning was because of the Sun anyway, now it will be by your clock) that the temperature drops drastically ( or let us say, never rises ). The birds sit confused.
No light .. 3 more days, water frozen no Electricity, .. goes on.
The earth getting cooled apart, you will see that the plants stop getting energy and the vegetable market would not work beyond the next three days and period! No more plant food. Which means just no more life.
This should be good for starters and we have not even begun. We are yet to get out of the "then what will be the erstwhile Solar System" and to some unruly climate of gases, etc which we are not used to ..
That should give you an Idea ..of the Sun, the light of our lives.
