How is the sun the original source of energy for both coal and wind?

SOUMYADIP PAL, ST.XAVIER'S HIGH SCHOOL, HALDIA , EAST MIDNAPORE,WEST BENGAL,(INDIA) (CLASS--8A/3) ;- Because of sun the natural disasters are occurring and before 10000000 years from now, many plants and trees got buried and thus due to the long natural occurrences such as, decomposing and composting due to the action of bacteria and funguses resulting in the formation of coal.

Another fact is that, due to the hot and direct rays of the sun, low and high pressures are created alternatively and in this way, wind is formed.

hence, this is caused due to the presence of the original source of nature and that is :-sun
