Question

Total power generated by wind worldwide doubles every 3 years. In a particular year, the world wind-generating capacity was about 91 thousand megawatts. Find the continuous growth rate and give a formula for wind generating capacity WW (in thousand megawatts) as a function of tt, the number of years in the future.

Answer 1

You are given the sum of the power created by wind worldwide which doubles every 3 years. In one an unknown year, the world wind generating capacity was about 91 thousand megawatts. You are asked for the growth rate. the growth rate formula is given below:

growth rate = (present / past)^(1/n)
2 = (present/91MW)^(1/3)
the present power is 728MW
