Exercise Basic 8.1-1

Exponential Growth

The output of the solar cell industry in 2006 - 2008 grew by 40 % per year. Let's assume that all solar cells installed in 2007 produced a total energy of 0.1 GW /year.
 
Calculate (and plot) the installed power as a function of time up to 2050 for growth rates of 20 %, 30 %, 40 %, and 50 %
What is the proper equation?
What follows from the results with respect to the world-wide power scenario as described in the link??
Plot the demand for Si, assuming that a standard (1000 x 1000 x 0.1) mm3 Si solar cell generates 10 W on average. Will there be enough Si? How do the amounts of Si needed compare to other essential raw materials?
