Because non-renewable means they will run out. If we run of of energy we're in trouble. So we need to use renewable sources, ones that will not run out, in order to meet our energy needs. Also, renewable sources tend to more environmentally friendly to use.

because non renewable resources eventually run out (hence the name, nonrenewable). In order to make the inevitable switch, we must slowly wean ourselves from "fossil fuels", that's why it's so important to start the switch now. Also renewable sources generally don't cause pollution.

In very short term, non-renewable sources such as coal and oil are fast running out.
