The short answer is 'No'.

Bill Yenne, in his book The World's Worst Aircraft wrote, "Like any great technological leap with a timetable set by politicians, (it) takes longer than expected to evolve" It fails anytime it is "really more a political venture than an economically justifiable commercial one."

In the 1980's, when the global cooling scare ended because of global warming, the alternative energy companies died.  They could not survive without the tax money they received in the form of 'aggressive tax deductions'.

Thirty years later, alternative energy still cannot stand on it's own.  It still cannot produce cost competitive power.  Only by offsetting a majority of the cost through tax breaks and energy company rebates can alternative energies come close to competitive.  Without the rebates, the industry will be left to the real environmentalists.

The challenges that come with the end of the alternative-energy industries are predictable.  The alternative power equipment now being sold will have a challenge being serviced. 

Solar panels on roofs must last longer than the roof to yield the promised return.  That means the solar panels will need to be removed and reinstalled sometime in the future.  If the solar industries are out of business, who will do the service?

The 'wind' industry will not be affected as much.  Partly because more of it is commercial and has service contracts in place.  Also because the return-on-investment is high with wind.

Someday, alternative energy will be commonplace.  People have been trying for decades.  But that day may still be decades away.
