It is not as much about loosing money as it is reducing our standard of living. Standard of living is ultimately determined by the cost of living versus what our individual wages are. If energy prices went up 300%, the effects would be rather striking because all prices would increase as a result.
In short... Solar energy is not a viable option as long as petroleum reserves are so plentiful. Most are expecting that we will shift to natural gas before solar energy because viable..
Good Luck and I Hope this Helps..
