Yes it’s definitely worth it.
I guess you like the taxpayers being raped to support this nonviable program?
If you think it is "worth" it then why don't you advocate the removal off ALL taxpayer subsidies. Second, why don't you then invest your funds and see how viable it is after a few years. I would say you would be bankrupt.
You may think it is worth it, but it is immoral to use the "force" of government to take taxpayer funds to subsidize a product (windmill/solar to produce energy) that would not stand if left on it's own, especially when there are many alternative products already existing that provide energy at much lower unit costs.
