Be Green! Build a solar power system

Yes, current PV panels are not that efficient and yes, they do cost a lot. However the energy collected is free...as in free. All this solar/thermal energy bombarding the planet day, day out and we're having debates about rebates, is it worth it, and so on?

I think the whole point of going "green" as they say is to reduce emissions...it's not just about efficiency. Efficiency is important in some aspects but what would people rather have? An "efficient" nuclear plant or a not as efficient solar/wind plant at their doorstep? How clean a technology is doesn't always relate to its efficiency. At least that's my opinion.

I'm not advocating this particular technology but I'm advocating that people not necessary destroy ideas with potential based solely on cost. Some of the most useful products used today were out of reach from everyone some time ago.
The energy received is free. It's unlimited sunlight and no one owns it.

The point being missed here is that let's say I pay $20K to install a solar powered system in home today. And let's say it pays off in 20 years. If the mass population of people became involved, there will undoubtedly be a reduction in pollution due to electricity now be created without the use of burning fossil fuels. In 20 years I'll have a solar system that has paid for itself, will now start making money for me, and has, over the long term, probably aided in the reduction of air pollutants related to electricity production.

Obviously there's an upfront cost and not everyone can afford it. But why don't we factor in the costs of our health and well-being in that case as well? Don't clean and water have and good health have any intrinsic value anymore? Probably not given the state of affairs these days.

Quarterly profits and long term benefits will go together so we have to choose what we want. So far, quarterly profits seem to trump all. If we take that approach, alternative energy and environmentally friendly products will take far too long to mature.
