What companies are the best in supplying Alternative Energy Generators(Solar, Wind…)?

Hello,

I was wondering if one day I wanted to buy good products for generating energy from alternative resources like the Wind power and the Solar power, which companies are the best in supplying those kinds of generators?

I’m not just thinking of small generators for homes, I’m thinking of a bigger level too. Like for big industrial companies or even National level!

Thanks a lot for your expertise exchange 🙂

What do you think would happen if a virtually free source of energy was discovered?

If individuals and businesses suddenly became self sufficient in terms of electricity and transportation, lets say an ultra efficient solar or fuel cell was developed, how would the government compensate for the sudden massive loss of tax revenue? Would they tax the production and ownership of such an energy source at such a rate as to make its ownership financially prohibitive? Would they follow Oregon’s example with their planed requirement of GPS units in cars, tracking the distances you travel, then tax you for every mile you drive? Would some sort of meter be required on every solar array or generator in homes and businesses?

What do you think the political and economic repercussions of such scenario would be?
@cob bollum “it will never be completely “free”, it’s physically impossible.”
I’m not suggesting a way around the laws of thermodynamics. I said ultra efficient. An ultra efficient way to capture the suns energy and store it for instance would be a source of “free” energy, other than it’s initial purchase and any maintenance required.
@James L Those are my thoughts as well, however I do not see government giving up their control so easily despite the economic windfall such a development could precipitate. Perhaps i’m a pessimist, but I do not see them trading control and revenue for just more revenue, even if that revenue had the potential to be much greater.
