Topic: SOLAR ENERGY ? - page 3. (Read 3751 times)
How much is the price for PV or a mixt PV+Wind solar system in the USA or EU countries? In Romania is around 3 Euro per watt. However, there are better ways than just buy expensive photovoltaic systems; we work on this now. After testing I will be able to come with the results so pls let me know if there is someone interested. You also can PM me. We use them for our eco energy efficient houses built in RO and in some EU countries.
Help the environment for sure!
Oh, man, how can you bash Minnesota like that! I love the north woods!
But I don't live there, so it's a treat to go for me. 
Anyway, there are a lot of places, of course, where solar is not as cost-effective. You really need dry, desert areas. The southwest part of the US would likely be the best place in the country.
I love the north woods too:P
Its been a rough year this year, 8 straight weeks where the high temp was 0 degrees, up to -30 degree lows during that with windchill of -55 degrees...
Then to follow that up it snowed until May, afterwards it rained for 2 months and flooded every river and we were still unable to go outside...So far we have had 1 day where it reached 90....Now Summer will be coming to an end very shortly and you can barely enjoy it!
I thought you might find this December 2013 article interesting: http://www.computerworld.com/s/article/9244836/Solar_power_installation_costs_fall_through_the_floor
Particularly this part: "The cost of installing photovoltaic solar arrays has dropped to $3 per watt of electricity they produce - about the same as coal-powered plants cost to build ..."
So it sounds like the cost is quickly becoming less of a factor.

Well that is pretty darn interesting, I didn't know that!
If it keeps going like that it would be great, although I live in a crappy part of the states where I don't know if we could successfully use it because we don't get enough sun! Stupid Minnesota!

Solar energy is environment - friendly.
Solar energy shouldn't even be in the convo at the moment. It is far to expensive up front and doesn't return your investment until way later of in the years.
I often see this posted on social media about how we need to convert roads to solar panels. It is a great idea....however if we were to do that to just 1 state(larger state) the country would probably double in debt and its already hard to see us getting out of this whole(USA). Think about redoing the world...

You know what? I once saw satellite picture of Sahara Desert. There were staged solar collectors on like 1/10 of that desert and descriptions: If you put solar collectors on part of Sahara Desert it will generate energy sufficient to power whole world. Now I am wonder why people does not do that?
Three reasons: up-front cost, inability to transmit electricity very long distances, and cost of nighttime energy storage.Wikipedia (http://en.wikipedia.org/wiki/Electric_energy_consumption) says that worldwide electricity consumption in 2008 was 20,279,640 GWh. Even if you make an optimistic assumption of 12 hours of perfect sunlight per day and $3 USD/W installed in 2013 (so 365 x 12 / 3 = 1460 Wh/yr/USD), that would still be 20,279,640,000,000,000 Wh/yr / 1460 Wh/yr/USD = $13,890,164,383,562. So $14T.
You can transmit electricity for a number of miles, but the farther it goes, the more you lose due to resistance of the power lines.
And you need a huge amount of electrical capacity (batteries) to store such large amounts of power for nighttime use.
what if gov rise charges on non-green energy ... what the impact would be ?
That would help green energy. But the government won't do that, at least not in the US. There would be a huge public outcry if they tried. Plus, the government is in bed with the oil companies, so there's no way they will anyway.Sad, we live in

Unfortunately, if we stick to "we can't afford this now," then it will never happen. Solar energy is not the full answer anyway. It's just one of a number of clean energy sources that needs to be developed. Like many technologies, the more solar is used, the more incentive there is to research improved cells, which will further bring down the cost. Additionally, it's very likely that fossil fuel energy sources will continue to increase in price. Solar may be more expensive now, but further development will make it cheaper in the future.

i'd love to install solar pads on my home, but for now, it's really not cost effective.
Tell me cost of hot water for 5 Years in Your Home
I have now 150 liter of water at 71 C° for free. And in Summer is normal 90-97 C°.
If I would try to do that I would have 150 litres of ice for most of time

I am pretty SURE my electricity meter is connected to a Stratum 0 devices, and is nuclear powered ... how can we audit it ? I mean how to know my meter is really showing the proper measurement ?
I would be enlightened by the sun with a miner device 99.999 sun's nuclear fusion ( Our star, the Sun, makes up 99% of all the mass in the Solar System.) powered.
