Cost = “carbon foorprint” = insustainable without oil or something-else to provide the energy to build it !! Currently it is simply more invasive “technology” but this time telling us that it is “green” – and therefore ok ?

Solar hot water undoubtedly has a Negative carbon foorprint in places such as here in Bulgaria , and quite possibly Solar photo-voltaic has too.

Wind energy, though, doesn’t Have to have a carbon footprint. Sailing ships and the Dutch polder pumps have demonstrated this, as I have – with a Turbine-Alternator device – TAD ? – which pays for itself in many locations after about 20 years, and in a good coastal location I would guess that maybe this would be reduced to 5 yrs. A “guilt-edged” investment by any standards. Meanwhile, the same people who talk of “Cost/kW-hr” (e.g. swea.co.uk) will tell us that the things pay several Hundred % of cost back PER ANNUM !!!

Whoa. 199,920 kW·h / $10,000 = 20 kW·h/$ -> 0.05 $/kW·h.

The levelized cost is 2–3 times that, because the construction cost is up-front while the average kW·h isn’t generated for a decade.

I saw pictures on the wepower site of turbines on a building like in Times sq for advertising and another attached to the bill board itself. If they were out in the open they might even work to some degree, but tiny turbines really don’t produce cheap power, only feel good token power. Now the giants produce power at least avg 6W per sq m when you factor in land but its dual use so thats okay.

I don’t really have a preferred energy source, I’ll take what works so I can forget. For now while we have growing renewables and fossil fuels and nukes they can work together. The problem is the CO2 emissions and then the fossil fuels will eventually go away in my kids lifetime.

Buildings use 40% of the nations electricity not 5. Plus these turbines can go in rural fields – what makes you think they are just for on houses.

If every single home in the UK or US and Timbuktoo had a $0 electric utility bill, it would take only 5% of the energy demand off the books, in other words it makes almost no difference unless you start working on the true energy bill of your lifestyle that is so out of site.
