> a low-cost wind turbine that can generate 3-5 kW hours of electricity every day I'd say it's for a very narrow definition of "a house": https://www.eia.gov/tools/faqs/faq.cfm?id=97&t=3 https://www.eia.gov/tools/faqs/faq.cfm?id=97&t=3 I guess it could work in India, but households in most developed countries spend much more energy: http://shrinkthatfootprint.com/average-household-electricity-consumption http://shrinkthatfootprint.com/average-household-electricity... BTW, much better article here: http://economictimes.indiatimes.com/news/politics-and-nation/avant-garde-innovations-develops-wind-turbine-to-light-up-homes-at-a-fraction-of-power-bills/articleshow/53015680.cms http://economictimes.indiatimes.com/news/politics-and-nation...

In the context of the article - India - it seems spot on. Additionally, energy use in western homes has fallen dramatically in recent years. We've gone from 100W bulbs to LEDs and from big vacuum cleaners to small robots and even fridges, freezers and washing machines have been using less and less each generation. Hopefully electricity use will pick up again slightly as we all start charging our cars at home, and that will be a good thing from the total energy usage and environmental perspective. PS you edited your post and added all those links and mention of India only after I replied ;)

Households in the USA (and Canada) are outliers in home electricity use, using about 40% more than numbers 3 and 4 (Australia and France) and double that of number 5 (Japan) in the list at http://shrinkthatfootprint.com/average-household-electricity-consumption http://shrinkthatfootprint.com/average-household-electricity... (I think that list is complete for the top 5, but am not sure)

  It still isn't enough to power an average world's household. 3,500 kWh/year is about 9.5kWh daily and this turbine can only generate up to 5. It would only work in India, Nigeria and China, and only if you have good weather conditions. For all the other countries it still isn't what the title says.

    "India, Nigeria, and China" is over a third of the world's population, and even in countries with higher _average_ electricity consumption, there will be households where this would be sufficient.
