Renewable energy

Are there places on Earth which could be powered exclusively by renewable energy with modern technologies? Places with four seasons (winter, spring, summer, autumn) and enough renewable energy at every season?

As far as I know, Norway exports its gas and oil as it has ample hydro-electricity.

The 'problem' is not the availability of renewables,
its the relative cost compared to fossil fuels.
There is more than enough energy available from Solar, Wind, Tide, Wave ..... power.

Polar regions don't have very much solar power in winter. Do they still have enough renewable energy?
(Subpolar Tierra del Fuego in South America has only little sunshine. Can they nevertheless produce enough renewable energy now?)

Iceland: geothermal, hydro, wind.

Cound Tierra del Fuego produce more wind power than the needed amount and convert it to fuels?
Could they create swimming pool, heated only by renewable energy (and chlorine produced from renewable energy as well)?

Brazil. I would suggest looking up some of the Ex-Patriot forums tho.

They are the leader in renewable energy but for garbage control, and general hygiene... pretty far down the list.

Also look at the cost of living. A 10. dollar blow dryer requires a "Pay-Day' loan to purchase at 120. dollars.
You would never dare just buy something, and eat it. BUGS are in everything... Ie: lettuce, corn, potatoes...

Brasil isn't polar or subpolar. Brazil doesn't have to rely on wind power in a season with little sunshine.

Supfanat, Whimsy please.

Did I tell you this was a forum about science? I was rong.

missing some variables. for what amount of people? doing/using the energy for what? watching tv? :) 100% electric for cooking, heating, cars...? today you can get 100% ren. energy but tomorrow a lot of people born and again you need more sources of energy. so again the problem start to root in the population control :)
fuck fuck fuck! :)
IMHO your question is very vague/esoteric.

I read some articles of places with 100% ren . energy, if I remenber good in islands in pacific. look in rense.com

but in ANY place you can get 100% ren. the PROBLEM is the moron idiots in gov's.

Germany is near 80-100% ren. energy.

Small scale hydroelectric is the solution to independent living.

Texas actually operated for about about 5 hours on wind energy alone. Http://www.slate.com/articles/business/the_juice/2015/09/texas_electricity_goes_negative_wind_power_was_so_plentiful_one_night_that.html
West Texas has wind energy all year around. They only need about 50% more windmills
To make up peak demand for the entire state. A moderate investment in solar would probably do the trick.
The key is storing the energy. Tesla is working on batteries that can do that.
In five years I think they will be there. Funny that one of the most anti renewable states is likely
To be the first to achieve renewable total power on the grid.

** many industrial plants in texas do not draw grid power because they generate their own
And use fossil fuels directly rather than electricity.

Vanadium Redox Flow Battery in use on a wind grid.

I want to see more of these.
(Actually, I want one for my house. With that and a few extra solar panels, I can go off grid even if there is two weeks of uninterrupted cloudy weather in winter.)

Yes sir, storage ability limited only by the size of your storage tanks.
