Sounds interesting. Would you please provide more details. What was the former source and what renewables did you switch to.
I worked on a similar project 15 years ago and the particulars matter a lot. Normally it's a diesel replacement and diesel is brutally expensive in the bush. Solar is decent but that far north the panels are almost vertical! Summer is easy but winter was a non starter - we had to rely on fossil combined with geothermal heat pumps. Wind was a reasonable supplement depending on geography. I'd be curious to know the details of what they use in the winter as well.

Insufficiency has not happened since the 14 years it has been online (hydro power). The backup is a bunch of caterpillar diesel engines. The town is about 7500 people in the winter and 11000 in the summer.

Norway and Portugal are great examples of how it works on a larger scale. If it works for countries with 4 million people or 10 million people, I don't see why it wouldn't work on a larger scale. When it comes to renewables you need a nice variety. Storage needs to be sought in heat sinks rather than batteries. Most energy we use is heating homes and buildings.
Other than enviro nuts, are there people against hydro power?

Additionally, poverty rates are misleading. The World Bank and European Union define poverty as 50% of median income.
:LOL:
Fucking classic! Cite a statistic, then when it proves the opposite of what you thought it did, say "that statistic is misleading"

Dumbass.
Where else can you find entertainment like this?

I didn't cite anything. Poverty rates were brought up to me. How stupid are you? Yeah, don't answer that. We know.

I have seen prediction after prediction fail.
I'd like to see some examples. Give me a prediction, one that actually comes from a published study and tell me how it failed? 5 examples please, that is all I'm asking.

In the mean time have I personally seen with my own eyes that 75% of the arctic sea ice has disappeared. I'm only 41 years old.

Here's an interesting example of landscape level conservation efforts. I'm happy to see more of these projects taking off and finding some success, they're an important piece of the puzzle for adapting to a changing climate. Slowing the need to relocate businesses, communities, and infrastructure allows for more thoughtful future development and this is a relatively low cost way to do it.

You're right about hydro - about 90% of the world's 'easily available' hydro generation has already been developed. It was one of the first high ERORI systems deployed globally.
I'm of a different opinion. Just looking around here in Alaska I don't think that even 0.1% of the potential is used. I wouldn't be surprised if Alaska on it's own can provide enough electricity from hydro for the entire USA.

The town of Kodiak uses a combo of wind and hydro. They have an enormous flywheel for peak shaving. Other towns in Alaska do similar things.

My reference to Portugal is indeed hydro for a big portion, but it is supplemented with wind. When there is an excess of wind power, it is actually used to pump water back into the reservoirs to be able to use it as hydro again later on if there is no wind.
There are so many options to store energy, batteries are not necessary.

On my boat I use a 1200L heat sink that can heat the boat. When the engine has run for a few hours, it has stored enough heat to keep the boat warm for a week.

That is one of my problems with all the so called 'energy experts'. Thinking out of the box is not something they are comfortable with.

Another example. I built a salt box that fitted around the exhaust manyfold of my car. The salt absorbs a lot more heat than water does. When coming home I placed that box in a specially made heat exchanger at the beginning of the heating loop of the central heating system. 1 hour of driving stored enough heat to heat the house till the next day. Heating bill went down with about 70%. It was a fairly inexpensive prototype that worked for a couple of years. I abandoned it because I switched to an electric car and a heat pump in my house. These things produced on a mass scale can be dirt cheap but somehow nobody offers these kind of solutions.
Any combustion engine throws 70% of the energy from the fuel straight out of the exhaust pipe. After only half of the fossil fuel actually reached the car to start with (the rest is used by the oil industry to get refined products to your local gas pump).

Think outside the box people, it is not all that hard.
Somehow the focus also seems to be on how to generate the energy, but I see ridiculously little effort in saving energy, especially in the USA. Every kWh (be it electrical or otherwise) that is not used does not need to be generated. That is a part that is totally lost in most discussions.

I think you meant to say that 70% has disappeared in 40 years during the summer minimum. You were there measuring the ice with a ruler when you were 1? That is pretty impressive.

What fuel does that engine burn, and what is your hull made from?

And that, my friend, is why I will stop discussing with you. Your comprehensive reading skills are basically non-existent.
