It would be interesting to find out what else there is for storing power.

Like what?

Something as simple as pumping water behind a dam, for use later, is low tech.

[Hans]

You use more energy to pump the water behind the dam than what the dammed water will provide to you. If not, you would have found an everlasting source of energy.

Of course you use more than you receive. That's not the point.

Any excess energy is used to turn the energy into another form, in this case gravity. It is stored as a potential. Energy can take many forms, and since perpetual energy is impossible, there are obviously losses during the transformation.

[Hans]

So you want to store 25,000 Terra-Watt of energy in a lake?

[Soundbear]

I dunno. How many terrawatts are stored behind dams in NorthAmerica now??

And there could be other forms of storage.

What is this? An episode of The Big Bang Theory?

I dont know, but these guys are completely overlooking the benefit of using dilithium crystals, to boost the signal.

[Hans]

It's a reality check. Current technology can simply not provide the power we need to replace all "unclean" energy.

Well, I don't know enough about it, and it seems like a situation specific to the region, but Iceland has solved a great deal of their energy issues using geothermal technology. I imagine it could be utilized elsewhere with some success.

Looks like we have about 30 years to figure it out.

Iceland is a small island, with a limited number of inhabitants. It's a land area that has a very high geothermal activity. So yes, they have a fair amount of geothermal energy that can be harvested with current technology.

When it comes to storing power, we have made limited progress in the past 100 years. The laws of nature are against us.
