Don't you find it amusing that free energy is easy to find on the internet? Perhaps you could convince municipal authorities to implement the concept in a world first "pushing s$!t uphill" sewer? It would complement the renewable energy strategy nicely.

Yes, hydroelectric storage is the cheapest by far, but it has physical limitations, and building storage dams, if possible, would increase the cost. Do you think the Greens might be interested in damming the Franklin to help fight climate change?

The problem regarding anything in our society is profit. There are lterally dozens of solution regarding energy but because of demands for profit most become unviable.
What's needed are Govt run schemes that focus on sustainability rather than private/corporate schemes that require excess profit.
The private/corporate sector has become a self-devouring monster for which there are no animal trainers.

Pumped hydro, like hydrogen, needs more energy to produce than it puts out.

Wasn't that what communism was supposed to demonstrate? The problem communism and renewable energy share is one of the ideology blinding you to the reality.

FYI I'm all for coal.
Coal allowed me to live a life above that of a neanderthal.
These greenies want to take us back there.

The US has given Ukraine 57 billion dollars in aid since the war in Ukraine began.
I remember seeing secondhand solar panels on gumtree for AUD$40 each less in bulk with 90 - 95% output.
- So lets say USD$30 each.
57 thousand million divide by $30 each = 1 billion 900 thousand solar panels. 45000+ megawatts,
10 times more than we need on the entire continent.

I've seen so fairly creative and ingenious ideas.
We're in an age where 3D printers and robots could manufacture most of the stuff we need, but sure labour is always going to be a factor.
That's actually a benefit as it keeps human beings useful.

Water is the single most important resource on the planet.
Most of it flows through pipes why not harness the energy from the flow?
There's no end of better ways we could do things, if we actually wanted to.

We could generate power from many different sources.
If you wanted to pump crap uphill, we could put small turbines in those pipes and generate energy from that too.

Apparently bombs are more important.
Or bombs to conquer land and control oil pipelines anyway.

"Following the Orange Revolution and the election of Yulia Tymoshenko as Prime Minister who on March 5, 2005, announced that the oil would flow from Brody to Europe, Ukraine opposes Russia's plan.
On 24 March 2010, Ukraine's ambassador to Belarus proposed the pipeline begin operating in the averse direction in order to deliver Venezuelan crude to Belarusian refineries.
In March 2020, Ukraine resumed transporting oil from Brody to Belarus and Poland."

"Some have proposed that the actual motive for the United States-led Western invasion of Afghanistan in 2001 was Afghanistan's importance as a conduit for oil pipelines to Afghanistan's neighbouring countries, by effectively bypassing Russian and Iranian territories, and breaking the Russian and Iranian collective monopoly on regional energy supplies."

What about Syria?

It's all about pipelines.

Sorry I meant 1 billion 900 million solar panels, my mistake.
