what about Hydro?
It's ok but it can cause a lot of environmental damage if it's not done properly, there aren't that many sites left in the UK to put it as the easy/good ones are already done and it's on a par with offshore wind in the cost stakes.are there quite strenuous requirements around the flow/speed of water required?
I'm not current (no pun intened) on the precise requirements of the different types and designs of hydro, more on the "non-polluting" (not quite) / "environment impacting" aspects
maybe not as big as the hydro plants in scotland I have seen, but surely this is a perfect way of gaining energy. Something that we managed to get working 150 years ago without the technology we have now!

Being up in the pennines, we have literally thousands of old dams on our rivers. Mostly crumbling away and all unused, they used to provide the power for much of the industrial revolution around these parts.

Can you guess why we abandoned it? Go on, get the old grey matter working.maybe not as big as the hydro plants in scotland I have seen, but surely this is a perfect way of gaining energy. Something that we managed to get working 150 years ago without the technology we have now!

because they didn't have turbines and generators, or an electric grid back then.
Sorry, I fail to see your point.

Much the same with steam railways, shame about the Government ripping out rail links.
Much the same with the trams.
OK it's small beer compared to hydro dams but sometimes we can learn from history, but not our Governments, sadly.

There's a really great and interesting episode of The Tweenies (no, really!) where they go inside a Scottish Hydro station carved deep inside a mountain. maybe not as big as the hydro plants in scotland I have seen, but surely this is a perfect way of gaining energy.

Solar lost out to fracking primarily because of floor space being used up.
If you put them onto building roofs then the biggest negative for solar in that diagram disappeared.
In part, but only part. In this country solar power lost out because, well, it's not very good here. Darkness, snow, heavy rain etc all affect panel performance. If you put them onto building roofs then the biggest negative for solar in that diagram disappeared.
It's OK for heating a finite amount water ( a bit like turning your immersion heater on before taking a bath) but for providing usable energy to drive other household and industrial requirements 24/7 it's about as much use as a chocolate fireguard.
Part of the issue is how to store excess energy, particularly energy generated from renewable sources. At present we can't do it very well - aside from simple schemes such as pumping some water up a mountain or such like to let it fall back down we need power and the renewable source is offline -
Battery technology is not there yet, and despite many promises it looks like it won't be there for a while to come.
One interesting proposition is to take excess renewable energy and use it to convert something into a storable fuel. I am aware of at least one project that involves taking CO2 and converting it to CH4 using excess renewable energy to facilitate the process.
Solar has some fine purposes, but mass-power generation to feed into a national grid isn't really one of them in the UK.
Sticking them on peoples roofs to generate hot water on the other hand seems like a good idea.
My dad has some random glass tube things on his roof and doesn't need to heat any water in summer. He installed them himself. He also plumbed in his cast iron fire which he feeds wood in winter, so that heats his hot water in winter.
That is very localised joined up thinking and it works.
But I can be pretty sure that the big energy companies don't actually like this because they're losing out from being able to basically give you back what you generate (solar on your roof with feed in tarrif) with some value skimmed off.
Which is where we are failing with policy generally. Big centralised power generation/distribution doesn't work with these small novel power generation ideas.
And so big power companies only want stuff they can profit from. But that is backwards unless they're willing to actually put their money where their mouths are and invest in something for the long term that actually works.
Fracking won't last for the long term. We need investment in stuff that works!

Nope, they had switched to coal/steam a century earlier. Guess again.
no they didn't. not where I live.in the cities yes, but not here. cotton and wool mills were powered by water wheels/mill ponds until the trade came from abroad.
but still you have ignored the important part. they did not have the technology to produce electricity and put it into the national grid then!!! They were used form something completely different.
The funny thing about this is that hydro electric power generation has caused serious earthquakes where as fracking has not.

What? You had operating water driven mills in the 1950's? Wow.in the cities yes, but not here. cotton and wool mills were powered by water wheels/mill ponds until the trade came from abroad.

I haven't missed the important part, you have. The reason they stopped being used is because coal/steam plants meant that mill owners no longer had to be tied to building mills in difficult hilly locations with poor transport infrastructure and could now do the same thing in a town or city on the canal and latterly rail network and therefore have much better access to their markets and labour. There was another reason too, droughts and floods; I know the BBC would have you believe that these phenomena only happened after 1980 but there are records going back centuries that talk about windless dry months when people starved to death because the mills had no power.
A small water mill, even one using a pelton wheel and modern generating plant would probably only power a modern house or two and at great expense. The expense part I know about as a friend of mine has a house with land in a perfect location but his ROI is in the decades even with tax breaks (he did the research).

anyhow, yes you are starting to answer my initial question, which is what does it take to get hydro working.
what size of river do you need for it?

These installations were abandoned largely because they were very seasonal and impossible to scale up compared to steam power; they could be used to generate electricity on a micro or pico scale but the capital cost is high, typically 5 times as much as small scale onshore wind. A few community schemes have been built in Scotland in the 50-200kW range but the government binning the FIT criteria brought any unstarted schemes to a halt. I was peripherally involved in a local one but it was still at the fagpacket stage when the plug was pulled, it would have been about 150kW with a capital cost of maybe £1m. The numbers can only be made to add up with FIT payments.maybe not as big as the hydro plants in scotland I have seen, but surely this is a perfect way of gaining energy.

What do you mean by long term?Dave
In 50-100 years time.
