The moon moves the tides twice a day. We are missing out on this power.
The UK has some of the highest tides in the world. Tidal power using barrages can have problems with sedimentation but inlet-outlet design can substantially solve this . Wild life changes but does not lose out. We loose out by not doing it. On every count, it is better than nuclear.

Good news for those who have been eyeing Tesla’s new Solar Roof – the company just announced pricing for its photovoltaic tiles, and they come in at just $21.85 per square foot. That, they claim is nearly 20 percent cheaper than a normal roof once you factor in the energy savings and tax credits. Well, almost there – do it without tax credits and then we are there but OK for tax credits to get started.
At least, someone has finally grasped that making a conventional tiled roof, and then retro-fitting solar panels is little short of insane suicide. We have the technology to make a roof out of solar panels and we should never, from this day on, ever make another conventional roof.

The national debt (what successive government have borrowed to buy our votes) is now £1.8 trillion. The interest, we heard on the BBC News this evening (4th Oct 18) is greater than the entire education budget. That is insane. The people we borrow off (Chinese, Arab countries, etc) ) will not kill us off completely, they will almost do that but not quite, just milk us forever. That is the nature of debt. We need to balance the books. The only thing big enough is shale gas. Stop importing energy when we are sitting on a vast reservoir. by the way, we can do it safely.
Today, 24th December, the book “Survival” can be downloaded free. Today, you can read, for free, a chapter on shale gas which is a balanced view of what was known at the time, and that things have not changed much. No doubt, today or shortly, there will be howls of anger and disagreement from the anti’s in the groups who purport to stand up for the “environment” and some will post rude comments on Amazon and wherever. Well, they are entitles to deny the facts and be generally bigoted. The truth is that, in isolation, they are partly right; shale gas, if we had the option, would be best left in the ground and we would use “renewable” fuels. Unfortunately, that is only part of the truth. The Earth is already grossly over-populated and people need food and energy. The UN says that around 10 million (yes, 100,000,000) people in central Africa are on the edge of starving to death. (Not a nice way to die.) Food production takes energy. Electric cars need electricity. We need these things now, not at some time a few decades down the line. Shale gas is a transition fuel with a clean burn. We need to bridge the gap. We need it to close the national debt before we become another Greece.. We need the jobs. We need to use shale to re-build an economy which currently is superficially still OK but is actually sliding downwards quite quickly. We need to use shale gas as a step in generating a genuinely sustainable economy and environment. We need to all pull in the same direction to do that. Would that we had leadership that could create that vision and lead us into it.
Batteries are changing the way we will employ renewable energy sources.
The problem with solar and wind turbines is that they are never 24-7. To make matters worse, the human race tends to use a lot more power first thing in the morning and in early evening (at “peak”) than the rest of the day. Now we have the technology to produce batteries to take in power from the grid at off peak times and feed it back in during the peak demand – economically.
For farmers, as a rough guide, 1 acre = 30MW and typically sites will be 10-49 MW sites. As a very rough guide, 1 MW of battery would earn £2000 pa, index linked, for 20 years. So, if you have from half to one and half acres (allowing for access), give me an e-mail on email@example.com
The USAF cemetry at Maddingly, Cambridge UK. What kind of world are we handing on to our children?
Globally, we are on the edge of a renewable energy revolution. It is not that we did not have the technology, what is different is that the technology, bit by bit, is becoming economic. This bodes well for the human race. However, there is a problem in that much of the economically attractive solutions, especially solar panels, need land. There is a problem with land – they have stopped making it. So we need to use alternatives including never making a roof out of tiles or inactive sheet and, instead, making it of solar panels. We need the land to produce food, fibres and timber – but in a different way. Instead of using mineral Nitrogen which costs at least 21,000 kWh per tonne of N to deliver, we need to feed those crops on urban wastes. It has been done and can be scaled up safely. https://www.amazon.co.uk/dp/B01H63EQX0/ref=dp-kindle-redirect?_encoding=UTF8&btkr=1
