"Seems the last couple of days sunshine and offshore strong winds picked our Renewables above or close to a new record at 65% but media are obviously distracted to notice it." It doesn't get reported because it's not a real story. Yes, wind and solar output peaked at nearly 65%, but it soon fell back to about 30%. Peak gas usage yesterday was 40%, which is very low, but it will go back to its normal 60% when the weather changes. And the weather always does change. When green energy sources can cover 66% of demand over an entire day, that's when it's worth celebrating. | |||

"And at 12:45. Of 27.7 GW consumption 29% Renewables 61% Gas - 3.5% Coal Good while it lasted!!" Yea it could be 100% all the time with a mix of nuclear wind and solar maybe some tidle thrown in as well

Sadly, tidal is never going to provide any useful level of power. | |||

"Sadly, tidal is never going to provide any useful level of power." "Tidal is one of the most Powerful and reliable natural sources of energy around the UK. The entire sea moves almost twice a day. " That's absolutely true. It's an incredibly powerful force, ripping turbines from their moorings, scouring out the foundations from under-sea installations, and snapping in half the wave power devices left out in bad weather. There are some limited cases where tidal power could be usefully harnessed, but not that many. The marine environment is incredibly hostile, and it will always be cheaper and simpler to put up land-based systems instead. | |||

Currently, the Nuclear part of the mix is almost constantly 17%-19%, I have not looked at the size of the UK Nuclear fleet, but only multiplied 5 times would kill off Gas consumption almost completely. Just the cost per kwh and the waste legacy.. | |||

Problem is thers always soemone saying that it will take too long. Everything is taking too long because the powers that be spend so much time just talking about it

Everything is taking too long because the powers that be spend so much time just talking about it" The problem isn't that it takes a long time to build a nuclear power station, the problem is that is nigh on impossible to agree a site for one. As soon as a potential site is announced, a massive protest group gets set up to try to stop it. All sorts of legal action is initiated to tie up the process, and the financiers pull out because of the uncertainty. What we need is a change in the law to allow the government to get the damn things built whether the locals like it or not. | |||

"And Tuesday night at 23:40. UK is consuming 28GW electricity, 6% renewable and 72% from Gas. Winter is a stones throw away. Storage heaters, Heat Pumps, EV charging, lighting and industry, then Gas boilers. At the beginning of Autumn over 70% of our electricity is from an at risk source." A bit of beat but seems gas is a green energy now according to the EU | |||

You can call it narrow-minded, or you can call or realism. The idea of tidal has been around for just as long as wind power. If you look around today you see wind power systems everywhere you look, making a genuinely useful contribution to our energy mix. But how many tidal systems are there in full time operation? There are 8 in the entire world, with only 2 of them making any useful contribution, and both of those making less than half what a gas power station does. Is that narrow-minded thinking holding it back? Or is it just that is too difficult and too expensive for too little return? | |||

As for the marine environment being too harsh, I guess nobody told Norway that. | |||

"More like no genuine government or private investment into funding development." And why is that? There's been plenty of funding poured into wind and solar, so why is everyone staying away from tidal? Is it because they haven't solved the basic problems yet? "As for moorings, this is basic engineering, just like floating or planted turbines." It is basic engineering. It's done every day to install off-shore wind turbines. But those are installed in slack water areas where there's less movement of water, to make the installation and maintenance easier. Tidal turbines would have to be in high water movement areas to be useful, and that's a lot harder to do. Haven't we all recently seen pictures of buildings and bridges being washed away when a river gets high? Lots of water moving at speed is incredibly difficult to resist. And you can't just block it off for a couple of months to allow the work crew to prepare the area before installation. "They talk about storage, there is plenty of unused capacity in Pumped Storage to store energy during days the tides are out of sync." The only pumped storage power station that the UK has is Dinorwig. Whilst it is a wonderful feat of engineering, it has a storage of slightly over 9 GWh, with a maximum output of a bit over 1.7GW, meaning that it can supply enough power to run about 5% of the UK, for 6 hours. If we had another 39 of them, we'd be able to cover the whole country for the period between the tides, but they don't yet exist. "It is feasible and possible and there are numerous places it could be installed if there was the will." Dinosaur shows that it is feasible, and possible, but there just aren't many places where we could built more. You need a mountain of a certain shape, and we just don't have them. Those that are suitable are mostly in Scotland, where investors fear the impact of nationalism. The SNP also wouldn't want to see UK government funds being put into infrastructure that would make it harder to separate. | |||

"I always thought that wood pellets from cut down trees, transported halfway around the world on diesel burning ships were classed as "renewable"" Definitely not. Renewable energy is defined as: Energy from a source that is not depleted when used, such as wind or solar power. | |||

It takes minutes to burn a tree but bloody years to grow one. Don’t sound very sustainable to me  | |||

They do count as renewable, for the reasons you state. In fact that's the only actually renewable energy source we have, since solar and wind aren't being 'renewed' in any way. It's a stupid name for those things. What was wrong with 'green energy sources'? | |||

"It has been for a while, especially when it's 'Green Washed' into Hydrogen. I cannot get my head around that one. Cleaner than Coal, kg for kg Greener than Coal but certainly not Green. I just hope people have listened and got a gas heater and couple of Butane bottles set aside. Although 50% cheaper for business today, no mention of severe reduction in consumption as they are in France and Germany. Looks like the UK is going for broke in "cutting down the last tree". At least, if there is no supply, running up the bill isn't a worry." As I understand it the EU has classed gas as a green energy no matter how it is used. It has upset several green groups who are to take them to court over it. | |||

""Europe will count natural gas and nuclear as green energy in some circumstances", is the quote." The words 'some circumstances' mean 'if there isn't enough renewable energy', and this definition is used to qualify sustainable investment grants. There's hardly likely to be sufficient renewables if fossil fuels are allowed to swallow up the grant money is there. | |||

"Pumped Storage: there's more than one. The Loch Lomond one nearly capsized my powerboat. Sat quietly having lunch when valves opened lifting boat 3 foot and pulling it into a vortex many years ago." That doesn't sound fun. But Loch Lomond is normal hydro-electric, there's no pumped storage. | |||

Order up some new nuclear power plants, figure out how to store energy generated during the day. Get china and indias pollution issues under control as well as gavin newsomes forestry management in california that puts so many tons of pollution in the air that contributes so drastically to climate change in california. Little bit of regulation on our energy markets would be helpful to take away all the payouts that benefit a few people but so drastically affects so many. | |||
