England Could Produce 13 Times More Renewable Energy, Using Less Than 3% of Land (theguardian.com) 222
England could produce 13 times more renewable energy than it does now, while using less than 3% of its land, analysis has found. The Guardian: Onshore wind and solar projects could provide enough electricity to power all the households in England two and a half times over, the research by Exeter University, commissioned by Friends of the Earth (FoE), suggested. Currently, about 17 terawatt hours of electricity a year comes from homegrown renewables on land. But there is potential for 130TWh to come from solar panels, and 96TWh from onshore wind. These figures are reached by only taking into account the most suitable sites, excluding national parks, areas of outstanding natural beauty, higher grade agricultural land and heritage sites.
Some commentators have argued that solar farms will reduce the UK's ability to grow its own food, but the new analysis suggests there is plenty of land that can be used without impairing agricultural production. More land is now taken up by golf courses than solar farms, and developers can be required to enhance biodiversity through simple measures such as maintaining hedgerows and ponds. Onshore windfarms were in effect banned in 2015 by the then prime minister, David Cameron. Rishi Sunak last year claimed to make moves towards lifting the ban, through small changes to the planning regulations, but campaigners say they were ineffectual and real planning reform is needed. No plans were submitted for new windfarms in England last year, and few new developments are coming forward, despite high gas prices, rising bills and onshore wind being the cheapest form of electricity generation.

UK plans a fleet of small modular nuclear reactors to meet their energy needs.
https://www.msn.com/en-us/mone... [msn.com]
The fine article is an admission of concerns on land use from renewable energy in the UK. This is not a new concern as Dr David MacKay pointed out the problems of wind and solar power meeting the energy needs for UK years ago in his book and website. http://www.withouthotair.com/ [withouthotair.com]
Dr. MacKay spoke on what UK needed to do for low CO2 energy for much of his life, making it a point to not state any conclusions but rather just point to the options and let the audience decide. In the last interview before his death Dr. MacKay deviated from this tactic and stated UK would need nuclear fission as a part of its energy mix or it will fail to meet future energy needs.
Much ado has been made over rising costs and construction delays for new nuclear power in UK, but both become irrelevant if there's no better option offered. If Friends of the Earth are to live up to their name then they need to do more than express enthusiasm on how UK could grow their renewable energy supply quickly, they must also face the realities of a cold dunkelflaute which can put the nation into a very dangerous and expensive energy shortage. Dr. MacKay's study may be a few years old by now but it is still based on some fundamental realities that exist. Friends of the Earth must know that UK cannot operate on renewable energy alone if they did their study correctly. Thankfully we see reality being recognized by policy makers in the UK, and elsewhere around the world, with investment in nuclear power. We will still need renewable energy but we can't rely on renewable energy alone. Every nation that got to a point of technological and economic development to allow building nuclear power plants have found it difficult to do without. In the USA we've had decades of nuclear fission providing something like 20% of our electricity and with each closing of a nuclear power plant there's increased use of fossil fuels to replace them. This isn't because people hate clean air and a stable climate but because renewable energy cannot reliably provide energy when and where it is needed.
To those that believe the solution to the problem of renewable energy being intermittent is energy storage then that shows a lack of understanding the problem. Uranium and thorium is stored energy, stores of energy upon which we can draw from as desired. These are energy stores that will not take up nearly as much valuable land, materials, and other resources as renewable energy and whatever else people have in mind as energy stores. It's great to read on how UK could put up many more affordable onshore windmills, and I'd believe Dr. MacKay would even agree, but that still doesn't eliminate the need for nuclear power in the UK.

The concept of "base load" is relevant for a grid based on nuclear and fossil fuels. Nuclear or fossil provides some power all the time, while smaller and faster gas turbines are used for peaks, plus some pumped hydro.
Battery technology has already had a significant impact on peakers -- it is many times faster. As a grid moves toward renewables, I think, the idea of "base load" will fall away. There will energy generation on one hand, and storage/import/export to cope with peaks. Solving intermittency of su

We've been over this before with you. You do not understand what base load is.
Solar can not produce at night. Wind is unpredictable. Therefore neither is useful for base load. Repeating the lie does not make it so.
I have a huge solar setup on my house and the largest battery farm you can reasonably buy for a residential system. I get zero power and night and the giant ass expensive as fuck batteries do not last all night. Recharging them the next day while still powering my home requires drawing from the grid. I love my zero electric bill but this is not an off the grid base load option.
For kicks, I looked up how much power I could get from a full moon. It won't light a tiny bulb for a few seconds. Solar is not base load capable.
This is likely due to the 1%'ers trying to keep us on their evil grid to control us and keep us enslaved.

Really? How large are we talking?
I have 30 kWh on my house, and that easily lasts all night. Even while cooling the house in summer.
In winter I don't get much power from the solar panels, but for about 2/3 of the year my roof can charge the batteries while running the house. I live near Seattle... I'll bet people in California and Texas really could run their homes year-round from solar.
In short, my personal experience disproves you

30 kWh eh?
Well a quick cursory google and I find powervault p4 which can provide up to 24 kWh for, and I quote "large homes and businesses".
Now, assuming most of the UK population dont live on business premises, how many large homes do we have?
Not many.
How many can afford such a system... very few.
Most UK households are terraced and cant always fir a heat pump legally. 30kWh of battery capacity is something that rich people will have, with big houses. Bosses, CEO's etc.

Wind is extremely predictable, especially in the short term. The UK National Grid actually has less standby generation for wind than it does for nuclear and fossil fuels, because a turbine going down takes a few megawatts off the grid, compared to a reactor going down taking gigawatts off without warning.
On the timescales that the grid needs to bring alternative sources online, e.g. 15 minutes, wind is extremely predictable and reliable. Plus, wind farms often have batteries to smooth output over very short

> And yet other people run their homes of batteries for multiple days.
Thats BS. Unless you just use a 11W bulb.
Each day my house uses 3-4kWh. That will empty a battery system in a day.
It's even more fun when we think about batteries on the grid, should we have those, everywhere, no matter the huge cost and supply issues, a battery backed UK grid will run the UK's grid demands for... less than a day.

I think wind has hit 100% coverage in the UK at points of some days in the last few years. Itself a big achievement, but that's not base load ability by a long stretch

> Wind and solar have been fine for base load for over a decade now
Impossible.
Variable sources can never be "base load". If that were the case then wind and solar would be base load at night during an anti-cyclone were, if you dont know, you have no wind for a week or so.
Only nuclear, oil, gas, biomas and interconnectors can be base load.
