Solar powering more than a sixth of the UK right now?

I don't write much about energy any more, but thought it would be interesting to put up this graph showing the impact that solar is having on UK electricity demand. Basically it shows how much lower demand for electricity from the grid was yesterday (Tues 30 June) compared to a similar Tuesday in July two years ago.

I reckon this is from solar.

But why would it show up as a reduction? Well, the grid is made up of two main bits, the national 'high speed' grid and a local grid. Decentralised solar reduces the demand on the main 'high speed' grid, which these numbers show.




The gap between the two lines is the difference in consumption. A little bit of this is falling use of electricity (about 1GW), part of a general trend, but as the day goes on it gets wider and wider, reaching about 4.6 GW... given there are something like 3-4GW of rooftop solar in the UK this fits perfectly!

In fact given that total demand (including the 3-4GW of solar we are assuming) is around 40GW, this means that rooftop and decentralised solar alone may be doing nearly 10% of the UK's electricity. Add in the 2.5-3GW of large solar that feeds into the grid and we could be looking at more than 15% of national electricity!!!

Okay, that's just for a few hours on a very hot sunny day, but it is an indication of how much things are changing, and given that it has happened in just a couple of years, surely a sign of hope!

It's official - the beavers are back, and now I'm nervous

Devon's beavers - the ones that escaped and started to breed - have been returned to the wild. They have been tested for disease and are now back in the water. This is great news.

Amid all the congratulations and celebrations we must not forget that this was not supposed to happen. The government and the Angling Trust wanted rid of them. Their return is a triumph of campaigning, not of process.

Lots of groups were involved. The Devon Wildlife Trust and the local landowners deserve great credit for finding a practical solution, and managing the return. Friends of the Earth deserve recognition too, for helping to turn it into a national story, exposing the lies about disease risks and filing a legal action against the government to stop their removal when it looked most likely.

So I am thrilled, but also apprehensive. The return of these beavers must be just the start. We need to radically alter our relationship with nature. Good news stories like this are amazing, but they are also the exception. Species are in precipitous decline, and many of our habitats have never been in worse condition. We need to change tack, prioritizing wilder lands, removing unnecessary infrastructure and building denser, greener, 'biophillic' towns and cities. We must also redouble our efforts to return native species.

And this is where the Devon example makes me nervous. As the focus moves from the campaign to the implementation, we are once again hearing that this is an expensive business. Costs are high, and money is tight. But costs are only so high because we make it so. The Devon beavers are being released in an intensive scientific trial because that is the only way it is allowed. Let's not forget that they were there already.

Farmers and landowners too are agitating to be paid more in compensation or management fees to allow native wildlife to live on their lands. I can see the logic, but it is all wrong. Most of the time, all animals need to survive is the right habitat and to be left alone. Around the country other groups interested in returning beavers, or other species, will be watching and wondering if they can shoulder the costs.

At the same time there is a risk that this 'trial' will be used to out other reintroductions on ice. That people will say that now is not the time to talk about more.

But we must. There are so many species we need to bring back or reinforce in various parts of the country - wildcat, pine marten, lynx, wolf, golden eagle, sea eagle, wild boar. The point is not just that these are wonderful animals, but that they will help out existing wildlife too. Pine martens help red squirrels. Wild boar create wallows that benefit amphibians. Lynx control deer and aid forest regeneration. Wild cats control rabbits. It goes on and on.

And these animals must not just be returned, but allowed to be wild. We must learn to accept them and make space for them and if necessary manage them. They should become the fabric of our every day lives - wild creatures that can fill our myths and imaginations - not biological curiosities forever tagged and monitored and confined to tiny areas.

But I am getting ahead of myself. Whatever happens next, this is a great day, and great step forward.

Imagine if we could turn a city's derelicts into jungles?

TheMushyPea is currently residing in Bristol. It's a wonderful city, bursting with sustainable innovations, beautiful buildings, great bars and an alarming amount of patchwork clothing. It is also filled with a large number of derelict buildings. Old warehouses, abandoned 50s office blocks, yards and car parks. You name it, Bristol's got it.

There are strong positives to this state of affairs. It provides opportunities. It means opening a gallery or exhibition space is possible. It gives the potential for new housing and work areas within the city. Green cities must also be dense cities after all - otherwise we gobble up greenbelt and force people into their cars.

Having said all that there are a lot of pretty ugly urban catastrophes around. Some have been this way for decades, and might remain so for decades more. Furthermore many of the redevelopment plans, while perhaps an improvement, are hardly inspiring.

Imagine buildings like this coated in luscious greenery,
their forecourts a riot of wildlife. 
I think we could do better. Imagine if we could start to take just a few of the big hulking eyesores that dot the city, just a fraction of the most egregious concrete canyons, and 'rewild' them. We could coat the exteriors in green walls of native species, put in bat boxes and holes for birds. Shrubs and climbers could explode in the abandoned foyers and parking spots. Squirrels and polecats would battle through empty offices. It would be radical, and incredibly beautiful. It would be acknowledged around the world.

And it would be relatively cheap. There might need to be a few compulsory purchase orders, but in the scheme of urban renewal I would wager it would be a steal.

At a time when we know we need to bridge the disconnect between nature and urban living, what better way to show that Bristol is prepared to really do things differently.

Some sort of tropical overgrown building. Ours won't have these plants, but they'll still be beautiful.

London's got a new tree

Just behind Kings Cross, in the middle of a huge sea of construction, is a special tree. Around it is a bench, so you can sit and stare at it. It looks old, and venerable. Yet it is not some remnant preserved from before the development. Those have long since been removed. This is a new tree, a 63-year old swamp oak imported from Germany. Britain cannot even grow its own plants anymore.

Behind this woody museum stretches a short row of plane trees. They drop straight into the tarmac and concrete, kept alive by some underground network of drains. Around them steel and glass soar upwards. There are no birds but pigeons. It is amazing anything can survive at all. I would die in a matter of days if Pret a Manger could not keep me supplied.

Re-wilding has become the conservation issue of the day. The idea of reintroducing species, of releasing large areas of land to the forces of nature, of letting our own hearts wander is inspiring, enervating. But there is one area where I think the debate needs to progress more rapidly, and that is in rewilding our towns and cities. Yes we need the reforestation, but we must also begin to break down the barriers that surround the places where most of us live, and make wildlife an everyday event.

Old cities are not too bad at this. They are thick with stone and trees, riddled with old lanes and gardens. They provide green holes and quiet spaces. Newer cities are dreadful. They are neat and polished and smooth. The ground is sealed from the soil. They are ringed by roadways more effective than medieval fortifications – ditch, wall, death trap, wall.

The huge new developments I pass through in London and Bristol seem okay as far as shops and offices go, but they are a colossal missed opportunity for wildlife. Hedges and trees by Regent’s canal have been grubbed up and replaced with neat grass and pointless shrubs. The animals have gone. Not one of the new buildings that I can see has a garden, or even a green wall. There are no parks. The few plants, like the museum tree, are ornaments.

We must do better. We must make our cities conducive to life, make them ‘biophilic’.

Suburbs and garden cities will not do. Almost nothing is more destructive to the environment, wildlife and human interaction as a satellite town built around the motorcar. They have helped lead us to where we are. Dull lives. Sink estates with no economic activity, isolation and road-kill. At the same time our population keeps on growing. If we build on the greenbelt now, where will the next lot of houses go? No – the cities of the future must be dense and urban, but a new kind of urban which welcomes wildlife.

Lots of things will need to change to make this happen. Planning laws and buildings regulations for a start. Perhaps most of all though we will need to change what we think a city is for, and rethink ourselves. Yet I am convinced it will be worth it. By changing our cities, by insisting that new developments are built with wildlife in mind, it might even help our society. I would bet any money that a host of problems, mental and physical, could be eased with a little more beauty and wildness in our lives.

In the face of the infrastructure bill, Paddington wouldn't have a chance.



A lot of people are asking how Paddington Bear would be accepted by the UK's immigration system. I see what they are getting at, but there is one big problem. Paddington is a bear. As such he doesn't get to immigrate, and is governed by a whole different set of bureaucracy.

First of all, Paddington appears to be a spectacled bear (Tremarctos ornatus) from Peru, or at least some sort of being which shares a common ancestor with that animal. He may be able to walk and wear raincoats, but a bear is still a bear in wildlife law. Furthermore he a member of an endangered species listed on CITES Appendix I. That makes it illegal to transport or possess him without a license. I suspect that the Brown family have no such permission.

Okay, purists may quibble that CITES didn't exist in 1958 when the original books came out, but as far as the remake goes, they're in trouble, as are the airlines and boats which took him to Britain.

Of course CITES is often not enforced (that's why there is still a huge illegal wildlife trade) and does not apply to species which spread themselves naturally. So might he sneak in? The trouble is at some point he will be seen, and come to the attention of the authorities. The question then will be - is Paddington's arrival in Britain merely the result of changes in the species natural range?

Currently natural range is poorly defined, but the new infrastructure bill going through Parliament would see it fall somewhere into two categories - the historic range of a species, and a species which arrives by itself naturally, with no human help.

The wild boar which live in the UK are in their former natural range (they were once found right across Britain until a few hundred years ago), but because the government judges them to be here by unnatural means (they likely escaped from breeding centres), they are not considered to be native. The chances of a bear from South America which arrived by boat and train, carrying a suitcase and being fed sandwiches being judged to be within its natural range are slim at best.

Sadly, it seems likely that as a non-native and potentially invasive species, Paddington would be more likely to have a 'species control order' placed on him. At best he would be trapped and placed in the zoo, at worst hired marksmen would be able to force their way into the Brown property and shoot him.

The truth is that our government takes such a narrow view of wildlife that even native species which have lived in this country for decades, which bring many benefits and which form an essential and historical part of our natural fauna, have a hard time being left alone. A bear from Peru wouldn't have a chance.

Camden, Islington - sort it out!!!

Parochial blog today. York Way is looking its usual disgusting self. No big surprise this, and at least there were no big piles of dumped rubbish today, but still, the fact that this is just normal background to my daily walk is not good. Please - Camden, Islington - sort it out. Camden take the West side, Islington the East. London is getting dirtier and dirtier all the time, to the point that people no longer expect large parts of it to be clean, and stop caring.

If you need money, fine some people chucking litter. You have the powers. You could make thousands in a day just wandering around the borough. Or fine the Nightclub up the road. And provide some bins.

The Boar Wars - how the infrastructure bill is specifically targeting wild boar.

Moving away from beavers for a while to one of my other favourite animals - the wild boar. As you know there are wild populations living and breeding in several parts of Britain, escapees who have become established and are doing well. Like the beaver they are a native animal doing what they do best - boosting biodiversity and bringing a little life back to the forest.

So far the government has left the management of these animals up to local authorities and landowners, and while there are lots of problems in how we are dealing with our new neighbours (no proper population estimates or official recognition for starters), there is not at present a policy of eradication, and this is to DEFRA's credit. So it is with great concern that I have been watching the amendments to the Infrastructure Bill that is making its way through the commons.

This Bill contains provisions, weirdly, for removing endangered species. Back in July George Monbiot flagged up the general negative impact these could have on reintroductions, in that they could lead to any animal not currently listed as living in Britain being classed as non-native. I am still hopeful that this general issue can be over come, but I am also dismayed at the obvious targeting of wild boar.

The point is that the infrastructure bill allows for Species Control Orders on invasive species, and potentially those which are not ordinarily resident. These orders make it legal for the government to force its way  onto someones land to kill a species

In recent amendments tabled to the Bill by the government (stay with me) they proposed creating a class of animals called 'not normally present'. This included some criteria, and a list. There was just one animal on the list - the wild boar. Despite the fact that they are native, and that they have been living and breeding in Britain for over 20 years, they want to make sure that they are not officially 'here'. It is biological bureaucracy of the oddest kind. There can only be one reason for this - they want the option of going after them.

Of course there is no guarantee this will be the final language, and I suppose its inclusion could just be a precaution. Perhaps the government has no intention of trying to wipe out boar populations, but in playing its hand so obviously, we get a useful insight into DEFRAs thinking.

NOTE:

The amendment says:

“PART IB
ANIMALS NO LONGER NORMALLY PRESENT

  
Common name

Scientific name

Boar, Wild

Sus Scrofa.””
