Why waste oil burning it when we can use it to make things?

The cost of <em>not</em> switching to renewables.

Grist's David Roberts highlights a really important piece of research by the World Future Council, examining the non-climate-change-related cost of not switching to renewables.

The reasoning is simple: fossil fuels can be burned to make energy, or used as a raw material (e.g. for production of plastics). Every barrel of oil we burn for energy is therefore a barrel which we can't use as a raw material. Thus:

Their burning — whenever they could have been replaced by renewables — is costly capital destruction.

The report concludes that the "future usage loss" resulting from current consumption is between $3.2trn and $3.4trn a year.

Roberts writes that "the exact numbers here are, like numbers in all economic modeling, probably going to turn out to be wrong," and he's definitely right. At first glance, the most important thing absent from the initial paper is no discussion of the difference between present and future value.

This isn't just the problem that resources worth $3.2trn at today's prices might not be worth that at tomorrow's; its also that rigorous economic analysis always discounts the future.

Consider it this way: if you had the option to be paid £100 now or £100 in a year, you would clearly choose the former. The money in the future is less valuable, even though it is nominally the same amount. That's partially because people want things now, of course; but it's also because if you took the £100 now and put it in a savings account, it would be worth more than £100 in 12 month's time. (And let's not even begin on the discussions of how new technology will change the value of fossil fuels as raw materials in ways we can't begin to predict. How will things change, for instance, if conductive plastics take off?)

The same thinking needs to be applied to the question of the "destruction" of potential resources. Their value today — and thus the degree to which they ought to encourage us to switch to renewables — is lower the further into the future we are going to use them.

But really, the discussion of the actual value is slightly moot. Unless we're doing a massive overview of the costs of climate change mitigation — a second Stern report — then we can't properly weigh those costs against all the others. What we can say is that this is an under-discussed benefit of switching to renewable technology sooner rather than later, and of promoting climate change prevention rather than mitigation.

Incidentally, the research also provides a counter-point to the claim that it's not safe to leave fossil fuels in the ground. That's the argument that:

If we build enough renewable energy capacity to supply our entire system, there are still fossil fuels ready to burn. The people who built the renewable capacity may not want to burn them – but what about the next government? Or the next generation?

One option is to prevent future irresponsibility by burning fossil fuels today but with carbon capture and storage, ensuring that the carbon goes back underground. But another option is to switch to renewables and then continue using the fossil fuels for material production, locking up carbon not in vaults underground but in plastics.

In that analysis, even landfills get an image rehabilitation. They become gigantic carbon sinks, encouraging further use of fossil fuels as raw materials, removing more and more potential atmospheric carbon from circulation. There's hope for everyone yet.

There's just one future for the left: Jeremy Corbyn

Labour's new leader is redefining Labour for the 21st century, argues Liam Young. 

The politics of the resurgent left comes down to one simple maxim: people are sick and tired of establishment politics. When one makes this statement it is usually met with some form of disapproval. But it is important to realise that there are two different types of people that you have this conversation with.

First there are the people I surround myself with in a professional environment: political types. Then there are the people I surround myself with socially: normal people.

Unsurprisingly the second category is larger than the first and it is also more important. We may sit on high horses on Twitter or Facebook and across a multitude of different media outlets saying what we think and how important what we think is, but in reality few outside of the bubble could care less.

People who support Jeremy Corbyn share articles that support Jeremy Corbyn - such as my own. People who want to discredit Jeremy Corbyn share articles that discredit Jeremy Corbyn - like none of my own. It is entirely unsurprising right? But outside of this bubble rests the future of the left. Normal people who talk about politics for perhaps five minutes a day are the people we need to be talking to, and I genuinely believe that Labour is starting to do just that.

People know that our economy is rigged and it is not just the "croissant eating London cosmopolitans" who know this. It is the self-employed tradesman who has zero protection should he have to take time off work if he becomes ill. It is the small business owner who sees multi-national corporations get away with paying a tiny fraction of the tax he or she has to pay. And yes, it is the single mother on benefits who is lambasted in the street without any consideration for the reasons she is in the position she is in. And it is the refugee being forced to work for less than the minimum wage by an exploitative employer who keeps them in line with the fear of deportation. 

The odds are stacked against all normal people, whether on a zero hours contract or working sixty hours a week. Labour has to make the argument from the left that is inclusive of all. It certainly isn’t an easy task. But we start by acknowledging the fact that most people do not want to talk left or right – most people do not even know what this actually means. Real people want to talk about values and principles: they want to see a vision for the future that works for them and their family. People do not want to talk about the politics that we have established today. They do not want personality politics, sharp suits or revelations on the front of newspapers. This may excite the bubble but people with busy lives outside of politics are thoroughly turned off by it. They want solid policy recommendations that they believe will make their lives better.

People have had enough of the same old, of the system working against them and then being told that it is within their interest to simply go along with it.  It is our human nature to seek to improve, to develop. At the last election Labour failed to offer a vision of future to the electorate and there was no blueprint that helped people to understand what they could achieve under a Labour government. In the states, Bernie Sanders is right to say that we need a political revolution. Here at home we've certainly had a small one of our own, embodying the disenchantment with our established political discourse. The same-old will win us nothing and that is why I am firmly behind Jeremy Corbyn’s vision of a new politics – the future of the left rests within it.
