The Paris agreement on climate change has been ratified, earlier than most people expected. Some believes that means the issue is on its way to being resolved. That is absolutely not the case.

Donald Trump’s election as president is a major setback because it removes any sense of American leadership on the issue. But that is not the only cause for concern. The inconvenient truth is that the use of coal in growing emerging economies continues to outpace anything being achieved elsewhere. The global energy market is changing; oil demand is coming to a peak and renewables are getting cheaper. But that, however important, is as yet having no more than a minor effect on the climate issue. We have to be realistic and prepare accordingly. Read more

A changing of the guard in an organisation is a good time at which to pause and reconsider every aspect of strategy. The mistakes of the past can be admitted, entrenched but outdated positions can be quietly left behind and altered circumstances accepted. That is what should happen now in the UK in relation to energy policy. Read more

Energy demand in China appears to have decoupled from GDP

The changes taking place in the world energy market are not just a matter of oversupply or the unwillingness of Saudi Arabia to rein in production. Demand has stagnated and in some areas is falling. The fall is unexpected — all the standard projections still cheerfully predict ever rising demand driven by population growth and the spread of prosperity in emerging economies. That assumption, however, begins to look too simplistic. The reality is more complex and, for producers, much more challenging. Forget the old debate about peak oil. Now it seems we are approaching peak energy. Read more

With a few honourable exceptions, the debate on British membership of the EU has so far consisted of a contest between the outs and the half outs – that is, those who want Britain to leave completely and those prepared to stay only if the country is protected from further incursion by immigrants or European policy makers. The other approach – active engagement to change and improve what happens – has barely been articulated. In several areas positive engagement is much needed and offers substantial benefits. Energy policy is a good place to start.

The EU has only limited competence when it comes to energy policy. The mix of fuels and the tax system under which they are traded remain matters of national choice. That isn’t likely to change. It would be a waste of time to try to force France to accept fracking or to tell the Germans that they are going to have to keep nuclear power. Any attempt to centralise such emotive decisions will fail. Read more

Is climate change the cause of extreme weather events? Until now the link has been suspected but never confirmed with scientific confidence. That position is now changing. A new study from the US confirms that for some extreme events there is a causal connection.

This link between climate science and immediate weather conditions can only strengthen the case of those arguing for policy change. The impact of a damaging heatwave in terms of deaths, sickness and other social and economic costs is much more likely to rouse public opinion than the distant prospect of what might to some sound like a modest increase in the global mean temperature. All politics are local, and they are also immediate. The discount rate applied to future possibilities is very high: what could happen to a future generation decades matters much less than what is happening to me here and now. It brings climate to the foreground and diminishes the argument of those who say that since we don’t know everything we should do nothing and wait until we see how things turn out. If the impact is immediate and people are dying as a result, the call for action will be loud.

One of the most dangerous illusions in the debate around the implications of climate change is the notion that the impact will only be material when the carbon concentration in the atmosphere exceeds some defined limit — usually quoted as 450ppm. At that point global mean temperatures will rise by an average of 2 degrees centigrade and the problems will begin. I do appreciate that the science is much more complicated but I think this is how the challenge is seen by many non-expert policy makers and politicians.

That view is mistaken. It implies an accuracy in the knowledge of the relationship between carbon concentration and the effect on temperatures that doesn’t yet exist — not least because, as Martin Rees, the former President of the Royal Society puts it, we are conducting an experiment with the earth’s atmosphere which has never been tried before. We don’t know with any degree of certainty that 450ppm will produce an average rise of 2 degrees and we don’t know what the variations around that average figure might be across the world. The case for action is driven by the precautionary principle. But there is another known unknown and that is the extent and nature of the impact in the shorter term — before we get to 450ppm.

Two papers published in the last few weeks provide a sobering reality check after the rhetorical success of the Paris climate change conference in December. Getting any agreement was a diplomatic triumph but producing real change on the scale necessary will be much more difficult. The two documents are very different but both excellent pieces of work. Their calculations and assumptions are detailed, transparent and, most important of all, evidence based. Both, however, reflect a degree of unjustified optimism. Read more

FRANCE-POLITICS-GOVERNMENT

The most interesting comment at Davos this year came from the French economy minister Emmanuel Macron who said that he simply did not believe for a second the figures put out by the Chinese government claiming that their economy had grown by 6.9 per cent in 2015. To anyone familiar with Chinese statistics the comment is welcome because it brings into sharp focus the fact that no one can trust the data being produced by what is now one of the world’s largest economies. The doubts are not limited to macro economic numbers. Chinese data on the energy sector also deserve to be regarded with great scepticism.

There are three reasons why Chinese data might be inaccurate. The first is that it is simply extremely hard to gather reliable data across a country which is so vast. Good data is hard to come by. In Nigeria gross domestic product was revised upwards in 2013 by 89 per cent because the old basis of calculation was inaccurate. There are many issues even in much smaller and more developed countries. Read more

The agreement on climate change in Paris will satisfy no one. The complaints are predictable and have already begun.

The commitments made are not legally binding and political decisions could be altered by future elections or regime changes. The funds available for adjustment are too limited and, of course, there is no carbon price.

All true, but politics is the art of the possible and what has been agreed is a triumph for French diplomacy and for the French Foreign Minister Laurent Fabius personally. Many deserve credit but success depends on leadership. He is the Energy Personality of the Year because he has played a crucial role in changing how the sector will evolve worldwide for decades to come. Read more

Storage — whether of grain or of knowledge through the printed word — has been a crucial element in human development. Of all the many technical advances that are transforming the energy business none is potentially more important than storage: it give us the ability to control the way, and crucially the timing, of energy consumption. Used on a major scale it could help to make heat and light available to those outside the commercial economy and could radically alter the energy mix.

Two excellent recent research reports summarise the current state of the art in the field and offer some predictions. The first is from Lazards and is the latest in a series assessing trends in the costs of different mechanisms. The second is from Moody’s and concentrates on the advances being made in reducing the cost of batteries.

In discussing storage it is important to demolish two myths. First, the technological advances are not about to transform the energy system to the point where a major proportion of consumers defect from existing distribution systems. Second, it does not require a dramatic breakthrough for making it on a significant scale to become economic. Read more

The potential impact of climate change is beginning to get serious attention beyond specialist climate scientists. Last week at the Ecole Militaire in Paris — the elite college for the French defence forces — military and civilian leaders debated the risks and the defence and security implications at a seminar organised jointly by the French Senate and the defence ministry. Three ministers, including those of foreign affairs and defence, led the debate.

Many of the risks are well known — such as the possibility of desertification in particular regions, of water shortages leading to inadequate harvests and a lack of food supplies and on the other hand the prospect of floods or sudden surges in temperature; and the risk of diseases and epidemics spread by dirty water. The problems are concentrated in areas such as Africa, where climate change will compound existing problems such as inadequate healthcare, poverty and weak governments. Read more

VATICAN-POPE-AUDIENCE

The shocking thing about the papal encyclical Laudate Si is not that it was leaked in advance nor even that it embraces the idea that most emissions of greenhouse gases are the result of human activity. The thing that should shock readers is its attack on science and technology — the very tools, indeed the only tools, which offer a solution to climate change.

I am not a student of theology and therefore do not claim to understand the subtleties of the Catholic Church’s teaching on science. But since the Pope has moved outside his own natural territory and into energy policy, some response seems appropriate.

From a distance, Pope Francis seems to embody decency. He is modest, frugal, concerned for the poor and hostile to the creepier side of the church hierarchy in Rome and beyond. That makes him stand out in a world of shallow and cynical “leaders”. He commands millions of followers and his words deserve to be taken seriously whether one is a Catholic or not. Read more

Carbon capture and storage is one of the key elements in the various plans for keeping total emissions within safe limits. Different projections give slightly different numbers but the broad consensus is that the process of sequestration — taking the carbon out of hydrocarbons before they are burnt and then burying it — should account for between a sixth and a fifth of the net reduction needed by 2050 if we are to keep global warming to 2C or less. If CCS doesn’t happen on the scale required, either the level of emissions and the risks of climate change will be higher or some other solution must be found. Sir David King, the former UK government chief scientist, puts it more dramatically: “CCS is the only hope for mankind

Keeping global warming to 2C means that the amount of CO2 captured and stored must rise steadily to well over 7,000 Mt per annum by the year 2050. Is CCS on this scale likely to happen? As Simon Evans and Rosamund Pearce point out in an excellent article for Carbon Brief, the industrial scale of the operation required to capture and store that amount of CO2 is far greater than the scale of the current international oil industry. Looking objectively at the current state of play the answer must be that it is very, very unlikely. Why? And what can do done about it? Read more

British Government Signs A Deal For New Nuclear Power Plant

The election is over and against all expectations we have a clear result. When it comes to energy policy, however, the agenda will be set not by what the Conservative party has promised in its manifesto but by external events. A number of looming issues are already obvious and the government will have no control over most of them.

The first is the further postponement of the plans for nuclear development starting at Hinkley Point in Somerset. Two new reactors capable of supplying some 7 per cent of total UK electricity demand are planned. The first was originally supposed to be on stream in time to cook Christmas dinner in 2017. But despite the prospect of a lavish price — index linked for 35 years regardless of what happens to global energy prices – and £10bn of even more generous financial guarantees, funding for the investment required is not in place. The reluctance of investors to commit will not be helped by the technical problems in the reactor vessels, which are now under investigation by the French nuclear regulator. This problem has widespread implications for the companies involved (Areva and EDF) and for nuclear development in many countries across the world, starting with France itself. Read more

Downturn In Oil Prices Rattles Texas Oil Economy

Almost all the major oil and gas companies I know are undertaking substantial reviews of their policies on climate change. That is true in Europe and in the US. Why now, and what will be the outcome ?

First, it is important to stress that the rethinking is not being driven by the recent attacks on the companies. Describing Shell and its chief executive Ben van Beurden as “narcissistic, paranoid and psychopathic” is just childish and reduces what should be a serious debate to playground abuse. The reviews began before the latest media campaigns and are driven by corporate strategic concerns. Read more

CHINA-ENVIRONMENT-CLIMATE

The signals are clear – but contradictary. China has embraced the concept of climate change and is allowing officials to discuss the risks openly. Two weeks ago Zheng Guogang, head of the Chinese metereological administration warned of droughts, rainstorms and the threat to major infrastructure projects. He could not have spoken without permission.

But at the same time economic growth remains the prime objective of Chinese policy and growth requires the consumption of ever greater volumes of primary energy, led by coal.

Demand may have slipped by a small amount last year but new coal plants are still being opened. Coal consumption in China has doubled in the last ten years. China is now the world’s largest economy and consumes more than half of all the coal used worldwide each year. Within two decades, even on quite modest assumptions about economic growth it will have an economy twice the size of the US with personal living standards equivalent to those of the US in 1980. But it will still be an economy powered by coal – with demand on current policies up by another 20 to 25 per cent according to the forecasts produced by the International Energy AgencyRead more

I have never given much credence to the idea that an international agreement on climate change capable of establishing a global carbon price was likely to be reached – either in Paris this December or anywhere else – anytime soon.

If Europe, which is way ahead of the rest of the world when it comes to climate policy, can’t set its own carbon price, what hope is there that the US, India and all the others will?

As a result I’ve never taken seriously the view that a vast amount of energy investment by the oil and gas companies will be left stranded as carbon-generating fuels are priced out of the market. The argument has always felt like wishful thinking. If everyone obeyed the Ten Commandments there would be no prisons and the police forces of the world would be redundant.

But, and it is a very important qualification, change doesn’t come just through legislation and international treaties. Technology is arguably much more important and there is growing evidence that some fundamental changes are coming that will over time put a question mark over investments in the old energy systems. Read more

Forget Opec. If cartels can’t control output, they can’t control prices and in due course they fall apart, usually with a great deal of ill will in the process. The evidence of the last six months is that Opec can’t control the market — ask yourself how many Opec members want to see a price of $60 a barrel for their oil. Some in Saudi Arabia think a low price can squeeze out competing suppliers, but that feels like a justification after the fact of a fall which they can’t control. The question now is how the process of adjustment to the new price level will work. Read more

Given the seriousness of the messages contained in last week’s report from the International Panel on Climate Change, one might expect some sense of urgency around the search for solutions. Regrettably, that is not the case. Governments and campaigners especially in Europe seem rigidly focused on pursuing the holy grail of a global deal, under which the world’s major economies would move together in a synchronised process of decarbonisation. The futility of that approach is evidenced by the fact that Europe itself has been unable to set an effective carbon price and has done almost nothing to advance the technology of carbon capture and storage (CCS), which is one of the few ways in which emissions could be managed. Read more
