Coal Collapses: Renewables Rise

UK electricity 1920 – 2020

Coal is collapsing. The above graph shows how coal use grew up until the 1980’s, then slowly and erratically declined until about 2012, and then plummeted over the last eight years. In 2019 it made up less than 2% of UK electricity supply: in 2020 it will be less than that, and soon it will dwindle to nothing. As of today, 13th May 2020, the UK has gone for 33 days without using any coal to generate electricity, for the first time since the 1880’s. Countries across Europe are permanently shutting down their last coal fired power stations. Belgium was the first to do so, in 2016, followed last month by Austria, then days later, Sweden. Over the next few years many countries, including UK, will permanently shut their last coal fired power stations.

A few years ago there was a lot of nonsense talked about Peak Oil and how demand would outstrip supply causing energy prices to skyrocket. Energy prices have been falling for years, and this process is made more acute by the Covid 19 pandemic further suppressing demand. Oil prices actually went negative recently, for the first time ever, with people being paid to take it from the overflowing oil field facilities.

As the above graph shows UK electricity demand has been falling for nearly two decades, as is the case in many mature economies. Low prices, coupled with the disinvestment campaign, have made it increasingly hard for coal companies to expand, even in Australia which historically had a very profitable coal sector. Most fossil fuel extraction is now unprofitable.

Renewables are on the rise. Prices are falling and performance is improving. Storage and interconnection technologies are making it ever cheaper and easier to rely on renewables for all our electricity needs. As heating and transportation systems are electrified electricity demand will rise, but this rise can be dealt with in a 100% renewables scenario.

As countries emerge from the Covid 19 pandemic they will need to make choices about the kind of future they want. Old coal, oil and other obsolete sectors of the economy will be lobbying for bailouts. We can have clean air, better health, less road accidents, more social justice and a whole raft of other benefits by opting for a Green New Deal. At the heart of any Green New Deal is the switch from fossil fuels to renewables. Of course we need huge other changes to create a more socially just and less polluting future, but let’s celebrate the progress that has been made. One indicator is our individual carbon emissions stemming from electricity use. In UK these have fallen from 2.6 tonnes per person in 2010 to below one tonne in 2019. This is very good news and has been due to the decline in coal, made possible by falling demand and the rise of renewables.

Climate: Action Required

Mark Carney, governor of the Bank of England, has said that capital markets are financing projects likely to fuel a catastrophic rise in global heating. This of course is exactly why Extinction Rebellion activists have been rebelling in the city of London this week. Carney also pointed out that companies with assets concentrated in the fossil fuel sector are likely to go bankrupt, just as others in the cleantech sector flourish.

The scale and speed of the energy transition required to avert catastrophe is way beyond what any politicians are advocating. Let’s take the energy debate in Australia where they currently generate about 20% of their electricity from renewables, and which the governing party energy minister thinks is too much, and is advocating for huge investments in coal. The opposition parties are advocating increasing renewables by 2030, the Labor party to 50% and the Green Party to 100%. Alan Finkel, Australia’s chief scientist, is calling for a goal of 700%, which to me seems a sensible way forward. Cheap wind and solar could easily meet all Australia’s electricity needs, and facilitate the energy transition in the transport and built environment sectors, and open up a huge new market in the form of clean energy exports. Already plans are afoot to lay an undersea cable to Singapore to directly export renewable electricity and for a huge growth in green hydrogen for export to Japan, Korea and China, helping them rapidly decarbonise. These are the sort of economic changes to which Mark Carney was referring. The question is where are the politicians needed to implement such profound and rapid changes?

Meanwhile Prince William is in Pakistan and has called for climate action after seeing for himself glacial retreat and consequent flooding and drought problems. He has called for greater cooperation between the UK and Pakistan on the issue. Pakistan, like Australia, has enormous solar potential. The Institute for Energy Economics and Financial Analysis has published a detailed paper on ‘Pakistan’s Power Future’, where they point out that solar and wind are already the cheapest forms of new energy and are projected to only get cheaper. Currently solar provides only 0.5% and wind 1.5% of Pakistan’s electricity. Pakistan currently generates 61% of its electricity from largely imported and expensive oil and gas. It would be good for Pakistan’s balance of payments, for local communities currently struggling without electricity, and for the global climate if their politicians worked with the many people who could help them rapidly develop their renewable energy potential.

Here in UK Boris Johnson has just announced that he will chair a new government committee on climate change. It is right that the Prime Minister chairs such a committee, but hard to imagine anyone less qualified to do the job. If I was to chair the committee I’d want to invite Professor Peter Strachan from Robert Gordon University in Aberdeen and Jeremy Leggett from Solarcentury as my key advisors. Sadly Boris is unlikely to listen to such voices and unlikely to take any sensible action to avert climatic, ecological and financial collapse, which is why Extinction Rebellion, Fridays for Future, Greenpeace and others will keep up their protests for urgent and radical change.

Muddle… or Decisive Action?

Students lobbying Councilors to declare a Climate Emergency

Students lobbying Councilors to declare a Climate Emergency

Last Friday Herefordshire Council unanimously declared a Climate Emergency. It was an inspiring day. About a hundred of us old environmental activists were outside the Shirehall when along came about one hundred and seventy young students who had marched chanting from the collages, down Aylestone Hill and through High Town. Our councillors had seldom, if ever, seen so much support for a motion to be passed. Yesterday the same council approved their own Transport Package, which essentially commits them to spending vast sums of money on road building and peanuts for walking, cycling and public transport. This, of course, is exactly the kind of policy that shows they are not serious about the Climate Emergency that they themselves had declared just a few days earlier. It reflects the muddled thinking of governments around the World, who continue to give billions in subsidies to keep the old fossil fuel industries going, while at the same time professing to be concerned about climate change, ecological breakdown and appalling air quality. It is why more and more people are taking to the streets globally, with groups like Extinction Rebellion and School Strike for Climate Action, demanding immediate and decisive action.

This coming Friday, 15th March, there will be a global school strike for climate action. As of this morning 1209 actions in 92 countries have been announced, and many more are being added each day. I follow many of the organisers on Twitter, and these young people, some only ten years old, are so powerful and eloquent speakers. They put most of our elected politicians to shame.

We need to make policy and investment decisions fit to the physical realities of the ecological crisis. Take road building. While our local council’s top priority seems to be to build ever more roads George Monbiot suggests a target of reducing car use by 90% over the next decade. Halting the manufacture, sale and use of fossil fuel cars, lorries and buses is a political decision. As I have repeatedly argued on this blog battery electric and hydrogen fuel cell alternatives already exist, and having most of the cars in car sharing clubs rather than private ownership we can further decrease the damage they do and the space they take up. If we are serious about action on climate change, or children’s health, or the liveability of our cities, then we have to make planning policy decisions in the understanding that the era of the privately owned motor car is over.
