Hooray! Alexandria Ocasio-Cortez!

Alexandria Ocasio-Cortez

Alexandria Ocasio-Cortez: rising star and climate radical

The American midterm elections are over and what they reveal is something very similar to what is happening in Europe; the rather flabby, corporate centre ground is collapsing and voters are moving out to the extremes. In Europe, where most countries have at least half a dozen parties in their national parliaments these trends are reflected as the emergence of some parties and the contraction of others, whereas in USA the trends take place within the Republican and Democrat parties. In a blog a couple of weeks ago I looked at the growth of Green parties in elections in Belgium, Luxembourg and the German state of Bavaria. Since then the German state of Hesse has had elections that reinforced this message, as again the traditional mainstream parties lost ground to both the far right AfD and to the Green party.

The best analysis of the midterms that I have read has been Paul Mason, and he is very good at identifying the demographic groupings that are driving the Trump phenomenon and its antidote, a much more socially caring and ecologically literate movement of more urban, educated, cosmopolitan and racially diverse people. Within the Democratic Party they form a democratic socialist grouping. For years Bernie Sanders was just about the only person representing this more radical perspective. Paul Mason identifies many of the emerging people and ideas within this movement. I want to focus on just one person. If Trump embodies all that is bad, then, for me, Alexandria Ocasio-Cortez embodies all that is good.

In a Tweet the meteorologist and commentator Eric Holthaus described Alexandria Ocasio-Cortez as “the only American politician I’ve ever seen with a climate change plan that is in line with intergenerational justice.” She also has some refreshingly radical ideas on inequality, gun crime and much else that is so dysfunctional about American society.

Action on climate change in America has been lead from academia by people like Mark Z Jacobson, through the courts by Our Children’s Trust and though grassroots campaigns by the likes of 350.org. Now at last these people have someone within the House of Representatives who really is focused on the same kind of actions that they are demanding. Millions of us around the World are delighted to see someone like Alexander Ocasio-Cortez emerging as a true leader, and I for one would love to see her become President of USA. As she is only twenty-nine years old she has time ahead of her, but why not as the presidential candidate in 2020? Who better?

Extinction Rebellion

Greta Thunberg

Greta Thunberg at today’s Extinction Rebellion rally in Parliament Square

Humanity faces a challenge of existential proportions. Our destructive global civilization is causing myriad forms of pollution. Everywhere the air, water and soils are becoming degraded; the climate is breaking down, the oceans acidifying, habitats are being obliterated and countless species are in terminal decline. Countless reports over many decades have only added to the scientific evidence. Small steps to combat the destruction have always been offset by greater damage elsewhere in the system.

From childhood this has been the bedrock of my motivation in life. I gave my first talk on all this in 1972 to my school sixth form. I’ve spent decades struggling to understand what to do to ‘save the world’. (Of course, the world will carry on, it is humanity which needs saving) I’ve been a very small voice, like millions of others, generally ignored and marginalized by the mainstream.

The mainstream political culture that dominated the planet for the entire post war era did at least pay lip service to sustainability, human rights and the welfare of the poor. That mainstream seems now to be crumbling. Voters in many countries are moving to the extremes.

Trump in USA, Putin in Russia, Durente in the Philippines and now Bolsonaro in Brazil, these four men seem to embody the emergent far right. They seem to delight in the destruction of our living world and care not a jot about the welfare of the poor. In the UK the conservatives seem to be moving from the old mainstream centre into the territory of the far right, as evidenced by this week’s budget, the whole Brexit process and their move from the EPP to the ECR groupings within the European Parliament.

Recent elections in the German states of Hesse and Bavaria typified the global situation, with votes for the mainstream conservatives and labour parties collapsing and a worrying rise in votes for the far right Alternative for Deutschland. On the positive side the Green vote also rose dramatically.

Generally, in most counties, Greens are the only political party who seem to understand the true magnitude of the impending ecological crisis and the scale of changes needed to avert the worst. The window of time humanity has is narrow: recent reports from the IPPC suggest we only have about twelve years to transform the entire global economy.

Today the Extinction Rebellion was launched in Parliament Square. This is a new movement promoting taking non-violent direct action on climate change and all the other aspects of the global ecological crisis. Many of the politicians and writers whom I most admire are there today, including Molly Scott Cato, Caroline Lucas and George Monbiot. Also speaking was the inspirational fifteen year old Swedish climate activist Greta Thunberg. (On her Twitter account she has a two minute video clip pinned at the top… do please watch it)

Various accounts of today’s launch of Extinction Rebellion are worth reading: try Rupert Read, Molly Scott Cato, Chloe Farand and Jeremy Williams, and see the Extinction Rebellion website. I couldn’t be there in person today. I wish them well and hope millions join their global call to action.

Humanity’s future lies in the balance. The choice is stark: the inaction and muddle of the old political mainstream, the doubling down on destruction of the far right or the hopeful idealism and radical practical action demanded by Green parties, myriad environmental groups, and now, Extinction Rebellion.

California opts for Renewables

Kevin de Leon

Kevin de Leon, California Senate Leader and proposer of the 100% RE legislation

Yesterday California passed legislation to achieve 100% low carbon electricity by 2045, with 60% by 2030. This is a policy academics such as Mark Z Jacobson and many environmentalists have long advocated. The legislation was introduced by the Democratic Senate Leader Kevin de Leon and was passed with the support of climate conscious republicans such as Chad Mayes and Arnold Schwarzenegger.

Meanwhile a few weeks ago Donald Trump scrapped Obama’s clean power plan and is attempting to promote greater use of coal. If successful this would of course be a disaster for public health and for the climate. However industry analysts think his legislation will have only marginal effects on keeping a few coal plants operating a bit longer, in a few States.

A huge division is opening up in America as a growing number of States, led by California, Hawaii and Vermont are pursuing 100% renewable electricity. Environmental considerations rightly play a part in their thinking, but so too does the falling costs of wind and solar power. Also renewables create many more jobs than coal, gas or nuclear. Trump makes much of trying to protect jobs in the coal industry, but his real motivation seems to be more about protecting the share price of his backers in the coal industry, and I think also his personal hatred of anything that smacks of care for the planet.

California has abundant renewable resources. By developing these resources intelligently it could create many social, economic and environmental benefits. It might well find it has got to 100% renewable electricity well before the 2045 deadline it has set itself.

India: Coal or Solar?

India has built a lot of coal power stations, but will they become stranded assets, displaced by cheaper, cleaner solar?

India has built a lot of coal power stations, but will they become stranded assets, displaced by cheaper, cleaner solar?

Last month atmospheric Co2 levels passed 410 parts per million. To avert climatic catastrophe humanity needs to shift away from fossil fuels as quickly as possible. India presents us with both the scale of the challenge and the scope of possibility. The government of India wants to bring electricity to all its 1.3 billion people, the population is still rising and the country is rapidly industrializing. Energy demand is increasing, and so too carbon emissions. Many new coal fired power stations were built in the decade 2007 to 2017, more than doubling coal capacity. This all bodes ill for local air quality, and for the global climate. At the Paris climate summit a couple of years back the Indian government was rather dragging its feet, only promising to decrease the carbon intensity of its economy, while planning for rapid economic growth and emissions still rising for years to come.

However things could change for the better very rapidly. The price of solar, both photovoltaic and concentrating solar thermal, is falling fast, and India has a very good solar resource. In 2017 for the first time India added more new renewable capacity than new coal. Many coal plants are proving economically unviable: they simply cannot match solar on price and are shutting down. As solar prices are predicted to keep falling this should only accelerate this process. Currently the government are still trying to protect coal from these market forces. They are also beginning to grasp the new opportunities that solar can bring. For isolated rural communities across India local solar plus storage will be key to their development. At the other extreme are new solar based megacities.

The Dholera Special Investment Region, located near the head of the Gulf of Khambhat in the Indian state of Gujarat, is a huge area earmarked for a new city and cleantech industrial hub. A 5 GW solar pv plant is planned, with local manufacture of solar cells and panels and other ancillary industries. This will further decrease the price of solar electricity, hastening the demise of coal. A project like Dholera opens up many new opportunities to create new forms of prosperity not based on ever more pollution but on new and ecologically sustainable technologies. It would be a perfect place to invest heavily in solar desalination and new forms of super productive hydroponic agriculture, on many forms of energy storage and on electric and hydrogen fuel cell transportation systems. India could lead the world with the speed to its energy transition. Technologically India has lagged behind Europe, USA or China, but it has probably the best solar resource of these four. It could leapfrog them, and be the first solar powered superpower. Essentially it is a political choice, which path India will follow, coal based or solar based development? The economics of going all out for solar are looking increasingly good, which is good news for India, and for the rest of us.

Towards an Ecological Civilization

Paris

Can we make our cities, and World, less polluted and better to live in? This picture is of Paris, one of the places leading the way.

Humanity wants a better future. Increasingly we are united in our demands for a cleaner, less polluted environment, and we see this as a fundamental human right. We want to protect the oceans, the forests and the air we breathe from the multiple onslaughts of industrial civilization. Achieving a peaceful, prosperous and sustainable lifestyle for all humanity is a goal worth striving for.  Increasingly we have the technological tools to help us do this, and there is a global groundswell providing the pressure politicians need to enact positive change.

Slowly the United Nations is moving towards recognising the human right to a healthy environment. Over the last eight and a quarter years I’ve posted three hundred blogs highlighting some of the positive steps that are being taken on this path to a better future. My focus has been on the shift from a fossil fuel economy to one based on renewables. This change in energy use is one part of a bigger shift, what David Korten and Joanna Macy refer to as ‘The Great Turning’, from Imperial Civilization to Ecological Civilization.

In a great video Jeremy Leggett argues that the transition away from fossil fuels and to a 100% renewables based global economy is happening faster than most people understand. He identifies three meta-narratives in this process. First, the global groundswell of people, governments and increasingly also from corporations who see the need for change. Second, the falling costs and increasing efficiency of the renewable energy technologies, and thirdly, a whole set of problems within the old energy incumbency, from the ponzi like debt structure of the fracking industry to the inability of everything from coal and oil to nuclear to compete with renewables on either cost or environmental legislation. Together all these trends conspire towards an exponentially fast energy transition. We will see a lot of stranded assets.

There are many victories to celebrate. Over the last few years UK carbon emissions have fallen, so that in 2017 they dropped to levels last seen in 1890. This rapid improvement was mainly due to the decline in coal and rise of renewable sources of electricity.

As I’ve stressed in a number of recent blogs, the next big change needs to be in transport. At last many cities are starting to ban cars and make city centre areas radically more pedestrian focused. Cycle paths and public transport infrastructure are being improved. Several German cities are about to introduce free public transport in order to help get people to quit their car addiction. Many cities are banning the most polluting vehicles, and as I’ve shown in recent blogs very much cleaner alternatives are rapidly developing. Over the next decade I would predict air quality to improve and carbon emissions from transport to fall. Putin, Trump and few ghastly politicians will do all they can to stop this transition, but the overwhelming tide of global opinion combined with the pace of technological innovation is stacked against them.

Renewables Rampant

UK elec

Coal Collapses and Renewables Rise. This graph of UK electricity; part of a global trend.

At this time each year on this blog I like to highlight something that has helped in the process to make a more ecologically sustainable, socially just and peaceful future possible. Sometimes I focus on a political leader who has made an outstanding contribution, sometimes on a particular innovative clean energy technology. This year I want to celebrate a whole global trend, the switch from fossil fuels to renewables, and especially the growth of North Sea wind.

Ever since I started blogging I’ve been saying humanity should switch to 100% renewables, for electricity, heating, cooling and transport. We can then simultaneously ditch fossil fuels and nuclear. The speed with which renewable technologies are progressing is staggering. Performance is improving while costs keep tumbling. The ecological case for moving from ‘The Fossil Fuel Age’ to ‘The Solar Age’ always was strong, now it is the most economically sensible thing to do.

In 2017 the first contract has been signed which will see an offshore wind farm built without subsidies. The German electrical utility EnBW submitted a bid of Euro 0.00 in a competitive tendering process to build the 900 MW He Dreiht windfarm in the North Sea. As solar and wind energy get cheaper the case for greater international grid integration gets stronger. The Dutch grid operator TenneT has proposed building an artificial island on the Dogger Bank and linking all the electrical grids of the countries surrounding the North Sea together in a hub and spoke arrangement. Electricity could then be sent to wherever in Europe it was needed. I’ve blogged before about this, but now support seems to growing and it is projected to be in operation by about 2027. TenneT estimates that 30GW of windfarms might connect to the first hub, and that other hubs might also be built. This would be a huge step forward in reducing carbon emissions and pollution in general across much of Europe.

All over the world innumerable renewable energy projects are demonstrating that we can provide electricity, heating, cooling and transport to all 7.6 billion of us while tackling climate change and achieving all the other global goals. Over the coming year I’ll highlight more of the technologies and politicians that are showing the path to a better future.

Bonn and Climate Leadership

Bonn conference

The Bonn Climate talks: where will the required leadership come from?

The Bonn Climate Change Conference has ended. Plenty of fine ambitious rhetoric but a failure to grasp the nettle and do what is necessary. Bill McKibben, writing in the New Yorker, is clear about the dilemma. Most politicians are caught in a bind, realising the need for action but constrained by a desire to protect old polluting industries. Angela Merkel has said “Climate change is an issue determining our destiny as mankind – it will determine the wellbeing of us”, yet she remains protective of the German coal and car industries. Canada’s Justin Trudeau and California’s Jerry Brown are similarly conflicted.

Although 500 NGO’s have signed The Lofoten Declaration no leading politicians have done so. Many politicians want to be seen to be leading in the world of cleantech and renewables, but are unable to grasp the concept of managed decline. Most of the known fossil fuel reserves need to be left in the ground, and the industries that depend on them need to be wound down. This needs to done in ways that are socially just. Green politicians like Caroline Lucas, Jesse Klaver, Isabella Lovin and Andrew Weaver understand this, but none of them are leading their nations. Many small and vulnerable countries such as Fiji are trying to offer leadership, so too the UN. People are looking for political leadership from the elected leaders of major economies who have the power and money to create the top down political momentum. Technologically and philosophically the opportunities are amazing, but political leadership has long been lacking. Where might it come from?

It is absolutely not coming from USA or UK. Trump is utterly isolated as the only leader to quit the Paris Agreement. Britain is caught up with the parochial fantasy of Brexit. Angela Merkel, Justin Trudeau and Jerry Brown would like to be seen to be leading but are too constrained and too timid. Manish Bapna and Lailai Li, writing on the World Resources Institute website sound a positive note about Xi Jinping and China. Frances Beinecke writing on the Natural Resources Defence Council website has encouraging things to say about India. Probably leadership will be a collaborative venture, and I think the person most likely to draw the key players together may be France’s Emmanuel Macron. He has vision and ambition, seems to be able to break with old patterns of doing things and to work with others to make progress. He may not want to move as radically as the science suggests or greens advocate, but he is in a position of power and does clearly have leadership skills. The test will be whether he can lead France’s managed decline in fossil fuels while ramping up the cleantech sector, and do it in ways that are socially just. If he can collaborate with the rest of the EU, and with India and China to make this the new global norm, then he will have achieved the kind of leadership the planet and it’s people so desperately need.

Meat

Can eating meat be ecologically sustainable?

Can eating meat be ecologically sustainable?

Meat is a complex and controversial issue. Can it be part of a diet that is ecologically sustainable and socially just? Arguments rage about this issue. One of the complexities is that meat is produced in very variable ways. The very best systems of pasture management can, it is argued, sequester more carbon into the soil than is necessary to offset the methane the cattle produce. They can also be part of restoring biodiverse habitats. In a blog in June I sang the praises of Will Harris of White Oak Pastures. However this represents the very apex of good meat production. The vast majority of meat production is very much less sustainable. Most animals raised for human consumption are fed on grain and soya that would be much more beneficially eaten directly by people. Even the best systems of meat production use a lot of space per unit of food produced. It would certainly be a good thing if humanity could massively reduce its meat consumption, say by 80 or 90%.

One of the common assumptions people writing about population and diets was that as people get richer they would eat more meat. Throughout the Twentieth Century this held true: not any more. Veganism is growing rapidly in many countries, and it seems especially so among the young and better educated. Also for many of us who are omnivores we are eating a lot more meals that are plant based, with a very much reduced intake of meat and dairy.

Globally levels of meat consumption vary a lot. Argentina and Uruguay top the table of per capita meat eating. India and China traditionally ate very much less but as people are getting wealthier they are eating more. Total global meat consumption is still rising but this may not go on much longer if veganism, vegetarianism and low meat lifestyles become more common, as I think they probably will.

If humanity could reduce its meat consumption dramatically, (say by 80%) that would free up an enormous area of land for other purposes. Some of this could be used for agroforestry or renewable energy projects, but the vast majority could be used for rewilding. Increasing the area of forests in the world could help restore habitats thus allowing biodiversity to flourish again, and it would be a very effective way of sequestering carbon, so vital in helping combat climate change.

Some people think that cultured meat, grown in laboratories, will replace traditional meat eating. Others see vegetable based meat substitutes, like textured soya protein as having a major role. Some argue we should switch from traditional meats to insects. Maybe meat eating will simply decline without the need for ersatz meats. Any of these perspectives may prove to be true. It is too early to say.

China gets serious about pollution

Air pollution in Beijing

Air pollution in Beijing

This week China has shut down about 40% of all its factories, approximately   80,000 of them. Some may be shut down permanently, some just until they can clean up their act. The early evidence is that fines are being strictly imposed as the tax bureau acts in tandem with the pollution inspectors. Some factory managers and owners may well be sent to jail. There will be disruption in global supply chains. The price of Chinese made things, from clothing to car components will increase a bit in the short term. A few percentage points may be knocked off Chinese GDP figures. However all these things seem a small price to pay for the benefits at stake.

China has a public health emergency in terms of local pollution. In rapidly reducing this local pollution many macro ecological threats from climate change to ocean acidification can also be mitigated. In a blog a couple of weeks ago I wrote about the need to create a pollution minimizing way of maximizing the social and economic benefits of a modern economy. By shutting down obsolete and dirty factories cleantech innovation will be stimulated, leading to more sustainable forms of prosperity. Just in purely economic terms China will probably benefit in the longer term.

Over the last sixty years or so successive legislation has helped clean up most of the rivers of Europe and North America. London’s air quality improved rapidly after the 1956 Clean Air Act. Cleaning up pollution always requires strong government leadership. This week Sadiq Khan introduced the new £10 toxicity charge for bringing older more polluting cars into the centre of London. Although this is to be welcomed, it is too little, too late. The pace of shifting to a cleantech economy needs to speed up dramatically.

The medical journal, The Lancet, estimates that 50,000 people in the UK, and 9 million globally, die each year due to poor air quality. It is time governments the world over took more radical steps to tackle pollution. It will mean shutting down thousands of businesses. This needs to be managed in ways that create greater social and economic security while cleaning up the mess. To me this seems quite doable. Stop subsidies to polluting industries, introduce hefty fines on all forms of pollution, introduce a universal basic income and incentivise cleantech innovation.

In numerous blogs I’ve sounded an optimistic note that China’s carbon emission might plummet over the coming decade. These factory closures will contribute to that goal, and they will also help ensure China is a leading economic powerhouse in the future. As USA under Trump and Britain under the quagmire of Brexit both look back to a fantasy of past glory China is forging ahead, creating the kind of economy which will typify the post fossil fuel age. China has a long way to go to reduce its horrendous pollution, but it is making a very bold start, and that is to be welcomed.

Time for Big Solar?

TuNur's proposal to build 4.5 GW of csp solar energy in Tunisia

TuNur’s proposal to build 4.5 GW of csp solar energy in Tunisia

The technology of concentrated solar power (csp) has been around for a long time. Augustin Mouchot pioneered its use in the 1860’s and Frank Shuman built an impressive system in Maadi, Egypt in 1912. I’ve long been a strong advocate. However prices remained high as rates of deployment were low, and rates of deployment were low because prices were high. This is now changing fast as several countries and companies compete to bring forward the technology. Over the last few years there have been significant price reductions of projects in Chile, Dubai, Morocco and elsewhere as the technology improves. In February I blogged about China starting work on 20 demonstration projects, and as they establish a supply chain of mass produced components prices will continue to fall. Concentrating solar power has the advantage over solar pv and wind in that energy storage is typically built into the projects so they can guarantee to supply electricity 24 hours a day. As techniques of thermal energy storage improve the advantages of concentrating solar continue to improve. Some very big schemes are currently under construction or have been announced.

At Ouarzazate in Morocco a 580 MW plant is being built in four stages, the first of which is already in operation. In Dubai they are planning a 5 GW mix of solar pv and csp. In 2014 I blogged about TuNur’s proposal to build a system in Tunisia which recently took a step forward as they applied for a permit to build a 4.5 GW plant over three stages, the first exporting electricity to Malta, the next to Italy and the third to France. A couple of weeks ago the Northwest Electric Power Design Institute proposed to build a vast 7.4GW CSP facility in Akesai County, in China’s remote Xinjiang region.

The Paris Climate Agreement incorporated the ambitious goal of keeping global warming to less than 1.5 degrees Centigrade. In many ways governments are failing to implement the policies necessary to achieve this objective. Collectively we are failing to curb our wasteful and profligate lifestyles. However there is one area where the news is consistently very good and that is the speed with which renewable energy is progressing. As the costs of renewables continues to tumble coal, gas and nuclear are all failing to compete.

In UK the falling cost of offshore wind received a lot of media coverage, undermining the viability of the government’s commitment to Hinkley and further nuclear power projects. In India numerous coal projects are being abandoned as India embraces cheap solar pv. The falling cost of concentrating solar power has received less media coverage, but is of just as great significance. If these giant csp projects all go ahead they will displace a lot of fossil fuel usage which of course will be very good news from a climate change perspective. If they are done with the right social and economic policies in place they could also transform the lives of many people, especially in poorer countries like Tunisia.
