Germany’s overdose of renewable energy

Anti-nuclear hysteria is destroying the environment

This is part 2 in a series. Click here to read part 1.

Germany now generates over 35% of its yearly electricity consumption from wind and solar sources. Over 30 000 wind turbines have been built, with a total installed capacity of nearly 60 GW. Germany now has approximately 1.7 million solar power (photovoltaic) installations, with an installed capacity of 46 GW. This looks very impressive.

Unfortunately, most of the time the actual amount of electricity produced is only a fraction of the installed capacity. Worse, on “bad days” it can fall to nearly zero. In 2016 for example there were 52 nights with essentially no wind blowing in the country. No Sun, no wind. Even taking “better days” into account, the average electricity output of wind and solar energy installations in Germany amounts to only about 17% of the installed capacity.

The obvious lesson is: if you want  a stable, secure electricity supply, then you will need reserve, or backup sources of electricity which can be activated on more or less short notice to fill the gaps between electricity demand and the fluctuating output from wind and solar sources.

The more wind and solar energy a nation decides to generate, the more backup capacity it will require. On “bad days” these backup sources must be able to supply up to 100% of the nation’s electricity demand. On “good days” (or during “good hours”) the backup sources will be used less, or even turned off, so that their capacity utilization will also be poor. Not very good economics.

Europe Leads The World In Environmental Protection

Europe Leads The World In Environmental Protection

Earlier this week, the European Union unveiled their European Investment Plan aimed at shifting 1 trillion euros into making the economy more environmentally friendly over the next 10 years.

Statista’s Willem Rpoer reports that the investment plan is in line with European Commission president Ursula von der Leyen’s Green Deal, which looks to make the European continent carbon-neutral by 2050. Since taking office, Von der Leyen has made climate change her top priority.

European countries have typically been leaders in the fight against climate change, with many ranking lowest in carbon emissions globally and highest in environmental quality. The newest trillion-euro investment plan looks to solidify Europe as the global example for combating global warming as other continents like Asia and North America continue to produce high carbon emissions and lag behind in renewable energy sources.

n 2019, Yale University released their Environmental Performance Index (EPI) for all 180 countries in order to gauge which countries had the highest environmental quality and which had the lowest.

THE RENEWABLE GREEN ENERGY MYTH: 50,000 Tons Of Non-Recyclable Wind Turbine Blades Dumped In The Landfill

THE RENEWABLE GREEN ENERGY MYTH: 50,000 Tons Of Non-Recyclable Wind Turbine Blades Dumped In The Landfill

Funny, no one seemed to consider what to do with the massive amount of wind turbine blades once they reached the end of their lifespan.  Thus, the irony of the present-day Green Energy Movement is the dumping of thousands of tons of “non-recyclable” supposedly renewable wind turbine blades in the country’s landfills.

Who would have thought? What’s even worse, is that the amount of wind turbine blades slated for waste disposal is forecasted to quadruple over the next fifteen years as a great deal more blades reach their 15-20 year lifespan.  Furthermore, the size and length of the newly installed wind turbine blades are now twice as large as they were 20-30 years ago.

Honestly, I hadn’t considered the tremendous amount of waste generated by the so-called “Renewable” wind power industry until a long-term reader sent me the link to the following article, Landfill begins burying non-recyclable Wind Turbine Blades:

Hundreds of giant windmill blades are being shipped to a landfill in Wyoming to be buried because they simply can’t be recycled.  Local media reports several wind farms in the state are sending over 900 un-reusable blades to the Casper Regional Landfill to be buried. While nearly 90 percent of old or decommissioned wind turbines, like the motor housing, can be refurbished or at least crushed, fiberglass windmill blades present a problem due to their size and strength.

“Our crushing equipment is not big enough to crush them,” a landfill representative told NPR.

Prior to burying the cumbersome, sometimes nearly 300-foot long blades, the landfill has to cut them up into smaller pieces onsite and stack them in order to save space during transportation.

Empty Gestures on Climate Change

Empty Gestures on Climate Change

When climate campaigners urge people to change their everyday behavior, they trivialize the challenge of global warming. The one individual action that citizens could take that would make a real difference would be to demand a vast increase in spending on green-energy research and development.

MALMÖ – Switch to energy-efficient light bulbs, wash your clothes in cold water, eat less meat, recycle more, and buy an electric car: we are being bombarded with instructions from climate campaigners, environmentalists, and the media about the everyday steps we all must take to tackle climate change. Unfortunately, these appeals trivialize the challenge of global warming, and divert our attention from the huge technological and policy changes that are needed to combat it.1

For example, the British nature-documentary presenter and environmental campaigner David Attenborough was once asked what he as an individual would do to fight climate change. He promised to unplug his phone charger when it was not in use.

Attenborough’s heart is no doubt in the right place. But even if he consistently unplugs his charger for a year, the resulting reduction in carbon-dioxide emissions will be equivalent to less than one-half of one-thousandth of the average person’s annual CO2 emissions in the United Kingdom. Moreover, charging accounts for less than 1% of a phone’s energy needs; the other 99% is required to manufacture the handset and operate data centers and cell towers. Almost everywhere, these processes are heavily reliant on fossil fuels.

Attenborough is far from alone in believing that small gestures can have a meaningful impact on the climate. In fact, even much larger-sounding commitments deliver only limited reductions in CO2 emissions. For example, environmental activists emphasize the need to give up eating meat and driving fossil-fuel-powered cars. But, although I am a vegetarian and do not own a car, I believe we need to be honest about what such choices can achieve.

It Bears Repeating: Renewables Alone Won’t End the Climate Crisis

It Bears Repeating: Renewables Alone Won’t End the Climate Crisis

‘We have to look at downsizing, degrowth, using less.’

WindTurbine.jpg
We’ve got a ways to go if we choose to reduce emissions by simply replacing fossil fuels with wind turbines. What also matters: using less energy.Photo via Shutterstock.

Although the media still portrays climate change as some vague threat to “the environment,” it is really a self-made blitzkrieg that is already destabilizing a highly energy-intensive and complex human civilization.

Greta Thunberg has spoken prophetically: our civilized house is on fire. 

But our collective politicians, blinded by ideology and technological illusions, refuse to panic, let alone call the community fire department. 

They behave as though they can just build another house somewhere else on Mars, and then watch the conflagration on Netflix

In that previous analysis, I quoted a Colorado professor, Roger Pielke Jr., who recently noted in Forbes that if we really wanted to reach zero carbon emissions by 2050, and we solely choose wind power as the solution, we’d need to build and deploy 1,500 wind turbines on about 300 square miles every day for the next 30 years.

We can’t do that, of course, because of physics and economics. Pielke was simply illustrating the scale of the challenge if we thought that renewables could do all the work for us.

But a great many readers questioned Pielke’s math; others questioned his motivation. Others questioned my sanity in quoting such a fellow.

Having written about energy for 30 years (and my best scribbling on the matter remains The Energy of Slaves), I thought Pielke’s numbers, which can vary with wind power due to location and size of blades, were largely accurate and conveyed the enormity of the task at hand, especially if we think our energy crisis is just a substitution problem.

‘A Breath of Fresh Air’: Offshore Wind Power Could Produce More Electricity Than World Uses

‘A Breath of Fresh Air’: Offshore Wind Power Could Produce More Electricity Than World Uses

“Let’s get going!”

A new report from the International Energy Agency released Friday claims that wind power could be a $1 trillion business by 2040 and that the power provided by the green technology has the potential to outstrip global energy needs. 

“Talk about a breath of fresh air,” tweeted writer Steven E. de Souza.

The IEA report looks at the business of wind power and opines that as investment increases and the technology becomes cheaper, the sector could explode. 

The IEA finds that global offshore wind capacity may increase 15-fold and attract around $1 trillion of cumulative investment by 2040. This is driven by falling costs, supportive government policies and some remarkable technological progress, such as larger turbines and floating foundations. That’s just the start—the IEA report finds that offshore wind technology has the potential to grow far more strongly with stepped-up support from policy makers.

“Offshore wind currently provides just 0.3% of global power generation, but its potential is vast,” said IEA executive director Fatih Birol.

It would take a major infrastructural commitment to develop wind power to the point that the renewable energy resource could take over the majority of global energy needs, but it’s not impossible. As The Guardian pointed out Friday, “if windfarms were built across all useable sites which are no further than 60km (37 miles) off the coast, and where coastal waters are no deeper than 60 metres, they could generate 36,000 terawatt hours of renewable electricity a year.”

“This would easily meeting the current global demand for electricity of 23,000 terawatt hours,” added The Guardian.

Green Party Debates Green New Deal

Green Party Debates Green New Deal

Despite the furor over the Green New Deal (GND), many of its supporters have no idea of the wide variety of views on it, especially within the Green Party (GP), where it originated in the US. From June through August, 2019 Missouri Greens held public discussions contrasting at least three distinct GP views to those from the Democratic Party (DP).

In June, the Green Party of St. Louis hosted a forum “The Green New Deal: Promise and Problems.” It led off with Ben Eisenberg of the Sunrise Movement describing his concerns with climate change and the extreme need for political groups to demand a switch to “100% clean, renewable energy” by 2030. Local Greens had coordinated an Extinction Rebellion protest at corporate Earth Day in April and realized the widespread appeal of the Alexandria Ocasio-Cortez AOC approach.

Henry Robertson of the Missouri Green Party followed, criticizing the popular DP perspective that climate problems require “a massive, urgent response.” He emphasized the destructiveness of economic growth and concluded “massive is not the cure for massiveness.” Robertson pointed out that “steel can’t be mass-produced without fossil fuels” and insisted that the Earth has hit its limits, meaning that production must be cut back.

Howie Hawkins, who spoke next, was the first to run for office on a GND platform as the 2010 New York Green Party candidate. He said that his original US program for a GND seeks 100% renewable energy by 2030 along with the right to single-payer healthcare, a guaranteed job at a living wage and affordable housing. It would create 20 million jobs and end destructive extraction.

A globalised solar-powered future is wholly unrealistic – and our economy is the reason why

A globalised solar-powered future is wholly unrealistic – and our economy is the reason why

Over the past two centuries, millions of dedicated people – revolutionaries, activists, politicians, and theorists – have been unable to curb the disastrous and increasingly globalised trajectory of economic polarisation and ecological degradation. This is perhaps because we are utterly trapped in flawed ways of thinking about technology and economy – as the current discourse on climate change shows.

Rising greenhouse gas emissions are not just generating climate change. They are giving more and more of us climate anxiety. Doomsday scenarios are capturing the headlines at an accelerating rate. Scientists from all over the world tell us that emissions in ten years must be half of what they were ten years ago, or we face apocalypse. School children like Greta Thunberg and activist movements like Extinction Rebellion are demanding that we panic. And rightly so. But what should we do to avoid disaster?

Most scientists, politicians, and business leaders tend to put their hope in technological progress. Regardless of ideology, there is a widespread expectation that new technologies will replace fossil fuels by harnessing renewable energy such as solar and wind. Many also trust that there will be technologies for removing carbon dioxide from the atmosphere and for “geoengineering” the Earth’s climate. The common denominator in these visions is the faith that we can save modern civilisation if we shift to new technologies. But “technology” is not a magic wand. It requires a lot of money, which means claims on labour and resources from other areas. We tend to forget this crucial fact.

I would argue that the way we take conventional “all-purpose” money for granted is the main reason why we have not understood how advanced technologies are dependent on the appropriation of labour and resources from elsewhere.

Solar Energy Is Renewable, But Is it Environmentally Just?

Solar Energy Is Renewable, But Is it Environmentally Just?

Story Transcript

DHARNA NOOR: It’s The Real News. I’m Dharna Noor.

The solar industry has been soaring over the past several years. The US is now home to some two million solar installations. Solar energy now provides about a fifth of California’s power and it makes sense that environmentalists champion the industry. Almost a third of the Earth’s greenhouse gas emissions come from the energy sector, so renewable energy sources like this are crucial.

But in a new book, our next guest shows that while “the net social and environmental benefits of solar are uncontested— more jobs, higher quality of life, and much less air pollution and greenhouse gas emissions— the industry supply chain still poses problems for specific communities, ecosystems and landscapes.”

So that’s what I’m here to unpack today with Dustin Mulvaney. He is an Associate Professor in the Environmental Studies Department at San Jose University and his new book that he’s here to talk about today is called Solar Power: Innovation, Sustainability, and Environmental Justice. Thanks so much for being here, Dustin.

DUSTIN MULVANEY: It’s a pleasure to join you. Thank you.

DHARNA NOOR: So, I want to start by talking to you about the conception of solar power. You maintain obviously in this book that solar power plays a really important role in fighting the climate crisis, but you also take a critical look at the political economy of solar. That’s something that’s often missing from environmental movements, because solar has what you call in the book a green halo. It’s sometimes exempt from critical examination. What do you hope that this book will achieve within that broader climate conversation?

What My Friends on the Left Need to Know About the Green New Deal

What My Friends on the Left Need to Know About the Green New Deal

“Nowhere has our public discourse failed us more egregiously than on the environment and climate change,” I wrote last year while reviewing the first sketches of a proposed Green New Deal. It’s since become a buzzword, but until now it remained only vaguely defined.

Now Senator and Democratic presidential candidate Bernie Sanders has significantly upped the ante. Sanders’ Green New Deal proposal is very specific, earmarking $16 trillion over 10 years to initiatives from “reaching 100 percent renewable energy for electricity and transportation by 2030” to reauthorizing the New Deal-era Civilian Conservation Corps to “coming together in a truly inclusive movement that prioritizes young people, workers, indigenous peoples, communities of color, and other historically marginalized groups.”

The opening to the Sanders campaign’s new page on the Green New Deal encapsulates the candidate’s view of the issue:

The climate crisis is not only the single greatest challenge facing our country; it is also our single greatest opportunity to build a more just and equitable future, but we must act immediately.

Sanders and I wouldn’t disagree that his plan represents a sea change in the way our government, society, and economy interact. The plan is gigantic. I want to fill page after page with factoids about how big it is, but just a few will suffice:

  • The proposal’s total cost is $16 trillion, over 20 times the cost of the New Deal (in today’s dollars, just under $700 billion).
  • If the proposal succeeded in creating 20 million jobs, it would raise the percentage of the workforce employed by the government to around a third, double what it is now.
  • Remember that goal of 100 percent renewables by 2030? We’re only at 15 percent now, meaning almost the entire U.S. energy system would be overhauled.

Is Global Warming an Existential Threat? Probably Not, But Still a Serious Issue.

Is Global Warming an Existential Threat? Probably Not, But Still a Serious Issue.

During the recent presidential debate, a number of candidates suggested that global warming represents an existential threat to mankind, and thus requires dramatic and immediate action.

Governor Jay Inslee has been particularly generous in the use of this term, but he is not alone.  Kamala Harris, Cory Booker, Bernie Sanders and Elizabeth Warren have said the same thing, as have several media outlets and environmental interest groups.

Some of these folks also claim that the window for action on climate change is closing–Jay Inslee suggests that the next president will be the last able to take effective steps.  Others suggest 10 or 12 years.

But are these existential threat claims true?  That is what we will examine in this blog.
An existential threat is one that threatens the very existence of mankind.    Something that is a simply a challenge or an inconvenience is not an existential threat. An existential threat must have the potential to undermine the very viability of human civilization.

As described below, global warming is a serious problem and its impacts will be substantial—but in no way does it seriously threaten our species or human civilization.  And with reasonable mitigation and adaptation,  mankind will continue to move forward—reducing poverty, living healthier lives, and stabilizing our population.

What do current climate models tell us?  These models are run under specific scenarios of emission of CO2 and other greenhouse gases (see figure).   In one, RCP8.5, we simply continue doing what we are doing, with escalating use of coal and oil.  Not much renewable energy.    Many believe this scenario is too pessimistic.  Much more reasonable is RCP 4.5, which has modestly increased emissions through 2040, declining after 2050.  I suspect this one will be closer to reality.

Going 100% renewable power means a lot of dirty mining

Going 100% renewable power means a lot of dirty mining

Preface. Everyone talks about oil spills, but what about the dirty mining that will have a huge polluting footprint on the earth, and potentially destroy the world’s largest sockeye salmon fishery among other side-effects? Renewables aren’t cleaner and greener than fossils, and require a hell of a lot of fossils to mine the ore, deliver it to a crusher, blast furnace, and fabrication, all accomplished with fossils. 

***

Sadasivam, N. 2019. Report: Going 100% renewable power means a lot of dirty mining. Grist.org

For more than a decade, indigenous communities in Alaska have been fighting to prevent the mining of copper and gold at Pebble Mine in Bristol Bay, home to the world’s largest sockeye salmon fishery and a crucial source of sustenance. The proposed mine, blocked under the Obama administration but inching forward under the Trump administration, has been billed by proponents as necessary to meet the growing demand for copper, which is used in wind turbines, batteries, and solar panels. Similar stories are playing out in Norway, where the Sámi community is fighting a copper mine, and in Papua New Guinea, where a company has been mining the seabed for gold and copper.

Weighing those trade-offs — between supporting mining in environmentally sensitive areas and sourcing metals needed to power renewables — is likely to become more common if countries continue generating more renewable energy. That’s according to a report out Wednesday from researchers at the Institute for Sustainable Futures at the University of Technology Sydney in Australia. The report, commissioned by the environmental organization Earthworks, finds that demand for metals such as copper, lithium and cobalt would skyrocket if countries around the world try to get their electric grids and transportation systems fully powered by renewable energy by 2050. Consequently, a rush to meet that demand could lead to more mining in countries with lax environmental and safety regulations and weak protections for workers.

Can Renewable Portfolio Standards make RE Work?

Can Renewable Portfolio Standards make RE Work?

Guest post by Geo who is a geologist working in Alaska

People want energy to be cleaner (i.e. emit less carbon dioxide). One way to do this is to use regulations to force either greater efficiency, or a switch to cleaner fuels.

A good example would be Corporate Average Fuel Economy (CAFE) standards in the United States. They were first enacted by the United States Congress in 1975, after the 1973–74 Arab Oil Embargo, to improve the average fuel economy of cars and light trucks (trucks, vans and sport utility vehicles) produced for sale in the United States. The idea was that slowly, across the board, the mileage of all cars and trucks produced in the U.S. would gradually increase. Over time this would result in cleaner air, and reduced oil usage. And perhaps save consumers money…

And it more or less worked as advertised. Standards were raised, and efficiency increased, largely without additional cost. U.S. cars are twice as fuel-efficient today as they were 40 years ago, saving car owners millions of dollars, and reducing air pollution. Arguably a win-win.

Figure 1: EPA “Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 through 2017,” EPA-420-S-18-001, January 2018.

A slight nuance was added in some markets. Certificates for high mileage vehicles could be traded, so that some manufacturers could continue producing low mileage vehicles. For example, under California’s Zero-Emission Vehicle (ZEV) Regulation and those of states that have adopted California’s standard, vehicle manufacturers are required to earn or purchase credits for compliance with their annual regulatory requirements. This means that a certain number of electric cars must be sold to balance any low mileage vehicles.

UK climate emergency is official policy

UK climate emergency is official policy

Heathrow’s expansion is now in question. Image: By J Patrick Fischer, via Wikimedia Commons

Major changes in the government’s policy on fossil fuels will be vital to tackling the UK climate emergency that Parliament has recognised.

LONDON, 3 May, 2019 − The United Kingdom has taken a potentially momentous policy decision: it says there is a UK climate emergency.

On 1 May British members of Parliament (MPs) became the world’s first national legislature to declare a formal climate and environment emergency, saying they hoped they could work with like-minded countries across the world to take action to avoid more than 1.5°C of global warming.

No-one yet knows what will be the practical result of the resolution proposed by Jeremy Corbyn, the Opposition Labour leader, but UK politicians were under pressure to act following a series of high-profile strikes by school students in recent months and demonstrations by a new climate protest organisation, Extinction Rebellion (XR),  whose supporters closed roads in the centre of London for a week.

The Conservative government ordered its MPs not to oppose the Labour resolution, and it was passed without a vote.

Zero carbon by 2050

Hours after the MPs’ decision, a long-awaited detailed report by the government’s official advisors, the Committee on Climate Change, was published. It recommends cutting the UK’s greenhouse gas emissions to net zero by 2050. The current target is 80%.

The report says the government should accept the new target immediately, pass it into law in the next few months and begin to implement policies to achieve it. The committee says that will mean the end of petrol and diesel cars on British roads, a cut in meat consumption, an end to gas boilers for heating buildings, planting 1.5 billion trees to store carbon, a vast increase in renewable energy, and many other measures.

Mainstream to jetstream

Mainstream to jetstream 

A couple of decades ago, renewable energy was almost an outlier: the new kid on the block. But now, solar and wind are not just mainstream: in both developed and emerging economies, they are the preferred option when it comes to power generation.

A powerful synergy of enabling factors and demand-side attributes is propelling solar and wind to compete against, and win, in competition with even the most cost-effective and flexible hydrocarbon-fuelled sources of power. Renewable energy is now the preferred choice when it comes  to reliable, affordable, and environmentally responsible energy.

A new report on global renewable energy trends from Deloitte Insights charts the astonishingly rapid disruption of traditional energy systems and markets that renewables are causing as the cost of photovoltaic and windfarm power plants continues to fall.  

Clearing the way

Longstanding barriers to the greater deployment of renewables have faded thanks to three strong attributes: rapidly approaching grid parity, cost-effective and reliable grid integration, and technological innovation. Solar and wind can now beat conventional sources on price while increasingly matching their performance. Moreover, the integration of renewables is actually solving grid problems rather than exacerbating them. Wind and solar are now competitive across global markets even without subsidies.

Onshore wind has become the world’s lowest-cost energy sources for power generation, with an unsubsidized levelized cost of US$ 30 -60/MWh, which falls below the range of the cheapest fossil fuel , natural gas—which weighs in at around US$ 42 – 78/MWh. Except for combined-cycle gas plants, the levelized costs of all conventional sources and nonintermittent renewables have either remained flat (biomass and coal) or increased (geothermal, hydropower, and nuclear) over the past eight years, while the cost of onshore wind and utility-scale photovoltaic (PV) plants have dropped by 67 and 86 percent respectively as the cost of components has plummeted and efficiency has increased—trends that are expected to continue.
