Mining For Green-Energy Materials Threatens Biodiversity, Study Shows

by O. Rudgard, September 3, 2020 in ClimateChaneDispatch


Mining for renewable energy materials could threaten biodiversity, researchers have found.

Scientists at the University of Queensland, Brisbane found a high degree of overlap between areas used for mining essential minerals like lithium, which is used for car batteries, and areas with high levels of biodiversity as yet untouched by industry.

Conservationists are “often naive to the threats posed by significant growth in renewable energies”, the researchers said in the study published in the journal Nature Communications, pointing out that 14 percent of protected areas contain metal mines or have them nearby.

Overall, the researchers found that eight percent of mining areas were within the range of areas designated as protected by national governments, and seven percent were within the same range of key biodiversity areas.

Using this metric, 50 million square kilometers of the earth’s land surface is influenced by mining, with 82 percent of mining areas focused on elements needed for renewable energy production.

Elements including lithium, cobalt, and nickel are essential for rechargeable batteries, which are used for power storage in wind and solar projects, as well as in electric cars.

New mines are planned to target these substances, adding to the global surface area covered by mining activities.

The Dutch have decided: Burning biomass is not sustainable

by D. Janssen, July 21, 2020 in Euractiv


The Netherlands should phase out the use of biomass for generating electricity as soon as possible, the advisory board of the Dutch government said in a report presented earlier this month.

Biomass is an “indispensable” resource for the circular economy, but burning it is wasteful.

That is the main message of the report issued on 8 July by the Socio-Economic Council (SER), an independent advisory board of the Dutch government consisting of entrepreneurs, employees and independent experts.

In the chemical industry, the building sector and agriculture, biological materials are crucial for the transition to a circular economy, the council writes. But sustainably produced biomass is too scarce to keep using it for the production of heat or electricity, for which other low-carbon and renewable alternatives exist, the report states.

Accordingly, the billions worth of subsidies that were intended for biomass combustion plants should be phased out as well, the advisors say, calling however for measures to preserve “investment security” when designing a phase-out plan.

This means compensation should be handed out to companies who stand to lose out from the abrupt end of bioenergy subsidies.

Folly: Germany Plans To Convert Coal Power Plant To Burn 100-Year Old Trees In Minutes!

by Die kalte Sonne, June 16, 2020 in NoTricksZone


German Coal Power Plants To Be Converted: To Burn Trees

 

On May 2, 2020, we reported on the movie Burned. In the USA, the focus is on biomass.

However, they do not ferment fast-growing plants into gas as is the case in Europe, rather they cut down trees and burn them in power plants – often together with other things like car tires or soaked railway ties.

The issue is controversial because it is about pure ideology. Climate organisations such as 350.org, which in the USA is like Fridays For Future (FFF) in Europe, have given their blessing to this type of power generation.

The film Planet of the Humans by Michael Moore also denounces this.

Converting CO2 sinks instantly into atmospheric CO2

And so the USA is losing valuable carbon sinks and biotopes, destroying its environment and lying to itself about sustainability and the climate. A tree that takes 50 – 100 years to become big and stately, but then is burned up in a few minutes, can never have a favorable climate balance, no matter how you calculate it. Trees are the new coal, it seems.

But anyone who thinks that this is only done in the USA, where huge forests and thus carbon sinks are destroyed, is mistaken.

“Madness”: German coal plant to be converted to burn trees

The online daily Weserkurier reports on a coal-fired power station in Wilhelmshaven (North Germany) that is to be converted to burn wood. This made Germany’s most famous forester, Peter Wohlleben (book “The Secret Life of Trees“) flash with anger on Twitter.

Renewable energy development threatens many globally important biodiversity areas

by Rehbein J.A. et al., March 2020, in GlobalChangeBiology


Transitioning from fossil fuels to renewable energy is fundamental for halting anthropogenic climate change. However, renewable energy facilities can be land‐use intensive and impact conservation areas, and little attention has been given to whether the aggregated effect of energy transitions poses a substantial threat to global biodiversity. Here, we assess the extent of current and likely future renewable energy infrastructure associated with onshore wind, hydropower and solar photovoltaic generation, within three important conservation areas: protected areas, Key Biodiversity Areas and Earth’s remaining wilderness. We identified 2,206 fully operational renewable energy facilities within the boundaries of these conservation areas, with another 922 facilities under development. Combined, these facilities span and are degrading 886 protected areas, 749 Key Biodiversity Areas, and 40 distinct wilderness areas. Two trends are particularly concerning. First, while the majority of historical overlap occurs in Western Europe, the renewable electricity facilities under development increasingly overlap with conservation areas in South East Asia, a globally important region for biodiversity. Second, this next wave of renewable energy infrastructure represents a ~30% increase in the number of protected areas and Key Biodiversity Areas impacted and could increase the number of compromised wilderness areas by ~60%. If the world continues to rapidly transition towards renewable energy these areas will face increasing pressure to allow infrastructure expansion. Coordinated planning of renewable energy expansion and biodiversity conservation is essential to avoid conflicts that compromise their r​e​s​p​e​c​t​

Fantasy Wish List Masquerades as Climate Poll

by Donna Laframboise, June1, 2020 in BigPicturesNews


Green lobby group invites public to endorse green fantasies.

Last week, a raft of newspaper headlines declared “Canadians still support climate action: poll.” We are intended to believe that “COVID-19’s economic and health challenges haven’t diminished” ordinary people’s enthusiasm for green policies. But this poll has oodles of problems.

First, it was sponsored by Clean Energy Canada. Embedded within the term clean energy is the philosophical argument/political statement/moral judgment that our current, dominant forms of fossil fuel-based energy are dirty.

A ‘clean energy’ outfit isn’t neutral. Its entire purpose is to promote some ideas and to disparage others. What actually happened here is an organization with an agenda drew up a fantastical wish list, and then invited Canadians to agree that the items on that wish list are awesome.

Big surprise that lots of people think upgrading broadband Internet service and public transit are a good idea – especially when the pollster, Abacus Data, declares them “part of an effort to attract companies to invest and grow businesses in Canada.”

Big surprise that lots of people like the idea of “Creating more spaces in towns and cities where people can walk and cycle without fear of vehicles.” But the realistic questions, surely, are:

Destroying the environment to save it

by Ch. Rotter, May 31, 2020 in WUWT


Pseudo-green energy will wreak devastation, pretending to prevent exaggerated climate harm

Paul Driessen

“We had to destroy the village in order to save it.” The infamous Vietnam era quotation may or may not have been uttered by an anonymous US Army major. It may have been misquoted, revised, apocryphal or invented. But it quickly morphed into an anti-war mantra that reflected attitudes of the time.

For Virginians and others forced to travel the path of “clean, green, renewable, sustainable” energy, it will redound in modern politics as “We had to destroy the environment in order to save it.”

Weeks after Governor Ralph Northam signed Virginia’s “Clean Economy Act,” which had been rushed through a partisan Democrat legislature, Dominion Energy Virginia announced it would reach “net zero” greenhouse gas emissions by 2050. To do so, the utility company will raise family, business, hospital and school electricity bills by 3% every year for the next ten years – as these customers and state and local governments struggle to climb out of the financial holes created by the ongoing Coronavirus lockdown.

Just as bad, renewable energy mandates and commitments from the new law and Dominion’s “integrated resource plan” will have major adverse impacts on Virginia and world environmental values. In reality, Virginia’s new “clean” economy exists only in fantasy land – and only if we ignore “clean” energy CO2 emissions, air and water pollution, and other environmental degradation around the world.

Dominion Energy plans to expand the state’s offshore wind, onshore solar and battery storage capacity by some 24,000 megawatts of new “renewable” energy by 2035, and far more after that. It will retain just 9,700 MW of existing natural gas generation, and only through 2045, build no new gas-fired units, and retire 6,200 megawatts of coal-fired generation. This will reduce in-state carbon dioxide emissions, but certainly won’t do so globally. The company intends to keep its four existing nuclear units operating.

To “replace” some of its abundant, reliable, affordable fossil fuel electricity, Dominion intends to build at least 31,400 megawatts of expensive, unreliable solar capacity by 2045. The company estimates that will require a land area some 25% larger than 250,000-acre Fairfax County, west of Washington, DC. That means Dominion Energy’s new solar facilities will blanket 490 square miles (313,000 acres) of beautiful croplands, scenic areas and habitats that now teem with wildlife.

Climate Scientists Try to Rescue Renewable Energies from ‘Planet of the Humans’

by A. Watts, May 14, 2020 in WUWT


“The cause” of climate alarmism and forced energy transformation has been pushed backward by a very long overdue hard look at renewable energy as a mass substitute for mineral energies. Being dilute and intermittent, renewables have more bad secrets than any closet could hold. Small wonder; renewable energies chew up the earth’s surface and creatures in a way that leads to the joke:

Q. “When is an environmentalist not an environmentalist?” A. “When it comes to industrial wind turbines and solar farms.”

Moore’s Planet of the Humans all but ensures that DC-based Big Environmentalism will frontally reject biomass/biofuels, their loss-leader to try to prop up wind and solar as viable. Remove biomass from “green” portfolios and it gets a little skinnier for the business cronies.

And if Big Environmentalism loses wind, the supply-side ruse is over, and people will reconsider climate science given that the ‘cure’ is gone. Hence Michael Mann versus Michael Moore’s Planet of the Humans, the gist of Maxime Joselow’s “Michael Moore’s documentary irks climate scientists” (May 5, 2020).

Transition énergétique : une régression sans précédent ?

par J.P. Bardinet, 16 janvier 2020 in Contrepoints


L ’éolien ne sert à rien et la politique gouvernementale, voulue par l’Union européenne, Emmanuel Macron et ses deux prédécesseurs, est néfaste pour notre pays.

Lors de son évolution, l’humanité a utilisé des énergies primaires avec des densités énergétiques de plus en plus fortes : bois, charbon, gaz, pétrole, uranium. La densité énergétique des énergies renouvelables (EnR), éolien et solaire, est très faible, ce qui est une régression sans précédent dans l’histoire de l’humanité.

Chiffres de production totale RTE 2018 : 548,6 TWh dont

  • nucléaire 71,7 %
  • thermique à combustible fossile 7,2 %
  • hydraulique 12,5 %
  • éolien 5,1 %
  • solaire 1,9 %
  • agroénergies 1,8 %

Le facteur de charge de l’éolien est de 21 % et celui du solaire de 13,6 %.

Ces EnR intermittentes ont de faibles facteurs de charge, ce sont donc des moyens de production peu efficaces, mais particulièrement onéreux.
L’Espagne et l’Allemagne en ont fait la douloureuse expérience.

Avant le développement des EnR intermittentes, nous exportions environ 10 % de notre production d’électricité. Nous pouvons donc nous demander pourquoi nos gouvernants, à la suite des Directives de la Commission européenne, ont imposé  manu militari ces EnR intermittentes alors qu’une politique de prolongation de la durée de vie des centrales nucléaires, un programme de construction de plusieurs EPR, et un financement approprié de la R&D sur la surgénération à uranium appauvri auraient été les meilleures options.

La filière des SMR (small size reactors) qui utilise la technologie des sous-marins nucléaires, serait également une piste à développer, car elle permettrait de produire de l’électricité à proximité des centres de consommation, rendant ainsi les pertes lors du transport quasiment nulles.

LE CO2 LOURDEMENT TAXÉ

Les politiques climat-énergie de notre pays et de la plupart de pays de l’UE sont basées sur l’hypothèse non prouvée que nos émissions de CO2 ont une action mesurable sur la température moyenne annuelle globale (TMAG) et sur le climat de notre planète.

China has slashed clean energy funding by 39%, leading a global decline

by From MIT Technology review, July 12, 2019 in WUWT


The big picture: The new report suggests last year’s slowdown in renewable-energy construction has extended into 2019, taking the world in exactly the wrong direction at a critical time (see “Global renewables growth has stalled—and that’s terrible news”). Every major report finds that the world needs to radically accelerate the shift to clean energy to have any hope of not blowing past dangerous warming thresholds (see “At this rate, it’s going to take 400 years to transform the energy system”).

GLOBAL INVESTMENT IN GREEN ENERGY DROPS SHARPLY

by GWPF, July 12, 2019 in FinacialTimes


Investment in clean energy slipped to $117.6bn, a decline of 14 per cent compared with the same period last year, according to new research from Bloomberg New Energy Finance.

A sudden change in China’s renewable energy policies last year — when it curbed solar and wind subsidies — has dramatically reduced the number of new projects in the world’s largest market.

Clean energy investment in China was down 39 per cent during the first half of this year, compared with the same period last year.

However, those figures could improve later this year, suggested Justin Wu, BNEF’s head of Asia-Pacific.

Climate change puts pressure on Europe’s energy system

by European Environment Agency, June 18, 2019


All parts of Europe’s energy system, from availability of energy sources to energy consumption, are potentially vulnerable to climate change and extreme weather events, according to a European Environment Agency report, published today. To secure reliable supply of clean energy, Europe’s energy system needs to adapt and become more climate resilient, the report states.

The EEA assessment ‘Adaptation challenges and opportunities for the European energy system’ analyses the needs for climate change adaptation and climate resilience in Europe’s energy system now and in the future. This assessment supports the clean energy transition, which involves a massive expansion of renewable energy sources, many of which are sensitive to climate factors.

The new assessment warns that climate change and extreme weather events increasingly affect all parts of the European energy system. The most important changes include increases in mean and extreme air and water temperatures, and changes in water availability, extreme climate‑related events, and coastal and marine hazards. These changes will affect the availability of primary energy sources — especially renewable energy sources — as well as the transformation, transmission, distribution and storage of energy, and energy demand.

Without Mining, There Is No ‘Green Revolution’

by S. Moore A. & Bridges, June17, 2019 in ClimateChangeDispatch


The recent threats by Beijing to cut off American access to critical mineral imports has many Americans wondering why our politicians have allowed the United States to become so overly-dependent on China for these valued resources in the first place.

Today, the United States is 90 percent dependent on China and Russia for many vital “rare earth minerals.”

The main reason for our over-reliance on nations like China for these minerals is not that we are running out of these resources here at home. The U.S. Mining Association estimates that we have at least $5 trillion of recoverable mineral resources.

The U.S. Geological Survey reports that we still have up to 86 percent or more of key mineral resources like copper and zinc remaining in the ground, waiting to be mined.

These resources aren’t on environmentally sensitive lands, like national parks, but on the millions of acres of federal, state and private lands.

The mining isn’t happening because of extremely prohibitive environmental rules and a permitting process that can take 5-10 years to open a new mine. Green groups simply resist almost all new drilling.

What they may not realize is that the de facto mining prohibitions jeopardize the “Green Energy Revolution” that liberals so desperately are seeking.

How is this for rich irony: To make renewable energy at all technologically plausible, will require massive increases in the supply of rare earth and critical minerals.

EIA data shows wind & solar met 3% of U.S. energy after $50 billion in subsidizes

by Larry Hamlin, June 6, 2019 in WUWT


The EIA AEO 2019 report shows that in year 2018 wind and solar energy resources provide about 3% of U.S. total energy consumption while fossil fuel energy resources provide about 81% of total energy use.

The dominate use of fossil fuels in meeting U.S. energy needs remains little changed from a decade ago before use of renewable energy resources became mandated and supported by lucrative government subsidizes.

Using additional EIA data the total wind and solar provided energy going back to year 2000 is available which allows an assessment of the Production Tax Credit (PTC) payments to be made.

German Employer’s Association Op Ed: “No Expert Politician In Berlin Believes In Switch To Green Energies Any More”

by P. Gosselin, May 14, 2019 in NoTricksZone


As the pressure mounts in Germany to switch off coal power plants and to rapidly transition over to green energies, one gets the feeling that it all has more to do with a desperate, last-ditch effort by the green energy proponents to rescue their pet green project.

Behind closed doors, no one in Berlin believes in it

Now, just days ago, energy expert Dr. Björn Peters wrote at the German Association of Employers site that the Energiewende has deteriorated to the point that: “No specialist politician in Berlin believes in the success of the Energiewende any more. Whoever you ask, everyone says this only behind closed doors and thinks that if you go to the press with it you can only lose against the ‘green’ media mainstream.”

Peters warns that what is needed in Germany is a good dose of reality and “a fresh start on energy policy.”

Advantages of fossil fuels “too great”

The German expert writes that despite the hundreds of billions of euros committed to green energies, “chemical energy from coal, oil and gas supplies about four fifths of primary energy worldwide and also in Germany and thus represents the present energy supply”.

Nuclear power excluded from EU’s green investment label

by C. Stam & A. Prager, April 3, 2019 in EurActiv


The text voted in Parliament also excludes fossil fuels and gas infrastructure from the EU’s proposed green finance taxonomy, which aims to divert investments away from polluting industries into clean technologies.

In a bid to prevent “green-washing”, the Parliament text also requires investors to disclose whether their financial products have sustainability objectives, and if they do, whether the product is consistent with the EU’s green assets classification, or taxonomy.

While activists applauded the move, they said the classification voted by the European Parliament was too narrow and applies only to a limited set of recognisable green assets, such as wind and solar power companies.

“Brown list” rejected

An amendment to publish a “brown list” to name and shame investments seen as damaging for the environment was rejected by Parliament.

La voiture à hydrogène est un miroir aux alouettes de la transition énergétique

by Olivier Daniélo, 2 avril 2019 in Reporterre


Il y a urgence à agir pour réduire les émissions de CO2. La marche et le vélo sont certes préférables à la voiture particulière. Mais parmi les différents types de voitures, quelle est la solution la plus efficace pour réduire les émissions de CO2 ?

Il existe un indicateur particulièrement intéressant pour tenter d’y répondre : la quantité d’énergie consommée pour réaliser par exemple 200.000 kilomètres. Energie non seulement pour propulser la voiture, mais aussi pour fabriquer la voiture elle-même et extraire dans les mines les matières premières nécessaires. Le bilan carbone est bien entendu corrélé au bilan énergétique. Les experts du groupe Volkswagen (VW) ont fait le calcul et ont présenté les résultats le 12 mars 2019 à l’occasion de la conférence de presse annuelle de ce mastodonte dont les décisions influencent l’industrie automobile mondiale.

 

 

 

Verdict : la voiture aux carburants synthétiques (eFuel et eCNG) consomme trois fois plus d’énergie primaire que la voiture électrique. Et celle à l’hydrogène, 1,7 fois plus. Ces 70 % supplémentaires représentent un impact à la fois économique et carbonique. La fabrication de la pile à combustible et du réservoir capable de résister à une pression de 700 atmosphères est énergivore. La voiture à hydrogène la plus vendue au monde (quelques milliers d’exemplaires) pèse 1.850 kg, soit 3 kilos de plus que la Tesla Model 3 Long Range (100 % batterie), qui a la même autonomie. Mais, c’est surtout le mauvais rendement de la chaîne hydrogène qui plombe le bilan global.

La transition électrique européenne, une impasse?

by J.P. Schaeken Willemaers, 29 mars 2019 in ScienceClimatEnergie


La transition énergétique est abondamment traitée dans les médias, souvent de manière univoque (ce que d’aucuns appellent le débat confisqué) en ignorant les conséquences socio-économiques. Dans ce papier, nous nous limiterons à sa composante électrique.
Rappelons tout d’abord que la finalité première d’un système électrique est d’assurer l’adéquation entre la production et la consommation d’électricité.


Il va de soi, quoique ce ne soit pas évident pour tout le monde, qu’il faut anticiper les adaptations nécessaires du système avant de procéder à la mise en œuvre du changement. Dans ce processus, l’analyse de l’impact sur la transmission et la distribution d’électricité et sur la continuité des services ainsi que la réalisation des travaux correspondants requis, sont prioritaires. Or aucun gouvernement ayant décidé de réduire drastiquement les émissions de gaz à effet de serre (GES), ne s’est soucié des conséquences de leurs décisions. Ceci explique les déboires des pays qui se sont précipités dans une stratégie de pénétration accélérée de production d’électricité renouvelable intermittente.

Report : The “New Energy Economy”: An Exercise in Magical Thinking

by Mark P. Mills, March 26, 2019 in ManhattanInstitute


EXECUTIVE SUMMARY

A movement has been growing for decades to replace hydrocarbons, which collectively supply 84% of the world’s energy. It began with the fear that we were running out of oil. That fear has since migrated to the belief that, because of climate change and other environmental concerns, society can no longer tolerate burning oil, natural gas, and coal—all of which have turned out to be abundant.

So far, wind, solar, and batteries—the favored alternatives to hydrocarbons—provide about 2% of the world’s energy and 3% of America’s. Nonetheless, a bold new claim has gained popularity: that we’re on the cusp of a tech-driven energy revolution that not only can, but inevitably will, rapidly replace all hydrocarbons.

This “new energy economy” rests on the belief—a centerpiece of the Green New Deal and other similar proposals both here and in Europe—that the technologies of wind and solar power and battery storage are undergoing the kind of disruption experienced in computing and communications, dramatically lowering costs and increasing efficiency. But this core analogy glosses over profound differences, grounded in physics, between systems that produce energy and those that produce information.

In the world of people, cars, planes, and factories, increases in consumption, speed, or carrying capacity cause hardware to expand, not shrink. The energy needed to move a ton of people, heat a ton of steel or silicon, or grow a ton of food is determined by properties of nature whose boundaries are set by laws of gravity, inertia, friction, mass, and thermodynamics—not clever software.

This paper highlights the physics of energy to illustrate why there is no possibility that the world is undergoing—or can undergo—a near-term transition to a “new energy economy.”

Among the reasons:

REPORT: GREEN ENERGY ECONOMY IS SIMPLY ‘IMPOSSIBLE’

by Mark P. Mills, March 23, 2019 in GWPF


Hydrocarbons—oil, natural gas, and coal—are the world’s principal energy resource today and will continue to be so in the foreseeable future. Wind turbines, solar arrays, and batteries, meanwhile, constitute a small source of energy, and physics dictates that they will remain so. Meanwhile, there is simply no possibility that the world is undergoing—or can undergo—a near-term transition to a “new energy economy.”

The Green New Deal’s Weak Chain Of Logic

by Daniel G. Jones, March 18, 2019 in ClimateChangeDispatch


Reagan observed: “It isn’t so much that liberals are ignorant. It’s just that they know so many things that aren’t so.”

So it is with the Green New Deal. Most liberals regard it as a simple proposition: Global warming is a really big problem, and it’s our fault, so let’s fix it.

But closer analysis reveals that the argument for the Green New Deal rests upon a long chain of interdependent assertions, every one of which must be believed for the problem to be of sufficient peril to warrant their drastic solution.

Here are links in their chain of logic. If you doubt the truth of any single step, you must discard the entire argument.

Unreliable Power Source…Adding Capacity Does Little To Solve Germany’s Green Energy Power Gaps

by P. Gosselin, March 6, 2019 in NoTricksZone


German wind park protest group MenschNatur posted here explaining how even adding more wind and solar capacity does not make Germany’s energy supply any more reliable, but in fact may even make it less so.

Time and again the proponents of the Energiewende (transition to green energies) promote the idea that we must invest massively in more wind and solar power plants and that only an accelerated expansion can save the transformation to green energies.

Thus the wind energy protest group MenschNatur has taken a closer look at the increase in installed nominal capacity over the past years and compared it to what actually gets fed into the grid.

How increases in wind generator capacity affects the feed-in power is described in the following diagram. MenschNatur plotted the installed capacity of all German onshore wind turbines from 2014 to 2018, along with what actually got fed in.

Captured carbon dioxide converts into oxalic acid to process rare earth elements

by Michigan Technological University, February 22, 2019 in ScienceDaily


Until now, carbon dioxide has been dumped in oceans or buried underground. Industry has been reluctant to implement carbon dioxide scrubbers in facilities due to cost and footprint.

What if we could not only capture carbon dioxide, but convert it into something useful? S. Komar Kawatra and his students have tackled that challenge, and they’re having some success.

China: No Wind Or Solar If It Can’t Beat Coal On Price

by  John Parnell, January 10, 2019 in Forbes


China has said it will not approve wind and solar power projects unless they can compete with coal power prices.

Beijing pulled the plug on support for large solar projects, which had been receiving a per kWh payment, in late May. That news came immediately after the country’s largest solar industry event and caught everyone by surprise.

Officials are understood to have been frustrated at seeing Chinese suppliers and engineering firms building solar projects overseas that delivered electricity at prices far below what was available back home.

Can wind and solar replace fossil fuels?

by Richard Patton, January 1, 2019 in WUWT


Statements implying that wind and solar can provide 50% of the power to the grid are not difficult to find on the internet. For example, Andrew Cuomo announced that

“The Clean Energy Standard will require 50 percent of New York’s electricity to come from renewable energy sources like wind and solar by 2030…”

Considering that the wind is erratic, and the solar cells only put out full power 6 hours per day, it seems a remarkable statement. Can intermittent energy actually supply that much power?

For some answers, we turn to Germany, which has some of the highest electric bills in the world as well as a high proportion of its electric power produced by wind and solar (19%). Let’s take a look at German consumption and generation.
