The unsubsidised cost of wind and solar now
beats coal as the cheapest form of bulk generation in all major
economies except Japan, according to the latest levellised cost of
electricity analysis by leading energy analyst BloombergNEF.
The latest report says the biggest news comes in the two fastest
growing energy markets, China and India, where it notes that “not so
long ago coal was king”. Not any more.
“In India, best-in-class solar and wind plants are now half the cost
of new coal plants,” the report says, and this is despite the recent
imposition of import tariffs on solar cells and modules.
The China experience is also significant. While local authorities
have put a brake on local installations, causing the domestic market to
slump by one third in 2018, this has created a “global wave of cheap
equipment” that has more than compensated for increased financing costs
caused by rising interest rates.
The cost of battery storage is also falling – so much so that in
countries like Australia and India, pairing unsubsidised wind and solar
with four hours of battery storage can be cost competitive with new coal
or gas plants.
“Short-duration batteries are today the cheapest source of new
fast-response and peaking capacity in all major economies except the US,
where cheap gas gives peaker gas plants an edge. As electric vehicle
manufacturing ramps-up, battery costs are set to drop another 66 per
cent by 2030, according to our analysis,” the report says.
This is stunning stuff. BloombergNEF’s assessment of the ability of
wind, solar and storage to beat new fossil fuel plants in Australia
comes nearly a full decade before the prediction made by the Australian
Energy Market Operator in its Integrated System Plan.
It would also suggest that the only hope that the current federal
Coalition government has in trying to encourage new investment in coal
is for upgrades and extensions of existing coal plant, which may become
the limit of its rushed attempts to contract new “24/7” or “fair dinkum”
generation.
(RenewEconomy sought more information about the estimated costs, but the report details have been reserved for clients).
BloombergNEF says the emergence of battery storage as a source of
peak power and flexible capacity means that the costs of these services
will fall to levels never reached before by conventional fossil-fuel
peaking plants.
“Batteries co-located with PV or wind are becoming more common,” the report says.
“Our analysis suggests that new-build solar and wind paired with
four-hour battery storage systems can already be cost competitive,
without subsidy, as a source of dispatchable generation compared with
new coal and new gas plants in Australia and India.
The Bloomberg analysis follows quickly on the heals of the recent
annual Lazard uptake, and the voluminous World Energy Outlook from the
more conservative International Energy Agency. All three come to the
same conclusions: wind and solar and storage will beat out fossil fuels.
Globally, BloombergNEF says the benchmark global levellised cost of
new PV (no-tracking) has fallen 13 per cent from the first half of the
year to $US60/MWh, although the lowest costs occur in countries with
excellent solar resources such as Australia.
This graph above shows the costs in China, where solar and wind have now
begun to challenge coal, beat nuclear and also gas. If the combination
of solar and battery appears to put it out of the market, this next
graph may provide some context, as it shows the comparison between
battery storage and the current choice of meeting peak demand, gas
peakers.
It shows that for short one hour durations, battery storage is
already easily the cheapest, and as battery costs continue to fall, even
four hour battery storage will beat the current thermal options for
meeting demand peaks and fast response.
BloombergNEF’s benchmark global levelized cost for onshore wind sits
at $US52/MWh, a six per cent fall from its analysis six months ago,
thanks to cheaper turbines and a stronger US dollar. The technology is
now as cheap as $US27/MWh in India and Texas, without subsidy.
In the US, even with cheap shale gas, wind beats combined-cycle gas
plants (CCGT) as a source of new bulk generation. And if the gas price
rises above $US3/MMBtu, BloombergNEG suggest existing CCGT are going to
run the risk of becoming rapidly undercut by new solar and wind.
“This means fewer run-hours and a stronger case for flexible
technologies such as gas peaker plants and batteries that do well at
lower utilization (capacity factor),” it says.
In the Asia-Pacific, gas is more expensive which means that new-build
combined-cycle gas plants with a levelized cost of $US70-117/MWh
continue to be less competitive than new coal-fired power at
$US59-81/MWh. This remains a major hurdle for reducing the carbon
intensity of electricity generation in this part of the world.
BlombergNEF’s LCOE analysis covers nearly 7,000 projects across 20 technologies and 46 countries globally.
With wildfires, heat waves, and rising sea levels, large tracts of the earth are at risk of becoming uninhabitable. But the fossil-fuel industry continues its assault on the facts.

Thirty years ago, this magazine published "The End of Nature," a long
article about what we then called the greenhouse effect. I was in my
twenties when I wrote it, and out on an intellectual limb: climate
science was still young. But the data were persuasive, and freighted
with sadness. We were spewing so much carbon into the atmosphere that
nature was no longer a force beyond our influence—and humanity, with its
capacity for industry and heedlessness, had come to affect every cubic
metre of the planet’s air, every inch of its surface, every drop of its
water. Scientists underlined this notion a decade later when they began
referring to our era as the Anthropocene, the world made by man.
I was frightened by my reporting, but, at the time, it seemed likely
that we’d try as a society to prevent the worst from happening. In 1988,
George H. W. Bush, running for President, promised that he would fight
“the greenhouse effect with the White House effect.” He did not, nor did
his successors, nor did their peers in seats of power around the world,
and so in the intervening decades what was a theoretical threat has
become a fierce daily reality. As this essay goes to press, California
is ablaze. A big fire near Los Angeles forced the evacuation of Malibu,
and an even larger fire, in the Sierra Nevada foothills, has become the
most destructive in California’s history. After a summer of
unprecedented high temperatures and a fall “rainy season” with less than
half the usual precipitation, the northern firestorm turned a city
called Paradise into an inferno within an hour, razing more than ten
thousand buildings and killing at least sixty-three people; more than
six hundred others are missing. The authorities brought in cadaver dogs,
a lab to match evacuees’ DNA with swabs taken from the dead, and
anthropologists from California State University at Chico to advise on
how to identify bodies from charred bone fragments.
For the past few years, a tide of optimistic thinking has held that
conditions for human beings around the globe have been improving. Wars
are scarcer, poverty and hunger are less severe, and there are better
prospects for wide-scale literacy and education. But there are newer
signs that human progress has begun to flag. In the face of our
environmental deterioration, it’s now reasonable to ask whether the
human game has begun to falter—perhaps even to play itself out. Late in
2017, a United Nations agency announced that the number of chronically
malnourished people in the world, after a decade of decline, had started
to grow again—by thirty-eight million, to a total of eight hundred and
fifteen million, “largely due to the proliferation of violent conflicts
and climate-related shocks.” In June, 2018, the Food and Agriculture
Organization of the U.N. found that child labor, after years of falling,
was growing, “driven in part by an increase in conflicts and
climate-induced disasters.”

It may feel sad but not the end of the word to lose a few species of
plants or animals from global warming. It’s a crowded world, right?
Plenty of species are dying out and life goes on is a common fatalist
mantra.
But a new study from Australia and Italy has proved that idea horribly wrong.
Researchers
from Australia and Italy created 2000 virtual Earths (variations of the
planet we live on) and then subjected them to different stresses such
as runaway global warming, nuclear winter following the detonation of
multiple atomic bombs, and a large asteroid impact.
The domino effect
Each
scenario came to the same disturbing conclusion: plant or animal
species killed off by extreme environmental change dramatically
increases the risk of an extinction domino effect that could annihilate
all life on Earth.
Once certain species fell to oblivion, others followed – and the whole system eventually collapsed.
Even when some species were blessed with artificial adaptations to climate change, the mass of life was lost.
“Even
the most resilient species will inevitably fall victim to the synergies
among extinction drivers as extreme stresses drive ecosystems to
collapse,” said lead author Dr Giovanni Strona of the European
Commission’s Joint Research Centre based in Ispra, northern Italy.
The co-extinction syndrome
As
a statement from Finders University in Adelaide put it: “This is the
worst-case scenario of what scientists call ‘co-extinctions’, where an
organism dies out because it depends on another doomed species.”
The findings were published this week in the journal Scientific Reports.
Professor
Corey Bradshaw is the Matthew Flinders Fellow in Global Ecology at
Flinders University. He and his team develop models to predict ecosystem
function, resilience, and change in the past, present, and future.
Dr Bradshaw told The New Daily that working with a virtual Earth allowed the team to do any “crazy God-like experiment” they wanted.
“And
so we’d take out species at random and see what happened,” he said.
“We’d do that progressively until we got a full extinction curve for all
life.”
The speediest end
The quickest way to kill the planet, he said, was taking out the most ecologically important species first.
“They’re
the ones with the most connections in a network. Losing them is the
worst-case scenario. When something that is only connected to one or two
species dies off, it isn’t going to be missed so much,” Dr Bradshaw
said.
When the team warmed up the planet, they found that warming
“effectively mimicked the experiment where we knocked out the
ecologically most important species. This is what surprised us: warming
turns out to be the worst case scenario”.
The beginning of the end
comes with the loss of plant life. “Plants have a low tolerance to
temperatures at the top end. When you knock out certain plant
communities, the herbivores have nothing to eat. Then the predators that
eat the herbivores have nothing to eat.”
As the world warms up,
it’s the trees that will begin to die out in greater numbers. “A tree
can only stand a couple of days above 45 degrees. If that heatwave lasts
a couple of weeks, they’re wiped out. Then all the things that live in
the trees, the bird and insects, they all go as well. Warming is the
worst because it affects the plants the most.”
Dr Bradshaw said
that failing to take into account these co-extinctions means we are
underestimating the rate and magnitude of the loss of entire species
from events like climate change “by up to 10 times.”
He said that
humans had evolved to not think about the worst-case scenario “because
it’s psychologically stressful” and easier to say that things will never
get so bad.
“But not taking into account this domino effect gives
an unrealistic and exceedingly optimistic perspective about the impact
of future climate change.”
In a statement, Dr Strona said: “In the
case of global warming in particular, the combination of intolerance to
heat combined with co-extinctions mean that five to six degrees of
average warming globally is enough to wipe out most life on the planet.”

There’s a reason that few people are thinking about world grain
supplies. Last year saw record worldwide production of grains and record
stocks of grains left over.
But this year worldwide production slipped about 2 percent, owing in
large part to the plunge in Australia’s production caused by an ongoing
severe drought. Production is expected to fall 23 percent.
Fortunately, in our globalized grain markets, this hasn’t affected
overall supplies or prices very much as grain stocks are high and
supplies are mobile and shipped all over the world as needed.
But Australia is the world’s fifth largest wheat exporter, accounting
for nearly 9 percent of the total in 2016 according to the Food and Agriculture Organization of the United Nations.
In fact, the top five wheat exporting countries account for 56 percent
of world wheat exports. The rest of the world is highly dependent on
these exporters to make up the difference between what they grow and
what they eat.
But it’s not just wheat. For rice the numbers are even more striking.
The top five rice exporting countries supplied nearly 80 percent of
total world exports. For corn (called maize in most countries) the
number is a bit higher. The top five corn exporting countries supplied
almost 81 percent of all exports.
Why is this important? First, about 80 percent of all calories consumed come from grains,
either through direct consumption (46 percent) or indirectly through
livestock in the form of meat, milk, eggs and other animal products (33
percent). Second, as climate change begins to scorch the major grain
growing areas of the world, the large exporters may find themselves with
much less to export or even begin competing for imports. One major study
forecasts that wheat, soybean and corn production in the United
States—the world’s largest exporter of soybeans and corn and the second
largest exporter of wheat—could drop between 22 and 49 percent by the
end of the century. By 2030 combined rice, corn and wheat harvests in China could drop by 8 percent.
China is, of course, a major consumer of grains and the world’s 13th
largest rice exporter. Perhaps most worrying of all is the possibility
that there will be a rising likelihood of simultaneous crop failures in several major growing areas.
This all comes in the face of world population projections of 9.8 billion in 2050 and 11.2 billion in 2100 compared to 7.7 billion today.
These projections, however, are based on smooth sailing from today
forward, something that climate change and all its attendant effects
call into question. If food supplies are declining in the coming
decades, these population projections hardly seem credible.
The vulnerability we face comes not only from perilous conditions
stemming from climate change, but also, of course, from the
concentration of the growing areas for our main sources of food
calories. It is true that every country grows some of its own food. But
the emerging picture of climate change suggests that in the future those
who do not grow enough of their own food may not be able to count on
those who currently grow more than they need to make up the difference.
This would imply a necessity for a move toward self-sufficiency, that
is, eating what can be grown in one’s own soil; an end to the
destruction of farmland for so-called “development;” a move away from
grain-intensive livestock-based foods; and the enlisting of many more
people into the production of food.
Today, for the globe as a whole, all these trends are moving in the wrong direction.
‣Voters prioritize lower electricity bills over emission cuts ‣Ruling coalition narrows poll gap with Labor as election nears

A new poll shows Australian Prime Minister Scott Morrison’s focus on
getting power bills down may be starting to pay dividends. But it also
suggests his failure to establish a coherent narrative on tackling
climate change could hurt his government at the ballot box.

Morrison’s predecessor Malcolm Turnbull was ousted as prime minister
in August after an internal rift in the ruling Liberal Party over energy
policy -- specifically his plan to include carbon emission reduction
targets in the now-abandoned National Energy Guarantee.
When Morrison appointed Angus Taylor to the energy portfolio,
he gave him the snappy informal title of “minister for reducing
electricity prices.” Morrison and Taylor both say the nation can’t
depend on renewable energy, instead touting coal as power you can rely
on “when the sun isn’t shining and the wind isn’t blowing.”
Monday’s
poll will offer Morrison encouragement that he’s closing down the main
opposition Labor party’s lead ahead of a national election expected in
May next year. The poll showed Labor’s lead over the ruling coalition
narrowing to a 52-48 split on a two-party preferred basis, from 55-45 in
October.
Cheap Power Trumps Climate Concerns Poll asks what should be the top priority for Australia's energy policy
Fairfax-Ipsos poll
Labor leader Bill Shorten wants more ambitious climate targets than the
government, but has yet to fully flesh out his energy plans. He’s set to
do that this week, when he gives a major speech on energy at a
BloombergNEF event in Sydney on Thursday.
Bill Shorten

Labor voters are far more likely to see climate change as the most
pressing priority for energy policy -- 53 percent in the poll said it
should be the main focus -- so in that sense Shorten is playing to his
base. The challenge for him now is to simultaneously keep up the
pressure on energy suppliers to keep prices contained.
Morrison and Taylor may have earned some credit with voters for exerting pressure
on the big energy retailers, but they are also dealing with a backlash
over their lukewarm attitude toward renewables. Morrison says he is
confident Australia will meet its Paris climate targets -- reducing
emissions by at least 26 percent below 2005 levels by 2030 -- but is yet
to articulate a clear policy for achieving that.

Not heard of the “Extinction Rebellion” before? Then you heard it
here first. Because soon, everyone is going to have heard of it. The Extinction Rebellion
is a non-violent direct action movement challenging inaction over
dangerous climate change and the mass extinction of species which,
ultimately, threatens our own species.
Saturday November 17 2018 is “Rebellion Day”
– when people opposed to what they see as a government of “climate
criminals” aim to gather together enough protesters to close down parts
of the capital – by shutting down fossil-powered road traffic at key
pinch-points in London.
I’m a Reader in Philosophy at the University of East Anglia and I
have thrown myself headfirst into this movement. Our long-term aim is to
create a situation where the government can no longer ignore the
determination of an increasingly large number of people to shift the
world from what appears to be a direct course towards climate calamity.
Who knows, the government could even end up having to negotiate with the rebels.
As someone who is both a veteran of non-violent direct actions over
the years and an academic seeking to make sense of these campaigns, I’ve
been thinking quite a lot about what’s old and what’s new about the
Extinction Rebellion. Here are my conclusions so far.
From world peace to climate justice
The Extinction Rebellion is rooted in longstanding traditions exemplified by the radical nuclear disarmament movement. The founders of the Extinction Rebellion have thought carefully about past precedents, and about what works and what doesn’t.
They’ve noted for instance that you don’t necessarily need active
involvement from more than a tiny percentage of the population to win radical change, provided that you have a righteous cause that can elicit tacit backing from a much larger percentage.
The Extinction Rebellion is also quite different from its
predecessors. True, the disarmament movement was about our very
existence, but nuclear devastation was – and still is – only a risk.
Extinction Rebellion’s aim is to prevent a devastation of our world that will come – and quite soon, unless we manage to do something unprecedented that will radically change our direction.
Climate activists often compare their struggle to victories from the
past. But in my view comparisons which are often made – to Indian
independence, the civil rights movement or the campaign for universal
suffrage, for example – are over-optimistic,
even fatuous. These historical movements were most often about
oppressed classes of people rising up and empowering themselves, gaining
access to what the privileged already had.
The Extinction Rebellion challenges oligarchy and neoliberal
capitalism for their rank excess and the political class for its deep
lack of seriousness. But the changes that will be needed to arrest the
collapse of our climate and biodiversity are now so huge that this
movement is concerned with changing our whole way of life. Changing our diet significantly. Changing our transport systems drastically. Changing the way our economies work to radically relocalise them. The list goes on.
This runs up against powerful vested interests – but also places considerable demands upon ordinary citizens, especially in “developed” countries such as the UK. It is therefore a much harder ask.
This means that the chances of the Extinction Rebellion succeeding are
relatively slim. But this doesn’t prove it’s a mistaken enterprise – on
the contrary, it looks like our last chance.

From the lecture hall to the streets
This all leads into why I sat in the road blocking the entrance to
Parliament Square on October 31, when the Extinction Rebellion was
launched – and why I will be “manning the barricades” again on November
17. As a Quaker, I cherish the opening words of the famous Shaker hymn: Tis the gift to be simple.
What does it mean to live simply at this moment in history? It means to
do everything necessary so that others – most importantly our children
(and their children) – can simply live. It isn’t enough to live a life
of voluntary simplicity.
One needs also to take peaceful direct action to seek to stop the
mega-machine of growth-obsessed corporate capitalism that is destroying
our common future. That’s why it seems plain to me that we need peaceful
rebellion now, so that we and countless other species don’t face
devastation or indeed extinction.
The next line of that Shaker hymn goes: “Tis the gift to be free.” In
our times, to be free means to not be bound by laws that are consigning
our children to purgatory or worse. If one cares properly for one’s
children, that must entail caring for their children, too. You don’t
really care for your children if you damn their children. And that logic
multiplies into the future indefinitely – we aren’t caring adequately for any generation if the generation to follow it is doomed.
As mammals whose primary calling is to care for our kids, it is
therefore logical that an outright existential threat to their future,
and to that of their children, must be resisted and rebelled against, no
matter what the pitifully inadequate laws of our land say.
I’ve felt called upon to engage in conscientious civil disobedience before, at Faslane and Aldermaston against nuclear weapons and with EarthFirst in defence of the redwood forests threatened with destruction in the Pacific Northwest of the USA.
But the Extinction Rebellion seems to me the most compelling cause of them all. Unless we manage to do the near impossible, then after a period of a few decades at most there won’t be any other causes to engage with. It really now is as stark and as dark as that.
If you too feel the call, then I think you now know what to do.
The huge postcard was rolled out on the Switzerland's Aletsch Glacier, which is melting.
It had more than 125,000 individual drawings and messages.
Organizers hoped to set a world record.

More than 125,000 drawings and notes from children around the
world were put together on a glacier in the Swiss Alps on Friday to send
a big message.
The message: Fight climate change and help the environment.
"They are asking us and their leaders to take action to preserve the
planet Earth for them to have a future on it," said Oceane Dayer,
founder of Swiss Youth for Climate.
Kids Leave Climate Change Message in Swiss Alps
125,000 drawings come together to send a large message about climate change in the Swiss Alps.
The mosaic laid out on Switzerland's Aletsch Glacier measured 26,910
square feet, about half the size of a U.S. football field. It was
organized by a non-profit conservation group called the WAVE Foundation
and the Swiss government's Agency for Development and Cooperation.
The Aletsch Glacier is the largest glacier in the Alps, and it is
melting at an alarming rate. Losing nearly 40 feet of ice a year, the
glacier could be gone by the end of the century, experts warn.
The
postcards bore messages of efforts to fight climate change and help the
environment: limiting water use, promises to use public transportation,
or recycling old goods before buying new ones among them. They covered
an area the size of half a U.S. football field. (Fabrice Coffrini/AFP/Getty Images)

laminated in long glued-together strips to protect them from the ice and
snow. Organizers said they hoped to set a Guinness World Record for the
"postcard with the most contributions." (Fabrice Coffrini/AFP/Getty Images)
The project's aim was to "boost a global youth climate movement ahead
of the next global climate conference (COP24) in Poland," next month,
according to the WAVE Foundation.
Organizers said the 125,000 individual postcards set a Guinness World Record for the "postcard with the most contributions."
However, according to the Associated Press, Guinness said the attempt
has not been registered. The current record is only 16,000.

month. (Fabrice Coffrini/AFP/Getty Images)
From overhead, messages spelled out on the card were "Stop global
warming" and "#1.5C," a nod to the goal of keeping global warming below
1.5 degrees Celsius (2.7 degrees Fahrenheit).
