For climate action, renewables clearly beat nuclear power

Heinrich Boll 26th April 2021, Mark Jacobson: New nuclear power costs about 5 times more than onshore wind
power per kWh. Nuclear takes 5 to 17 years longer between planning and operation and produces on average 23 times the emissions per unit electricity generated.

In addition, it creates risk and cost associated with weapons proliferation, meltdown, mining lung cancer, and waste risks. Clean, renewables avoid all such risks.

PNM Resources to replace its Palo Verde nuclear energy with 100% solar and battery


Sierra Club 16th April 2021,
 After announcing it would drop one of its leases in the Palo Verde Nuclear plant last year, this month PNM proposed replacing the energy with 100% solar and battery. In support of its proposal, PNM cited the Energy Transition Act’s requirements and the Public Regulation Commission’s decision last year to choose a 100% solar/storage proposalrather PNM’s favored gas-inclusive replacement scenario for San Juan Generating Station coal. The replacement proposal will need to be approved by the commission. In selecting carbon emission-free generation to replace Palo Verde, PNM states in testimony it has taken into
consideration “the state’s energy transition policies and long-term mandate for a carbon emission-free generation portfolio.” While we have yet to delve into all of the details of PNM’s application, this is very
encouraging and we look forward to supporting PNM’s request for prompt approval of replacement resources.

New solar farm to replace Iowa’s only nuclear power plant: will supply more energy, and many jobs.

Iowa’s only nuclear power plant will be turned into a solar farm, https://electrek.co/2021/03/22/iowas-only-nuclear-power-plant-will-be-turned-into-a-solar-farm/ Michelle Lewis, Mar. 22nd 2021

The Duane Arnold Energy Center in eastern Iowa, a now-idle nuclear power plant, will soon become a 690-megawatt solar farm. The new solar farm plus storage will produce more energy than the single-unit 615-megawatt nuclear plant generated, which powered more than 600,000 homes.

The new solar plan

Owner NextEra Energy of Florida will build the solar farm across 3,500 acres at and near Duane Arnold in Palo, Linn County. NextEra also intends to include up to 60 megawatts of AC-coupled batteries for power storage.

The project is expected to bring in a $700 million project investment, $41.6 million in tax revenue, and around 300 construction jobs.

NextEra will negotiate leases with landowners in summer 2021 and begin construction in winter 2022. The company intends to have the solar farm online by the end of 2023.

NextEra Energy Resources currently has ownership interests in 3,160 megawatts of operating solar projects representing universal-scale solar facilities in 27 US states and one in Spain, as well as multiple small-scale (distributed generation) solar projects.

Nuclear decommissioning process

The Gazette in Cedar Rapids reports on the history of the Duane Arnold site and why the nuclear power plant was shut down

In a 2019 article, a Duane Arnold plant director told the Gazette that the facility, which employed nearly 600 people, no longer fit in Iowa’s energy portfolio that increasingly consisted of wind and solar.

The facility — Iowa’s only nuclear power plant, which began operating 45 years ago — was supposed to be decommissioned at the end of October 2020.

But “extensive” damage to the facility from the August 10, 2020, derecho [a severe storm] forced NextEra to shut it down early.

The Sierra Club explains Duane Arnold’s nuclear plant decommissioning process here, but the bottom line is that it’s going to take 60 years (and nuclear waste is of course radioactive for thousands of years):

After 60 years, the plant will be torn down, the nuclear materials would be transported to a central storage facility if one is built by then, any contamination would be cleaned up, and the land will be available for re-use.

Wind is currently the largest single source of electricity in Iowa, making up more than 40% of the state’s electricity.

Green energy sources are not to blame for the winter storm power blackouts in Texas.

Green energy sources are not to blame for the winter storm Uri power
blackouts in Texas, experts say. More than 4.2 million people were left
without power after a rare cold front brought record-breaking freezing
conditions to the state. Fox News host Tucker Carlson, among others, has
tried to point the finger at renewable energy sources such as wind turbines
for the rolling blackouts seen in the state.

Solar sails for space voyages

Nuclear Rockets to Mars?, BY KARL GROSSMAN– CounterPunch, 16 Feb 21,”………. As for rocket propulsion in the vacuum of space, it doesn’t take much conventional chemical propulsion to move a spacecraft—and fast.

And there was a comprehensive story in New Scientist magazine this past October on “The new age of sail,” as it was headlined. The subhead: “We are on the cusp of a new type of space travel that can take us to places no rocket could ever visit.”

The article began by relating 17th Century astronomer Johanne Kepler observing comets and seeing “that their tails always pointed away from the sun, no matter which direction they were traveling. To Kepler, it meant only one thing: the comet tails were being blown from the sun.”

Indeed, “the sun produces a wind in space” and “it can be harnessed,” said the piece. “First, there are particles of light streaming from the sun constantly, each carrying a tiny bit of momentum. Second, there is a flow of charged particles, mostly protons and electrons, also moving outwards from the sun. We call the charged particles the solar wind, but both streams are blowing a gale”—that’s in the vacuum of space.

Japan launched its Ikaros spacecraft in 2010—sailing in space using the energy from the sun. The LightSail 2 mission of The Planetary Society was launched in 2019—and it’s still up in space, flying with the sun’s energy.

New systems using solar power are being developed – past the current use of thin-film such as Mylar for solar sails.

The New Scientist article spoke of scientists “who want to use these new techniques to set a course for worlds currently far beyond our reach—namely the planets orbiting our nearest star, Alpha Centauri.”……. more https://www.counterpunch.org/2021/02/16/nuclear-rockets-to-mars/

Why nuclear power is a bad way to balance renewable energy  


Why nuclear power is a bad way to balance renewable energy  
https://100percentrenewableuk.org/why-nuclear-power-is-a-bad-way-to-balance-renewable-energy
David Toke, Ian Fairlie and Herbert Eppel from 100percentrenewableuk discuss how nuclear power effectively switches off wind and solar power and how a 100percent renewable energy system is much better for the UK than one involving nuclear power

The Government, backed by a lot of public policy reports paid for by pro-nuclear interests, constantly pushes out the view that nuclear power is ‘essential’ to balancing wind and solar power.

But what they never mention is the massive waste of renewables that occurs in such a scenario.

Under the scenarios planned by the Government nuclear power is paid very high prices to generate power even when there is excess electricity, which pushes renewables to close down.

The Government also refuses to undertake serious investigations of how a system that uses excess renewables to create short and long term storage is a much better way of organising our energy needs rather than wasting more money on building nuclear power statitons.

Hydrogen from wind and solar systems could be the ultimate solution to the planet’s pollution problem.

Hydrogen is turning into the next media star after solar and wind. In its
latest claim to fame, two spinoffs of German tech conglomerate Siemens are
joining forces to advance green hydrogen technology by building
wind-to-hydrogen systems to help decarbonize the global economy.
Green hydrogen is touted as a solution to many climate change problems: the
element can be an energy carrier, it can be used to store energy and it can
be used in fuel cells to power vehicles. Green hydrogen is a particularly
attractive option because its production comes from hydrolyzing water using
electricity produced by renewable systems, meaning it has a much lower
carbon footprint than gas- or coal-sourced hydrogen.
Siemens Gamesa and Siemens Energy have therefore joined a growing group of green hydrogen proponents, many of whom see it as the ultimate solution to the planet’s
pollution problem.

For the USA, despite the “Green Nuclear Deal” propaganda, solar power islooking a whole lot better.

Nuclear vs Solar: The Race For Renewable Dominance , Oil Price By Alex Kimani – Nov 11, 2020

“……….. the main sticking point to the promotion of thorium as a cleaner nuclear fuel is that it remains unproven on a commercial scale. Thorium MSRs (Molten Salt Reactors) have been in development since the 1960s by the United States, China, Russia, and France, yet nothing much ever came of them. Further, only about 50 of the world’s 440 reactors can currently be configured to run on thorium.

…… Unfortunately, practical nuclear fusion remains a long-shot and could be decades away from becoming a commercial reality.

We simply don’t have the luxury of time.

Further, nuclear power in the U.S. faces an uncertain future. ……………

Solar rising

Whereas the nuclear sector comeback has its work cut out for it, solar power has clearly been on the ascendancy thanks in large part to falling costs.

Nuclear advocates have pointed to rising electricity costs in California as the reason why other states should think twice before adopting its model. Environmental Progress has reported that between 2011 and 2018, power costs in the Golden State increased by 27.9% compared to a 4% national average. This period coincided with a period when California has been aggressively ramping up its renewable generation capacity. Renewable sources currently account for ~30% of California’s electricity generation with an aim to double that by 2030 and hit 100% by 2045.

But that’s being a bit disingenuous because it fails to capture just how much solar costs have fallen over the timeframe.

According to the Solar Energy Industries Association (SEIA), solar installation costs have dropped by more than 70% over the past decade, opening up vast new markets and systems nationwide. The organization says prices as of Q2 2020 dropped to their lowest levels in history across all market segments, with utility-scale prices ranging from $16/MWh – $35/MWh, thus making it competitive with all other forms of generation. Meanwhile, costs for the average-sized residential system were cut in half from a pre-incentive price of $40,000 in 2010 to roughly $20,000 today.

And no, renewables are not to blame for California’s blackouts.

……………..Strongly Bullish 

Despite these challenges, the solar sector remains strongly bullish.

Indeed, S&P Platts says that the shift to renewable energy is likely to continue full steam ahead regardless of fed policies noting that the energy transition has “clearly been moving forward on a regional basis,” despite lacking clear endorsement at the federal level under Trump.

It remains to be seen whether nuclear energy can command the same level of support.  https://oilprice.com/Alternative-Energy/Nuclear-Power/Nuclear-vs-Solar-The-Race-For-Renewable-Dominance.html

The global energy revolution

RethinkX 25th Nov 2020, We are on the cusp of the fastest, deepest, most profound disruption of the energy sector in over a century. Like most disruptions, this one is being driven by the convergence of several key technologies whose costs and capabilities have been improving on consistent and predictable trajectories – namely, solar photovoltaic power, wind power, and lithium-ion battery energy storage.

Our analysis shows that 100% clean electricity from the combination of solar, wind, and batteries (SWB) is both physically possible and economically affordable across the entire continental United States as well as the overwhelming majority of other populated regions of the world by 2030.

Adoption of SWB is growing exponentially worldwide and disruption is now inevitable because by 2030 they will offer the cheapest electricity option for most regions. Coal, gas, and nuclear power assets will become stranded during the 2020s, and no new investment in these technologies is rational from this point forward.

Cheap and effective, but solar energy is omitted from UK govt’s 10 point plan

Energyst 19th Nov 2020, Despite being the most cost-effective electricity generating technology for
the foreseeable future according to the Government’s own forecasts, solar
was noticeably absent from the Prime Minister’s announcement, which is
largely a repackaging of policies already announced earlier this year.

While the Government has yet to make its ambitions for UK solar clear there
is lively activity taking place in other parts of the public sector. The
City of London has announced a new 15-year Power Purchase Agreement (PPA)
with developer Voltalia, which will see a 50MW solar park built in Dorset
to supply the City with clean power. STA chief executive Chris Hewett said,

“It is disappointing that Number 10 has yet to grasp the opportunity
presented by solar in the UK. Not only is it set to be the cheapest power
source for years to come, it also provides good jobs and business
opportunities up and down the country.

Super power: Here’s how to get to 100pct wind, solar and storage by 2030 — RenewEconomy

Deep disruption: New report from futurist Tony Seba and RethinkX says transition to 100pct renewables possible by 2030, and the “super” surplus of wind and solar can be used to power transport and industry. The post Super power: Here’s how to get to 100pct wind, solar and storage by 2030 appeared first on RenewEconomy.

Super power: Here’s how to get to 100pct wind, solar and storage by 2030 — RenewEconomy
A team led by renowned Stanford University futurist Tony Seba says most of
the world can transition to 100 per cent wind, solar and storage
electricity grids within the coming decade, in what they describe as the
fastest, deepest and most profound disruptions ever seen in the energy
industry.
The RethinkX team led by Seba, one of the few analysts to
correctly forecast the plunging cost of solar over the last decade,
predicts that the disruption caused solar, wind and lithium-ion battery
storage, or SWB, will be similar to the digital disruption of information
technology. “Just as computers and the Internet slashed the marginal cost
of information and opened the door to hundreds of new business models that
collectively have had a transformative impact upon the global economy, so
too will SWB slash the marginal cost of electricity and create a plethora
of opportunities for innovation and entrepreneurship.”
“Our analysis
shows that 100% clean electricity from the combination of solar, wind, and
batteries (SWB) is both physically possible and economically affordable
across the entire continental United States as well as the overwhelming
majority of other populated regions of the world by 2030.
“Adoption of
SWB is growing exponentially worldwide and disruption is now inevitable
because by 2030 they will offer the cheapest electricity option for most
regions. Coal, gas, and nuclear power assets will become stranded during
the 2020s, and no new investment in these technologies is rational from
this point forward.”
The analysis from Seba and the RethinkX team is just
the latest of a series of important reports that have been released in
recent weeks and months that look at the pace of technology change, the
energy transition and climate goals.
