‘Spinning’O-Wind Turbine captures wind from any direction
O-Wind Turbine: James Dyson Award National UK Winner
The O-Wind Turbine captures wind from any direction and, unlike traditional turbines, could be effective in cities A ‘spinning’ turbine which can capture wind travelling in any direction and could transform how consumers generate electricity has won its two student designers a prestigious James Dyson award.
Nicolas Orellana, 36, and Yaseen Noorani, 24, both MSc students at Lancaster University, have created the O-Wind Turbine which – in a technological first – takes advantage of both horizontal and vertical winds without requiring steering.
Conventional wind turbines only capture wind travelling in one direction, and are notoriously inefficient in cities where wind trapped between buildings becomes unpredictable, making the turbines unusable…….

Wind power currently generates just 4% of the world’s electricity but it could produce up to 40 times the amount of electricity consumed, Noorani said.
The duo’s invention will now be entered into the international running for the final leg of the James Dyson award in November, which will give the overall worldwide winner a further £30,000 in prize money.
The award operates in 27 countries, and is open to university level students and recent graduates studying product design, industrial design and engineering. It recognises and rewards imaginative design solutions to global problems with the environment in mind. https://www.theguardian.com/environment/2018/sep/05/groundbreaking-spinning-wind-turbine-wins-uk-dyson-award
Renewable energy systems set to go ahead with new technology enhancing flexibility
Chatham House 22nd Aug 2018 Electricity Markets** As renewables become a large share of the global energy mix, greater electricity system flexibility will be critical and will originate from thesmall scale, write Daniel Quiggin and Antony Froggatt.
represent 75 per cent of global renewable electricity capacity growth over
the medium-term’. Bloomberg New Energy Finance also estimates that by
2040, nearly three-quarters of the $10.2 trillion invested in new
power-generating capacity will be in renewables.
costs associated with managing the system start to escalate once renewables
exceed a 30 per cent share of generated electricity. Unless properly
planned for, the growth in electric vehicle use and electric heating could
further amplify these ‘system integration costs’. They include the cost
of holding fossil fuel power plants in reserve for periods of low renewable
supply, grid upgrades and the dumping of power from renewables when system
constraints are reached.
and as a growing number of cars and domestic-heating systems begin to add
to power usage, how can governments ensure electricity is affordable? The
answer is ‘flexibility’. A raft of technologies already entering the
market, promise to radically enhance the flexibility of electricity
systems, helping contain system integration costs while accelerating the
low-carbon transition.

Flexible localised renewable energy networks in UK
Centrica (accessed) 24th Aug 2018 , By 2040 Bloomberg New Energy Finance predicts that more than half of global
energy capacity will come from renewables and flexible sources, such as
battery storage and demand side response. At 7% of global capacity,
flexible sources such as batteries and demand side response – where homes
and businesses automatically cut energy usage a peak times – will account
for the same level of global energy capacity as oil-fired power plants
today.
And more than half of this energy storage capacity will come from
small-scale batteries installed by households and businesses alongside
rooftop solar panels.
This trend away from larger power plants and towards
smaller, decentralised energy systems is happening in both developed and
developing nations. The decarbonisation trend is being accelerated by the
falling price of renewable energy technology, and the availability of
technology such as batteries that makes it easier to store electricity.
This in turn accelerates decentralisation, as renewables are by their
nature smaller and more spread out than the equivalent capacity provided by
a traditional power plant.
The rate of decarbonisation and decentralisation
is being accelerated by digital technology, giving people the power to
save, or even make, money by being more flexible with their energy use,
while helping electricity grid operators to balance supply and demand.
Europe’s largest demand side response aggregator, REstore, was acquired
by Centrica in 2017. Centrica CEO Iain Conn says he expects demand side
response to become one of the fastest growing elements of the energy market
over the next few years. From smart home products such as Hive that allow
home owners to control their energy use from their smartphone, through to
companies like REstore employing artificial intelligence to calculate just
how much energy capacity a factory can offer as a virtual power plant.
Energy, like every other sector, is going digital.
Greater insight through
digital technology is just the start of the shift of power away from energy
companies and towards the customer. Centrica is currently piloting a
project in the south west of England that will allow local residents and
businesses to buy and sell energy between themselves without the
intervention of their energy supplier. The £19 million Local Energy Market
in Cornwall is enabling 200 homes and businesses to do this using a digital
record known as Blockchain. It is used to create a secure electronic ledger
of transactions between participants. Iain Conn says he believes such local
networks will become the norm in a new decentralised energy market.

U.S. army increasing its investment and use of solar power
FT 24th Aug 2018 The US Army has increased its investments in solar power and is eyeing
further opportunities to work with the private sector to develop projects,
despite the Trump administration’s scepticism about renewable energy.
Michael McGhee, who leads the US Army’s Office of Energy Initiatives, told
the Financial Times that installing solar panels at army bases could
improve resilience against attacks or natural disasters, and provide
cost-effective electricity supplies.

US Government’s own Energy Information Administration (EIA) says renewable energy is surging while nuclear is declining
EIA Data Undermines Trump’s Love Affair With Coal & Nuclear https://cleantechnica.com/2018/08/13/eia-data-undermines-trumps-love-affair-with-coal-nuclear/ August 13th, 2018 by Joshua S Hill
A handful of reports published over recent weeks by the US Government’s own Energy Information Administration (EIA) and the Federal Energy Regulatory Commission’s (FERC) have revealed that coal and nuclear continue their decline across the country, while renewable energy continues to surge with longevity which will quickly take it out beyond the reach of the United States’ traditional generators.
So far this month, the EIA has published its “Electric Power Monthly” report and its “Short-Term Energy Outlook” for August, while FERC published its “Energy Infrastructure Update.” When taken together, and excluding an expected decline in utility-scale solar capacity additions, it is good news for the renewable energy industry and bad news for the United States’ coal and nuclear sectors.
Specifically, the United States’ renewable energy sources — consisting of biomass, geothermal, hydropower, solar, and wind — now provide more electricity than nuclear power in over half the states across the country, and more electricity than coal in a third of the states. Further, according to data compiled from the reports by Ken Bossong of the Sun Day Campaign, over the next three years of capacity additions and retirements, the US coal industry will experience a net-loss of 15,898 megawatts (MW) and the nuclear industry will only see a net-increase of 756 MW.
Conversely, utility-scale renewable energy capacity is expected to skyrocket by 156,981 MW over the same time period, led primarily by wind energy with nearly 91 gigawatts (GW) and solar with just over 52 GW.
“EIA and FERC data underscore that the renewable energy train has left the station,” noted Ken Bossong, Executive Director of the SUN DAY Campaign. “Trying to reverse that situation with costly subsidies for environmentally-polluting nuclear power and coal defies common sense.”
“Nuclear and coal simply can’t compete with renewable energy,” said Tim Judson, Executive Director of the Nuclear Information and Resource Service. “Renewables will be generating more power than nuclear by 2020, and nuclear is poised for the same precipitous decline as coal in the coming years.”
It’s worth noting that “capacity” is not the same as “generation” — because, as Ken Bossong explains, “nuclear and coal typically have higher capacity factors than most renewable sources” — but one need only look at the figures to see that renewable energy is catching quickly here as well. Specifically, renewable energy generation over the first five months of 2018 accounted for 20.17% of the United States’ electrical generation, while nuclear only provided 20.14%. Further, while coal still maintains a healthy lead over both renewables and nuclear with 26.6% over the first five months of 2018, this is down from 39% five years ago when renewables only accounted for 14.3%.
The only substantial negative takeaway from this bundle of official US Governmental reports is that the EIA has downgraded its forecast utility-scale solar capacity additions for 2019 from 11.4 GW to 6.3 GW “As a result of incoming data reported in the Annual Electric Generator survey.” This will be combined with an estimated 3.94 GW worth of residential, commercial, and industrial solar, bringing the total 2019 expected solar capacity additions up to 10.3 GW — a 7% growth on the 9.58 GW expected to come online this year.
Taiwan’s energy transition from nuclear to wind and solar power
Nuclear Ghost Town Reveals Power Risk for Taiwan’s Energy Shift, Bloomberg, By Dan Murtaugh, Miaojung Lin, and Samson Ellis August 7, 2018,
- Plan to shut reactors sparks race to develop wind, solar power
- Goal is 70% of electricity from gas, renewable sources by 2025
A map at the guard-house of the Lungmen Nuclear Power Plant in Taiwan shows what might have been: Classrooms, dormitories, a grocery store, a police station. It was supposed to be a self-contained city on the island’s northeast coast designed to meet growing demand for electricity in Asia’s seventh-largest economy.
Instead, the complex stands empty — unfinished and never used — a $10 billion casualty of growing public opposition to nuclear power. Since a disastrous 2011 reactor meltdown in Japan, more than 1,400 miles (2,250 kilometers) away, Taiwan has rewritten its energy plans. President Tsai Ing-wen ordered all of the country’s nuclear reactors to shut by 2025.
Taiwan’s Transition
Taichung gears up for wind power as Lungmen’s reactors are mothballed
That’s set off a high-risk gamble to find alternatives to nuclear, which supplies 12 percent of the island’s electricity, while limiting an increase in carbon emissions. The island’s sprint reflects a drive across the region toward cleaner energy sources such as sunlight, wind and natural gas. Nations from Australia to South Korea and mainland Chinato India are seeking to meet rising demand without belching more emissions blamed for climate change and smog.
Taiwan’s solution: Wind turbines are planned in the blustery Taiwan Strait, solar panels are popping up on coastal salt flats, and terminals are being planned to import more liquefied natural gas. But new sources could take years to develop, making power rationing and blackouts a possibility as the gap narrows between demand and generating capacity.
“There are going to be concerns over the next few years about reserve margins and power supply reliability,” said Zhouwei Diao, an IHS Markit analyst in Beijing.
The government’s plan has several parts. First, all nuclear and most oil-fueled generators will be shut. Together, they supplied 16 percent of Taiwan’s electricity in 2016. The country will still have about the same amount of coal capacity by 2025 as now, but its share of total power generation will drop to 30 percent from about half as sources of alternative energy expand. Natural gas will see the biggest usage gain, accounting for half of supply by 2025, while renewables like wind and solar will more than triple to 20 percent.
As electricity demand grows over the next seven years, the government says it will boost generating capacity while limiting carbon emissions and ridding itself of a political headache.
Taiwan’s state-run nuclear industry already was unpopular after it built a controversial waste-storage site on Orchid Island, home to one of the country’s indigenous peoples. But sentiment turned even more negative after the disaster in Japan, which occurred after a giant earthquake and tsunami. The disaster prompted countries including Germany and South Korea to ditch their nuclear programs.
Taiwan Power Co. operates three nuclear plants and was building the fourth in Lungmen when the Fukushima meltdown occurred. In 2014, the government halted construction that was nearly complete, with uranium-fuel rods in place. In 2016, the Democratic Progressive Party won election on an anti-nuclear platform. Last month, workers removed the unused fuel rods and sold them to a buyer in the U.S.
…….. The government has held firm to its plan. Part of the optimism comes from the plunging cost of building wind and solar projects around the world. There’s also expanding supplies of cheap liquefied natural gas available from the Middle East, Australia and the U.S…….. https://www.bloomberg.com/news/articles/2018-08-05/nuclear-ghost-town-reveals-power-risk-for-taiwan-s-energy-shift
Renewables produced more electricity than nuclear for the first five months of 2018
US Renewables Are Closing In on Nuclear Generation, GT, Renewables produced more electricity than nuclear for the first five months of 2018. AUGUST 09, 2018
“..After decades of stalled nuclear plant development and the recent surge of increasingly cheap wind and solar deployments, the newcomers are pulling ahead. In the first five months of 2018, renewables produced 20.17 percent of U.S. electricity and nuclear produced 20.14 percent, according to Energy Information Administration data compiled by Ken Bossong of the Sun Day Campaign.
A similar record was hit in the first three months of 2017.
In the two most recent months included in the data set, April and May, renewables outproduced nuclear by more than 10 percent. …… Renewables out-generate nuclear in more than half of states, according to an analysis of EIA data by the Sun Day Campaign.
Sun Day has a very clear stake in this race: Its mission is to promote sustainable energy and help “phase out the use of nuclear power.”..
Optimistic report on Swansea Bay Tidal Lagoon- tidal renewable energy for Britain?
Wales Online 26th July 2018 , A new task force is being set up to look at ways of resurrecting plans for
the Swansea Bay Tidal Lagoon, which appeared dead in the water just last
month. It follows the publication of a report which said the £1.3bn
project could be delivered without the need for a UK Government financing
deal. The report concluded that the lagoon was “fundamentally a strong
and deliverable technical proposition”.Paul Marsh, of report authors
Holistic Capital, said: “We believe the project can be funded
independently of UK Government, and potentially delivered as a purely Welsh
initiative. “We believe, based on our in-depth review, that the original
£1.3bn cost of the lagoon can be reduced.

Renewable energy headed to be 50% of total UK electricity generation by 2025.
Dave Toke’s Blog 26th July 2018 Today’s UK energy statistics reveal that renewable electricity generation
increased by around 20 per cent in just one year so that 29.3 per cent of electricity consumed came from renewable energy in 2017.
If at least 80 per cent of the offshore windfarms now in different stages of planning (let alone other renewable energy sources) come online, as could be expected, in the next 7 years, then renewable energy will comprise half of total UK electricity generation by 2025.
Electricity consumption fell once again in the year 2017 compared to 2016. Electricity consumption is now 9 per cent less than it was in 2010. over 20 GWe of offshore wind are in various stages of planning and construction. In total these would generate around 25 per cent of UK electricity.
Since the Government are saying they will hold auctions for offshore wind and some other renewables in 2019 and 2021
this means that a lot of them will be built by 2025. Of course we are going to have substantially more onshore wind and solar by 2025 to buttress these figures (although the Government are doing very little to help) meaning that electricity generated from renewable energy will top 50 per cent of total consumption in 2025/6

Japan’s biggest utility, Tokyo Electric Power Company moving from nuclear power to renewables
Japan’s Tepco plans 7GW renewables roll-out, in pivot away from nuclear, REneweconomy, By Sophie Vorrath on 26 July 2018
Japan’s biggest utility, Tokyo Electric Power Company, has revealed plans to develop up to 7GW of new renewable energy capacity, marking a major departure from nuclear as the company strives to re-gain “the competitive advantage” in energy generation.
Tepco President Tomoaki Kobayakawa told the Nikkei Asian Review on Monday that the company planned to pour tens of billions of dollars into between 6 and 7GW of renewable energy projects both in Japan and abroad, including offshore wind and hydro power.
Reports suggest the focus in Japan will largely be on offshore wind, including the use of floating turbine technology that is considered to be well suited to the island nation’s relatively deep coastal waters.
And in hydro, Tepco plans to develop sites in south-east Asia, alongside its overseas and domestic wind power businesses. The company reportedly hopes to have each of the three renewables components generating at least 2GW of power.
……..The new tack for Tepco suggests a major change in direction and thinking in the Japanese electricity market, where a skew towards nuclear and “baseload” generation has roughly mirrored Australia’s attachment to coal.
As a 2016 Greenpeace Japan report noted, the nation’s nuclear utilities have had a history of “(lobbying) hard for the right to block access to the grid for renewable power plants” whenever they deemed it necessary to preserve grid stability.
They argued, said Greenpeace Japan, the all-too familiar line that the fluctuating output of renewables was incompatible with the output of nuclear reactors the government was trying to restart.
But this thinking appears to be shifting, and not just among power companies. A separate report last week in the Nikkei Asian Review noted that renewable energy momentum was also building in Japan’s corporate and industrial sectors, boosted by the liberalisation of the nation’s energy market in 2016.
“More Japanese companies are promising to source all of their electricity from renewable energy in 10 to 30 years,” the news site said. “A trend that could in turn spur investment to bolster grid capacity, to accommodate demand.” https://reneweconomy.com.au/japans-tepco-plans-7gw-renewables-roll-out-in-pivot-away-from-nuclear-72286/

China General Nuclear Power Corporation (CGN) acquires 75% stake in Swedish wind power project
Reuters 18th July 2018 , China General Nuclear Power Corporation (CGN) has acquired a 75 percent
stake in a Swedish wind power project from Australia’s Macquarie Group
and GE Energy Financial Services, state news agency Xinhua reported on
Wednesday. The North Pole wind power project, located in Pitea, Sweden, is
expected to be operational by the end of 2019 with a capacity of 650,000
kilowatts, making it the single largest onshore wind power park in Europe,
Xinhua said.

66% of UK voters support onshore wind power
Independent 16th July 2018 , Two-thirds of British people think the government should ditch the policies
that have all but killed off the UK’s onshore wind industry, according to a
new poll.
Since new rules governing the construction of onshore turbines
were introduced following the election in 2015, planning applications for
new wind farms have plummeted by 94 per cent. As the government struggles
to meet strict greenhouse gas emissions targets, experts have criticised
the effective ban on technology that is widely considered the UK’s cheapest
new power source.
Aside from the environmental and industry arguments for
promoting onshore wind, the technology has considerable support from the
British public, as the government’s own data on public attitudes to
renewable energy have shown. Now, a new opinion poll by YouGov has revealed
66 per cent of voters would support a change in policy that allowed onshore
wind farms to be built in places where they have local backing. Current
policies were initially introduced following a Conservative promise to
“halt the spread of onshore wind farms” which “often fail to gain public
support”.

UK’s academic and government experts now agree that renewable energy, not nuclear power, is Britain’s future
Telegraph 15th July 2018 , Support for renewable energy is no longer the preserve of eco-warriors, nor
the enemy of the sceptical pragmatist. Experts from academia and government
agree that after years of heavy subsidy, renewable energy is close to
paying its own way.
“Few would have imagined that by 2018 we would be
talking about a subsidy-free future for renewables,” admits Mateusz Wronski
of Aurora Energy Research. “Yet this is where we have arrived – and our
research highlights clearly the enormous prize and potential in the market,
not only in Great Britain but across Europe.”
Aurora broke ranks with traditional energy rhetoric earlier this year by publishing data showing
that new renewable energy projects are now the cheapest source of
electricity in the market and hold the promise of a multi-billion-pound
investment boom for Britain. “The subsidy-free revolution is here, and it’s
big. This is a £60bn investment opportunity in north-west Europe alone,”
Wronski says, with Britain poised to gain far more than any other country
from the coming revolution.
A rapid shift in the economics of energy has
brought renewables to the brink of a major tipping point only a few years
away. Britain could begin to host onshore wind and solar projects without
the need for subsidies from the early 2020s, to unlock about £20bn of
investment between now and 2030. At the end of the next decade, offshore
wind will follow suit.
Last week, the renewable agenda found a fresh ally.
Sir John Armitt, the chairman of the National Infrastructure Commission,
made the most hard-headed case for renewable energy yet. In the first ever
independent assessment of Britain’s infrastructure needs, the commission
dealt a blow to the Government’s nuclear ambitions by warning ministers
against striking a deal for more than one follow-up to the Hinkley Point C
project before 2025.
Instead, government should focus its efforts on
rolling out more renewable power. The pace of the zero-subsidy roll-out
could become quicker if developers are allowed to enter their “zero” bids
into the flurry of auctions held by National Grid throughout the year to
guarantee generation and an optimal frequency for the grid. By taking part
in the subsidy auctions, wind developers would soon be able to cast a bid
at or below the cost of wholesale power prices, which would effectively
mean zero added costs to bills. This would provide certainty to investors,
lower the project’s risk and reduce the cost of capital needed to bring the
projects to life. In turn, consumers would be in line for lower bills.
