Here at Green ISP we have been making folk aware of the innovative and de-centralizing elements of money transactions and the “BlockChan” via Bitcoin and other Crypto currencies such as Etherium etc…

One BIG Issue that is starting to become mainstream in the wake of the popularity of bitcoin (especially for speculation purposes) is the vast amount of Energy required to complete a single transaction and the massive energy requirements to mine a coin, or part of a coin.

We locate some of our Hosting services in a datacentre in Icelend as it is 100% renewable and to take advantage of free cooling, however when it comes to others using iceland to mine Bitcoin it’s a different story?  “This year, electricity use at Bitcoin mining data centres is likely to exceed that of all Iceland’s homes”, according to Johann Snorri Sigurbergsson, spokesman for Icelandic energy firm HS Orka.

The crypto-currency mining industry in Iceland was recently given a boost thanks to the launch of The Moonlite Project – a large data centre where various crypto-currencies, including Bitcoin, will be mined.

It is set to open later this year and will have an initial capacity of 15 megawatts, though this is expected to increase in the future.

It’s certain that the increasing energy burden of bitcoin transactions will divert progress from electrifying the world and reducing global carbon emissions. In fact, I’d guess it probably already has. The only question at this point is: by how much?

I believe that the rise in popularity of Bitcoin as a way of making money without taking into account the environmental impact could be a risky path, especially if we loose sight of what the Blockchain can offer with Bitcoin bolted on as a tool rather than a speculative means to no end?

Sounds very familiar to me (current monetary system out of whack with an resources based economics)…

Food for thought?

Food Waste Update http://www.greenisp.net/blog/food-waste-update http://www.greenisp.net/blog/food-waste-update#respond Sun, 30 Apr 2017 10:08:33 +0000 http://www.greenisp.net/blog/?p=551 Hi there again, sorry its been a long time, lots going on at the moment.

Here is another recent news item that we talked about several years ago.


Committee chairman Neil Parish said: “One-third of food produced for human consumption is lost or wasted globally, and in the UK over £10bn worth of food is thrown away by households every year.

http://www.bbc.com/news/science-environment-39747327

As we have said before here at Green ISP food waste is a real problem, the big Pharma and the likes of Monsanto would like us the think theres a massive food shortage, of course they do, because they can then sell GMO one year switch off seeds and the Pesticides and herbicides that are proving to be so hazardous to other life systems.

Good reading.

Portugal runs solely on renewable energy for four days straight. http://www.greenisp.net/blog/portugal-runs-solely-on-renewable-energy-for-four-days-straight Fri, 20 May 2016 13:58:30 +0000 http://www.greenisp.net/blog/?p=534 Hello there again.

What a turnaround, only 15 years ago the UK and Portugal were seen as 2 of the the Dirty Countries of Europe, we sent Acid Rain to Scandinavia in the 70’s and 80’s too, because we in the EU we had to do something about that too.

It seems Portugal is taking the idea of Cleaner, more sustainable and renewable enengy production very seriously indeed, AND in a So Called time of Austerity and Hardship…

You would think, that if the UK for example was (as the current Government put it themselves) Quote… “the Greenest Government Ever” and also while we boast of the size and power of our economy, needing a referendum on membership to the EU, that we could show Jonny Foreigner a thing a too about the matter.

PV_Portugal

Last year in Portugal, wind provided 22% of electricity and all renewable sources together provided 48%, and in part has been spurred by the EU’s renewable targets for 2020.

Only Austria, Latvia, Finland and Sweden are expected to have a higher share by 2020, while the UK, comparatively, the UK total is floating at a total of about 20%, which is a great improvement on how low it was 15 years ago, still, with a potential of 100% renewables due to all the wind, wave and hydro etc, we should in fact be the EU Leader?? i wonder why not?

Anyway.

Have a read of these two articles linked below.

Thanks.

Is Canada’s Great Bear Rainforest Saved? Looks like it…. http://www.greenisp.net/blog/is-canadas-great-bear-rainforest-saved-looks-like-it Tue, 02 Feb 2016 13:13:19 +0000 http://www.greenisp.net/blog/?p=528 Indigenous tribes, logging firms and environmental groups in Canada have struck a deal to protect one of the world’s largest tracts of temperate Rainforest.

The Great Bear Rainforest on the Pacific coast of British Columbia is home to many animals and ancient trees.

Importantly, Logging will be banned across a huge area of the forest.

Environmental campaigners say it is a model for resolving similar land-use disputes around the world.

The forest is inhabited by the spirit bear, a rare sub-species of the black bear with white fur, and is also home to 26 aboriginal groups, known as First Nations.

Its enormous habitat covers 32,000 sq km (12,000 sq miles) on the Pacific coast of Canada, helping purify both air and water, and is an unspoiled home to grizzly bears, wolves and cougars.

canadaforest

Let us hope this deal paves the way to Stop any future plans for oil or gas exploration or any pipelines throgh the region?

“Our leaders understand our wellbeing is connected to the wellbeing of our lands and waters,” said Chief Marilyn Slett, president of Coastal First Nations.

“If we use our knowledge and our wisdom to look after our lands and waters and communities, they will look after us into the future.”

The announcement comes nearly two years after a landmark Supreme Court decision that granted title to a vast swath of British Columbia’s interior to the Tsilhqot’in First Nations, who had gone to court to stop logging in their traditional lands.

That decision has bolstered First Nations across the province, who now have a legal precedent for fighting development on their territories.

Carbon Nano-Tubes out of Thin Air….. http://www.greenisp.net/blog/carbon-nano-tubes-out-of-thin-air Thu, 20 Aug 2015 09:31:11 +0000 http://www.greenisp.net/blog/?p=520 Hi there.

If you follow Green ISP News Blog you may remember the post made back at the end of 2013: http://www.greenisp.net/blog/?p=451

Interesting demonstration about Carbon nano technology, specifically Carbon Nano-Tubes for use in Electrical power and lighting solutions etc.

Well…. there is a further Development here, as we are all aware, there’s the issue of CO2 and climate change linked to it, all that extra carbon dioxide clogging our atmosphere might be useful for something here. Using a new development and process to extract Carbon from the atmosphere and produce Carbon composites and nano tech??? so far sounds great to me…

In a process described at this week’s American Chemical Society meeting in Boston, Massachusetts, the carbon from piped-in air was spun into tiny nanofibres – a raw material used to build strong composites such as those used in aircraft and cars etc.

A team led by Stuart Licht, of George Washington University in Washington DC, has designed a process that actively strips carbon from the air and turns it into a product that Licht claims can be sold for much more than the cost to produce it.

nano_structure

The electric current used to power this process could come from conventional sources – which might offset the technique’s carbon-sucking potency – but Licht has also successfully run it on solar power.

So, Add on the Idea or Carbon Nano Tube tech producing the actual Electricity to run these things and the mind boggles what could be done here, think about it???

 

 

Anyway, here’s some links and a link to the article:

Tesla Motors has unveiled batteries that power homes http://www.greenisp.net/blog/tesla-motors-has-unveiled-batteries-that-power-homes Fri, 01 May 2015 10:32:31 +0000 http://www.greenisp.net/blog/?p=512 US electric car maker Tesla Motors has unveiled batteries that power homes and businesses as it attempts to expand beyond its electric vehicle ventures.

CEO Elon Musk announced the firm will build batteries that store solar energy and serve as a back-up system for consumers during blackouts, jsut as standard lead acid solar batteries have done for years.

The device/s will allow consumers to get off a power grid or bring energy to remote areas that are not on a grid, connect to each-other over the internet to create Local Smart Grid systems, first shipping to Germany outside the US in 2016.

“Our goal is to fundamentally change the way the world uses energy,” Musk told a press conference at the Tesla Design Center on Thursday night. “It sounds crazy, but we want to change the entire energy infrastructure of the world to zero carbon.”

A great vision, however, as positive as this is I just wonder where all the rare earth metals etc are going to come from???

Supercapacitors made from Hemp “on a par with or better than graphene” http://www.greenisp.net/blog/supercapacitors-made-from-hemp-on-a-par-with-or-better-than-graphene Wed, 13 Aug 2014 12:56:01 +0000 http://www.greenisp.net/blog/?p=499 Hi there.

For anyone reading the post earlier in 2014 (link below).

Renewables Boost?  “flow battery technology”.
http://www.greenisp.net/blog/?p=491

This will be of interest to you too.

Graphene is quite an amazing product and is being touted as a new superconductor as well as many other uses, well, we used to think of Hemp as a useful and economic material only a few decedes ago, from hard resins for cars to rope for ships, may it’s time have come again 21st century hi tech?

The waste fibres from hemp crops can be transformed into high-performance energy storage devices, scientists say.
They “cooked” cannabis bark into carbon nanosheets and built supercapacitors “on a par with or better than Graphene” – the industry gold standard. Electric cars and power tools could harness this hemp technology, the US researchers say.

hemp
This is what David Mitlin of the American chemical society told NBC News this week.

“Industrial hemp, the non-psychoactive cousin of marijuana, can play a role in manufacturing super-powerful supercapacitors for energy storage at a cost that’s far cheaper than graphene, researchers report.
The hemp-based technology took center stage Tuesday at the American Chemical Society’s national meeting in San Francisco.
A team led by David Mitlin, an engineering professor at Clarkson University, heated up hemp fibers to create carbon nanosheets that can be used as electrodes for supercapacitors.
Compared with graphene, the hemp-derived carbon is “a little bit better, but it’s 1,000 times cheaper,” Mitlin told NBC News.

So, the renewable energy sector may have the answer to all it’s storage issues in future, cost effective and totally carbon neutral and environmentally friendly.?

Not to undermine the incredible properties of Graphine and the amazing work done by the Manchester UK team, but it may be the Graphine / Hemp link could be ground-breaking stuff?
