Another example of what can be done by shifting the subsidies between different forms of power generation:


Japan's renewable revolution at risk

Could Japan survive without nuclear power? The short answer to that question is yes.

Japan has been surviving surprisingly well without nuclear power for the last four years... But there has been a cost. Prior to the Fukushima disaster nearly 30% of power came from nuclear. That has been replaced by burning lots more coal and gas...

But in the four years since the nuclear plants were shut down, Japan has also begun to witness something else - a renewable energy revolution. And the return to nuclear power may be putting that under threat.

Japan is a mountainous island nation with a sunny climate and lots of active volcanoes. In other words there are lots of potential ways to generate renewable energy - hydro, wind, tidal, solar and, the big one, geothermal...




There is a very large investment in the nuclear plant so there is some sense there to make use of what has already been invested...

There is also the very unfortunate parallel for the ridiculous exploration costs invested in searching and exploiting for yet more oil to burn when our environment cannot afford the pollution from burning what we are burning already! Yet Dirty Oil will exclaim that they just must recover their already invested investment...


There are better ways. So how to overcome the corruption of those clinging to profit from the old dirty ways and our planet be damned?...

Geothermal power is considered to be a sustainable, renewable source of energy because the heat extraction is small compared with the Earth's heat content.[4] The greenhouse gas emissions of geothermal electric stations are on average 45 grams of carbon dioxide per kilowatt-hour of electricity, or less than 5 percent of that of conventional coal-fired plants.

We can also make much better use of the power we already use. Amazing this hasn't been made use of sooner:


Heating houses with 'nerd power'

All computers produce heat, but computer servers produce a lot of heat - so much that it usually costs a fortune to cool them down. So why isn't this heat used instead to keep homes or offices warm? Actually, "nerd power" is already being tried out...

... If Facebook had built their centre close to a city, they would have paid more for the land, but Karlung says that would have been more than compensated for by [heat] energy sales. "Nobody had the idea," he says, adding mischievously: "Every time you log into Facebook, you kill a polar bear."...

... Since getting his Nerdalize radiator, Jerry van Waardhuizen has become more aware of the issue of heat retention. "In my company we have some servers," he says. "We put on an air con above it - we give a lot of money to destroy the heat. That's crazy! That's crazy! Everybody is doing that."...



Crazy wasteful indeed, and largely needless, all just for the sake of a little thought and care for following a longer term plan...

Facebook plans to build a new data center at its server farm in northern Sweden.
http://www.bloomberg.com/bw/articles/2013-10-03/facebooks-new-data-center-in-sweden-puts-the-heat-on-hardware-makers
The location has a lot to do with the system’s efficiency. Sweden has a vast supply of cheap, reliable power produced by its network of hydroelectric dams. Just as important, Facebook has engineered its data center to turn the frigid Swedish climate to its advantage. Instead of relying on enormous air-conditioning units and power systems to cool its tens of thousands of computers, Facebook allows the outside air to enter the building and wash over its servers, after the building’s filters clean it and misters adjust its humidity. Unlike a conventional, warehouse-style server farm, the whole structure functions as one big device.

https://www.facebook.com/LuleaDataCenter

250,000 people pass every day through Stockholm Central Station, and all these people give off heat when they go between different platforms, or stop and shop. Previously this heat used to be sent right out through the ventilation system, to no avail, but by instead taking advantage of the energy and send it to an office complex near the building reduced its energy costs by 25%.

I know that Ukraine has a LOT of energy efficiency problems that needs to be fixed...

The Internet is an energy consumer, not an economic growth rescuers. And that the absolute majority of the electricity generated in the world comes from fossil fuels, the Internet Usage is not sustainable globally.

(snip)

The university does something a bit like that.

The physics building has the university's substation adjoining the end of it. This substation produces quite a lot of heat and has fans to cool it. On hot days, the fans suck in air from the sides and blow it out the front. On cold days, the side flaps close, the rear flaps open, and the fans reverse to suck in air from the front and blow it into the building's ventilation system. It doesn't quite provide all the building's heat requirements, but is certainly a sizable chunk of it.
Life on earth is the global equivalent of not storing things in the fridge.

All of this is routinely done by large corporations. The latent heat given off by individuals is often more than enough to heat a large office building.

When I worked for Bell Labs in their famous "Puzzle Palace" at Holmdel New Jersey the building had 3500 people and dozens of labs with plenty of equipment. There was a Monday morning warm up but other than that the building had to be cooled even in winter. There were two enormous ponds out front that were the heat exchangers. Plastic Swans were floating in the ponds to keep the Canada Geese from fouling the ponds.

There was a long drive that led between the middle of the ponds. You could accelerate to 100 MPH and then brake for the sharp turn to keep you from going into the pond--this was to gain membership into the 100 MPH club. My 1979 Pontiac Grand Prix could do it easily.

Years before when i managed large IBM mainframes that required water cooling, we had a Glycol system that used outside air for cooling when the temperature got below 45 degrees F. That building had steam absorption air conditioning that was driven by the waste heat from our Campus power plant. Co-generation produced nearly BTU per BTU efficiency. The air conditioning itself ran at 300% efficiency (three times the cooling power per watt of input.

The University of Illinois had probably the world's largest steam absorption-air conditioning system in the world in our 170 buildings in Champaign/Urbana Illinois. I managed the enery budget of 30 million dollars which threatened to eat up all of our new funds during the Jimmy Carter years of irresponsible government.

Interesting example thanks.

Errr... Is that called the High Energy Physics building? With added sparks? ;-)


More seriously...

I tried to get heat recycling included in a new server room build. Unfortunately, the quality of the builders was just not up to adding any 'extras' onto the job... All they could do was bolt on their standard repertoire of standard units. No thought possible.

And so all the server room heat gets expensively thrown out of cooling radiators and big fans at the back of the building :-(


Also unfortunately, the plant 'manager' is rather averse to any 'extra work' and so has no interest in adding a heat exchanger into the loop to pre-heat the building air. (He's uninterested enough about the CHP gas engine that generates some of the server room power...)


How do you get people enthused about something they simply do not care about?...

All on our only one planet,
Martin


Aside:

The builders were incredible... Either that or were on a game to make extra work for themselves... Despite completely clear architect plans/drawings, they fitted the server room door right on to the end of a row of server racks. Even better, there was only a few cm of clearance even if the door could be opened! Myself and the architect then had a crazy discussion with the builder about the measurements and... Even thought the room dimensions were built wrong, we agreed they moved the door and changed it to open outwards, and that one wall was moved to at least give "beer-belly" room at the end of the racks to get past them. The architect had the biggest belly which set the clearance.

I've now got scrapes along the walls and racks from one of the builders crew who sported an enormous Guinness belly plus tool belt...

No wonder UK buildings are so badly inefficient and costly!

How do we fix that?...

Thermodynamics comes to mind:)
http://en.wikipedia.org/wiki/Enthalpy
I was at a alumininum Company called SAPA when i studied at KTH Polytech on a field trip.
There lots of heat that get waisted in the process.
Someone asked if that energy could be reused.
The Company said that it is a very low enthalpy and therefore meaningless.
Well. Today we have the technology to use energy Resources with low enthalpy.

A little something long overdue?...


Global Apollo programme seeks to make clean energy cheaper than coal

... The Global Apollo Programme aims to make the cost of clean electricity lower than that from coal-fired power stations across the world within 10 years. It calls for £15bn a year of spending on research, development and demonstration of green energy and energy storage, the same funding in today’s money that the US Apollo programme spent in putting astronauts on the moon.

The plan is the brainchild of a group of eminent UK scientists, economists and businessmen including Sir David King, currently the UK’s climate change envoy, Lord Nicholas Stern, Lord Adair Turner and ex-BP chief Lord John Browne.

King said green energy already had advantages over fossil fuel power in cutting deadly air pollution and reducing the carbon emissions that drive global warming. But he said making clean energy cheaper was important too: “Once we get to that point, we are winning in all the battles.”...

... electricity from coal-fired power stations only appeared cheaper because the costs of air pollution and climate change were not included. He noted that the IMF recently calculated that fossil fuels benefit from subsidies of $5.3 tn a year, or $10m a minute, half of which derives from the polluters not paying the costs of health damage from air pollution...

... making electricity 100% renewable by 2050 would require affordable energy storage, both on the domestic scale and national scale. Storage technologies being targeted include better batteries, heat storage in water, soil or molten salt, compressed air, flywheels and hydrogen.

Sir David Attenborough, who recently discussed climate change in a meeting with US president Barack Obama, said: “I have been involved in arguments about the despoilation of the natural world for many years. The exciting thing about the [Apollo] report is that it is a positive report – at last someone is saying there is a way we can do things.”...

Nothing strange there at all. The entire warming thing is being orchestrated behind the scenes by big oil to drive the price of big oil up. Much of the green companies are owned by big oil. Nothing strange there at all. ;-)

Now this man is running BP.
Carl-Henric Svanberg is a Swedish businessman and current Chairman of BP and Volvo..
On 16 June 2010, Svanberg met with US President Barack Obama to discuss BP's responsibility for the effects of the Deepwater Horizon oil spill. He caused a PR uproar by afterwards expressing BP's concern for the common people along the Gulf Coast of the United States whose livelihood is threatened by the oil spill by saying, "We care about the small people", drawing upon a Swedish phrase, den lilla människan. The correct translation of the Swedish phrase would have been "the common person". Svanberg subsequently apologized for the term and attributed his unfortunate choice of words to a "slip in translation".

Part of a solution but to my mind all still an unholy silly game and contest and for a very greedy few, our planet and everything be damned:


Can the divestment movement tame climate change?

An increasingly popular tool in the fight against climate change is emerging - "divestment"...

... Campaigners point out that fossil fuel reserves that haven't yet been extracted are thought to equal five times the amount of carbon that can be burnt if climate change is to be limited.

Yet oil, gas and coal producers are still factoring in the burning of those reserves when calculating their companies' financial worth.

A recent report by Deutsche Bank pointed out that any deal on emissions at an upcoming November gathering of world leaders "means accepting that the entirety of the world's known fossil fuel reserves cannot be extracted and burned".

The authors say that this means that oil producers will try to maximise the benefit from their product while they still can - which is why the oil cartel Opec is refusing to cut production, even though prices remain low. ...



And yet reckless oil exploration is being pushed into the Arctic and elsewhere...

How do we turn around such corrupt insanity?

Meanwhile, politics and corrupt Fossils lobbying is getting worried about just how successful is UK Wind Power?


End of wind farm subsidies 'could cost Scotland £3bn'


... About 3,000 wind turbines across the UK are awaiting planning consent.

Scottish Renewables said the move was "neither fair nor reasonable"...

... First Minister Nicola Sturgeon said the decision was "wrong headed, perverse and downright outrageous." ... She added: "This decision comes despite the UK energy secretary admitting on radio this very morning that onshore wind is one of the most cost-effective ways of developing renewable energy."

Ms Sturgeon argued that the move would also send out the wrong message ahead of a conference in Paris later this year aimed at getting a new global agreement on climate change.

The Scottish government believes the decision would have a disproportionate impact on Scotland, as about 70% of onshore wind projects in the UK planning system were in the country...

... "These are projects that could provide the equivalent electricity demand of 1.23 million Scottish homes and significantly improve our energy security, while bringing around £3bn of investment."...




Sounds just like the arguments for Fossil Fuels Polluting Oil but without the excess of pollution...
