Gettin' old, but still a hippie at heart...


Okay, it's long, but in part it's continuing the discussion of whether we have time to save the earth or whether we should "get out while the getting's good":
Quote:

The engineering solutions to combat climate change already exist. Politicians must be brave enough to use them before it's too late

One word sums up the attitude of engineers towards climate change: frustration. Political inertia following the high-profile failure of 2009's Copenhagen climate conference has coupled with a chorus of criticism from a vocal minority of climate-change sceptics. Add the current economic challenges and the picture looks bleak. Our planet is warming and we are doing woefully little to prevent it getting worse.

Engineers know there is so much more that we could do. While the world's politicians have been locked in predominantly fruitless talks, engineers have been developing the technologies we need to bring down emissions and help create a more stable future.

Wind, wave and solar power, zero-emissions transport, low-carbon buildings and energy-efficiency technologies have all been shown feasible. To be rolled out on a global scale, they are just waiting for the political will. Various models, such as the European Climate Foundation's Roadmap 2050, show that implementing these existing technologies would bring about an 85 per cent drop in carbon emissions by 2050. The idea that we need silver-bullet technologies to be developed before the green technology revolution can happen is a myth. The revolution is waiting to begin.

Climate call

The barriers preventing the creation of a low-carbon society are not technological but political and financial. That's why at a landmark London conference convened by the UK's Institution of Mechanical Engineers, 11 national engineering institutions representing 1.2 million engineers from across the globe, under the banner of the Future Climate project, made a joint call for action at December's COP17 climate change conference in Durban, South Africa.

The statement calls on governments to move from warm words to solid actions. They need to introduce legislation and financial support to get these technologies out of the workshop and into our homes and businesses and onto our roads. Targeted regulation and taxation will also drive innovation. This will require bold politics, and spending at a time when money is scarce. It is far from unaffordable, however. The UK's Committee on Climate Change, which advises the British government, continues to support the view of the Stern report – an assessment of the climate change challenge in the UK – that the move to a low-carbon society will cost no more than 1 per cent of GDP by 2050.

Resistance to wind turbines and the power lines they feed, nuclear power and electric cars, as well as the economic costs, all make public opinion a powerful brake on change. However the alternative seems certain to be worse. It is not only the challenges of a deteriorating climate: with inaction comes a great risk to our economy in the long term. The green technology revolution, just like the industrial revolution before it, will give jobs to those countries which have created the right conditions for it to flourish.

China in front

Which countries these will be is still an open question. India, Germany, Australia and the UK were among the nations signed up to the Future Climate statement, whereas the world's largest greenhouse gas emitters – China and the US – were not. When it comes to investment in clean technology, however, that's not the whole story.

Although China is continuing to build coal-fired electricity plants at an alarming rate to power its rapid economic growth, the UN Environment Programme confirmed last month that it is now by far the world's biggest investor in renewable energy. Last year, China's wind, solar and biomass power industries received $49 billion of new investment, a third of the global total, and it now has the largest installed wind capacity in the world. When predicting who the front runner in this next great technological revolution will be, it is difficult to see past the emerging superpower to the east.

The US is going in the opposite direction. A natural gas rush driven by the development of controversial "fracking" techniques over the past decade has echoes of the oil rush that transformed Texas a century ago. The Financial Times reports that just one company, BHP Billiton, is investing as much as $79 billion in US shale gas fields – over three times the amount invested in all US renewables in a year. This will secure cheap energy in the short term, but it is a finite resource and ultimately a dead end. In due course we could face the interesting prospect of the US turning to China to acquire its wind turbine technology.

Nuclear elephant

Investment in renewable energy is vital for a prosperous, low-carbon society. However, decision-makers cannot ignore the elephant in the room – nuclear power. The enormous cost of implementing 100 per cent renewable power is not realistic for most nations, so nuclear offers our best chance of making a low-carbon society achievable and affordable. Yet the incident at Fukushima earlier this year has reinforced some long-standing concerns.

Unlike road use or smoking, nuclear power stirs anxieties in many of us that are out of proportion with its true risks. This is not to be complacent about the potential danger of a nuclear plant, but it is striking that nuclear power has killed fewer than 5000 people in its entire history. Compare that with coal mining, which in just one year and in one country – China in 2006 – killed 4700.

Read full articleContinue reading page |1 |2 Germany's decision to phase out all nuclear power as a result of Fukushima will most likely have unintended consequences. The Association of German Engineers has estimated that it will cost €53 billion every year in Germany to close down its nuclear generation and switch to 100 per cent renewable energy. It will be interesting to see how public opinion, now so clearly against nuclear power, responds as the economic costs become apparent.

Any technological revolution requires two crucial ingredients – engineers to design, develop and manufacture the technology, and politicians to help create the legislative, behavioural and societal environment that allows change to happen. Today's engineers have fulfilled their side of the bargain. It is time for our politicians to show their mettle. http://www.newscientist.com/article/dn20963-engineers-can-build-a-lowc

I was going to read this with interest, but I find myself too offended by your mischaracterization of my arguments to do so.

Suffice to say, I never, EVER put it like an either/or scenario of "save earth or vamoose." My argument was to try to do BOTH.

Good day to you.

Honey, you're getting paranoid. This had nothing to do with you, only the discussion on the subject. I never even THOUGHT of you as making it an either/or scenario, only of the various comments on both ideas. I think all you were talking about was inhabiting outer space, if memory serves, and that had nothing to do with whether we should stay or go, only about the feasibility of going...and then it got into a personal discussion, which also has nothing to do with this thread.

Why did you take it personally? I'm sorry you did, but trust me, I wasn't thnking of you at all when I posted this. I was thinking of all our various discussions on how we're screwing up this planet, and my own opinion that it's politics keeping us from repairing what we can.

If everything global warming religion tells us does turn out to be true then its already to late to avoid temperature change over the next 100 years, so why even try. We could spend the money to help people adapt to global warming and still have enough left over to buy everyone a monster truck. I don't want to live in a world with no trucks, boats, super bikes or sports cars. Engineers should be working on important stuff like making nuclear powered monster trucks and thousand horsepower jet skis, not trying to shrink cars to the size of an Atom to reduce carbon dioxide.

Ahhh, another old voice returns. This one, however, I could have done without quite nicely. You sound the clarion call of the right: "I want it all, NOW (reality be damned)!"

Freedom is Important because People are Important


Hello,

It seems to be that Kirk was using humor and hyperbole.

Keep the Shiny side up


I'm thinking that this article both underestimates the cost of going mostly or totally renewable, especially with current or near-term technology, and overestimates the amount of money politicians will be able to throw at the problem in this era of collapsing European economies.

For example, Greece, Spain, etc. aren't going to be dropping the big bucks needed for a move to renewable when they're having to be rescued by the EU just so they can pay for pensions and social services.

Also, China may be the biggest investor in renewables in absolute dollars, but invesment per-capita figures would probably come out a bit different.

"Keep the Shiny side up"

ETA: I do think it'll be interesting to see how Germany makes out trying to dump their nuke plants.

Niki, I don't think that Kirk actually left, he just doesn't post often, though I've seen his name lately.

Anthony, from his past postings, I would say not; I think he's voicing an opinion held by far too many people.

Geezer; in my opinion that's looking at the short-term situation. Nothing ever changes that fast, so by your theory, why should we even bother? It's another variation on what Kirk wrote; "It's not the perfect solution, so why even try?" That's just how I see it.

You misunderstand.

I'm all for renewable energy, but from everyting I've read, it's not sufficiently cheap, robust, or in some cases environmentally friendly in manufacture to go into large-scale production, like to provide a majority of energy, right now. There is also still the huge issue of electricity storage, since both solar and wind are cyclical.

It's pretty much the same problem as full-electric cars. They're great in certain siutuations, like short daily trips when you have fast recharging stations available at home or work, but they're sure not ready for a day's drive from L.A. to Frisco yet. Maybe some day they will, but pushing them as THE solution for right now, like pushing renewables as THE solution right now, is jumping the gun.

I agree that there is great promise for wind and solar energy but it least in the solar area its not cheap enough for large scale adoption. There are serious down sides to using wind as I discovered in my recent trip to Denmark. Denmark has the lowest per capita carbon emissions of any country in the World but they have ruined their natural landscape with enormous windmills everywhere. They may be overcompensating for the guilt the feel for clear cutting their entire country in the recent past. Wind mills might work if they could be placed offshore out of human sight.
I actually am serious about monster trucks and gas powered toys. We need to develop environmentally friendly sources of energy for everyday energy needs so we will have enough oil left to power toys for the next hundred years until we can perfect economical hydrogen fuel to power our toys. My main problem with the Global Warming wackos is that what they really want is for us all to give up our toys and go back to living in grass huts. What we should be doing is advancing to nuclear powered zero emission monster trucks not go back to horse and buggy.

"Right now"--that was my point.
