I've been meaning to do this for over a year now and I'm really pleased I've actually done it!
Mind you, no-one ever got rich from poetry :)

accomplishedI wanted to take an opportunity to respond to some of the more usual complaints against wind farms, generally found in newspaper letters pages, and here is as good a place as any.
* "Wind farms are ugly". This is a statement of opinion, not fact. Other people find them serene and calm, perhaps even beautiful. Roads may be ugly but because they are useful we grudgingly allow them existence. How something looks is not the entirety of its value.
* "Wind farms are noisy". Objectively, detailed noise studies are carried out before the wind farm is built, and where necessary mitigation measures are put in place, up to and including reducing the power supplied. Subjectively I have stood inside the boundaries of a wind farm during high wind, and though I could hear the turbines the wind itself was far louder. People say it induces headaches; I don't understand how it could.
* "They don't generate unless the wind is blowing". Ah yes, another startling insight from the people who brought you "isn't the sea wet" and "it tends to get dark at night". All generators need an energy supply, that's how they work. For a hydro station it won't generate if there's been a sufficient drought. Wind turbines need wind. We're exploiting a natural energy resource, and it seems impolite to complain that it doesn't come when we call.
* "Wind farms are unreliable/unpredictable/inefficient". Wind farms are an intermittent power source. Generally wind farms are expected to work to 97% availability, which is pretty reliable. Energy trading uses short term forecasts of windiness to predict wind farm output, and although the techniques are fairly new generally they do better than guesswork. And a 30% capacity factor for a nuclear or coal generator is indeed very inefficient, but in wind the capacity indicates only whether the wind is there. A lack of wind may indicate poor placement of the windfarm, but pre-construction industry-wide analysis techniques have been developed to reduce the likelihood of this. No-one is stupid enough to build a wind farm and expect continuous wind speeds of 12-20 m/s for its entire lifespan.
* "Companies are getting rich from the subsidies". Actually wind farms are very expensive to install (more so offshore) and slow to recoup their investment. Given the fact that until only a couple of years ago we were developing more MWs of wind than we had running, companies are taking large-ish financial risks, even including the subsidies.
* "Wind farms can't provide baseload supply / follow the supply and demand". Firstly, true or not, this in no way reflects upon a wind farm's usefulness: just because a battery can't power your tumble drier doesn't mean we should abandon batteries completely as a bad idea. Secondly, two methods that I know of are being developed to cope with this: energy storage solutions such as pumped hydro schemes and gas storage; and smart appliances which reduce the on/off peak demand variation. Finally, no-one I've ever met thinks wind turbines are the whole of the answer. They are part of the answer. That's enough.
* "We should stop investing in onshore wind farms and put our money into offshore wind / wave / tidal power" You do that. The people developing these technologies will be thrilled, I'm sure. But while all of these technologies will prove very useful, they are many years behind onshore wind in terms of development. All renewable technologies require a responsive, intelligent grid infrastructure, and if we stop building wind farms to wait on these technologies to mature we may find when they do that the grid simply can't keep up with the balance. The pace of development meams the grid can adjust more slowly to onshore then offshore wind demands, and wave and tidal can be incorporated as it reaches maturity. Besides, if we're going to just sit and wait on an answer, why not wait on cold fusion?
* "The answer is to build more nuclear power stations". Maybe, but again nuclear is only part of an answer: wind can't be used as baseload, nuclear is unresponsive and hard to vary with supply and demand. They can work together. Also, being fuel-based nuclear isn't strictly renewable, and there are ongoing carbon costs in supplying the processed fuel.
* "We should put generators where the cities are". No, we should put solar panels where it's sunny and wind farms where it's windy and develop smart grids that can cope with that. Generators near cities is fine for fossil fuels, but fossil fuels are carbon-based and we know that's not the way to a better future.
It also seems to me that people get kind of lost in the global warming "debate". Actually the basic logic is fairly straightforward:
* Does increased CO2 lead to warming in sufficient concentrations? Yes, the planet Venus is about 200degC hotter than it should be due to a runaway greenhouse effect.
* Are man-made processes contributing to increased CO2 levels? Yes, we've been burning huge amounts of carbon for the past 300 years, while simultaneously cutting down forests and polluting the oceans. The resulting gas has to go somewhere.
* Are natural processes also occuring which vary the climate or increase greenhouse gas emissions? Yes, of course they are. They're somewhat difficult to change, however, so perhaps we should try taking the plank out of our own eye before worrying about the speck in our neighbour's eye...

One thing is for sure, life is going to change, and all I can do is take it one day at a time.

Lj has an iphone app which lets you post and read your friends list. Which means I may conceivably be spending more time on livejournal again. :)
When I come home from a day on the computer, nine times out of ten I don't want to switch on the computer. This has gotten worse with pregnancy, too.
