some alternative views
Dear Dino12,
no offense, but I would like to offer some alternative views to your statements:
People should know that these windmills never pay for theirselves, ever.
I would not call 10 years "never"...and for the ones that are near the coast its often 6 years. One turbine costs more than 1 million $, you do the maths. I'd love to have one for myself any day.
Also, for every Megawatt produced by wind and solar it has to be backed by either coal or nuclear.
For Coal and nuclear they need a good amount as a backup anyways, mostly a huge windfarm can be added with no more backups.
Alternative energy is not that reliable.
How many times have you driven by a wind farm with hundreds of windmills and only seen 15 or 20 operating?
6% unscheduled downtime plus 6% scheduled downtime a year for the average coal plant vs. 2% total for wind turbines. Plus if a wind turbine is down you lose less than 10MW, compared to a full coal or nuclear PP drop of 500MW in average.
We are also talking about a smart energy grid, not the locally limited system we have today. Somewhere you have wind and somewhere you have sun.
It won't be possible to replace every coal/nuclear PP by these variable resources, but it is possible to do a lot better as we do now. Today when we have a lot of wind the windparks are often limited in power output by more that 50%, because the grid cannot transport it far enough, and coal/nuclear is too slow to adapt and therefore kept on maximum.
Over the next 4 to 5 years over 21,000 Megawatts are being shut down across the US as a result from the EPA's regulations that have been set forth. Thousands of jobs will be lost. I was at a power plant the other day and 90 people were laid off because of the repercussions from the regulations. People will start bitching when they lose power everyday and their bills double. Coal is not as bad as the public is led to believe.
As I always say: People should not live with their eyes closed about what happens tomorrow... In the US you guys have 174.000 people working in the coal industry, in germany we already have 90.000 working in the wind power sector alone...thats even we are only 81million germans compared to 313million americans (numbers according to wikipedia). I guess coal dust is not very healthy either...but I'm not an expert in this area.
Btw, I chose to change my job towards the wind sector a few years ago and couldn't be happier about the decision, as the last thing I worry about is to find work anywhere on the planet ;-)
I actually found the article very interesting, as I didn't worry about the energy consumption of those data centers at all, I thought they could cover it easily with the solar farms they build. If its really only 10%, they should try to do better, although I would consider some other posts that mentioned energy savings by the move of data from local servers to the cloud.
As for groups like Greenpeace, I believe without them many good changes would have taken much longer in the past, as people & industry take the way of least resistance possible. C'mon we're all lazy sometimes, even if its only that we're too lazy to worry about windows problems
And yes, I receive green energy at home, it's a lazy contribution, but I sleep better
Have a good day everyone.
