Now, see where I said "at today's power prices"? Prices will only go up. We can pay an upfront price now in a large lump sum, or we can pay several times that over the next 30 years. You call it substitution of cost, I call it massive reduction in cost. The largest cost of a data center is power, which I've dealt with in two ways.
Why should the prices go up if even
you can provide power for less.
Wouldn't the market regulate itself with new suppliers?
Ask your parents what they used to pay for electricity before you were born. It was much lower than what they pay now.
The prices are only going to continue going up, and there is no indication this will stop. The market is already heavily regulated and power companies are operated as state sponsored legal monopolies.
That was a rhetorical question.
Income and inflation outweigh the price increase - so in fact it has become cheaper.
Panel prices will also drop.
Wind powered energy is still technologically advancing, also.
Don't confuse USD inflation with bitcoin inflation.
I wold not object to solar panels as a political project, but that should not be part of DMC, and even than it would only work if the calculations are founded on solid data.
Its been part of the plan since the beginning. If you don't like it, then don't invest.
If you are able to do the calculations, I won't object.
Here in Maine, since I moved here 23 years ago, power prices per kwh have doubled while my kwh monthly usage has decreased. My entire bill is not kwh, so my overall bill hasn't doubled; but compared to USD inflation, USD has not inflated that quickly (only 85%).
I've done some of the calculations for solar earlier in the thread and in the op: it costs about $700 per 1kw of panel installed which produces 1200kwh actual per year in Maine. According to the EPA's Electric Power Monthly report*, commercial electricity is 10.76 cents a kwh, industrial 7.49 cents a kwh; these are retail prices include distribution/transmission overhead (for example, I pay 0.071 per kwh from the supplier, 0.068 per kwh for the distribution, 0.023 for the transmission, for a total of 0.162 cents per kwh for residential, which is actually a tad higher than the EPA's report). Maine pays net energy billing for facilities 660kw or less with a rolling 12 month window, plus I can resell power back to them at wholesale rates (a little less than than the 0.071 cents/kwh from the supplier in my above example) for anything over that.
Now, that cap is 660kw not 660kwh. As in, I could install 660kw panels of panels and generate 792Mwh a year of power and pay effectively $0** to Bangor Hydro, our local power company, for the first 792Mwh of usage of the year.
792Mwh would cost me (assuming a commercial rate instead of industrial, I'm not sure what the minimum is to get into industrial) $85,219. 660kw of panels would cost $462,000 to install, or only a little under 6 years at current rates. These panels will last about 30 years give or take, so at today's rates that is $2.556 million dollars of electricity for an up front cost of $462,000, or about 5.5 times cheaper power. The same numbers for industrial are $1.779 million, or 3.8x cheaper.
To further run the numbers, 792Mwh a year, 22kw per rack maximum usage including cooling, that is 4 racks fully loaded at 24/7 max power usage, or about 8-16 loaded more conventionally.
Edit: $700 per 1kw does not include single/multi-axis tracking systems. Here in Maine they tend to not be worth it, although because panels are getting smaller/energy densities are getting higher, they may be worth it in the future.
