This isn't an addition $12500 to invest, this is instead of spending this (or more) on your next 25 years electricity bill. So you might have $12500 in year one

This isn't an addition $12500 to invest, this is instead of spending this (or more) on your next 25 years electricity bill. So you might have $12500 in year one, but each year you would be eating away a good chunk of that to pay your electricity bill - and let's face it, bill aren't going to get cheaper. I'd say that pot of money would last you about 10 years max, then you have to find more cash to fund your next 15 years worth of bills.
- richardw 15y agoThe idea isn't to hold out forever, just long enough to let the innovation curve flatten somewhat. Remember, "from $4.00 a watt to $1.25 in three years". Buying now means you're locking yourself into a given year's technology and pricing for the next 30 years, exactly when the price per watt is dropping insanely.
- gritzko 15y agoThat reminds the "rifle nightmare" of the Russian Defense Ministry (1860s-1870s). Every new rifle system accepted was entirely obsolete the next year. By the time of Russo-Turkish war, the army had 10-20 completely different rifle systems in use. That was over in 1891 when Mosin-Nagant was introduced. That one was in use for 60 years, including both World Wars. (Germans had highly similar Mauser rifles.) When the paradigm is changing, investing is risky.
