The average cost of residential power in 1970 was $0.02 per kWh. Today, it's four times that. Just since 2000, rates have escalated 6 to 8% per year. Extrapolating rate increases at 8% per year (if they don't go higher than 8%), we're looking at $0.17/kWh in 10 years, $0.37/kWh in 20 years.

My use of 1528kWh last month would cost, respectively, about $260 in 2020, and $565 in 2030 (flat rate, no reduction for off-peak hours).

There are always more things to consider than today's knee-jerk-reaction prices.
