# Energy Consumption Stats

• Average yearly usage of 10.812 MWh (Megawatthours)
• ~30 kWh daily usage

Highs of 15.435 MWh (~42.28 kWh/day) to lows of 6.166 MWh (~17 kWh/day).

As of now, for a consumer solar it's about $1 per Watt of solar. Assuming a 12 hour window of sun at full power, and 36 kWh usage, thats 3 kW or about$3k for the solar panels (at about .6x1x.035 m^3).

As of now, for consumer deep cycle lead acid batteries, it's about $.15 / (Watt hour). At 36 kWh, thats about$5400.

A LiFePO4 32650 5.5 Ah 3.2 V rechargeable battery goes for ~$120.00 / 80 units. At 36 kWh, that works out to about (120 / (80 * 5.5 * 3.2)) * 36000 =$3070

This does not include all the control hardware and electronics that are needed for proper usage.

As a rough estimate, New York average price for $.1854 / kWh at 601 kWh / month for about$111.32 / month or \$1335.84 / year.

## Future

Interestingly, I think the blog post was trying to point out the absurdity of continue economic growth but I take it as a rough time frame for our progression on moving up the Kardashev scale.

There's some talk about wealth and CO2 emissions going hand in hand, with some suggesting a total civilization collapse (from "Decline of the Empire" blog).

One post claims solar produces 20-30x less CO2 than coal, so I'm not sure if apocalyptic forecasts are to be believed.
