About 7.5 kilowatt hours is needed to charge the Powerwall, providing about 6.5 kilowatt hours of power once charged. With some utilities, consumers can choose between flat-rate electricity pricing (the price is the same no matter the time or day or demand on the electricity grid) and peak-rate pricing.
Myth or Truth: I need 8 glasses of water a day. Myth. The Institute of Medicine says adult men actually need about 13 cups (3 liters) per day of fluid; adult women need about 9 cups (2.2 liters) of fluid. (You get about an additional 2 1/2 cups of fluid from foods.).
That's the number of ounces of water you should consume each day. If youâre a 200 lb man, you should drink 100 oz of water per day, or just about 3 liters, or just over 3 quarts. If you are a 130 lb woman, you should be drinking about 65 oz of water per day, or roughly 2 liters (or 2 quarts).
