Yes, this is indeed a lot of energy." That is not true. A watt is a unit of power, or the speed of the energy "flow". To know the actual "distance" traveled, or the energy consumed, you need to multiply this with a unit of time. Then you get an amount of energy (just like speed is related to distance via time). W = P * t; d = v * t; TWh is most commonly expressed in relation to something else, like per year. You could also have a battery with a few kWh of energy storage. Or a tank full of gas with so much energy in it. Battery capacity is most often expressed as Ampere-hours though. You must multiply that with the battery voltage to get the actual watt-hours. See http://www.camerahacker.com/Definitions/Battery_Capacity_Conversion.shtml for example. The 473TWh electricity consumption per year in your case comes down to 473 / (365*24) = 53 GW of continuous power. Obviously, more capacity is needed because the load is not continuous. “200 TW-h, what is that ? 200 Tera Watts per hour, or if you prefer figures : 200,000,000,000,000 watts per hour.
