1.21 GW would be the entire peak output of one of the largest power plants in the United States (nuclear or coal). 1.21 GW would be the output of 25 General Electric LM6000 aeroderivative jet engine generators. 1.21 GW would be the output of about 3600 Chevrolet Corvette LT1 6.2l V8 engines.

My air conditioner at home uses about 5000 watts, when it is running. 1.21 GW will power 1.21 x 10^^9 /5000 = 242,000 of those houses.

To get a sense of how much that is, an average American household uses 10,812 kWh of power in a year. Consuming energy at a rate of 1.21 GW uses the same amount of energy in about 30 seconds.

First of all, gigawatts is not a measure of energy, but of power. Power is energy per second. If energy is like distance, power is like speed. It’s a rate of energy transfer, not a measure of energy itself. One way to imagine how much power that is, is that 1.21 GW is about a million microwave ovens running at once.

It is not a measure of an amount of energy. Watts are a measure of the rate of energy usage. One point 21 gigawatts is the rate of a 1.21 billion Joules of energy used in one second. About $98,000 dollars per second.

My Tesla’s EPA rating is 26 kWh per 100 miles. So 1 MWh would take you 3,846 miles. PET HATE:A watt (or a kilowatt or a megawatt) is a measure of how fast electricity is flowing.If you’re talking about an actual amount of energy then you have to talk about watt-hours (Wh) or (kWh or MWh).26 kW would be a rate of energy consumption or flow…the “power” of the system. 26 kWh would be the amount of electricity a 26kW system would deliver in an hour or which a 1 kW system would produce over 26 hours - which is the energy capacity.

Let’s do math. Figures used are relevant for now, 30/11/2017, around 8PM GMT. Current hashrate for BTC : 8,049,500,099 GH/s (was up to 10,400,000,000 GH/s last month) Block generation time : 12.1 minutes Bitcoin reward by block : 12.5 Most of mining ASICs are Antminer S9, consuming 1323W/h for 13.5TH/s So, to generate 1 BTC, we need 8,049,500/13.5 = 596,259 S9 running for 12.5 blocks / 12.1 min = 58.08 sec. So the consumption of energy is 596,259 S9 x 1323 W/h x (58.08sec/3600sec) = 12 726 790W, or 12,727kWh. However, the power efficiency of an Antminer S9 and its PSU is around 93%, so it’s 12,727/0.93=13.684kWh If I didn’t make a mistake, you need 13,684kWh to mine one single BTC just now. sources: BTC infos: Bitcoin Difficulty and Hashrate Chart
