A NIF fusion shot on September 27, 2013, produced more energy than was absorbed by the deuterium–tritium fuel. [120] This has been confused with having reached "scientific breakeven", [121] [122] defined as the fusion energy exceeding the laser input energy. [123] Using this definition gives 14.4 kJ out and 1.8 MJ in, a ratio of 0.008. [120]

The explosion of the Ivy Mike hydrogen bomb. The hydrogen bomb was the first device able to achieve fusion energy gain factor significantly larger than 1.. A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state.
Boiling water reactors generally have negative void coefficients, and in normal operation the negative void coefficient allows reactor power to be adjusted by changing the rate of water flow through the core. The negative void coefficient can cause an unplanned reactor power increase in events (such as sudden closure of a streamline valve ...
load factor = ( [ 57 200 kWh / {30 d × 24 h/d} ] / 436 kW) × 100% = 18.22% It can be derived from the load profile of the specific device or system of devices. Its value is always less than one because maximum demand is never lower than average demand, since facilities likely never operate at full capacity for the duration of an entire 24 ...
Energy released in 1 day by an average hurricane in producing rain (400 times greater than the wind energy) [179] 6.4×10 19 J: Yearly electricity consumption of the world as of 2008 [206] [207] 6.8×10 19 J: Yearly electricity generation of the world as of 2008 [206] [208] 10 20 1.4×10 20 J
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
Renewable investment reached almost $500 billion globally in 2022, [2] amounting to 83% of new electric capacity that year. [3] The renewable energy industry employs almost 14 million people. [ 4 ]
