Final answer:
The current annual relevant range of output is the yearly energy production level of a power-generating system, with variations depending on the technology and efficiency, such as nuclear power plants with 300 GW out of 400 GW capacity, hydroelectric potential at around 0.5 TW, and solar power requiring 6.25 m2 for 30 kWh per day based on average intensity.
Step-by-step explanation:
The current annual relevant range of output refers to the amount of energy a particular system or technology produces over the course of a year. In the context of power generation, it is important to know the average power output of a facility to understand its contribution to the overall energy supply. For instance, a nuclear power plant may have an installed capacity of 400 GW, but its actual produced power is about 300 GW which is a substantial share considering the world's usage. Similarly, hydroelectric potential estimates indicate that while there is a technically feasible potential of about 2 TW, only 1 TW may be economically viable, implicating that we currently harness roughly half of the practical limit for hydroelectricity.
When evaluating solar energy, for instance, the variance in solar intensity across locations is less drastic than one might expect. Annual outputs from solar tend to vary within a factor of two, even between extreme environments. Assessing the practical application of solar power in various regions, it is indicated that if one aims for 30 kWh per day, approximately 6.25 m2 of solar panel operating at 100% efficiency would be required, based on an annual average input of 4.8 kWh/m2/day.
