Many wind schemes now also quote their expected or actual annual output in GWh, to allow more meaningful comparisons with other forms of generation than is possible just by considering this total rated output.

I read that as a rule of thumb you want around 2x the rated output to ensure the speakers aren't underpowered, so I would need an amp providing around 50W @ 8Ohm for these speakers.

For example, a common regulator such as the 7805 has an output voltage of 5V, but can only maintain this if the input voltage remains above about 7V, before the output voltage begins sagging below the rated output.

Appin longwall coal mine ( Illawarra Coal Holdings Pty Ltd ., operator ( BHP Billiton Ltd ., 100 % ) ] is located 40 km northwest of Wollongong, NSW and has an annual rated output of 8.8 million tonnes.

On the extreme end, Atma-Sphere MA-2 amplifier uses 20 6AS7 tubes per channel, with a continuous power consumption of 600 watts per channel ( 800 watts at maximum rated output of 220 watts, or a 27 % maximum efficiency ).

In one test by the U . S . Department of Energy of " Energy Star " products in 2003 04, one quarter of tested CFLs no longer met their rated output after 40 % of their rated service life.
37.
As Csmiller hinted above, small unregulated wall-wart power supplies have very poor load regulation, that is, their output voltage at no-load can be more than twice their rated output voltage ( i . e ., example, 20V at 0 mA, 15V at 20 mA, but 9V at 210 mA ).
38.
Current Energy Star guidelines for computers call for a power factor of e " 0.9 at 100 % of rated output in the U . S . Environmental Protection Agency, PCs with internal power supplies will require the use of active power factor correction to meet the ENERGY STAR 5.0 Program Requirements for Computers.

On 30 November 2013 the Suzlon Group subsidiary REpower Systems ( now Senvion SE ) won an Engineering, Procurement and Construction ( EPC ) contract from Mitsui & Co ( Australia ) Ltd to deliver 52 wind turbines with a total rated output of 106.6 MW for the Bald Hills wind farm in Victoria, Australia.

Installation was completed of a 99-metre wind turbine with a rated power output of 900 kW . Onshore wind turbines in the UK typically operate at an average of 25 % of the rated output, so the Nuclear AMRC s turbine should generate an average of over 5000 kWh per day, equivalent to the electricity used by 500 households.
