Marine energy

1. Annual electricity consumption in HK
40,000GWh per year

where 1 kWh = 1 kW x 1 h. = 1 000 Wx 60 x 60 s. = 3 600 000 J and 1J = 1 Nm or 1 Ws

2. Potental energy
PE = weight x height = mgh

3. Wave Power (from EMSD)

The power P (in W/m) in an idealized ocean (deep-water) wave is given by the following expresion:


P = pg^2H^2T/(32*pi) watts per metre wave front
or approximately H2T kilowatts per metre wave front


where, p is the water density
H is the wave height in metres (the vertical distance from wave trough to wave crest)
T is the wave period in seconds
