The energy needed is 237 kJ per mole (from your link - see under "thermodynamics"). 237 * 55.6 => 13.2 MJ of energy for a liter of water. In terms of power, this is 3.67 kW for one hour.

Rewrite log2 (8) = x log 2 (8) = x in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b does not equal 1 1, then logb (x) = y log b (x) = y is equivalent to by = x b y = x. Create equivalent expressions in the equation that all have equal bases.
For example, raising 2 to the power of 3 gives 8: displaystyle2³=8. The logarithm of base b is the inverse operation, that provides the output y from the input x. That is, displaystyley=logbx is equivalent to displaystylex=bʸ if b is a positive real number.
11 Αυγ 2013 · It means that per mole water splitting requires at least $241.8\ \mathrm{kJ}$ of energy. Any method(thermal,electrolysis etc) followed, this much of energy will be always required. When using electrolysis, it may be convenient to express it in $\mathrm{eV}$.
(a) Energy is required to partially overcome the attractive forces between molecules in a solid to form a liquid. That same energy must be removed for freezing to take place. (b) Molecules are separated by large distances when going from liquid to vapor, requiring significant energy to overcome molecular attraction.
