Wave

To calculate the wave energy of the Netherlands a couple of item are needed. The length of coastline, the population and the power in one wave. In Mckay, he uses 40 kW/m as the power of one wave. The Netherlands has a population around 16500000 people and a coastline length of 350km. The power generated can be calculated by the following equation:

(power of one wave)*(coastline length)*(population)

(40 kW/m)*(350,000 m)*(16,500,000 people)*(24 hours/day)=

20.4 kWh per person per day

Now that value is calculated using 100% of the coastline and assuming that the Netherlands is 100% effiecient at turing the wave energy into power which is not possible. Assuming 50% for both the coastline and effieciency is more reasonable but that will decrease the power by 25%.

(20.4)*0.25 = 5.1 kWh per person per day

Biomass

The average havestable sunlight that the Netherlands have is about 100W/m^2. Europes most effiecient plant is close to 0.5% according to Mckay. That brings the value of sunlinght to 0.5 W/m^2. The netherlands is very compact so only 60% of the country could be covered. The enerygh produced by biomass is calculated in the following equations:


(60%)*(41,000 km^2) = 24600 km^2
(24,600 km^2)*(1ooo^2 m^2/km^2)/(16,500,000 people) = 1491 m^2 per person

(0.5 W/m^2)*(1491 m^2/ person)*(24 hours/day) =

17.9 kWh per person per day

This is still not a good assumption because effieciency is still a factor. In Mckay he uses an efficiency of 66.66%.

(2/3)*17.9 = 11.9 kWh per person per day
