Wind and Solar Capacity to Pass Nuclear

Nuclear, Wind, and Solar Capacity

Sources: IAEA, EIA, Bloomberg New Energy Finance

Wind and solar capacity are expanding  rapidly and each is well on track to pass nuclear power capacity.  Advocates of nuclear energy have long been predicting its renaissance, but the installation of nuclear capacity appears to be stalled with little to no change in recent years.  Wind energy, by contrast, will have more capacity installed than nuclear by 2015 and solar energy capacity is likely to pass nuclear prior to 2020.

Renewable Energy in Kuwait

Renewable energy in Kuwait is well supported.  The Kuwait Petroleum Company and the Ministry of Water and Electricity sponsored a joint study by the Kuwait Institute of Scientific Research to determine the potential for renewable energy given an optimal generation mix.  Study details have been presented publicly, revealing the following model inputs: wind and solar resource assessment data, RE technology costs short- and long-term, short-term hourly demand profiles, long-term power demand forecasts, power sector plant performance, and energy price forecasts.

Solar Data Animation

A solar data animation is supplied to assess quality, spatial and time series dimensions:

  • The quality dimension is a function of the availability of different sunlight components: Global Horizontal Irradiance (GHI), Direct Normal Irradiance (DNI), and Diffuse Horizontal Irradiance (DHI).

Correlation Plots in R

The standard function for correlation plots in R is pairs(), which generates a matrix of scatter plots based on all pairwise combinations of variables in a data object.  The standard graph looks something like this after a little color enhancement:” plot13Click to enlarge

The code behind this plot is simple:
