  • Here you go, you’ll need numpy, scipy and matplotlib:

    from scipy.optimize import curve_fit
    from matplotlib import pyplot as plt
    
    # 2010-2013 data from https://ourworldindata.org/renewable-energy [TWh]
    y = np.array([32, 63, 97, 132, 198, 256, 328, 445, 575, 659, 853, 1055, 1323, 1629])
    x = np.arange(0, len(y))
    
    # function we expect the data to fit
    fit_func = lambda x, a, b, c: a * np.exp2(b * x ) + c
    popt, _ = curve_fit(fit_func, x, y, maxfev=5000)
    
    fig, ax = plt.subplots()
    ax.scatter(x + 2010, y, label="Data", color="b", linestyle=":")
    ax.plot(x + 2010, fit_func(x, *popt), color="r", linewidth=3.0, linestyle="-", label='best fit curve: $y={0:.3f} * 2^{{{1:.3f}x}} + {2:.3f}$'.format(*popt))
    plt.legend()
    plt.show()
    

    Here’s what I get, global solar energy generated doubles every ~3.5 (1/0.284) years.







  • The mistake you make is that you assume the law works the same in China as in countries that have rule of law. China doesn’t have rule of law, they have ‘rule by law’. The Communist Party isn’t just above the law, the law is a tool for them to use how they see fit. If you are undermining the Communist Party then that is by definition misinformation.

    Remember, this is the same country where one day the minister of health aplauded a journalist’s effort to combat pollution with a documentary called under the dome, and the next day it was gone from the internet as if it never existed. Whenever they have internal issues they stir up some hatred for the USA or Japan, only to be forgotten somewhat later.

    They took 1984 not as a warning, but as a manual
