Getting rid of dirty boat fuel is likely the reason why we see this sudden rise in temperature: https://lemmy.world/comment/10570999
No we don't need to accept that, they can be better off by the end of this century than we are now.
While I get the sentiment and believe action is necessary, this is the wrong way to approach it. Panic is not the way we will solve this crisis.
There's a way out, and if we get through we'll be in a better place than we've ever been. We need to mass invest in green technology. Solar, wind, nuclear, throw everything at it and see what sticks. Solar is already on the right track to save us, but it's better if it goes even faster and have a few back up plans.
Yes, just solar. Hydro is bigger now, but it doesn't have the growing potential. Wind is currently also growing exponential, but I don't see it doing that for 20 more years. And even if it does, it doesn't really make a big difference since exponential + exponential is still exponential. If it grows as fast as solar that would mean we're just a few years ahead of the curve.
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.
Because it's called Full Self Drive and Musk has said it will be able to drive without user intervention?
Exponential, it fits the curve very nicely. I can give you the python code if you want to. I got 2 decades for all energy usage, not only electricity, which is only one sixth of that.
I just took the numbers for the whole world, that's easier to find and in the end the only thing that matters.
The next few years are going to be interesting in my opinion. If we can make efuels cheaper than fossil fuels (look up Prometheus Fuels and Terraform Industries), we're going to jump even harder on solar and if production can keep up it will even grow faster.
