"Wind power’s proven inability to deliver the goods when it counts has been on show in the last few months.

Much to the horror of the wind cult, renewable energy rent seekers and their political enablers.

Total wind power output collapses in Germany and across America’s midwest, have drawn focus on just how useless and dangerous weather-dependent wind power really is.

If you’ve ever driven past a fleet of motionless wind turbines, you’ve probably had that moment of epiphany, prompting the inevitable question: “well, what’s the point?”

Indeed, what is the point of carpeting the countryside with thousands of these things (each worth between $3-$5 million a pop) when they will only ever deliver power in occasional fits and spurts; in copious abundance when it’s not needed and hardly at all when it is?

... with engineers bound and gagged ... the zealots prevailed and the concept of meaningful power generation became their first victim.

... In Germany, subsidies for the energy of the future cost ratepayers some 30.9 billion Euros last year, and their power bills are the most costly in Europe, on average three times as expensive as Americans’.

... if you challenge orthodoxy you’re frequently reproached for not being a climate scientist by someone who isn’t one either.

When pressed, such people will insist that while they don’t know enough to have an opinion you should adopt theirs because they are following “the science” or listening to “the scientists” without by their own admission knowing enough to tell what the science says or which scientists to listen to.

But what about the engineers?

The most vocal enthusiasts for alternative energy, other than those pocketing the subsidies, are overwhelmingly not engineers.

... Alternative energy has been a huge disappointment until now, whatever claims are made that it’s finally becoming competitive.

Germany was in big, long-term energy trouble before the storm hit including importing fossil fuel energy which rather defeats the purpose. ...

... As Willis Eschenbach recently noted with h/t to Friends of Science, “People generally have little idea just how much energy we get from fossil fuels.”

Specifically, total world energy use is around 160 petawatt-hours/year and is expected to rise to just over 240 PWhr/yr by 2050.

And of that, on current trends, over 193 of those PWhr/yr thingies will be fossil fuels.

... “So if we are going to zero emissions by 2050, we will need to replace about 193 petawatt-hours (1015 watt-hours) of fossil fuel energy per year.

Since there are 8,766 hours in a year, we need to build and install about 193 PWhrs/year divided by 8766 hrs/year ≈ 22 terawatts (TW, or 1012 watts) of energy generating capacity.

Starting from today, January 25, 2021, there are 10,568 days until January 1, 2050.

So we need to install, test, commission, and add to the grid about 22 TW / 10568 days ≈ 2.1 gigawatts/day (GW/day, or 109 watts/day) of generating capacity each and every day from now until 2050….

... We could go all nuclear.

In that case, we’d need to build, commission, and bring on-line a brand-new 2.1 GW nuclear power plant every single day from now until 2050….

Don’t like nukes?

Well, we could use wind power

… Typical wind “capacity factor”, the percentage of actual energy generated compared to the nameplate capacity, is about 35%.

So we’d have to build, install, commission and bring online just under 3,000 medium-sized (2 megawatt, MW = 106 watts) wind turbines every single day from now until 2050….

We could use solar

,,. actual delivery from grid-scale solar panel installations on a 24/7/365 basis is on the order of 8.3 watts per square metre depending on location.

So we’d have to cover ≈ 100 square miles (250 square kilometres) with solar panels, wire them up, test them, and connect them to the grid every single day from now until 2050.”

If these numbers depress you, consider also that “we’d still need somewhere between 50% – 90% of the total generating capacity in nuclear, for the all-too-frequent times when the sun isn’t shining and the wind isn’t blowing.”

And if these numbers don’t depress you, you either didn’t understand them or were already not an enthusiast for alternative energy.

Or included nuclear in that term.

Or don’t mind a catastrophic fall in living standards and life expectancy as we switch off the grid.

No wonder African countries are opting for old-time, reliable power.

As is India.

The third is the fundamental physics of wind and solar.

The amount of energy they can capture; the conversion rates; the physical size of the installations you’d need; the lifespan of the units.

Of course incremental improvements in engineering are not just possible, they are inevitable in the modern world.

But the kind of breakthrough that would make a solar farm output energy like a nuclear reactor or a gas turbine plant is not going to happen, because we can work ingeniously with the laws of nature but we cannot change them."
