The IEA and climate negotiators want to set a target for shifting the economy to run on electricity.

But first, some numbers:
With $100 worth of gasoline, an internal-combustion-engine car would go 862 miles; with $100 worth of electricity, an electric vehicle would go 2,310 miles—nearly a threefold advantage for the EV.
For home heating, $100 would buy enough fuel for a gas boiler to provide 30 days of heating; it would also fund enough electricity for a heat pump to provide 42 days of heating—a 40 percent edge for the heat pump.
Outside the wealthiest economies, the case for electrification is tougher to make, said Chuks Okereke, professor of global climate governance and public policy at the University of Bristol in the United Kingdom.
I'm on a natural gas furnace, not a boiler, but last I checked (admittedly two or three years ago) my home heating cost would double if I switched to a heat pump. That was assuming 90% efficient furnace, and 300% efficient heat pump.The article said:For home heating, $100 would buy enough fuel for a gas boiler to provide 30 days of heating; it would also fund enough electricity for a heat pump to provide 42 days of heating—a 40 percent edge for the heat pump.
Electric utilities: “Ho, ho! Sounds like our rates are too low!”
We spent $6 trillion blowing up, rebuilding, and blowing up again Afghanistan, all for the same form of government that was there when the decision was made to invade to return after two decades. We spend (near enough) $1 trillion a year on the ability to do that again. We spend > $ 1 trillion a year on overhead with a for-profit health insurance system when Medicare for All could reduce that overhead enough to free up a trillion a year.Medlock thinks arguments in favor of electrification don’t account enough for the high upfront costs of building the systems.
Yeah, it's a global average, so YMMV. Personally, my home heating bill would be about the same with gas or with resistance heating; sure gas is cheaper per kWh but I'd have to pay the connection fee too. Someday I'll get a heat pump installed, I just need to do some ground work first to get there.I'm on a natural gas furnace, not a boiler, but last I checked (admittedly two or three years ago) my home heating cost would double if I switched to a heat pump.

I have the same utility (DTE, southeast Michigan) for both electricity and natural gas. Make of that what you will.
Yep. Pakistan has installed something like 51GW of solar, most of that over that last few years, most of that DIY installations on homes and small businesses.On the case of it not being easy except for rich countries, i don’t know if I agree, we see india skipping coal and hevay fossil options.
Pakistan and lazakhstan and other countries have been setting up local solaf home installations electrifying villages for the first time and much more cheaply then with a traditional grid.
Its hard to convert grids, and costly
But for off grid separate solutions solar is amazing, the west just isn’t used to that.
How did you determine your costs would double? I'm not saying you're wrong, just surprised at such a large increase.I'm on a natural gas furnace, not a boiler, but last I checked (admittedly two or three years ago) my home heating cost would double if I switched to a heat pump.

This matters because electrification and decarbonization go hand in hand. It means shifting nearly everything that runs on coal, oil, and gas to electricity, while simultaneously transforming the grid to run on carbon-free sources. None of this will be easy.
How is the global average only valid in the US?Disappointing article, while the messages are aspirational, it uses comparisons that essentially are only valid in the US, and surely even there there are state based differences in utility prices? So a comparison in cost/kw.hr might be more useful, ideally taking into account the differences in efficiency of say a car using electricity- over 90% and the thermal efficiency of one using an internal combustion engine - 40-50% for diesel and well below 30% for a gasoline engine. And the heat pump analogy? Leaving out the recent price increases caused by the Orange One's wars, in the UK electricity is 3 times the price of gas for the same unit of energy. A heat pump is 3 times as efficient as gas heating so the net cost saving is one fat zero. (Of course the gas boiler produces a lot of emissions- as does generating electricity unless from sun/wind or nuclear) Perhaps the article is a little too simplistic?
That’s 2 of the 3 pillars involved in the transition. The final one being elected officials."None of this will be easy."
But for once the needs of the planet and the bean counters align... which pretty much makes the transition inevitable.
You misunderstand what the targets do: they're about making sure the system can work with that level of electrification. We could wait for market signals to tell us that adding a bunch of demand will require additional supply -- which takes years to get online, so in the meantime we suffer. Or we could plan for it ahead of time and have the chargers ready for when the EVs show up, the transmission lines built, generators, etc.Till the prices came down, the world basic did pilot projects. When they did, acceleration began. Now it's roaring, and the old forces are at best slowing it a bit.
All the target setting and earnest conferences etc are really beside the point. The economics are driving the whole thing. TBH, the best thing anyone can do is improve the economics (which the companies already have some incentive to do, but government could do more with more basic research!), but that's it. There is no reason from evidence to conclude all the mandates and targets and shit really do much of anything other than signal virtue.
Whenever I've had gas or oil heating, it didn't have any backup for the blowers and pumps and thermostats. When the power went out, heat went out. For the oil heat, I was in the literal Arctic region on a microgrid that would fall over roughly every month (one common reason: ravens shorting out the grid). I considered getting battery backup, didn't prioritize it, because it didn't really matter much.Not to mention reliability; electric goes out now and then, but I have yet to experience a natural gas outage in my lifetime.
As a counterpoint, how many houses are destroyed in a catastrophic electrical explosion each year?Not to mention reliability; electric goes out now and then, but I have yet to experience a natural gas outage in my lifetime.
If the goal is to convert everything, that's a recipe for failure. Or at least it's a goal that will take a century or two to reach. It's easily dismissed as far-fetched and basically impossible.
Meanwhile, I don't know anyone who wouldn't be thrilled to reap the advantages of conversion away from fossil fuels and the cost and cleanliness benefits it brings from a much more achievable and realistic reduction of 5%, 10%, 20%, etc.
Focusing on complete conversion is counterproductive. For many, it just turns into an excuse to do nothing.
This does not make much sense. It sounds like he’s trying to claim that wind and solar have a disadvantage because they have high upfront costs, but the alternative given has higher upfront costs and higher operating costs and a higher environmental impact. This whole article reads like someone grasping at straws in a vain attempt to make solar and wind seem worse than they actually are.Medlock thinks arguments in favor of electrification don’t account enough for the high upfront costs of building the systems. A good example is how wind and solar have low operating costs but are expensive to build. Fossil-fuel power plants also are expensive to build, but his larger point is that the advantages of any option come with disadvantages
How did you determine your costs would double? I'm not saying you're wrong, just surprised at such a large increase.
Combustion heating is massively oversized compared to a heat pump, because those big boilers run in spurts rather than continuously like a heat pump does. Most people need much smaller capacity heat pumps, but a substantial portion of the contractors out there aren't doing proper Manual J calculations, relying instead of archaic rule-of-thumb sizing. Even the Manual J calculations are oversizing systems on newer, better sealed and insulated homes.
Heat pumps are generally still more expensive to operate than natural gas, but 2x is unusual. The ace card is if you can get solar at your home, though--that's when you start closing in on zero-running-cost climate control.
For anyone with an oil burner, the swap to a heat pump is a no brainer. Unless you're a private-equity captured firm that would rather keep extract profit... like the one which sold my mother a brand new air conditioner last year knowing that the oil burning furnace would be due for replacement soon and that the thousands of dollars a year in oil and maintenance would keep their lights on.
Distribution fee is already half of my bill. In theory I can select company that sells the electricity, but it won't affect that natural monopoly.Electric utilities: “Ho, ho! Sounds like our rates are too low!”
Also, solar/wind has become more attractive/predictable as even the US can't bomb the Sun…How is the global average only valid in the US?
If anything, it's probably wrong for the US since the US has unusually low fossil fuel prices.
"vain attempt to make solar and wind seem worse than they actually are" is basically the free bingo square in any game of Carbon Policy Bingo.This does not make much sense.

TL;DR: Don't let perfect be the enemy of good.If the goal is to convert everything, that's a recipe for failure. Or at least it's a goal that will take a century or two to reach. It's easily dismissed as far-fetched and basically impossible.

Tomorrows New York Times headline, probably, “Trumps innovative plan to bomb the sun to prevent further expansion of its nuclear stockpile is as daring as it is risky”Also, solar/wind has become more attractive/predictable as even the US can't bomb the Sun…
Boiler? Maybe if you have radiators. He probably has forced air heat like most houses built after air conditioning became a thing. The furnace is built into the air handler.How did you determine your costs would double? I'm not saying you're wrong, just surprised at such a large increase.

I second that on the insulation. I recently had the siding on my house replaced, and we went with cement fiber slats; this necessitated cladding the whole exterior in plywood prior to installation, and the combination of the extra plywood and the more efficient siding type made a significant difference in cooling requirements over the summer. We also had the majority of our windows / sliding glass doors replaced, which made another huge dent. Combined it looks like our cooling needs will probably be reduced by about half next summer, which is fantastic, as I live in an area where it routinely gets above 115f / 46c.Boiler? Maybe if you have radiators. He probably has forced air heat like most houses built after air conditioning became a thing. The furnace is built into the air handler.
Gas heat is still cheaper and the air that comes out of the registers is warmer than with a heat pump. Also, the electrical upgrades required for a heat pump are non-trivial for an older house.
Oil heat is stupidly expensive, and an old oil furnace is terrible for air quality inside the house, never mind outside. If you want the best low-hanging fruit for electrification, concentrate on the oil burners first. It is, as you say, a no brainer.
But regardless, the best thing you can do, and it doesn't even require infrastructure changes, is to insulate the homes. This reduces energy bills regardless of the fuel. Anything old enough to have oil heat is old enough not to have good insulation.
I used my DTE bill to get the electric and gas rates. For electric, I used the lower, off-peak night rates, on the assumption more heating would be needed overnight when it's colder. I converted each to BTU, for kWhr electric and CCF gas, using the efficiencies I posted. All the heat pump details you mention would factor into the efficiency, but at 300% I suspect I'm already overestimating it on average.How did you determine your costs would double?

Yeah, the same "grift" that gave us Tesla Motors and actually made money for the US govt. I remember that.Remember that time Obama funded Solyndra, Mitt Romney called it a grift, and the American public fixated on a tan suit and binders full of women? China funded dozens of Solyndras while we argued about nonsense.
We could choose solar today even if we gave them 10% of the subsidies we give oil. Native solar panels would be cheap in five years and ubiquitous in ten.
Edit: I will never forget because Romney also name-checked the fuel cell startup I worked for called Ener1.
