Carbon Dioxide Emissions From Electricity​

(Updated May 2021)

• Over 40% of energy-related CO2 emissions are due to the burning of fossil fuels for electricity generation.
• All electricity generation technologies emit greenhouse gases at some point in their life-cycle.
• Nuclear fission does not produce any CO2. For both nuclear and renewable generation, emissions are produced indirectly, for example during the construction of the plant.
• Over its life-cycle, nuclear produces about the same amount of CO2-equivalent emissions per unit of electricity as wind, and one-third that of solar.

Energy-related greenhouse gas emissions account for the majority of all anthropogenic emissions – about 80% in the USA and the European Union, for example. Just 20% of final energy consumption is in the form of electricity, but the generation of electricity is responsible for over 40% of all energy-related emissions.

Worldwide emissions of carbon dioxide (CO2) from burning fossil fuels total about 33 billion tonnes (Gt) per year. About 44% of this is from coal, about 34% from oil and about 21% from gas. According to the International Energy Agency (IEA), the power sector accounted for nearly two-thirds of global emissions growth in 2018, with coal use for power generation alone producing 10 Gt of CO2.

The impacts of electricity generation go beyond the emission of CO2 and other greenhouse gases. For more information see pages on:

But it seems fairly obvious to me.
Electricity comes from burning fossil fuels, just like ICE cars burn fossil fuels.
So electricity can't be any cleaner, considering all the transmission and battery wastes.
One advantage of an ICE car is that you stop burning fuel when you park and stop, but electricity generation has to remain constant, regardless of current usage.

Then you should be for alternative energy like windmills and solar panels. Our electricity doesn't have to come from fossel fuels and we're trying to do better.

For example future ebikes will power themselves by peddling.

I'll keep reading the rest of what you posted.

And I'm all for nuclear giving us our electricity. Make that shit safe but it burns for 1 million years.

Yes I agree with wind and solar, have spent the $13k to install roof panels.
Reduced my bill to $20/month.

But wind and solar is not consistent enough, so requires wasteful batteries.
Not a total solution.

Nuclear may be best?

Ebikes can not power themselves by pedaling.
That has to take more effort than just a plain pedal bike, unless you mean you pedal down hill and get it back on uphills?

 

[Blues Man]

Gasoline ICE can run on bio fuels like ethanol or hydrogen instead, and all diesels are automatically 4 times more efficient than gasoline because they have much higher compression ratios but controlled injection to prevent pre-ignition.
That is way more efficient and cleaner than current electrical power production.
The only way electric could be made cleaner than ICE is with nuclear power generation, which apparently is not happening.
Oil and gas electrical production is not going to last more than 3 years, so electrical really means coal, which is by far the dirtiest.

And again, the killer for EVs are the batteries. It is not just the slow recharge, short life span, and high cost, but the energy waste to charge, discharge, and weight to push uphill.

Electric motors DO take a long time to up the RPM is you have them direct drive to a heavy vehicle.
Electric motors rapidly loose efficiency outside their ideal RPM range, and all EVs do use direct drive that is constantly out of ideal range.
A drill is not linked to direct drive.
Jam the drill in a vise and it will start smoking in seconds.

Where are you getting your numbers?

Diesel engines are less than 50% efficient, gasoline engines less efficient than diesels

Hey demofks, where is all the extra electricity coming from to power all of your new EV products?

Hydroelectric is the only reliable renewable. And it is awesome where it can be used.

And it's a no go for future electricity so we have all the hydro we're going to get

indeed, always has been. Hoover Dam is a wonderful electrical fuel source.

 

[jc456]

that's sad. Let's go with the new nuclear fusion.

that source isn't in the future of demofk plans, and those are the sources I'm asking him to demonstrate are reliable to take over the grid of coal, natural gas and hydro.

 

[Blues Man]

that's sad. Let's go with the new nuclear fusion.

Maybe in a hundred years

 

[jc456]

Maybe in a hundred years

well, at least that's a target date.

Using its Integrated Kinetic Energy Recovery System, the VELLO Bike+ converts mechanical energy into electricity to power a 250-watt motor. "You can ride up to 15 miles per hour for unlimited mileage in 'self-charging mode,' or in 'turbo mode' up to 18-30 miles on a full charge without any effort," the company says.

Now the haters will chime in.

Diesel engines are less than 50% efficient, gasoline engines less efficient than diesels

That is correct.
But the point is electricity generation is only about 5% more efficient than gasoline engines, and once you add the battery weight to an EV, as well as energy losses both into and out of the battery, then gasoline engines are about twice as efficient and reduce pollution compared to EVs.
The claim EVs are zero emissions is absurd.
They actually pollute more.

No links to back up these claims? I should be able to google what you are claiming and find plenty of support for what your saying. Or you can provide a link.

So far this is what I'm finding

Electric motors makes vehicles substantially more efficient than internal combustion engines (ICEs). Electric motors convert over 85 percent of electrical energy into mechanical energy, or motion, compared to less than 40 percent for a gas combustion engine.

Here is something that backs up your claim


That is because natural gas appliances are generally much more efficient than electric appliances. ... An electric range uses three times as much energy as natural gas burners to produce and deliver the same heat.

Then I found this

AEVs are far more efficient than conventional gas-powered vehicles: AEV batteries convert 59 to 62 percent of energy into vehicle movement while gas powered vehicles only convert between 17 and 21 percent.

Simple, just put the EV fire out with CO2 fire extinguishers

The efficiency of the turbines that produce grid electricity have nothing to do with the efficiency of electric motors or electric cars

And no car is zero emissions.

There is a break even point where an EV will become cleaner in terms of carbon footprint compared to a gasoline powered car.

Lifetime carbon emissions of electric vehicles vs gasoline cars

Reuters analyzed data generated by an Argonne National Laboratory model to determine at what point a typical electric vehicle (EV) becomes cleaner than an equivalent gasoline car in terms of its lifetime carbon footprint.

www.reuters.com

the data showed that a Tesla Model 3 in the United States, for example, would need to be driven for 13,500 miles (21,725 km) before it does less harm to the environment than a Toyota Corolla.

The break even point differs in different size cars and different electricity production mixes but there is a point where an EV has a smaller carbon footprint than a gasoline powered car. The smaller the car the sooner that break even point is hit

The efficiency of the method that produces grid electricity most definitely does matter.
Coal is still the main source of electricity in the world and in the US, and electrical production is only very slightly less polluting then an internal combustion vehicle.
Once you add in the extra weight of the batteries and the battery energy losses, then EVs pollute much more than ICE.

It is easy to make ICE cars zero emissions.
All you have to do is run them on bio fuel that absorbs more emissions while growing, than it returned to the atmosphere when consumed in the bio fuel vehicle.
And that is easy to do.
For example, a diesel can be run on palm oil, which is just from harvesting the annual fruit of a tree that can live for hundreds of year, and then turned into furniture.

If the electricity is coming from coal, as most electricity does, then there is no break even point.
Then EVs always pollute more than internal combustion vehicles.
The obvious reason is that internal combustion vehicles weight half as much.

Coal is used to produce 19% of the electricity in the US.

And since our grid runs on baseline power and most people would be charging an EV at night there really wouldn't need to be an increase in power production and the emissions produced from electrical power generation wouldn't really increase and even if they did it would still be a net reduction in emissions if more people drove EVs
