Has it? As stated earlier ICE cars currently emit 3 billion metric tons annually while power plants emit around 1.5 billion. Doubling the number of EV's will increase the the power plant emissions but will reduce the overall footprint. What about when the numbers go to 30% in 2030 or even 50% in 2050 as projected? Eventually those numbers will flip and when it does will the footprint be smaller? To really make a difference we need to replace that capacity with solar, wind or hydro to really make a difference.
Anyone own an EV?

#3 is saying exactly what I did.
I'm not totally against EV's and if I was still commuting for work 20-25 miles a day I would likely get one in addition to a ICE vehicle for longer trips. I spend a lot of time overseas and don't have a car there. I walk or ride a bike normally. There are pro's and cons to both types of vehicles.
My points on the electric grid are not just about electric vehicles. Increased A/C usage and ownership in the US along with other high use appliances (water heaters, dryers, pool pumps) have increased demand on the grid. If you drive through Texas on a hot or cold day you can actually see the lines droop due to the demand. Were only a few years removed from outpacing demand for the first time and its getting better but until we can improve the grid we should slow roll the additional demand. Right now there is 2000GW in renewable capacity waiting to be added to the national grid but it cant handle it. These improvements will take time.
There is no argument on your first sentence. I have no idea what you're referring to with the rest.
Solar and wind farms are good for the environment? I see the benefit of solar for individual homes if one can afford it as that removes the strain on power plants. I have a neighbor in Maine that has a wind turbine built early 2000. I will ask him how it has worked out when I visit in August.
Sure as it reduces your footprint. Having solar and wind is only part of the equation though. If you generate 5000kwh of power a month but have an inefficient home your wasting that energy and money. By making a home more efficient through geothermal, insulation, windows ect... your lowering your usage and electric bill. Once you get there you can add solar or wind and get to net zero or even get money back every month. That's on the individual level though.
What I meant in the post is that there are 2000GW of electrical capacity from wind and solar that cant be added to the grid due to capacity constraints. Replacing coal or fossil fuel burning plants with those renewable sources will help increase capacity while reducing C02 emissions.
Both are occurring if the warming trend is real and continues.

Due to climate change, temperatures are also rising on Greenland, which may lead to major changes on the island. Global warming is melting the ice, temperatures are rising and more fertile land is being created for agriculture. In addition, coveted raw materials become more accessible.Mar 5, 2021
Didn't answer the question. 10% from mankind? More plant growth ='s more absorption? C02 creates heat? Sun?
How much carbon dioxide does the Earth naturally absorb?
The planet naturally releases and absorbs far more carbon dioxide than humans emit by burning fossil fuels. The problem is that human activities have thrown the Earth’s carbon cycle out of balance.climate.mit.edu
The state ASKED that EV drivers charge at night. This is not a problem. This is a minor inconvenience at best. And that is during a crisis. So, no, this is not the problem the right has politicized it to be.
IF there is a problem, the simple and easy solution that untaps a massive amount of new available energy time is to drop the price of a kw after say 11PM by as little as a penny. Drop it even a penny and I'm setting my timer to 11.
You can support a massive influx of EVs with very little effort.
I have solar. I have a 5kw system that nets me around 600kwh a month. My home only uses around 800kwh so I have a regular electric bill for the rest. I was going to go with a 7kw system but with the $25 minimum bill and the buy back rate that's effectively .02 cents a kwh I didn't see it as worth it. So with average use I saved 125 a month on electric costs which would pay the system off in around 3.5 years. If you include the federal tax credit its less than that.
I have all solar and wind at my place overseas and am not connected to the grid at all. I use mini splits for heat and ac but rarely need them at all.
In some parts of the country at certain times of the year peak usage can be at night.
Not cute. Fact. In Texas and the southeast in the winter peak usage would be at night due to electric heat running during cold spells.
I don't totally disagree with you. However, its not a simple fix and will take years to upgrade the power grid in some parts of the country. I worked in that industry for years working long haul transmission lines in Texas and parts of the Midwest. We will be fine for a few years but there will be a inflection point if EV's come on before upgrades do.
Yes, of course we need to upgrade power grid. but not as much as you would think.
Your point is that off peak periods can change during the year due to seasonality. Yes. Solution: Change the off peak pricing discount period. If they say starting in October, off peak pricing starts at 4PM, people will simply change the charging start time on their car.
You can take advantage of down times with the same grid for a long time as the country keeps adding EVs.
Good idea but will the providers want to cut those rates? And if they do it would be at the expense of another sector like peak rates which would be passed on to the consumer. Maybe the government subsidizes it?
The grid has gained capacity in the last few years and is growing. Like I said we just outpaced demand in 2019 but there's a lot of potential out there that cant be added due to grid limitations. Another big step would be connecting the entire grid and currently it works on separate systems. Interconnection would allow areas to feed off of each other and make use of spare capacity.
I also think we need to harden the safety and security of our grids. The random attacks on them are very concerning.
Absolutely. Luckily this seems to be getting a lot of the right attention now. Need to utilize some of the Federal type security systems for much of the critical infrastructure.

Just an observation but using google as a search engine it is just about impossible to find any criticism or downside for solar or wind to solve climate change. Propaganda?
Settled Science?
Sorry, but REAL science doesn't work that way.

They do that to minimize misinformation. (sarcasm font)
This for sure. Not only from cyber attacks, but also from electro-magnetic attacks and for that matter, physical attacks.

Thank goodness I live in a state where we do not have any energy crises. How often do these occur?
GO NOLES!!!
Bonus:17 states will have outstanding viewing of the Northern Lights for the next week.
Is China sneaking military personnel into the U.S. via border? What we know
The House Homeland Security Committee chair has claimed to have evidence of Chinese men with "known ties" to Beijing's government and army entering the U.S.

A lot of conjecture and speculation in that article.Is China sneaking military personnel into the U.S. via border? What we know
The House Homeland Security Committee chair has claimed to have evidence of Chinese men with "known ties" to Beijing's government and army entering the U.S.
"Public data from the U.S. Customs and Border Protection (CBP) agency shows 2023 has seen a spike in encounters of Chinese nationals at the southern land border compared to the previous years—when border crossings were overall lower due to coronavirus pandemic restrictions."
"As of April, there had been a total of 9,854 encounters in the fiscal year-to-date, which runs from October to September, rising sharply from February. In 2022, there were 2,176 encounters."
"While over 1,500 of these were individuals in a family unit, the vast majority (8,304) were single adults—though a breakdown of age and what proportion are male is not given. Neither has the government publicly stated if any were believed to have ties to Beijing."
Not a whole lot of speculation there. Ill speculate though. If 10% of the 8304 are military age males that's 830 military age males from China just this year. Problem? Maybe not but certainly something to look into or we just figure they are here for the freedom.
No but its an indicator and increases the chances of them being one. Combine that with other indicators and you get a bigger picture. All this means is they (hopefully) would be screening these types and looking for ties to the CCP and other groups. Much in the same way you would look for a terrorist or criminal.
I don't disagree but that is the speculation and conjecture I mentioned previously.
What are your thoughts on why there’s a documented increase in Chinese males?
Chasing the bad guys after the bomb goes off doesn't work out too well. There is a degree of that in the process to connect dots but the article was pointing out numbers and a common infiltration tactic.
They could all be legit but chances are there are some bad actors there and chances are we dnt get them all at the border.
