    I believe you are correct, that the "absolute" value of emission is significant.

    In the chart, in the article, it says that "total production in Terra watt hours" in 2026 is now:

    • Coal: 140 TWh
    • Gas: 400 TWh
    • Nuclear: 180 TWh
    • Wind: 130 TWh
    • Solar: 60 TWh
    • Hydro: 70 TWh

    However, I am not sure how to interpret. This is because I have read that when electricity is created from gas, it is less efficient than when it is created from solar panel. This is due to burning being inefficient. So this makes the data wrong sometimes. Therefore, the data is confusing to me, because I do not know if this chart contains that information or if it is forgetting.

    If the chart is correct, then 1.1% increase in gas is about 4.4 TWh new gas. However, 23.9% solar increase is about 11.6 TWh new solar, and it is about the same for hydro. Therefore, overall, there is not as much new gas.

    I am reading about solar panel and renewable electricity in USA. It seems that there has been an 11.4% lowering of coal in the USA from 2025 to 2026, while at the same time there has been a 23.9% increase in solar panels and a 21.9% increase in hydrological energy. There has also been a 2.1% increase in wind, 0.9% increase in nuclear.

    The only negative fact is that there is a 1.1% increase in gas during this time. However, that is overall a 3% lowering of fossil fuels in 1 year. It seems that the coal is being replaced almost entirely by renewable energy, and a tiny bit by gas.

    There is so much new solar panel electricity that even despite all the AI data centers, they are using renewable electricity for new buildings, and very little gas for new buildings. Therefore, I do not worry about the AI electricity, because I believe the solar panel and battery will be enough.

    Overall, fossil fuels continue to generate about half the electricity put onto the grid, a figure that doesn’t change when you account for small-scale solar projects that produce power that never appears on the grid. The three major renewable technologies accounted for more than a quarter of the total. When nuclear power is also considered for emissions-free electricity, the total exceeds 45 percent.

    The most notable thing about the trends in generation is how they are roughly the reverse of the Trump Administration’s priorities. Despite multiple attempts to block its development, renewable power continues to grow, and wind is likely to benefit from the opening of the US’s first large offshore wind farms in 2025 and 2026. Meanwhile, coal is dropping even as the administration is ordering plants to stay open past their planned closure dates.

    So even though Trump (stupid idiot) is trying to stop all solar panel, he is failing. This is because solar panels are very good. I see that Trump is very evil, but it seems that he is too stupid to be efficient at being evil. Therefore, the good society and electricity scientist is winning.

    I am very hopeful for all USA electricity to be clean in the future. Once all electricity is renewed, I am hoping that they will make all cars use electricity. I have read about Tesla Semi Truck for this. However, I would like to purchase small car that is electric, but that is not a sport car (expense). I am hoping that they will allow China's cars into USA so that I can purchase cheaply. However, I will also purchase USA-made car from Detroit that is electric if it is cheap.

    I have read about China installing solar panels for new electricity needs. However, now I am reading about India. Although they were installing many coal power plants in the past, now, they are installing renewable power plants.

    Installed solar capacity in India has been growing by 40 percent a year. In March, it passed 150 gigawatts, and by 2030 is set to double again.

    Ever since the Glasgow conference, India has been introducing solar energy at an accelerating rate. Last year, for the first time, more than half its installed generating capacity was from non-fossil fuel sources.

    As booming India’s electricity demand continues to grow by more than 6 percent each year, the solar trend is set to continue. According to the International Energy Agency (IEA), about half the growth anticipated between now and 2030 will be met by solar power, and another 25 percent from other low-carbon sources, mostly wind, hydroelectric, and nuclear.

    However, there are still many coal power plants in India. This is because they were built when solar panel was expensive. However, now that solar panel is cheap, India will stop building new coal.

    India still has a long way to go to break its dependence on fossil fuels. Coal still delivers most of the country’s baseload and fuels about 70 percent of total power generation. It helps make India the world’s third largest carbon dioxide emitter, after China and the U.S, and is a major cause of the country’s urban smogs, which are the worst in the world. But the target to double coal mining output has been quietly forgotten, and construction of coal-fired power stations is much reduced. Coal’s share in the energy mix is set to fall below 50 percent by 2035, according to the IEA.

    It seems the problem is that India must build electricity power lines to transmit the solar panel electricity into the factories, and they are investing funds to do that. However, it seems that they are also starting to be using battery to store electricity.

    Starting later this year, a 1.4-gigawatt project is expected to pump water from one of India’s largest hydroelectric reservoirs, the Gandhi Sagar on the Chambal River in the state of Madhya Pradesh. Another, with a capacity of 3 gigawatts, is set for completion near Mumbai in 2030. In January, the country’s Central Electricity Authority identified 120 potential pumped-storage sites with a combined capacity of 180 gigawatts.

    Another solution to the storage problem is lithium-ion batteries. World battery prices are falling dramatically — down 58 percent since 2023, says Ember’s global electricity analyst Kostantsa Rangelova, “making round-the-clock solar electricity increasingly viable.”

    I have read that the cost of battery is lowering very rapidly. I believe that this will continue due to innovation in technology. Therefore, I believe that the reality may have faster installation of solar panels and battery than the predictions say.

    I have found another article that says there is still solar panels being built in USA. However, it is less than elsewhere. Trump is making stupid decision for the country. This is because he is a bad businessman (not smart). The solar panel is more profitable, and yet he still invades Iran to get gasoline.

    Trump could corruptly install solar panel and make much money. However, he corruptly uses gasoline which is bad investment due to air pollution.

    Globally, combined wind and solar output ​is estimated to have grown 13% ​year-on-year, with ⁠gains in several markets including China (+14%), the European Union (+13%), Britain (+35%), the United States (+8%), Australia (+17%), Chile (+24%) and Brazil (+4%).

    Most important, is China, which is very large county, very polluting. However, it is important for all the countries.

    Solar panels and wind turbines are generating over 2x as much electricity as they were 5 years ago. Now, they are generating so much electricity that it is more than gas power plants. Therefore, there is less polluting chemicals in the air.

    A recent analysis shows that April 2026 marked the first time globally that electricity generation from solar and wind exceeded that from gas. The two renewable sources accounted for 22% of global electricity generation, while gas-fired power plants supplied 20%, or 531 TWh compared with 477 TWh.

    Five years earlier, in April 2021, gas-fired generation stood at a similar level of 476 TWh, according to Ember, but was nearly double the combined output of wind and solar, which totaled 245 TWh.

    The article says that April is the most likely month for this to happen. Therefore, society must build more solar panel and wind turbine to repeat this in future months. I believe it is possible due to the lowering cost of solar panel and battery. In the future, renewable will defeat gas power for 1/2 the months, and then every month.

    However, Trump is stopping this in USA because he is a stupid. I believe rest of world will build enough solar panel and USA will use gas until it realizes it is becoming poor. Then, USA will use more solar panel. However, maybe states in USA will install more solar panel despite Trump. However, it requires the permits to build the solar panel and many of the counties are banning this. Therefore, citizens must vote for county to build more solar panel.

    One day, there will be only solar panel and wind turbine, and geological energy. Then, there will be no gas power plant (smelly) and air will be cleaner. Therefore, it is better for stopping asthma in the children. Also, it is better for plant and animal because there is no pollution.

    Powerplants are just doing centralized internal combustion. Emissions may be lower because centralized, but then you also have line losses.

    Some of the power plants are combustion, and some of the power plants are solar panel. Therefore, on average, the total power plant electricity emission will be less than combustion emission on trucks. I speculate, but I think that the power line does not lose enough energy to defeat that.

    What is the reason to use methane garbage trucks? The gas explodes and pollutes the air.

    I am not sure if the price for batteries at the home are as low as the batteries for the power plant. However, it is possible. Perhaps it is different in every country and state. For example, I believe Mr. Viking is from Australia, where it is very sunny. However, in cold places, perhaps it is less economical.

    But I believe that it could be useful to have batteries for the home no matter what. If there is enough energy for plants, then there is enough energy for solar panel, in my opinion. Also, if there is a large storm that breaks the power lines, the batteries could provide electricity before the repairing. However, perhaps this depends on the configuration.

    If you have many acres of land, then it is possible to install solar panel on the ground and rotate with the sun. Otherwise, the solar panels on the rooftops are still effective.

    I have read this article in NY Times about Tesla 18-wheel trucks that are electric.

    After years of delays, Tesla has begun taking orders for the Semi, which is expected to cost around $290,000 for the version that can travel up to 500 miles on a charge, much less expensive than heavy-duty electric trucks sold by Daimler, Volvo and other companies, which usually sell for at least $400,000, according to estimates by the International Council on Clean Transportation. Tesla has said the Semi will also have a more affordable model that can travel 350 miles between charges. Both options would travel farther than trucks from other suppliers.

    Demand for the Semi appears strong. California trucking firms have asked the state government for subsidies to help them buy more than 1,200 Tesla trucks. That’s more than all the applications for other electric trucks since the state’s incentive program began in 2019.

    Because the truck is electric, it is better for the environment.

    If Tesla can push the trucking industry toward battery power, the environmental implications could be significant. Heavy- and medium-duty diesel trucks make up a small percentage of all U.S. vehicles but are responsible for 45 percent of nitrogen oxide emissions from road transportation, according to the Union of Concerned Scientists. Nitrogen oxides cause asthma and bronchitis and are the main component of smog.

    Also, it is better for the driver.

    Mr. Torres said the Semi was quieter than diesel rigs. And he can run the air-conditioning while waiting to drop off a load. That is sometimes not possible with diesel trucks because California limits how long those vehicles can idle in residential areas or near schools and hospitals to minimize pollution.

    I hope that Tesla will sell many electric trucks so that all the diesel trucks are replaced. I do not like the diesel trucks because they are polluting and the exhaust is unpleasant to breathe.

    I have seen in this video from Mr. Ferrell, that the cost of installing the solar panels is $16000. I am wondering why that can be so expensive? I see that it may be complicated on some roofs. However, for a simple roof, I am not sure why a homeowner cannot just do it alone, without paying contractor. Myself, if I were installing solar panels, I would ask my niece's husband to help and give him $200. Unless there is a technical requirement that is very challenging without a professional?
