Carbon neutral

The United States used 4,000 terawatts of energy in 2022. Industrial 32% or 1,280 terawatts Transportation 29% or 1,160 terawatts Residential 20% or 800 terawatts Commercial 18% or 720 terawatts The electrical grid is currently under stress because of the load and when windmills and solar panels replace power plants the distance from the source to the use point is much greater putting additional stress on the grid. If EV's take over the transportation power will be added to the grid. Even if enough new electrical power was generated to meet the goals the grid would not be able to move the power. To understand the enormity of the problem consider just one neighborhood where everyone is charging their cars at night during off peak hours. It would mean new power lines to each home and new transformers on all the polls. The current transformers use the night hours to cool down and that would no longer be possible. Multiply this by millions of neighborhoods and then add in all of the industrial usage and the entire grid would have to be upgraded and in most areas replaced. Then add in the electrical power needed to replace the heating of all homes and businesses that currently use natural gas. The answer is small nuclear power plants located near the use points and using the excess power to produce hydrogen which can be converted natural gas and diesel to power the transportation. EV's cannot do the job. Using hydrogen to produce natural gas and diesel is carbon neutral.
