About 100 billion dollars.
Power is distributed through what is called the grid. The grid is a system of transmissions lines that all major power sources are connected to. This allows us to send power throughout the USA. The downside is that this grid is terribly power hungry. It consumes tons of power that we could save if power was generated locally.
yes it can be used because power grid frequency is same
About 19% of the electricity used is from nuclear power, but all the lower 48 states of the United States use some nuclear power. Alaska and Hawaii are separate. Electrical power is conducted on a grid. The power goes into the grid from various power stations, and is used by various users. If a power plant goes down, the grid distributes power continuously because other plants continue and take up the slack. There are not many people who can say their power comes from a specific power plant, and most of those are probably off grid users (people who generate their own power). One estimate is 180,000 families, which might be 900,000 people, are off grid. In addition, roughly 700,000 people who live in Alaska and 1,300,000 in Hawaii have power that does not come from nuclear plants. That totals about 2,180,000, or about 0.7% of the population of the United States who use no nuclear power.
In Europe and in northern Japan 50 hz is used. The US has a 60hz system for its' power grid.
You mean electric power? Yes; it goes both ways. The US sells power to Mexico and also purchases power from Mexico. One example is the San Diego-Tijuana power grid, which is shared among both countries and is part of the larger Southwest grid, serving the US states of California and Arizona, as well as the Mexican states of Baja California and Sonora. All four states were impacted during the "2011 Southwest Blackout"
The US helped rebuild western Europe with the Marshall Plan.
So U.S. electric companies can make lots of money supplying power to Canada when they shut down their nuclear plants because wind and solar will not support the demand.
The power grid in most areas is 220 volts and the TVs have different settings
We won't know until you let us see the grid.
how to use a map grid and that it helps us find exact locations
helped them rebuild
The US often provided funds and materials to help rebuild what was destroyed by the war, but the US also stayed in countries to help them rebuild - possibly restructure - the governments.
