The program is not functioning correctly
The program is not working properly. If you wanted to power the entire Earth with solar power, I estimate you would need around 112,000 square kilometers of at least moderately efficient photovoltaic panels. That sounds like a lot, and it is, but it’s also not because those panels could fit into just a little more than 1% of the Sahara Desert. With the falling cost of solar panels, it could be done much more cheaply than making the same amount of power with nuclear fuel.
However, there is a big problem with relying on renewable resources like solar and wind: what happens to our electricity when the Sun goes down? Sometimes the rotation of the Earth can be a real bummer. To solve this issue, we need reliable ways to store and transmit electricity so that it’s available when and where we need it. This will require a lot more technology and a lot more space.
The amount of electricity a neighborhood uses varies during the day depending on people’s habits. In the morning, people get up, turn the lights on, make coffee, and watch YouTube videos, causing the load on the electric grid to gradually ramp up. After that, things tend to stay pretty constant during the day. But then comes the evening, when people are coming home, turning on more lights, cooking food, playing music, and chilling. To avoid overproduction, utility companies do something called curtailment, where they selectively switch off solar panels or wind turbines at their most productive times.
