The deeper you go, the hotter it gets. Away from tectonic plate boundaries, it is about 25°C per km of depth (1°F per 70 feet of depth) in most of the world, so four km deep the temperature is around 100°C, which is good for producing steam.
The depth to the water table is the distance from the ground surface to the top of the saturated zone. The depth of a well must be drilled below the water table to ensure water can be extracted. The well should be drilled deep enough to reach the water-bearing aquifer but not so deep that it goes below the water table.
The depth of well water can vary depending on the location and type of well. It can range from a few feet to several hundred feet deep in some cases. The depth of the well water is typically determined during the drilling and installation process of the well.
An oil well is usually drilled into underground rock formations, such as sedimentary rock, where oil is trapped. The well is drilled deep into the earth to reach the oil reservoir and then oil is pumped to the surface for extraction.
The main limitations of geothermal energy include the high upfront costs of exploration and drilling, the limited availability of suitable geothermal sites, and the potential for reservoir depletion or cooling over time. Additionally, there are environmental concerns related to the release of greenhouse gases and other pollutants during geothermal operations.
Drilled oil wells are significant as they allow for the extraction of crude oil and natural gas from deep within the earth's crust. This extraction process is essential for meeting global energy demands and has a significant impact on the economy and environment.
That depends how deep the well was dug or drilled.
it can cause small earthquakes if i is not drilled right

I think you refer to an Artesian well.
It is difficult to say. There are many forms of renewable energy (solar, wind, hydro, tidal and wave, geothermal among others) and some are easier to set up than geothermal. A geothermal power plant requires two shafts drilled deep into the earth to get hot water and steam for the plant, and wind and solar may be an easier answer for the future.
The depth of the water table determines how deep a well must be drilled to reach groundwater. Wells need to be drilled below the water table to ensure a consistent and sustainable water supply. If the water table is deep, wells will need to be drilled deeper to access the groundwater.

It's the other way round. Geothermal power creates steam. Water is pumped deep underground where it is forced through layers of very hot rock. The steam produced is pumped up another shaft where it is used to spin a turbine, generating electricity.
The first oil wells were drilled in China in 347 A.D. using bamboo poles. In Persia hand dug wells reached depths of 115 feet in 1594. The first modern well was drilled in Russia in 1848, and in 1859 Colonel Edwin Drake drilled the first US oil well for commercial oil production, at Titusville, PA; it was 69 feet deep.
