Processing, mining, and waste disposal is expensive.
The reason that oil shale is not used to produce oil is because this is what keeps the oil well from collapsing after the oil is removed. If the oil shale were mined, the oil well would collapse into a large trench in the ground.
Solar and wind renewable energy, of course. Oil shale and tar sands
You don't make oil from shale, you extract oil from shale. The shale acts like a sponge, sometimes the shale is so porous that the oil can be squeezed or sucked out, otherwise it can be extracted by crushing and heating the shale.
Apart from burning fossil fuels (coal, oil and natural gas), we produce electricity from renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass, biofuel and hydrogen).

Fracking itself does not produce energy. It is a method used to extract oil and gas from underground rock formations such as shale. The energy produced from fracking comes from the oil and natural gas that is extracted through this process.

The mining of oil shale requires the extraction of kerogen, a solid organic material, from underground deposits. This involves surface mining or in-situ extraction methods that can be energy-intensive and cause environmental impacts such as land disturbance, water use, and production of greenhouse gases. The extracted kerogen must then undergo a retorting process to produce shale oil.
Perhaps your question should be rephrased as: Is oil shale better than crude oil. My simple answer is: Not necessarily. The oil shale is correctly termed kerogen or "unmatured oil" that has been trapped in shales. Extracting and burning oil shales (rock + kerogen) is a low grade fuel (see related link) so I would not consider this better than a good grade crude (Sweet Texas crude). The transformation of the kerogen to a synthetic oil, which frequently is not better than common grades of sweet crude. For example, if there is high sulfur content, then market price may be lower than Texas sweet crude. Also, a complicating factor for refineries is the arsenic content, which comes from the retorting process, and would reduce the market price of the synethetic oil. As discussed in the related link, some of the lower gravity synthetic oil may be used to produce jet fuel or kerosene. The general rule that no two oil reservoirs produce the same crude, applies to synthetic oil from oil shale, but it is more complex as it depends on the kerogen present in the formaion and manner in which the kerogen is transformed into synthetic oil.

Shale oil is an oil distilled from shales and used as fuel
The oil thermal plant refers to the chemical energy that is stored in the fossil fuel like the natural gas, oil shale, fuel oil, and coal. They are usually successively converted into thermal energy, mechanical energy, and electrical energy.
Oil shale is not classified as a renewable energy source because it is a fossil fuel that is formed from the remains of marine plants and animals over millions of years. While it is abundant, it is not considered renewable due to the length of time it takes for oil shale to form.
