There are plenty of good hard-working honest people in the oil business just like in any other business. Fossil fuels supply more that half U.S. energy, energy for heat so that people don't freeze, energy for hospitals that save lives. Come up with a cheaper cleaner product instead of deciding to "dethrone" those who don't agree with your opinions.
Lazard, an independent invesment bank, produced a levelized cost of energy per megawatt hour (LCOE per MWh) estimate for the US in 2020. Here are the price ranges (including US tax credits but excluding carbon pricing) and average annual price:
Utility PV - $24 to $42, mean of $37
Wind - $9 to $43, mean of $40
Natural gas combined cycle - $44 to $80, mean of $59
Geothermal - $49 to $94, mean of $80
Nuclear - $125 to $200, mean of $163
Natural gas -$142 to $206, mean of $175
Coal - $61 to $164, mean of $112
Residential PV - $135 to $205, mean of $141
Here are the International Energy Agency's estimates of global levelized cost of LCOE per MWh for 2020
Onshore wind - $31 to $41
Offshore wind - $71 to $110
Home scale PV - $16 to $227
Utility scale PV - $39 to $61
Hybrid source PV- $47 to $58
Geothermal - $36 to $72
Coal - $41 - $159
Natural gas - $51 - $107
Heavy oil - $91 to $131
Natural gas combined cycle - $28 to $127
Ultra-super critical coal - $41to $78
Generally speaking, utility scale solar and onshore wind are the cheapest forms of electricity, typically around 1/2 to 1/3 of traditional fossil fuel power.
Advanced combined cycle turbines is about the next cheapest, but only for a few markets. The LCOE for combined cycle gas is typically only competitive in countries with abundant and cheap natural gas.
However, renewables prices continue to trend downwards, while fossil fuel prices continue to trend upwards.
