FWIW - the types of incentives given to oil and other fossil fuel companies are very different from the types given to "green"/renewable companies.
For example, an oil company receives incentives in the form of accelerated tax treatment. The oil company can write off (deduct the cost against profits) the cost of a well in a period of a few years versus the life of the well. The purpose of this treatment is to allow the oil company to recoup the well's cost faster, and this allows the oil company to then sink more wells. The the oil company sinks more wells, and this increased production benefits the oil company (more profits) and the consumer (lower oil prices). This approach is also revenue neutral for the government/tax payers. The oil company pays the same amount in taxes over the life of the well presuming a constant tax rate - less tax paid in the early years followed by more tax paid in the later years versus a level amount of tax paid during the well's life.
Electric cars and home solar systems are given very different incentives. The purchaser of an EV or home solar system receives a tax credit (a loss to the government and tax payers that is never recovered). The tax credit only benefits the purchaser and seller of the item. In terms of societal benefit, you would have to argue that having EVs and home solar systems reduce demand for oil and electricity, and then you have to claim that this reduction reduces the cost of oil and electricity. However, these arguments are flawed. Using a home solar system as the clearest example, a home solar system does not reduce the power company's need to build generation stations. The power company has to have enough generator capacity to meet demand 24/7/365 within seconds to avoid a grid failure (days or weeks to reset); and therefore, the power company has to build to full capacity regardless of any fickle source (rainy day for solar, calm day for wind and etc.). The "green industry" incentives are a direct transfer of money (tax payer dollars) to the buyers and sellers of EVS, home solar systems, wind mills and etc. with no direct societal benefit.
