I would not invest in fossil fuel in a country that is heavily investing into nuclear power. Most of the costs associated with nuclear is in the constructions, so once they are built those costs are already sunk and they will deliver maximum energy at what ever price point that the market sits at. Fossil fuel can not compete against nuclear power on price after construction is completed, especially if paid by a budget a few governments ago. I would however consider fossil fuels as a great investment if a country is heavily invested in renewables. Someone has to operate as reserve energy for when the weather changes and the season change to winter. Politicians in northern countries has already demonstrated a great unity in spending a lot of subsidies on "reserve energy" plans. You do not even need to spend fuel to get paid. And then we the market price do rise above that of fossil fuel costs, you get paid again by producing energy at the point where the market is at its highest. It is hard to optimize more for profit than those operating a fossil fuel power plant in those reserve energy plans. The Swedish environmental minister last winter, who was also the spoke person for the green party, said something like: Oil power plants are and will continue be a natural part of the Swedish reserve energy plan. It is nothing abnormal to use oil when demand exceeds supply. It is hard to get a better political endorsement than that.
