1. Coal,
2. Renewables (Solar, wind, perhaps ocean currents),
3. imported oil.
Coal should be deprecated already. Renewables are dependent on environmental effects, in particular solar doesn't work in emergency situations such as volcano eruptions rendering the sky dark. For oil, we depend on third parties, of which we know that they do not have our best interests at heart.
It is depressing to see the political situations on these metrics, especially the idea which gets pushed now, which claims that everything will be alright if we just optimize our energy consumption. It ain't gonna happen. People won't meaningfully reduce their energy-consumption, at least not in a way that would justify the use of fossil fuels.
So what are we left with? Nuclear is the only good bet you could make right now, while waiting out on fusion.
edit: I often think of this meme which goes around, talking about the fact that people are much more willing to donate to a single child in need, rather than a group of children who equally need help. People are prone to take action when they feel like their individual action makes an impact.
I feel like this is similar to the fossil fuels - vs - nuclear debate. We know, that about 20mil ppl die every single year due to air pollution. We also know, that a very small, countable number of people died of nuclear accidents, in the complete history of humanity, ever, in total.
Yet we seem to think that the few nuclear accident's fatalities are worse than the ones caused by air pollution. Why? Because we are in some way biased to give more meaning to individual events, rather than rates of change that are around us. And it'll break our backs if we don't carefully examine the problem at hand.
