There's a plethora of options. Wind, Solar, Hydroelectric, Wave, Nuclear
Yes, we should be transitioning away from gas, oil and coal for power generation, towards Wind, Solar, Hydroelectric, Wave and Nuclear. Many European nations have less than 40% of their power generation from fossil fuels and that quantity will only drop. France for example generates 95% of their power without fossil fuels i.e ZERO carbon. Of which 70% is nuclear.
Nobody likes their energy prices getting hiked by wars in the Middle East. Which you should be observing with electricity bills and your fill-up at the gas station. Maybe you're rich enough to not give a shit about energy/fuel prices, but I'm not and nor are most people in the world.
You think that all the multi-billion/trillion dollar petrostates and oil companies don't have a vested interest in perpetuating the use of fossil fuels for profit? Lmao.
If the world isn't being saved, its due to the myopic desire for oil barons to continue to make profit at the expense of the rest of humanity because they won't be alive in the future to deal with the consequences.
If we had genuinely tried with renewable energy over the last 30 years, instead of submitting to the bribery and political lobbying of oil companies and petrostates, maybe the world would be in a better position today. If most of our energy generation came from nuclear and renewables across the globe, perhaps the pollution and global warming situation would be acceptable enough to allow us our V8 toys. And that is what they are at the end of the day, rich people's toys.
