That is a complete lie. Bio-fuels are here right now. We would be able to buy butanol right now if not for patents.
First, the resources required to create bio-fuels is enormous.
Yes, but most of them come from the sun, which provides the primary resource for free.
Second, bio-fuels will always compete with food for resources. Whatever it takes to grow algae, sugar beets, switch grasses, or whatever the favored bio-fuel of the day is takes the same land, water, fertilizers, etc. that food does.
No, that's a lot of shit. Algae does not compete with food crops for any of those things. You can grow it on dirty water or salt water and you can grow it in places not useful for food production, like deserts. You're ignorant.
Wind and solar power share many of the same problems that bio-fuels do in land, sun, weather, and so on.
No, in fact, they do not, and for the same reasons. You're ignorant.
Humans have only been able to rise above subsistence living once we've moved beyond wind, solar, and bio-fuels
We are not in fact employing any of these technologies to their fullest. What makes you think they cannot serve our needs? We have far more than enough land suitable for algae production in the USA completely unused for agriculture for us to replace one hundred percent of our transportation fuel needs with biodiesel-from-algae, using technology proven by the USDoE in the 1970s and 1980s which even includes carbon capture from fossil fuel plants. Granted, one hundred percent of our transportation fuel needs are not filled by diesel fuel, but Butanol is a 1:1 replacement for gasoline which you would be able to buy today if not for patents which should never have been granted on the basis of obviousness.
I fear that even with the most advance technology we can dream up cannot over come some real limitations to wind, solar, and bio-fuels.
That's because you're ignorant. We've discussed this.
With the promise that nuclear power holds I believe there really is no other choice, we cannot maintain our standard of living unless we move to nuclear power.
Again, that's because you're ignorant. We massively waste energy left and right. We do not mandate much insulation, nor other energy saving requirements. We permit companies to produce throwaway crap that cannot reasonably be serviced, at every level from pocket devices to major appliances. Simply eliminating a lot of waste related only to making it possible for already-wealthy people to get wealthier by enslaving poor people (typically by proxy) will save us vast amounts of energy. It's true that we must change our behavior, but we need not lower our standard of living. Only some people who add nothing to the system must do so, and they are a tiny minority of a tiny minority which have been taking advantage of the rest of us for literally millennia. There's no reason for the majority to care what happens to them. They're the class of people that go under the guillotine every few generations, and never soon enough.
If you're not ignorant, I apologize. I prefer to recognize shills. But a lot of the things you're saying are simply false on every level, and you should be ashamed at yourself for repeating these lies which benefit no one but those who are already very wealthy, and want for nothing save a conscience.
