What I mean is I don't like how anything that is grouped into "renewables" is considered to be equally perfect.

In which case, you're projecting opinions on me which aren't correct.

In the world of energy sources available to humans, there are two classes:

Renewables which replenish given time.

Nonrenewables which don't.

For all of human existence save the past 250 years, we've depended virtually entirely on renewable resources. Which isn't to say they didn't have negative impacts on the land humans occupied. Deforestation and desertification are very common in human history and prehistory.

For the past 250 years or so we've had coal, oil, and gas. The chart looks roughly like this: https://plus.google.com/photos/104092656004159577193/albums/...

There are a handful of other nonrenewables which are sufficiently abundant that they might be able to address some of our energy needs (mostly electricity -- transportation, liquid fuels, and chemical feedstocks remain a major issue). They have some pretty tall technical challenges however. Thorium reactors are more probable, fusion rather less so: we've been unable to reach technical let alone commercial viability with 50 years' research during the period of maximum abundance.

And there's a very clear relationship between energy, economic growth, and population: http://ourfiniteworld.com/2012/08/29/the-long-term-tie-betwe...

Anyhow, as I said: list out your options. Figure out how viable they are, and what the negatives are.

A list of questions I like to keep in mind:

1. How Much Energy is Returned for the Energy Invested (EROEI)?

2. Have the claims been verified by an independent third party?

3. Can I see the alternative energy being used?

4. Can you trace it back to the original energy source?

5. Does the invention defy the Laws of Thermodynamics?

6. Does the inventor make extravagant claims?

7. Does the inventor claim zero pollution?

8. Can I see blueprints, schematics or a chemical analysis of how it works?

9. Infrastructure Requirements -- Does the energy source require a corporation to produce it? How will it be transported and used? Will it require new engines, pipelines, and filling stations? What will these cost? Who will pay for them and with what? How long will it take to build them?

Have fun.
