Renewable Energy Sources

Which is the best renewable energy resources. Some examples are wind, solar, wave, biomass, geothermal, tidal, hydro-electirc, etc. It doesn't have to be listed...if it is renewable go for it.

I have always been a huge fan of Algae Biofuel. The advantages are staggering. Algae doesn't cut into existing food supply, it uses extremely little land to grow, it yields very high energy output (about 4 to 10 times as much as corn ethanol), doesn't require pesticides or fertilizers, it can be grown just about anywhere, it doesn't produce greenhouse gases but actually absorbs existing CO2. The only real downsides are that it uses a lot of water and light to grow and the technology is not yet fully developed.

They're developing artificial photosynthesizers right now, and the generated energy would be direct too. The only real problem is getting past the 30% efficiency limit, but I'm sure they'll find the right compounds soon.

Not fully developed? This idea has been around since the 60's, no? Boy, have we got our priorities sorted.

Well, if we end all government subsidization and regulation, the evil, greedy corporate war-mongers will just use the blood of the innocent... along with oil... that's not subsidized...

WAVE ENERGY!!!

I don't know why more investments aren't being made into this. Over 70% of the earth is water, yet no one has considered harboring it's power. Almost 1,000,000,000 people love near a coastline. Wave energy is the future!

Turbines in the water that turn with the flow of water. There are very few drawbacks (the most significant being noise).

That is all.

Sure, until a great white bites into a turbine and is struck by lighting during a storm and mutates into a super shark which breads with narwhal and the hordes of offspring learn to walk with hybrid water/oxygen lungs and take over the earth... fuck that. I don't want work in a Great White Narwhal mine digging up their precious nephrite and jadeite just so they can use it as conductors in their human mutation experiments creating an army of zombies with the sole purpose of eating our brains when we don't dig up their nephrite and jadeite fast enough. Zombie or slaving away in Great White Narwhal mines Apollo, which part of wave energy do you like better? Because that's what you're trying to damn humanity to ._.

"WAVE ENERGY!!!"

Yes, in theory it has considerable potential.

"I don't know why more investments aren't being made into this."

Simple, its a massive risk that isn't worth taking for most investors.

"Over 70% of the earth is water, yet no one has considered harboring it's power."

No, many people have been considering harnessing it's power for a long time, as with all issues of this nature it is highly complex, nuanced, and cannot be expounded by resorting to simple either/or propositions.

The incentive to develop wave energy (thoroughly) just doesn't exist yet, even in my country (which has considerable wave energy harnessing potential) money is being poured into wind because the technology is mature, and if exploited correctly is proven to provide a highly favourable energy balance. This cannot yet be said of wave energy.

"Almost 1,000,000,000 people love near a coastline"

It doesn't matter how many live near the coastline, the infrastructure has been designed to accomodate those people, it hasn't been designed to accomodate wave energy.

"Wave energy is the future!"

Maybe, it's definitely part of the future (i.e. it will inevitably be part of the fuel mix used to satisfy future demand), and it will inevitably start to play a much bigger part in powering society as the technology matures, but the jury is still out.

I think it will be a long time before it becomes one of the more commonly exploited forms of RE, if ever.

"Turbines in the water that turn with the flow of water."

Actually, the best mechanism (referred to as as the power take off system) for extracting KE and producing mechanical power is (still!!!) up for debate. It isn't like wind energy in which a concensus has been achieved on it's optimum design. Standardisation is one of the most important steps in making a technology commercially viable.

"There are very few drawbacks (the most significant being noise)."

There are many drawbacks, most notably with O & M which raises a plethora of technical issues which all serve to increased the the risk asscoiated in investing in the technology.

If you like I'd be happy to discuss further the relative merits and demerits of the technology.

And this is true for most other renewable sources, as well.

And I don't understand why considering how expensive it is compared to coal/nat gas, etc.

It doesn't matter how many live near the coastline, the infrastructure has been designed to accomodate those people, it hasn't been designed to accomodate wave energy.

I meant that more as a personal hope than a declarative statement.

Standardisation is one of the most important steps in making a technology commercially viable.

I believe this will have to change if we are to optimize energy production. Diversification of sources is almost inevitable, in my opinion.

This is because of a lack of research and investment, not limits of the technology itself.

I think either wind or solar would be good because they first of all don't cause global warming and they can be put anywhere and they are cheap.

Side: wind and solar

I think renewable batteries are the best source. You can recharge them over and over again.
