One Webpage per Topic or splitting up for better reading...?

What is better from a SEO-Point of View:

I am building right now a website where the principal topic is Renewable Energies.

There will be a menu listing all kinds of Energy-types:

• Biogas
• CSP
• Biomass
• etc.

And now my question: Each Topic has about 800-1000 Words of unique content with sub-topics. I think its certainly good to have for each energy type one separate page. But I think its no a good Idea to split also the subtopics up to further sub-pages like:

• www.energy.com/renewable-energies-biomass.html
• www.energy.com/renewable-energies-biomass-eficiency.html
• www.energy.com/renewable-energies-biomass-market.html
• www.energy.com/renewable-energies-biomass-industries.html

as 1000 Words on one page may look like better higher quality content than making 3-4 pages with just 200 Words... talking about Biomass, but from several points of views.

So I think its better to put all about Biomass on one single-page and use a menu just to jump to the subtopics via anchor-tags.

Right?

Thanks Kate and Charles!

Meanwhile I found out whats the right term for my question: "Pagination" I read about using the rel="next" and rel="prev" attribute when paginating an article over different pages.
MY DOUBT: Sometimes you see single page paginated by using javaScript that hides text although all is in the page source, for better reading. Does Google like that or might think it could be hidden text with spamming purpose?

So I think using old school "named anchors" to divide text into topics (for text about 1000 words) is better than using javaScript that reaveals text via pagination or expand collapse.

First, don't worry so much about how much content is on the page. You should format your pages based on what works best for what the searcher is looking for. If there is demand for information on Biomass Industry types and there is enough content for a page, then create a separate page. If there isn't enough content for one of these pages, and it makes sense for the user to land on the more general page, do that.
