Biomass

Part of the rice husk process

Another idea for generating energy is to use any organic material  - lunchbox scraps, fallen leaves, wood, straw, manure - because it all has energy from the sun, captured during photosynthesis, stored in it. 

When these materials are burned they release the energy, and now we can process them to make liquid or gas fuels.

Take a look at this Green TV story about a village in India using rice husks to fuel its power station.

Fuel or food?

One concern about biomass is that some people might be tempted to use farming land to grow crops for fuel rather than food.

This could leave the world short of food to feed its 7 billion people (and growing!).

A solution may be a desert plant - agave - which doesn't need fertile soils or much water! 

Seaweed - what an idea...

Another source of biomass could be seaweed. That certainly wouldn't take over farmlands!

Scientist have just discovered how to use a microbe from the human stomach to break down sugar-rich seaweed to allow efficient energy production.

Algae...enormous potential!

VERY exciting developments have been made by Queensland research corporation Stanwell.

A trial caught the carbon dioxide from a coal-fired power station (which usually goes straight into the atmosphere) and pumped it into water to grow algae.

The algae grew very rapidly - doubling in mass almost every day.

Not only was the carbon dioxide diverted from the atmosphere but it fuelled the growth of the algae which can be used to feed cattle or make biofuel.

You can read more about that development in the link.

We asked Australian students to make a video or convince us in writing about their BIG ideas for a sustainable energy future.

Check out the fantastic videos we received, all about sustainable energy solutions!
