Oh crap. I did not do judgement.

I put my judgment first though...... and i'm not quite sure about the others....

I didn't give definitions so yeah... I think i lost at least 2 marks there...

I basically wrote about everything...

Geothermal is good for the environment but australia doesn't possess the best hotspots to make it a viable resource. Nuclear power is the quickest way to lower co2 emissions but with the negative flaws of having a waste By-product which lasts for thousands of years... and to even make the uranium useable you would need to have more open cut mines etc..

Wind farming noise poullution and pretty useless unless wind is blowing properly 365 days a year... I also wrote about the fossil fuel plants being able to carbon store some sediments...

eg in a coal powered plant the sediment can be used as a good fireproof combination when combined with the right concrete.

It was very hard to do bad i think... you just had to know the main sources and how Australia is too reliant on them and our renewable energy portion is less then 20% of all sources of power.
