This week we looked at all types of energy and fuel sources, some renewable some not.
Renewable energy sources are a pretty important topic at the moment with global warming being such an issue. At the moment most energy sources are non-renewable, like coal, this means that as we use them we cannot replenish them, so one day they will run out. We are slowly changing to renewable energy sources, this means they will never run out and we can continue using them forever. One of my favourite energy sources that we researched is the idea of converting our waste into energy. About 80% of Australia’s waste is available for the production of energy. The conversion will reduce green house gas and fossil fuel emissions. Unfortunately waste can be difficult to process and transport. Conversion plants may also have to be far away from rubbish plants, although this should be easy to fix. Converting waste to energy is not a very nice sounding source for energy but it is practical because of the way we live. Ethanol is another plan for resourcing energy. Ethanol can be created from many plant forms, making it very diverse and possible to be created in many places. Unfortunately as Ethanol relies heavily on the crops of plants used to create it a bad harvest will result in a shortage of Ethanol. The creation of Ethanol is relatively easy and does not release many Co2 emissions. Wind power is also one of my favourites, it is not highly favoured as the wind turbines are impossible to hide away in the middle of nowhere and forget about. Some people think they remove from the natural look of Australia’s coastline, but I think they enhance the look. Some people complain that they will kill birdlife off, but if a bird flies into a wind turbine and dies it doesn’t deserve to live as the turbines are extremely slow moving. They release no emissions and are powered by a source that does not require changing to be useful.
There are many options out there for Australia and other nations, each have their own positives and negatives.

Good sum up of your favourite alternative energy sources. Good reasons for all of them. You showed a clear understanding of the concept of renewable vs non-renewable.
