I'm doing research on Brazil and read that it's dependent on hydropower and ethanol produced from sugar cane as energy sources. Is ethanol bad compared to gasoline, in terms of environmental issues and safety? It's definitely better in terms of price. Anyways, any background info would be appreciated, since I've been having trouble comprehending articles on it.
It is not a bad fuel source. Ethanol has its advantages and disadvantages. Advantages includes (1) renewable, (2) zero net carbon and (3) available technology and infrastructure. Disadvantages includes (1) derived from Food related crop which raises prices readily (2) needs a lot of farm inputs which an cause soil degrading chemicals and large farm area for plantation (3) suseptible to weather changes. And there's a lot of other factors to consider. I just highlighted three. If you would tend to consider fuels bad or good at least you should have a guidelines set to qualify certain fuels as bad or good.
Sugar cane ethanol, the kind Brazil uses, is a good future looking source of energy.
Corn ethanol, the kind America has pushed on the world, is terrible. It is inefficient, raises every food price, and artificially inflates corn prices.
