Energy sources in Australia

 

 

 

 

Electricity in Australia

The common term is "renewables", but none of these energy sources is renewable. The sun, the moon's motion, and the heat in the earth will eventually run out. I'll use the term "clean energy"

Most of our clean energy sources have been in use for 50 or more years. Sugar mills burn bagasse, and hydo power stations were all built many years ago.

There has been a huge increase in wind and rooftop solar.

Cost of burning coal

 

Climate Spectator report:

Coal is not so cheap

 

A new economic analysis published in the highly prestigious American Economic Review has made a damming assessment of the costs of pollution from fossil fuel industries, and concludes that coal is doing more harm to the US economy than good – and that doesn't take into account its climate impact More.....

 

Pelletised biomass

From Climate Spectator

"First Biomass plans to invest in plants that make pellets from biomass waste – be it from timber or sugar cane plantations, rice, bamboo, hemp, or even olive pits - and then sell those pellets to biomass generation plants as feedstock. It won’t invest in generation plants itself.

The fund will include three pelletisation plants owned by First Climate – one in Brazil, one in Canada and one in the US – which will then seek half a dozen other similar investments. First Climate already owns nearly half of the pelletisation plants around the world. 

Biomass, although little known in Australia, it is the largest source of renewable energy in Europe, accounting for nearly two thirds of the renewable energy market, with around 800 terrawatt hours of energy production. In 2020, it is forecast to double to 1,600TWh, and still account for half of the EU’s 20 per cent renewable energy target, notwithstanding the much faster growth expected in wind and solar and other renewable fuel sources.

Several large generators are investing heavily in biomass, and replacing coal plants with biomass pellets. UK generator Drax intends to replace half of its coal-fired generation with biomass. But while biomass is considered to be “carbon neutral” when the feedstock is used from agriculture waste – and studies have shown that biomass and carbon capture and storage could even offer the potential of “emissions negative” energy production – environmental groups have voiced concerns when biomass production replaces food crops or forests."
