Personally, pretty lousy and thanks for asking...oh, you didn't.
But I am talking about how your electricity is generated. Australia has a mix of generation and fortunately we have never had a Chernobyl, Three Mine Island or Fukushima as we don't generate electricity by nuclear reactors. Long has our general population been against nuclear, in spite of such being pushed by vested interests. The Nuclear Disarmament Party was very active in Australia and took no prisoners of either the Labor Party or the Liberal (conservative) Party.
Our electricity is predominately generated by black coal, while my state of Victoria's electricity is mostly generated by burning dirty damp and polluting brown coal. But we do have hydro electricity in two eastern states and the island state, Tasmania. Tasmania's electricity is dominantly by hydro, but some environment was destroyed in the process to build retaining dams.
Generally our power generating assets were sold by governments to overseas investors who are not there to provide a service but to make profits. Who knows who owns the poles and wires. Who knows who your wholesale power company is which is different to your retail power company. But the system is actually quite strictly controlled by authorities, especially the NEM and in my opinion it works reasonably well.
The problem for these overseas investors with our coal power plants is their age and their polluting factor. Our conservative Federal government, wanting to protect investors in the dinosaur generation business, is encouraging them to invest in new 'clean and green' coal and gas power plants. They don't pollute too much, just a bit.
But our pro capitalist conservative government has been overtaken by capitalism.
Solar panels on rooves, wind farms, solar generation are all generating so much power they are making our power system unstable. Capitalism again kicks into action, starting with Elon Musk's big battery in South Australia to store renewable power. There are plans for storage batteries in every state.
Our dinosaur Liberal Party needs to get into step. Coal and gas power generation will soon be history. There won't be anymore wilderness areas flooded to make hydro dams. In the longer term oil powered cars will be history, so a wise investor would steer clear of oil.
You can add to this that our home appliances and no doubt industry machines have become much more energy efficient. All those LED lamps replacing incandescent, fluoro and 250 halogen bulbs per two storey McMansion must make a difference.
My generation may have screwed up many things but we have at least left this still up in the air but very foreseeable environmental result of renewable power at a very cheap price.
