Modelling produced for the report suggests that by 2050, up to 45% of Australia’s electricity supply could be provided by millions of distributed, privately owned generators, in homes and businesses.

Oh, modelling.

Are you a licensed broker? Is this a Ponzi scheme?

"The company Bakers Maison will pay investors for the solar energy it uses over a period of between seven to 10 years. The investors get a 7 per cent return on the money they put in."

You notice they don't say 7% pa?

They recently converted their oven from electricity to gas.

"Consistently investing in strategies that minimise our carbon footprint, we most recently converted our ovens from electricity to gas and installed over 1,000m2 of solar panels to allow us to generate our own electricity. "

You do understand the written word; don't you? The ABC are the ones who wrote it. Complain to them.

"They say, by 2050, Australia could have zero net emissions but a price on carbon would be essential."

Read subsidies.

"It would require 25 new large-scale solar or wind farms in the next five years to replace coal-fired power stations."

What would e the footprint of these solar farms?

"Millions of home battery-storage units would also be needed."

So they need millions of homes to have solar as well as these large scale solar farms.

"The report suggests around 40 per cent of energy generation could come from such renewable technologies in the eastern states by 2030 and easily replace coal-fired energy."

How about the other 60%?

Perhaps you need to look at the numbers. And of course they are doing these installations with subsidies. Didn't you say energy companies should be paying? They are the ones on the receiving end of the subsidies.

So why invest in something that is intermittent? Requires large land areas that could be put to better use?

very good. Now about cleaning dust off solar arrays in the desert. What would be the cost? What time of day/night could the cleaning take place? Deserts are generally remote.

"The small-scale solar PV market recovered late in 2016 to post a 1.3% increase on 2015 installed capacity. Solar PV systems equivalent to 723MW were submitted for creation during 2016, compared to 714 MW in 2015."

About those numbers?

I have stated before that I don’t think solar baseload is practical. Solar is good for remote communities, cheaper than diesel, good for rooftop solar on homes, offices etc.

Tidal (yet to be really developed) and geothermal (SA possible) and wind are the most promising baseload renewable energy sources with hydro—better to set up another Snowy Mts Scheme in Qld than try largescale solar.

An ultra high voltage DC grid can connect the various major renewable sites together so there is always renewable power being generated somewhere.

And nuclear for heavy loads for industry.

But we do need to decarbonise the economy.
