Climate clippings 221

I’ve just noticed that last September I followed CC 214 with CC 115. My bad.

1. Solar, wind and hydro could power the world, at lower cost

That is according to an updated study by Stanford University professor Mark Jacobson and colleagues at the University of California at Berkeley and Aalborg University in Denmark summarised by Giles Parkinson.

    it lays out three different methods of not just providing 100 per cent renewables for electricity, but also for heating and cooling, for transportation, and even agriculture, forestry and fishing.

Australia puts the brakes on wind

Wind power, seen as inherently evil by our national government, was in danger of taking over in South Australia. So something had to be done to slow it down, right?

How about if the wind blows strong providing cheap power we mandate that the gas must be turned up as well, so the wholesale price goes up instead of down?

It seems absurd, but that is what has been done. Continue reading Australia puts the brakes on wind

Energy crossroads

Transformer over orange sky
The initial stimulus for this post was an article in the AFR entitled We are at an energy crossroad (paper version) by Tony Wood of the Grattan Institute, based on a new report Powering through: how to restore confidence in the National Electricity Market and a series of articles mainly at RenewEconomy. I’ll summarise them Climate clippings style, so the story should emerge and you can follow the links for elaboration if you choose. Continue reading Energy crossroads

1. Murdoch media continues the energy wars

The Murdoch media continues to lay the blame on renewables, a notion specifically rejected by AEMO, leading to a Twitter battle between SA minister Tom Koutsantonis and The Australian’s Adelaide bureau chief, Michael Owen.

2. AEMO embraces change in the SA blackouts report

1. Global plan to save 10 per cent of coral reefs

A world-wide plane is being hatched a global plan says only 10 pc of coral reefs to save 10 per cent of coral reefs. The stark fact is that:

    Scientists estimate 90 per cent of the world’s coral reefs will disappear in the next 35 years due to coral bleaching induced by global warming, pollution and over-development.

The 50 Reefs initiative, recently launched at the World Ocean Summit in Bali, in a donor funded initiative to identify the 10% of reefs most likely to survive past 2050. Effectively it’s a triage operation. Continue reading Climate clippings 197

Gas, pumped storage and energy futures

Craig Emerson says we can get the gas we need, but is it necessary?

Craig Emerson has an article in the AFR, also on his site, suggesting that politicians need to urgently turn their minds to gas supply in east Australia. Emerson had warned them back in 2014, but they took no notice, and AEMO assured everyone there was no problem.

Suddenly there is. The price of gas-fired electricity threatens manufacturing jobs, and gas is needed to replace coal-fired power. Continue reading Gas, pumped storage and energy futures

Renewables under attack – again

wind-farm-hero_250The Coalition government and the Murdoch press were already mounting a full-scale attack on renewable energy when the AEMO report on the SA blackout presented information in such a way as to cast further doubt on renewable energy. AEMO stands for Australian Energy Market Operator. That is AEMO is an operator in the game, not an independent watchdog. In fact an operator that may not itself have acted prudently.

On top of this Chris Uhlmann of the ABC has been virulently critical of the rush to renewables, using what turns out to be techno-babble to sound convincing. His views have skewed the ABC network coverage across all platforms.

So what happened? Continue reading Renewables under attack – again

1. Solar delivers cheapest electricity ‘ever, anywhere, by any technology’

Half the price of coal!

    In last week’s energy auction, Chile accepted a bid from Spanish developer Solarpack Corp. Tecnologica for 120 megawatts of solar at the stunning price of $29.10 per megawatt-hour (2.91 cents per kilowatt-hour or kwh). This beats the 2.99 cents/kwh bid Dubai received recently for 800 megawatts. For context, the average residential price for electricity in the United States is 12 cents per kilowatt-hour.

Bloomberg’s New energy outlook, 2016

In Climate clippings 175, Item 4, I made reference to the Bloomberg New energy outlook, 2016 report which identifies eight “massive” shifts coming soon to power markets. In this post I’d like to take a closer look.

The summary sentence tells us that “coal and gas will begin their terminal decline in less than a decade”. Frequently the title of an article and the summary lead-in sentence are not written by the authors. In this case the “terminal decline” of coal and gas is more than a little misleading. Continue reading Bloomberg’s New energy outlook, 2016

SA green energy crisis

South Australia has rightly been acclaimed as a leader in renewable energy. Already 38% of their electricity comes from wind and solar. Yet

    Futures contracts on the ASX Energy market for electricity delivered in 2016-2018 are between $86 and $90 a MWh in South Australia, compared with between just $37 and $41 MWh in Victoria and between $43 and $48 MWh in NSW.

What’s going on? Continue reading SA green energy crisis

1. New beaut solar technology from UNSW

PERC technology developed by UNSW is likely to become standard in more than half of all solar cell production across the globe by 2020, ushering in new dramatic falls in the cost of solar technology. Continue reading Climate clippings 147

Abbott’s war on wind

On the weekend it emerged that Treasurer Joe Hockey and Finance Minister Mathias Cormann had drafted a letter to the Clean Energy Finance Corporation, telling the $10 billion “green bank” to stop investing in wind power.

The Australian Conservation Foundation’s climate change program manager, Victoria McKenzie-McHarg writes:

    It’s hard to imagine a fledgling industry being attacked and undermined by a national government the way the renewables sector is by the Abbott Government.
