Solar Power at $70 is still twice the price of brown coal

More fake news: Miners are only switching to solar because they can’t get access to cheap coal fired power.

“Miners switch on to renewables”

A better headline would be: Renewable targets make electricity so expensive miners are forced to switch to renewables.

The money quote:

Emily Alford is a principal consultant at Oakley Greenwood …  [she] told The Weekend Australian that solar generation cost about $200 a megawatt hour five years ago, and had dropped to about $70-$80 now.

Compare that to 53 year old Hazelwood coal power which was selling electricity for $30/MWh in it’s last month of operation. When brown coal stations set the price in Victoria they were winning bids at prices like $13/MWh.The cheapest electricity in the world comes from 30 year old brown coal plants.

The $70-$80 estimate is artificially low. Unreliable power makes the other baseload generators more expensive, adding $30/MWh to gas generators for example. Because the back up generators have to be there, not earning money while solar feeds in, they have to charge more to recoup those costs in a shorter working period. Doh. So add that cost to solar, not the gas.

Compare the real costs and weep:

Gates on renewables: How would Tokyo survive a 3 day typhoon with unreliable energy?

Make no mistake, Bill Gates totally believes the climate change scare story but even he can see that renewables are not the answer, it’s not about the cost, it’s the reliability.

He quotes Vaslav (possibly Vaclav Smil?):

Here’s Toyko, 27 million people, you have three days of a cyclone every year. It’s 23GW of electricity for three days. Tell me what battery solution is going sit there and provide that power.

 As Gates says: Let’s not jerk around. You’re multiple orders of magnitude — … — That’s nothing, that doesn’t solve the reliability problem.

During storms clouds cut solar panel productivity (unless hail destroys it) and wind turbines have to shut down in high winds.

The whole interview was part of a presentation at Stanford late last year:

Cheap renewables won’t stop global warming, says Bill Gates
