Renewables Winning Economic Argument

Without question the thermal coalindustry is setting up to simply disappear. The hard driver will be the rapid build out of natural gas burningplants.  No one can stand up against thattype of competition.
Way more important it that sooneror later we will have super conducting power transmission to send poweranywhere to anywhere at slight cost and we will have effective batteries to storesurplus energy as a huge energy buffer. With that environment, wind is a gift that never stops giving andgeothermal also become highly attractive for base load.
Fuel based systems then becomeunattractive, particularly as presently configured.  They were all established on the basis of  a logistical compromise whose economic rational evaporates.
The changeover is well underwayand will become more apparent as time progresses.

A New ManhattanProject

Something interesting is happening in Australia.
A newstudy by the research firm Bloomberg New Energy Finance has found thatunsubsidized renewable energy is now cheaper than fossil fuels like coal andgas.In fact, it’s a lot cheaper.
Data shows that wind farms in Australia can produce energy at AU$80/MWh. Meanwhile, coal plants are producing energy at AU$143/MWh and gas at AU$116/MWh.
Unlike the United States,where energy companies can pollute and have the costs (from illness toenvironmental degradation) picked up by the taxpayers, Australia has a carbon tax, whichpartially explains why renewables have a price advantage. But the data shows that even without the cost of carbon tax factored in; wind energy is still 14-cents cheaper than coal and 18-cents cheaper than gas.  
And this is in a nation that relies more heavily on coal than any otherindustrialized nation in the world. But that coal reliance will soon change, ascompanies in Australiaare quickly adopting new, cheaper renewable energies. As the study found, banksand lending institutions in Australiaare now less and less likely to finance new coal plants, because they've simplybecome a bad investment.
And, while Australian wind is cheapest now, by 2020 - and maybe sooner- solar power will also be cheaper than coal and gas in Australia. The energy game israpidly changing in that country.
Michael Liebrich, the chief executive of Bloomberg New Energy Finance, noted, “The perception that fossil fuels are cheap and renewables are expensive is now out of date.”
Well, here’s a news flash: That perception has been out of date for awhile now – even right here in the United States.
According to the EnergyInformation Administration, looking ahead to 2016, natural gas is thecheapest energy in the United States at roughly $66/MWh. Coal comes insecond at $94/MWh. But right behind coal is renewable wind at $97/MWh,which in large part accounts for why U.S. wind energy production hastripled since 2000.
And, unlike in Australia,none of those USprices account for the externalities associated with fossil fuels likepollution, cancers, military protection, or global warming. In America,the fossil fuel industry has made sure those externalities are paid for not bythe coal and gas energy producers, but instead by you and me.
The fossil fuel industry doesn't pay a penny of the cost of rapidlyaccelerating climate change. Or the healthcare costs from exhaust- andrefinery-driven diseases and deaths from air, water, and other pollution. Notto mention the community costs of decreasing property values when a coal plantis put in your backyard. Nor do they put a cent toward the cost of our Navykeeping the oil shipping lanes open or our soldiers “protecting” the countriesthat “produce” all that oil.
All of these externalities come with fossil fuel production, but prettymuch don't exist with renewable energy production. And those externality costsare not only not paid for by the fossil fuel industry – they're never evenmentioned in the corporate-run “news” media in America.
Research from the Annalsof the New York Academy of Sciences concludes that the total cost ofthese externalities, if paid by the polluters themselves, would raise US fossilfuel prices by as much as nearly $3/MWh. And that’s an extremely conservativeestimate. Which puts wind power on parity with coal in America.
The trend lines here are pretty clear: Buggy whip, meet automobile!  
Renewables are getting cheaper, and fossil fuels are getting moreexpensive.
Which is why we as a nation need to throw everything we have at makingrenewable energies our primary way of powering America into the 21st century.
Think of it as a new ManhattanProject. We need green energy, local energy, and a 21st century smart gridto handle it all.  
Over time, the marketplace will do this for us. But with just aboutevery developed country in the world ahead of us, and our dependence on oilmaking us more and more tightly bound to Middle Eastern dictators and radicals,to wait and hope big transnational corporations will help birth a new Americais both naïve and stupid. Instead of depending on them, we should be recoveringfrom them the cost of those externalities – a carbon tax – that can be used tobuild a new energy infrastructure in America.
Let’s take a lesson from Australia and the Eurozone, whichhave both set up carbon taxes to make 19th century energy barons pay forat least some of the damage they've done. And then use that revenue for a greenenergy revolution here in America.
Considering the threats of climate change, war, and disease, only anidiot – or a fossil-fuel billionaire like Charles or David Koch – would want usto bring in more oil with a pipeline or take any other steps to continue America'sdependence on dirty and costly last-century fuels.
Renewables now cheaper than coal and gas in Australia

A new analysis from research firm Bloomberg New Energy Finance has concluded that electricity from unsubsidised renewable energy is already cheaper than electricity from new-build coal and gas-fired power stations in Australia.
The modeling from the BNEF team in Sydney found that new wind farms could supplyelectricity at a cost of $80/MWh –compared with $143/MWh for new build coal,and $116/MWh for new build gas-fired generation.
These figures include the cost of carbon emissions, but BNEF said evenwithout a carbon price, wind energy remained 14 per cent cheaper than new coaland 18 per cent cheaper than new gas.
“The perception that fossil fuels are cheap and renewables areexpensive is now out of date”, said Michael Liebreich, chief executive ofBloomberg New Energy Finance.
“The fact that wind power is now cheaper than coal and gas in a country with some of the world’s best fossil fuel resources shows that clean energy is a game changer which promises to turn the economics of power systems on its head,” he said.
But before people, such as the conservative parties, reach for the smelling salts and wonder why renewables need support mechanisms such as the renewable energy target, BNEF said this was because new build renewables had to compete with existing plant, and the large-scale RET was essential to enable the construction of new wind and solar farms.
The study also found that Australia’s largest banks and foundthat lenders are unlikely to finance new coal without a substantial riskpremium due to the reputational damage of emissions-intensive investments – ifthey are to finance coal at all.
It also said new gas-fired generation is expensive as the massiveexpansion of Australia’sliquefied natural gas (LNG) export market forces local prices upwards. Thecarbon price adds further costs to new coal- and gas-fired plant and isforecast to increase substantially over the lifetime of a new facility.
BNEF’s analysts also conclude that by 2020, large-scale solar PV willalso be cheaper than coal and gas, when carbon prices are factored in.
In fact, it could be sooner than that, as we reportedyesterday, companies such as Ratch Australia, which owns coal, gas andwind projects, said the cost of new build solar PV was already  around$120-$150/MWh and falling. So much so that it is considering replacing itsageing coal-fired Collinsvillepower station with solar PV. The solar thermalindustry predicts their technologies to fall to $120/MWh by 2020 atthe latest.
The Bloomberg analysis said the Australian economy is likely to be powered extensively by renewable energy in future and that investment in new fossil-fuel power generation may be limited.
“It is very unlikely that new coal-fired power stations will be builtin Australia. They are just too expensive now, compared to renewables”, said Kobad Bhavnagri, head of clean energy research for Bloomberg New Energy Finance in Australia.
“Even baseload gas may struggle to compete with renewables. Australiais unlikely to require new baseload capacity until after 2020, and by this timewind and large-scale PV should be significantly cheaper than burning expensive,export-priced gas.
“By 2020-30 we will be finding new and innovative ways to deal with theintermittency of wind and solar, so it is quite conceivable that we couldleapfrog straight from coal to renewables to reduce emissions as carbon pricesrise.” he added.
The analysis by BNEF is significant. Australia relies more on coal thannearly any other industrialised country, but it also has some of the world’sbest renewables resources, which it has been slow to exploit. But is this likelyto prompt a review of the Coalition’s energy policies – which are based on thepremise that renewable energy is expensive and unreliable? Don’t bet onit.
