Why renewable energy is seeing a new dawn

National Geographic

Our world is on the verge of a renewable energy renaissance. Technological achievements in the last couple decades offer us the opportunity to break free from the fossil fuels that societies currently rely on and move on to a cleaner alternative. There's no promise that change will be easy or fast, but if we take the first steps, there's hope for a future where renewable energy provides the ...

Thanks for sharing your comment, Wayne-- I noticed the link was an article you've written. Please feel free to also share the link to that article as it's own submitted link to the community to kickstart conversation around it:

Wayne, the fossil fuel industry has spent decades convincing their customers to avoid safe, clean, zero-emission nuclear power, largely based on fear of an unfamiliar science. 

In promoting zero-emission fossil gas (presumably via CC&S), how do you propose to now convince the public to accept underground CO2 repositories, given that naturally occurring CO2 repositories have burped large CO2 plumes, which have suffocated entire villages?  Surely if you make a plea that we should accept the science that says CO2 can be managed safely, your customers may also accept the (historically proven) science that nuclear can be safe, and also inexhaustible and sufficiently storable that every nation can have energy security through (regional) stock-piling (we'll never be able to sell gas to our European allies for a lower price than that from a Russian or Iranian pipeline, and it will never be practical to stockpile more than a few months supply of gas). 

I think there is some hope for the idea of imported energy with supply-side CC&S (Japan may soon begin importing hydrogen and/or ammonia, from a supplier nation that sequesters the carbon).  But I suspect that most of the world will choose a mix of renewables and nuclear to achieve their CO2 emission reduction progress.

Thanks for your comment.  I don't see where C02 repositories have anything to do with choosing the cheapest/cleanest forms of energy.  That is unless we now are talking about Post Modern energy where profit making and public health is not material but replacement of capitalist (i.e., modern) energy is imperative for some vague but hypnotic Post Modern occupational ideology that justifies redundant energy jobs. If so, markets would have to shift from providing the lowest-priced power to irrationally the highest price.

Where in the world has anyone built a gas plant with CCS that can supply power for 1.9c/kWh. A gas plant with CCS will use 20/30% of its power to extract/ compress and transport CO2 to a repository and its capital costs can be 50-150% higher than a plant without CCS

According to the EIA, Industrial natural gas in California is around $8.50/GJ, assuming average efficiency including hot days and part load running of 50% for a CC gas plant that is 6c/kWh just for fuel before the costs of CCS.

Even if the power plant could buy at Henry Hub prices today $2.96/mBTU and pay nothing for transport the fuel cost is still 2c/kWh. operation depreciation, maintenance and finance costs adds at least another 1.5 c so we are now up to at least 3.5c before CCS

And CCS costs who knows, because there are exactly zero 100% capture CCS plants in the world but best guess is another 1.5-3c so now we are at 5-8c/kWh 2.5-4.5 times your claim, if it ever works. In contrast solar+ storage plants are being contracted now at US$28-35/MWh (2.8-3.5c/kWh) and both battery and solar costs are falling

According to NREL 70%+ of Californian electricity can be supplied behind the meter, even before the likely expansion of offshore wind so your claim about the need for a vast new transmission network is unsubstantiated
