The industry told themselves and the community a lie .. that nuclear was cheap (“too cheap to meter”) and that it was perfectly safe. But, there were always and continue to be cheaper sources of energy, and when incidents did inevitably occ

VPPs are actually a treatment for this issue. By recognizing the value of these new customer-owned systems can provide back to the electricity system, we can give people a reason to stay connected and to contribute back to the common resour

Inverter-based energy systems can set grid frequency and voltage (be grid forming, rather than grid following), and even grid following inverters can provide millisecond-level frequency regulation and contingency response services. South Au

I understand you are trying to make a general argument, but those dynamics are definitely not true of Australia. Our state with the highest share of renewable energy, South Australia, has not seen gas use increase as renewables have replace

> “Australia […] depends on coal” About 60% of Australia’s electricity came from coal over the last 12-months, but this proportion is rapidly declining and all the large coal plants are losing money and slated for closure. https:/&

"evry couple of years" .. umm nope. Try every 10-20 years for the inverter and every 20-30 years for the panels. Roof-top solar in Australia is cheap and almost ubiquitous.

Reasons why Australia doesn't and won't have nuclear: 1. Nuclear is a more expensive sources of energy than our alternatives (uranium ore is a small proportion of the cost stack, and Australia would still need to import nuclear fu

Tracking solar systems can deliver 5-hours of generation. Solar and wind is for super cheap bulk energy. Solar is delivering the cheapest energy in history. Then we use a portfolio of other resources for balancing - grid interconnections; s

Electricity transmission and distribution can be about half the delivered cost of electricity. You can add to this energy losses from centrally generated electricity, which are on average around 10%, but can be as high as 25%. There are alr

This is simply not true. And even if it was nuclear is not a viable response with new projects taking decades to develop. Todays nuclear industry is delivering warmed-up 1970s technology that is expensive, slow, and inflexible. Solar/w

What I choose to use energy for is valid and worthwhile. What you choose to use energy for is invalid and wasteful? Maybe we just get on with decarbonizing the energy system, make sure everyone is paying for the energy they use, and then we

Concerns about Germany’s energy system transition and the question of whether power companies are “screwed” are kind of orthogonal. There are different kinds of power companies. Utilities with a regulated asset base that get to socialize al

I suspect most of the intermittency of wind and solar will be addressed through super-capacity (500% of peak demand, not 100%) and geographic diversity. Batteries will be used for very short-term local balancing and power regulation ... the

Electricity is not a finite resource. We have access to functionally unlimited energy from renewable sources which is becoming exponentially cheaper to convert to electricity, but it is a variable resource. What we need is not 100% renewabl

LNG tankers are today’s energy equivalent of station wagon full of tapes. In the future we might do the same by liquefying hydrogen (or ammonia) to distribute energy from renewable-rich countries to renewable-poor ones.

He writes in the context of the UK. In January 2008 the UK Government gave the go-ahead to build a nuclear power station. This is Hinkley Point C. It might be producing power in 2023. It could cost as much as £22 billion. This kind of proje

The price of energy is definitely trending to free in Australia due to renewables —- just not for every hour of the day, yet. It’s not that electricity will be free when we get there, it’s just that consumers will stop paying for volume (ho
