       | My comment isn't directly related to the OP, but figured it'd be
       | an interesting insight to share as it's very recent for me.
       | 
       | Just finished a motorbike trip in Laos. Fun fact, their largest
       | export is electricity.
       | 
       | Would've never guessed that, right?
       | 
       | 90% of the electricity they generate is exported to neighboring
       | countries - mostly Thailand.
       | 
       | 80% is renewable - Go Laos!
       | 
       | But wait, it may be renewable... but turns out the government is
       | corrupt and constantly sells rights to the highest bidder wanting
       | to build a dam for hydroelectric wherever they want, and usually
       | without any sort of environmental survey - oops. It's the driest
       | country I've been to in a while, many villages had their water
       | access completely destroyed due to upstream dams.
       | 
       | Just a cautionary tale as "renewable" doesn't necessarily mean
       | better - green-washing is absolutely still a thing out there and
       | we should be sure to thoroughly vet information before assuming
       | it's more viable solution for us.

         | but it does happen.

       | Long-term trends clearly demonstrate the energy grid's transition

       | 
       | However, renewables like solar and wind come with unique
       | challenges due to their intermittent nature. They are more
       | variable, harder to forecast, have location constraints, and can
       | benefit from battery storage. These factors lead to a more
       | dynamic grid than before.
       | 
       | For instance, several regions in the country provide five-minute
       | updates on their energy generation mix, enabling near real-time
       | observations of renewable energy effects throughout the day
       | 
       | For example, numerous regions across the country provide updates
       | on their energy generation mix at five-minute intervals, allowing
       | for close to real time observations of these effect of renewables
       | throughout the day.
       | 
       | To help those involved in the energy transition, I created an
       | open-source project called Grid Status
       | (https://github.com/kmax12/gridstatus) that provides fuel mix,
       | wholesale pricing, load, load forecasts, and more.
       | 
       | Additionally, I've developed real-time visualizations to make
       | this data more accessible and easier to comprehend:
       | https://www.gridstatus.io
       | 
       | I hope making this data more accessible and understandable will
       | accelerate the transition away from fossil fuels.

             | 
             | - Costs are low and spread over tons of landowners instead
             | of requiring fundraising and negotiations
             | 
             | - You can have literally thousands of workers busy creating
             | solar power at the same time.
             | 
             | - You get geographic spread and will be less affected by
             | clouds over your central solar plant.
             | 
             | - No single point of failure
             | 
             | - Less need for large and expensive long-distance
             | powerlines
             | 
             | Rooftop solar puts the power to solve a problem in the
             | hands of the people experiencing the problem and eliminates

           | And it proves you wrong.
           | 
           | Let me introduce the state of South Australia. It's an
           | advanced OECD economy, situated at the base end of Australia
           | so far from anywhere it has only 1 transmission line
           | connecting to a neighbouring state, and it's renowned for

           | kilometres of it's 100kv power lines.
           | 
           | It's currently running at 80% renewables:

           | No, the power does no go off at night.
           | 
           | The transition was expensive. SA already had the most
           | expensive electricity in Australia, and during the transition
           | prices did go up for years. But at 80% the transition is
           | almost over (although they need to build more storage), and
           | the price of electricity in SA has been dropping. In fact
           | it's dropped below the pre-transition price, so it's often
           | below the rest of Australia's coal fired generation:

           | 
           | With that example to follow, the rest of the Australian
           | states are gritting their teeth and following South
           | Australia's lead. Teeth gritting is required because we are
           | predicting a 50% jump in electricity prices, during the
           | transition. It's already starting to bite:
           | https://www.afr.com/companies/energy/power-bills-to-rise-

           | the light at the end of the tunnel is lower prices than we

       | 
       | Solar is, nominally, about 50% reliable (if this term isn't
       | comfortable, think "available").
       | 
       | No?
       | 
       | It turns off at night.
       | 
       | Roughly 50% of the time...it does not work.
       | 
       | Wind, on the other hand, does not suffer from this issue. It is
       | much more reliable.
       | 
       | With the addition of a nominal amount of storage wind can easily
       | get up to 95% reliability. Solar, with the same amount of
       | storage, runs about 70% reliability.
       | 
       | This is about power delivery. Consistent. Water bottle in the
       | desert, to use when you need water.
       | 
       | Ignoring all other factors (environmental, wildlife, NIMBY,

       | 
       | Yet, again, to pull this back into the realm of what we should
