My favorite climate change joke: &quot;They say we won&#x27;t act until it&#x27;s too late... Luckily, it&#x27;s too late!&quot;<p>I have a startup in cleantech software, and often I feel very alone on HN. Every time the energy transition or climate change comes up on HN, it seems like most of the replies are either armchair-quarterbacking (&quot;What they should do is...&quot;), dismissive (&quot;They don&#x27;t take into account...&quot;), or futile (&quot;This isn&#x27;t going to be fixed because...&quot;).<p>What I don&#x27;t see is gravity for the magnitude of what&#x27;s going to happen in the next few decades. Over 80% of the world&#x27;s energy currently comes from fossil fuels[1], and the vast majority of that will switch to clean sources within our careers. It&#x27;s a $10.2 trillion dollar transition that will happen in just a few decades[2].<p>So why the the lack of interest from &quot;high growth&quot; HN crowd? There&#x27;s fuck ton of money to be made in the energy transition, and I&#x27;m betting that much of it is going to be in software. Intermittent solar&#x2F;wind generation + storage requires a ton of software to (1) deploy enough to displace fossil sources and (2) actually work reliably. The energy transition isn&#x27;t a research problem anymore, it&#x27;s a scaling problem, which means software opportunity.<p>Maybe it&#x27;s the assumption that salaries aren&#x27;t competitive? Maybe it&#x27;s because most business models in energy tech aren&#x27;t compatible with VC? Maybe it&#x27;s because you have no idea what specific problems there are that need solving? Maybe the assumption is that energy is super slow and bureaucratic?<p>Anyway, it&#x27;s always sad to see the 2nd largest industry in the world (the 1st largest is killing people over energy) always get so categorically poo-pooed on HN. I&#x27;ll keep posting[3][4] and hoping that attitude will eventually change, because we could very much use your talent in making this transition happen.<p>Because it really is too late.<p>[1]: <a href="https:&#x2F;&#x2F;www.eia.gov&#x2F;todayinenergy&#x2F;detail.php?id=11951" rel="nofollow">https:&#x2F;&#x2F;www.eia.gov&#x2F;todayinenergy&#x2F;detail.php?id=11951</a><p>[2]: <a href="http:&#x2F;&#x2F;sdg.iisd.org&#x2F;news&#x2F;investments-in-renewable-energy-to-top-us7-trillion-by-2040&#x2F;" rel="nofollow">http:&#x2F;&#x2F;sdg.iisd.org&#x2F;news&#x2F;investments-in-renewable-energy-to-...</a><p>[3]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=13250336" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=13250336</a><p>[4]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=15127154" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=15127154</a>

I&#x27;m a bit late to the discussion, but I&#x27;m glad to see so many comments here in response to one of the Utility API founders.<p>Just wanted to note something very important:<p>As a co-founder of a very new cleantech software startup, and as a guy coming into the energy industry initially with only a background in software, you need to understand that the energy industry (especially in the US) is incredibly diverse and is really an ecosystem in itself.<p>The market is not just regulated utilities and their customers. There are unregulated markets, power generators, ISOs, cleantech vendors, project developers, installers, financiers, insurance companies, and plenty more players in the space. Each of these actors serves a different role in the process of getting a solar array or battery up and running on a building or out in the field.<p>And to echo some other comments, the hardware is pretty much all there by now, with prices getting lower by the month, and the only thing that&#x27;s missing is the right software to help scale deployment of capital, energy assets, installation labor, etc.<p>[Impending plug is coming]<p>In fact, this is exactly what my company, Station A (<a href="https:&#x2F;&#x2F;stationa.com" rel="nofollow">https:&#x2F;&#x2F;stationa.com</a>), is doing. We&#x27;ve realized that in the commercial and industrial sectors, renewables are seeing slower penetration because the high soft costs associated with project development for the medium-to-small energy consumers. This stems primarily from a lack of access to critical data, biased sales tactics (solar developers only want to sell you solar, even if it won&#x27;t make a difference), and the inability for project developers to really find the right locations to develop with the right technology in a scalable fashion.<p>This sector is ripe for disruption purely with software, as the hardware has become so much more commoditized.

At our 40 acre walnut orchard in Northern California, we water via two wells (30 foot water depth) powered by two PG&amp;E-powered electric pumps (60hp and 20hp). There is an agricultural discount if we run them nights and weekends, so we typically run them on weekends for 12-24 hours. Summer daytime temps are often 90-95 degrees F. Nighttime watering is also helpful due to less water evaporation.<p>But given the duck curve, I expect PG&amp;E will at some point encourage 10am to 3pm power usage. Then it might be cheaper, electricity-wise, to run the pumps 3 times a week, during the heat of the day, instead of overnight on weekends.<p>Bad: More evaporation, so more water use.<p>Good: Maybe cheaper, and since trees reduce their photosynthesis when it gets too hot (to decrease water loss), daytime watering may increase growth by keeping the air temperature lower.

For those of you skeptical that software can address this problem.<p><pre><code> https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Virtual_power_plant </code></pre> Adding storage to the grid is one solution, but adding software that can better influence the demand various customers put on the grid is also surprisingly effective.

If they are expecting to lower energy costs then why do they want more subsidies? Or on the other end a carbon tax to penalize competitors? I&#x27;m sure there are policy prescriptions other than subsidies that can be beneficial to the industry but the ones that seem to get the most discussion are production tax credits and carbon tax.

Power sector isn&#x27;t ready, nor anyone else. Developing power to heavy usage areas from available generation areas is like building new railroads. Success will arise from new, large, government-granted monopoly operations and be slow and pricey without political support at local levels and paying to or seizing from the many literal NIMBY people affected.<p><a href="https:&#x2F;&#x2F;www.technologyreview.com&#x2F;s&#x2F;609766&#x2F;how-to-get-wyoming-wind-to-california-and-cut-80-of-us-carbon-emissions&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.technologyreview.com&#x2F;s&#x2F;609766&#x2F;how-to-get-wyoming...</a><p>Alternatively, of course, solar roof tiles get mandated for new construction and these problems go away.

&quot;The US electricity system is at an extremely sensitive and uncertain juncture. More and more indicators point toward a future in which wind and solar power play a large role. But that future is not locked in. It still depends in large part on policies and economics that, while moving in the right direction, aren’t there yet. And so the people who manage US electricity markets and infrastructure, who must make decisions with 20-, 30-, even 50-year consequences, are stuck making high-stakes bets in a haze of uncertainty.&quot;

I apologize in advance for what is pretty much a tangent, but I wanted to mention a kind of passive wind generator that has no moving parts: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Vaneless_ion_wind_generator" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Vaneless_ion_wind_generator</a><p>It&#x27;s basically one half of Lord Kelvin&#x27;s Thunderstorm turned sideways and powered by wind instead of gravity.<p>Imagine a conductive screen, like an aluminum screen door and, upwind of it, a spray nozzle that emits mist. There is a conductive ring around the nozzle that is DC-biased so that the mist droplets carry a charge. The wind moves the droplets to the screen, collecting the charge.<p>There are no moving parts so you wouldn&#x27;t injure birds.

I don&#x27;t know that fatalism and hopelessness are motivating for decision makers (who are seeking greater margins regardless of policy and lobbies).<p>Is our transformation to 100% clean energy ASAP a certain eventuality? On a long enough timescale, it would be irrational for utilities to not choose <i>both</i> lower cost <i>and</i> more sustainable environmental impact (&#x27;price-rational&#x27;, &#x27;environment-rational&#x27;).<p>We should expect storage and generation costs to continue to fall as we realize even just the current pipeline of capitalizable [storage] research.<p>Solar energy is free.

I’ve mentioned it before. I think I have a new low cost approach to residential solar if anyone is interested in helping or teaming up.

At first glance I read &quot;solar wind is coming&quot; - which is a more alarming and perhaps even less prepared for condition.
