This looks similar to how mosaic[1] started in 2010, they since moved away from crowdfunding https://en.m.wikipedia.org/wiki/Mosaic_Inc .

Brutal attitude, also wrong. 2 degrees warming is probably inevitable at this point. Not great. But 3 degrees is much worse than 2, and 4 is much worse than 3, etc. There’s no concept of losing, just how bad it will get for future generatio

Sense is great, but way overkill for demand response. Also, measurement needs to be billing grade accuracy, and I don't think Sense is going for that

The market is a little more dynamic than that, wholesale bidding into the ISOs is still the biggest option but many utilities run load shifting programs of various sizes as well. Still, the conclusion is like you said. There's basicall

Not true, it would work with hourly pricing. Still requires smart meters but those are something like 60-70% of homes in the US now. Even without real time or time of use based pricing, load shifting can still be valued and paid for as a se

I have been in this industry for about the same amount of time, and I absolutely could not have said it better. People entering the space can either try to learn from this article or learn these lessons themselves over 2-3 years, I hope the

That's fair. The question of what to do about it is purely political - let's take our best estimates of what the effects of climate change are going to be, our best estimates of the cost and ways to reduce the bad effects, and c

Are you being facetious and saying you can’t prove climate change in the same way you can’t prove gravity exists? Or are you for real? Scientific proof has a different general meaning than what the general population calls proof, but the cl

I think the time frame is too long to make good money investing, the holding costs would kill you as the returns eventually come. I think about it more like where do you want to put down long term roots, given the disruption that will be ca

Methane is a far more potent greenhouse gas than co2, traps about 30x more heat per molecule. On the flip side, it’s half life in the atmosphere until it gets re-absorbed by the earth is on the order of decades, while co2 is on the order of

It's relatively easy for one person to source clean power themselves, just means that technically your payment goes to a wind farm instead of the grid as a whole, but really doesn't change much for the grid. It's much harder

Compared to the rest of the USA (low bar), California is a saint. They started doing Energy Efficiency in the 70s, currently spend $1Bn / year on EE. Energy consumption as a whole in the state has flatlined since they started doing EE

I am loving this new love affair with cleantech and climate change from HN. So much good stuff in the front page last few weeks.

Good analogy - which one of Barry Bonds' 73 home runs in 2001 were because he was on steroids? Hard to pinpoint any single one, but he wouldn't have hit 73 if not for being steroid-enhanced.

I'm similarly optimistic that outcome is possible, maybe even probable, but I'm not excited for it. When it comes to population and the future, the question is less whether we can survive, the question is what kind of world is con

It's all about changing the goalposts. We have probably lost the war against 1.5 deg C climate change, as even if we were to freeze emissions now, I believe we would hit that (need fact check on that). We are currently losing the war a

I agree, would love to find HN for cleantech. I went through this search recently - companies at the nexus of software and cleantech in the bay area, here was my shortlist so you can see what kinds of things these companies are working on:

This is a topic that you can't meaningfully unpack in a short essay. Whether or not you think this has merit, I'd recommend reading Ishmael by Daniel Quinn, it tackles this subject in a more philosophical way and is very thought p

Continent-scale grids of the scale we need look very unlikely to happen due to regulatory / NIMBY concerns - see the decade long delays for Clean Line Energy to get anything moving. Maybe we'll get a federal administration bold en

I'd be very surprised if hydrogen vehicles work out. Hydrogen is not a source but rather a store of energy like a battery is. There's a few practical and technical issues: 1 it would require building out entirely new infrastructur
