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 conc…

Open charge point protocol (OCPP) is used by all EVs and EV chargers currently for charger management, and they are working on an enhancement that will allow your car to directly e…

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. S…

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 pri…

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 …

Yes it is: https://nsidc.org/cryosphere/arctic-meteorology/climate_chan... "Over the past 30 years, it has warmed more than any other region on earth"

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 th…

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 mean…

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 pu…

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 ea…

That's probably been the main driver over time

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'…

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 …

This is the case for almost every island in the world!

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…

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 …

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…

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 c…

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…

Which part of the country are you in? In the northern parts of the country the supply / demand imbalance between summer solar gen and winter heating requirements are huge, either y…
