    No. Less restrictions. Currently every area of a city is "zoned" for what is allowed to get built there. "Single family home" (SFH) zoning is the most common, and the strictest: it…

    Carbon credits vs. carbon tax isn't an either/or. Carbon tax discourages emitting carbon into into the atmosphere. Carbon credit encourages sucking carbon out of the atmosphere. Bo…

    Abolish single family zoning. It's terrible for the planet, terrible for economic and racial equity, and terrible for our mental health.

    You're being super disingenuous here. The main priority of Germany's energy transition program was not to lower electricity carbon emissions; it was to phase out nuclear. They were…

    I think you misunderstand the linked doc. Oak Ridge Electric Company, which is a tiny municipal utility that sources electricity from TVA, has 7.09% participation in its green pric…

    Coal is dying in the US. There hasn't been a new power plant built in years , and facilities are getting retired early because it's cheaper to build new solar/wind than to run on c…

    The reason why stuff like this (electrolysis, desalination, etc.) is not widely done is that the capital cost of the facilities is too high. If you spend a bunch of money on an ele…

    The battery in a Nissan LEAF is warranteed to retain 75% of its capacity for 8 years, 160,000 km. So there's a good chance you'd be on a 2nd battery, considering a 3rd at your stag…

    I don't see this as much of a problem. Drag coefficient on a Dodge Ram is 0.357; on a Prius it's 0.29. That's less than a 25% penalty on efficiency.

    The net effect is not even close to the same; it's far worse. Methane is ~36x more potent as a greenhouse gas over a 100-year timespan. This includes the eventual decay to CO2.

    Yes, paper degrades in a landfill. Any carbon-based stuff you put in a landfill generally degrades to methane, which is 25-86 times worse than CO2 when it comes to global warming. …

    Companies piling downtown helps the environment. It allows more people to live close by or commute via mass transportation. Suburban sprawl is the energy-intensive way of living. I…

    2x cost for electric is not typical. The average cost premium is more like 10-15k (and the US government will allow you a $7,500 tax credit for the electric). Of course the top-sel…

    It's carbon neutral when plants decay to carbon dioxide. But they need oxygen for this to happen - and when they don't (like when they're underwater), they decay to methane. And me…

    A company that converts clear-cut land to forest could earn money. There is an entire sector of the economy dedicated to voluntary carbon offsets, and re-forestation efforts are th…

    Climate science is absolutely "a fight between science and self-interested industry". The general scientific principle, that higher levels of CO2 in the air increases Earth's tempe…

    The suburbs are a happy medium. I have a nice yard, a quiet neighborhood, and can drive to any amenity I'd ever want in under 30 minutes. In the USA, quality of schools are another…

    > Lundgren claims that the assistant U.S. attorney on the case told him, “Microsoft wants your head on a platter and I’m going to give it to them.” Are you kidding me.

    When this loophole exists, it's tough to blame Google for not taking advantage of it. You may as well ask them to donate their profits to the federal government.

    China is moving unbelievably fast on electric vehicles. Their government is extremely motivated to stamp out air pollution, and there's nothing really stopping them. It's easy to s…

    CO2, and its interchangeably-used measure of CO2e (which is a sum of all greenhouse gases weighted based on how much they contribute to global warming) is the only pollutant that m…

    Electricians, plumbers, etc. all make very good money without 4- year degrees. But nobody aspires to these professions nowadays - everybody assumed they must go to university.

    The public universities don't cut capacity or quality - they raise costs. And the private colleges follow suit because they can.
