Solar and wind are unreliable and require unscalable battery storage. Pumped hydro lol. We have a dam in. BC that’s been under construction since 1954. You can’t drop them anywhere you want.
Geothermal and nuclear can go anywhere in comparison to wind, solar and dams.
Let go of wind and solar, focus on clean reliable base load power and we have a chance.

My home battery will be part of a plan next year where the utility can pull electricity from it (paying me a premium rate per kWh and an annual amount for participating).
House generator sales have plummeted, the only people installing them in CA with any frequency are those prone to long outages from winter storms. You’d never install a generator over a battery if your concern is the short excess demand power outages (and you cared about money). I know a bunch of people who installed generators in 2018-2019 and now firmly regret it and wish they had went with a solar + battery. A generator is a money pit, $10-20k to install and hundreds of dollars a day to run it vs a battery that will pay for itself over its useful life.
The cheapest way to create electricity today is solar and it isn’t even close. Saying solar shouldn’t be a major component of the future grid is dumb and a position that is only taken by fossil fuel interests and the morons who parrot their misinformation.
Great way to go,I’m happy I did 10yrs ago. Unfortunately the up front costs are a deterrent for a lot of people. Although the subsidies help a great deal. In order to see a payback you have to commit to staying in your home for quite a few years.Quote:

This is also nonsense isn't it? I live here and my power has never been off. Though it is true at some point in the last decade there were some rolling blackouts. I was scheduled once, but it didn't happen. Recently, the only rolling blackouts I've heard of were in Texas.Quote:

Bozeman’s ‘green tariff’ won’t help the climate crisis

The City of Bozeman reached an agreement with Northwestern Energy that will allow people to voluntarily pay more for “green” solar and wind energy. Missoula is considering signing a similar agreement. But the question that’s going unanswered is: Why NorthWestern’s customers should pay more for solar and wind generated electricity when they are far cheaper to generate than its antiquated coal-fired plants at Colstrip?
The major increases in the amount of NorthWestern’s solar and wind generated electricity have not come from the corporation’s investments in building solar and wind facilities, but rather from facilities built by others that qualify for contracts and avoided cost rates under the Public Utility Regulatory Policies Act of 1978 or PURPA, which was implemented to mandate that, among other things, energy corporations buy electricity from renewable and sustainable sources at rates that match the “avoided costs” of the utilities building new non-renewable generation facilities.
As the technology for wind and solar energy has improved and prices have dropped for solar panels, the cost for renewable sources of electricity that have come online in the last decade are far cheaper, cleaner and more efficient than NWE’s carbon-based electricity generation such as Colstrip or its methane plants.
The Northern Cheyenne are working on a solar project with the Department of Energy. Bozeman’s residents who support green energy would be much better off if NorthWestern simply bought more electricity from projects such as the Northern Cheyenne solar array or the Gallatin Power’s solar battery project near Trident. NWE has an agreement with Gallatin that it could advance. NorthWestern could accept those projects under the standard terms of avoided cost, with 25 year contracts. All NorthWestern ratepayers would all be better off if Bozeman and Missoula supported the Northern Cheyenne solar project, the Gallatin solar project, and convinced NorthWestern to stop fighting PURPA projects.
Bozeman and Missoula could also encourage solar farms of 3 megawatts or less to be built nearby. Small solar farms could get a contract at a price set by the Public Service Commission, which to date has been below the current cost Northwestern pays to generate electricity at Colstrip 3 and 4. If Bozeman was successful, there would be more renewable energy in NorthWestern’s portfolio and ratepayers would pay less not more for green electricity.
Finally there’s the fact that Montana’s Public Service Commission recently granted NorthWestern a massive 28% electricity rate increase, mainly because of the high cost of maintaining its antiquated, massively polluting and very expensive coal-fired generators at Colstrip. Electrical rates will go up even more once Northwestern’s new methane-fired electrical generating facility in Laurel comes online.:fuckyou:
The bottom line is the City of Bozeman will make climate change worse by making residents pay more for green electricity when, in fact, it’s an energy source that costs less to produce, is far cleaner, sustainable and will help keep snow on the Bridgers in the winter and water in the Gallatin in the summer.

That makes sense. At least you are honest about your sources. Now try being honest about renewables and climate change.Quote:

Sure pay back can be slow depending on your energy cost, capital cost and consumption but it’s adding value, for a better resale.Quote:

Why not? Each unit in my complex has their own individual system. Borehole, loop, heat exchanger, pump. And granite canprovide a pretty good extraction rate.Quote:

I don't know the specifics of NorthWestern's power plant economics, but so long as they aren't paying a carbon tax, those old dirty coal plants likely provide the most useful power. Which is another way to say that if your sole concern is cheap power, using an already built dirty fossil plant is a good choice.
That author's key misunderstanding is that a power company must always instantaneously meet the demand for power. So, while wind or solar may be cheaper on a per kilowatt basis, this power is only useful to offset the operation of another power source that provides always available power. E.g. the power company must build (or contract for) enough power generation to meet evening demand and early morning demand every day, when the sun isn't shining and the wind may not blow. It does the power company little good to be able to buy cheap solar kilowatts at noon when the customer wants to run their heater at 6 am.
That said, since power grids are complicated, maybe that author has the best tactic - use misunderstanding to drive outrage against fossil plants and in favor of "cheaper" green plants. Which is probably fine given the fossil plants are only cheap because they freeride by dumping their pollution.
Sounds like it was done when the complex was built, which is reasonable. I'm guessing it's a pretty swanky complex, making the cost of drilling, piping etc a relatively percentage of each unit. As an option for affordable housing that's a problem. As a retrofit for existing housing--that's a problem. And it doesn't matter what the payback and increase in property value is if you can't afford the upfront cost. As far as drilling in granite--that's what caused the Truckee HS project to go way over budget. Most people don't live where it's very hard to drill, though, so Truckee's problem doesn't apply to most.Quote:

We would have built houses around transit. But we're stuck with the built environment we have now and that is what makes it so challenging. And what works in Pemberton BC will not necessarily work in NYC. (Which btw is a lot more energy efficient place to live than Pemberton--since small apartments are far more efficient than freestanding houses and a lot of people in NYC rely on mass transit to the extent that they don't own cars.)
That pretty much sums up why the transition ain’t coming.Quote:

I see a lot of these systems installed on large Mansions owned by the very wealthy who can make use of a 1-1 tax credit to offset the cost of building yet another monster home that will be lived in maybe 6 weeks a year.Quote:
In August 2022, the tax credit for geothermal heat pump installations was extended through 2034. Geothermal equipment that uses the stored solar energy from the ground for heating and cooling and that meets ENERGY STAR requirements at the time of installation is eligible for the tax credit.
NWE has a bunch of Hydro-power available to cover peak demands. Approx. 32% of their power comes from Hydro.Quote:

The upside is once the ground loop is installed it’s got a 50yr lifespan. The indoor unit is pretty much plug and play when it wears out in 20yrs .Quote:
