There are a few (mostly Bitcoin forks), and you can probably make some profit mining them, but they are not big enough to have a significant impact on the global demand for GPUs. At this point, most crypto projects with any real traction (with the obvious exception of Bitcoin) are either ERC-20 tokens running on Ethereum, or other PoS chains that claim to be better than Ethereum (i.e. Cardano).

We pay about $0.10 in British Columbia, Canada. There is a $0.20 daily base rate and over a certain amount it steps up to $0.14. It’s 95% hydro electric so it’s green too. https://app.bchydro.com/accounts-billing/rates-energy-use/el...
hydro is really not that green: salmons are losing their spawning runs for an example in your area. Also not renewable, because dams get filled with sediment and lose capacity over time.

Yes, that’s why a carbon tax is stupid and „emissions trading“ was invented. Under such a system the government sells a limited amount of certificates during an IPO. Later, the biggest energy consumers buy emission rights from the best energy savers.
Still incentive the energy savers to make investment to save more, so they can sell more rights, and incentive the biggest energy consumer to consume a bit less so they pay less. I wouldn't call that stupid

Where I live (southeastern US) it's $0.089/kWh. There's additional taxes on it that make it functionally closer to $0.10. But yeah, fairly cheap. Which is a good thing because we have electric heat and it's been a very cold month. I'm expecting an about $350 bill.
It is also a bad thing because it makes it reasonable to live in houses that are not properly insulated and just run the air heater on full blast all winter, like I did when I was living in the US. In Denmark the kWh price is around 0.5$ (the wast majority of that is taxes), and the energy efficiency of the house is a key data point in any house purchase and is always listed next to the price.
US building codes are also increasingly strict about insulation and energy efficiency. Premium home builders go even further with insulation. In some locations, new houses are so well insulated and sealed that extra fresh air heat recovery units are necessary to exchange the indoor air.

In many US locations we use gas heat instead of electric. It’s far more efficient to burn fuel for heat instead of burning fuel for electricity and then converting that electricity to heat.

> Is it worth it? > Um. Not really. At current Ethereum prices (2021-02-26), it generates $0.14 of profit per day. It’s still a profit, but very miniscule. The real question is if it makes more money than it costs in electricity. Apple claims it uses 39 W max. That adds up to 0.936 kWh of electricity per day, which we can approximate at 1 kWh. Electricity prices range from ~4¢ to ~20¢ per kWh in the USA, which means…
Re the capital cost: Assuming profit of 10c/day and that an M1 mac is about $1000 it'll be about 274 years before you pay that off.

Is electricity really that cheap in the USA? The cheapest price I've found for my city here in Germany is like 0,24 EUR. And this is already including a new customer discount and cashback. Not even guaranteed green energy... 0,24 EUR is currently ~0,29 USD. That's 0,29 USD for my cheapest price against your most expensive price with 0,20 USD.

> dams get filled with sediment and lose capacity over time I'm struggling to believe this. Can you name one dam on Earth that has lost over 10% capacity due to sediment?
If seems you didn't even did the most basic cursory search on the issue.
Here's literally the first hit on a google search for "dam sediment".

And think about it: what's a dam reservoir other than a big old sedimentation basin.

Also, think about it: hydro power is not the only use for a dam. They are also typically used for things such as flood control, water supply, and energy storage. All of those usecases rely on the sam's ability to hold water (and it's sediments) and lower discharge, if not totally block it.

I recently noticed in the house I just purchased that a lot of cold air was coming in behind my kitchen cabinets and appliances. I pulled out my range and noticed that cold air was rushing through the gap between the drywall and the floor. Fortunately a can of expandable foam was an easy fix.
This house is only 2 years old. Corners were cut when building which makes this home not as efficient as it could be. I'm hoping to make gradual improvements.
Even though my electricity rate is only around $0.12/kwh and my gas bill isn't high, I'd still like to do what I can both for the environment and to save money.
