The goal here is to finally have women serving as equal.

Marksmanship is an area where women tend to do well. They have a lower center of gravity, less fast-twitch muscle, and a weaker systolic heartbeat. For the opposite reasons, black men tend to be the worst marksmen. In general, if you are good at sports that require sprinting, fast reactions, and upper body strength, you will be bad at shooting.

Anyone involved in bitcoin mining isn't one bit interested in environmental issues

They don't use hydropower because it is "environmental". They use it because it is cheap.

coal is still the cheapest form of energy.

No it isn't. Areas with plentiful hydropower have electricity prices much lower than coal.

My power comes from coal and natural gas and costs less than 11 cents per kWh.

Are you suggesting that is too expensive to mine with?

Yes. That is about twice the price of wholesale hydropower.

Are you suggesting that no one outside of those areas are mining Bitcoin?

There are a few small miners outside these areas, but the big ASIC miners are located in areas where cheap hydropower is available.

So... how much power generated by fossil fuels was consumed "mining" bitcoins last month?

Very close to zero. Bitcoins are mined where power is cheapest, which means where there is plenty of hydropower, like in Iceland and the US Pacific Northwest. It is not cost effective to mine bitcoins using electricity from FFs.

Comment Re:The reason is more simple (Score 1) 688

I found $159 with no money down, but it's only for 7500 miles. If you only drive 7500 miles, you use far less than 250 gallons per year in gas in a Golf. Maybe less than 200 if you are on the highway. Even in a state with $3 gas, you are talking about $750 per year in fuel costs. Not worth it.

The comparable gasoline lease gives you 10,000 miles, so you are also getting less miles in the lease. I don't know what beelsebob's terms are, but it is very rare that a lease would be a better deal than a purchase.

I don't know what tricks your lease is pulling, but an eGolf is in the mid-30s and a regular Golf is at in the low 20s. That is a lot of gas money. If you live in CA, it would probably be worth it if the government is paying for much of the delta. In other parts of the country, you would need to see how long it would take to burn $3000-5000 worth of gas. For my little 20 miles a day it would never be worth it. For a longer commute, it would pay off sooner but the range would become an issue. That means you need a bigger battery, which increases the cost and then makes the payback longer.

It will happen, but it will take some more time for battery prices to come down. ICE engine costs will also go up as efficiency standards become more stringent. If the government removes the subsidy we are a long way off yet.

Editing videos to remove information that doesn't fit his desired portrayal of events, absolutely distorting the true context of events.

He edited a leaked video, which the US Government had claimed did not exist. The events in the video where not as important as the exposure of the lies.

They would still have their one phone call

The "one phone call" is a myth made up by Hollywood. Last time I was arrested, there were several phones in the holding cell, and I was there for four hours. I could make as many phone calls as I wanted, to anyone, either local or collect.
