如果你需要给家里供暖，电脑产生的热量就没有被浪费。如果你住的地方使用电暖，那么电脑产生的热量并不是浪费。用电脑产生这些热量，成本是一样的。
如果你有比电暖更便宜的其他供暖方式，那么浪费的只是二者之间的成本差额。
如果是夏天并且你在使用空调，那就是双倍。
比特币生成最终应该会转移到成本最低的地方。也许会是在使用电暖的寒冷气候地区，在那里它实际上等于免费。

The heat from your computer is not wasted if you need to heat your home. If you're using electric heat where you live, then your computer's heat isn't a waste. It's equal cost if you generate the heat with your computer.
If you have other cheaper heating than electric, then the waste is only the difference in cost.
If it's summer and you're using A/C, then it's twice.
Bitcoin generation should end up where it's cheapest. Maybe that will be in cold climates where there's electric heat, where it would be essentially free.
