To put this in perspective here is some napkin calculations on how much power dogecoin currently uses:

Assuming an average kh/watt of 2.333 [1] and the total network hashrate of 68 GH/s [2] we can see the network uses about 30 Megawatts of electricity. As a comparison Microsoft uses 250 Megawatts to power for their datacenters [3]. So it is wasteful, yes, but who's to say it's any worse than running datacenters so I can play battlefield 4 with my friends on xbox live which also provides no benefit for charity.

[1]: most ATI cards use this much per kh (https://litecoin.info/Mining_hardware_comparison), this ignores the newer ASIC hardware that is orders of magnitude more efficient
