Atmasphere - average music power delivered to speakers is very low. It is in order of few watts (few percent of max power) while class A takes up to 8x max power. Class A take the same power all the time. When delivers power to speakers (few watts) it dissipates less in the heatsinks.
Cwlondon - Solar panel for class A won't change anything. It is still "polluting" component since you could return this solar energy to grid and reduce emissions.
Same is true for hydrogen - it is very "dirty" fuel since it wastes a lot (90%)of energy in making it using electricity. The fact that energy might be clean (solar, wind etc) doesn't mean anything since, again, it could be returned to grid instead to reduce emissions. Fortunately it will never see daylight since selling hydrogen would be the same as selling dynamite without permit.
