>It's not unreasonable to wait until battery costs come down so mass adoption comes naturally.

But how will battery costs come down if no one invests in it? You sound like the people in my country, forever waiting for the price of wind turbines to drop.

The Danish, German and Dutch government handed out massive subsidies for the first wind parks. Now, because of those subsidies, subsequent wind turbine parks can be built without any subsidies.

But that would've never been possible without those initial investments.

How did light bulbs ever become cheap enough to use without anyone using them? It's called research and development. Throwing out subsidies for specific technologies helps those technologies develop faster, but doesn't necessarily help the best technologies succeed. President Grant might have funded better technologies for getting more whale oil.

Just putting in a cap and trade system makes carbon neutral power generation much more attractive. But it doesn't pick the winners, and maybe some technology you and I are skeptical of turns out to be far better than the others.

They didn't, which is why adoption was gradual.

Had there been a concern for a major global environmental catastrophe which more rapid adoption of electric lighting would help stave off, public subsidies to encourage adoption and accelerate development might have made sense.
