"WE" is an interesting word, isn't it ? The author obviously meant "humanity". Not "him and a bunch of friends".

That being said, this is hacker news, this is for the elite, and startups can disrupt everything, etc...

What can "you and a bunch of friends" do to fix the issue" ?

Because, the people "preventing" us from fixing the issue here are, basically, the whole oil and gas industry, plus the electorate. Which, interestingly, is partly... "WE".
