Many energy companies (e.g. Exxon Mobil) have already invested in green technology, so industry push-back on climate regulation is not universal. Also representatives are democratically elected, so industry doesn't have total control over the political process. That said it's true that corporations have political clout through lobbying and media campaigns. Some of this is necessary to negotiate regulations with governments. In my opinion a more efficient system / more pure democracy would come by having democratically elected leaders evaluate the positive and negative externalities of various activities independently of industry, and then taxing to internalize these costs.
