Naomi Klein says, although private businesses invest in renewable energy for their own interests, [ we need four times as much investment as what they are doing ]( http://www.commondreams.org/views/2014/10/03/yep-strawmen-do-keep-coming ) , and there is no reason to expect businesses to go that far without the state's help or pressure. The enormous government [ subsidies for fossil fuels ]( https://stallman.org/archives/2014-may-aug.html#10_July_2014_(US_govt_subsidies_for_fossil_fuels) ) are pertinent here, because they push the market towards fossil fuels, and will continue to do so. Transferring the subsidy to renewables would push the market towards renewables, and a carbon tax would do likewise.
