The former Massachusetts Governor, currently seeing resurgence in the Iowa polls, makes much of energy independence.
"Our military and economic strength depend on our becoming energy independent -- moving past symbolic measures to actually produce as much energy as we use," Romney said on his Web site.
To that end, he wants to "dramatically increase" federal funding for a host of alternative energy technologies, although he doesn't support raising taxes on oil companies to do it.
"When you tax something, you get less of it," Romney said in an email to CNNMoney.com. "If we raise taxes on investment in domestic energy, we will have less domestic energy production, and will therefore become even more dependent on foreign supplies."
Romney does support drilling in the Alaska National Wildlife Refuge as a way to wean the country off foreign oil.
Romney is unclear about whether or not he supports federal caps on carbon emissions. Most other candidates -- except for Giuliani -- strongly support such a measure.
While he indicated that reducing our carbon footprint was important, he did not directly address the question of whether or not he supports federal caps on emissions. "While it is likely that human activity is contributing to climate change, I am not sure how much, or what we can do to significantly reduce or reverse this effect," Romney said in the email.
