According to research conducted by Rice University’s Baker Institute for Public Policy, EVs are better than a national renewable energy standard at reducing emissions and cutting oil imports. The study shows that replacing fossil fuel powered cars with EVs in the US would have a better result than imposing renewable energy quotas.The study says: “The single most effective way to reduce US oil demand and foreign imports would be an aggressive campaign to launch electric vehicles into the automotive fleet.”
The US Carbon Management Policy study concludes that if 30 percent of all vehicles were electric by 2050, that would cut US oil use by 2.5 million barrels a day and cut emissions by 7 percent. A national mandate for renewable energy would cut emissions by only half that amount (4%) over the same period.
This Research also found that a carbon tax would actually end up being more costly in the long run and would not impact oil imports in any significant way.
Government support for EVs is important and so is renewable energy to power those cars. However, renewable energy is not a panacea in the short term. As we transition to green energy, renewables can operate alongside cleaner fossil fuels like natural gas. We can also achieve reduced energy demand through greater reliance on public transportation and more efficient building practices including retrofits.
