The best thing to come from the Senate’s floor debate on the Green New Deal late last month may have been these eminently sane remarks, calling on lawmakers of both parties to “move together” in order “to lower emissions, to address the reality of climate change, recognizing that we’ve got an economy we need to keep strong, that we have vulnerable people we need to protect, that we have an environment that we all care about — Republicans and Democrats . ”

Who said it? A Republican, Senator Lisa Murkowski of Alaska, who leads the Energy and Natural Resources Committee. “My hope is we get beyond the high-fired rhetoric to practical, pragmatic, bipartisan solutions,” she said on the chamber floor.

The path is there, if our leaders will only choose to take it. In 2011, Reinventing Fire, an energy study by Rocky Mountain Institute, where we work, showed how a business-led transition could triple energy efficiency, quintuple renewables and sustain an American economy 2.6 times larger in 2050 than it was in 2010 with no oil, coal or nuclear energy, and one-third less natural gas. The net cost was $5 trillion less than business-as-usual — or even more valuable if a price was put on carbon emissions.

Any serious energy transformation effort — whether the Green New Deal or “pragmatic, bipartisan solutions” called for by Senator Murkowski — will need to harness America’s immensely powerful and creative economic engine, not dismantle it. This means unleashing the market in sectors where we already know how to profitably reduce emissions (electricity, transportation, buildings), creating markets for solutions in areas where there aren’t yet enough answers (heavy industry, agriculture) and fixing market failures (unpriced carbon, for instance, or rewarding utilities for selling more electricity rather than cutting your bill).
