Another World Is Here: Turning Emissions Into Fuel With Algae

What we have now: power generation largely using coal and transportation almost exclusively using petroleum, both putting out gigatons of CO2 into the atmosphere. Where we want to be: power generation and transportation almost exclusively using renewable energy methods, putting out very little CO2 into the atmosphere. The problem: we need to reduce CO2 faster than we can realistically shift from fossil fuels to renewable power. The (possible) solution: algae.
