Farming algae

We can currently produce biodiesel, jet fuel, biogasoline and plastic with algae. The first phase of a 300-acre algae farm has just been completed in New Mexico. It is set to produce 1.5 million gallons of biofuel annually.

Volcano fracking

Geothermal power is not new to us, but enhanced geothermal systems are a new combination of fracking—hydraulic fracturing—and geothermal energy. You frack into a not-so-active volcano and inject water, which comes back out in the form of steam.

As the steam rises it turns turbines, creating energy. According to Wired magazine, by 2050, this method will be able to generate 100,000 electric megawatts, which is currently the capacity of the entire European Union wind power network.
