Whether it’s the energy used to light up and warm our homes, or the energy consumed in our gas tanks as we drive down the highway, the vast majority of the world’s energy sources come from fossil fuels. But a new generation of technologies is looking to replace coal and oil with cleaner and more efficient sources, like algae fuel, geothermal power and solar panels. New technology is also making it easier to store energy in next-gen battery technologies, and easier to move around on a better power grid. Here’s a round up of stories we covered this month that demonstrate 6 technologies that could shape the future of energy:

Algae fuel
Thin, flexible batteries
Wireless mesh smart grid
Crowdfunding solar
Next-gen geothermal power
Biomimicry LEDs
