Renewable energy sources represent our best 21st century bet in replacing fossil fuels for generating electricity. Water, wind, waves and tides, solar and geothermal technologies have been in use in different forms for several centuries. Deriving new efficiencies through invention should dramatically alter the way the human species generates and uses energy in the 21st century and beyond.

But the burning of carbon-based fuels has enormous implications for the planet as our population grows, and as energy demands climb. We are in the throes of a paradigm shift around energy, how we create it and deploy it. In this chapter of 21st Century Tech we address our energy future.
