Some say replacing coal with natural gas – and perhaps nuclear power – can get us to an all-renewable energy future. But is there time?
Generating electricity isn’t limited to burning things or harnessing the power of the wind, waves and sun. What’s the potential for human power?
As the world gets hotter everywhere, some areas get wetter, more drier, and extreme weather becomes more common, how will the potential of hydropower to generate renewable electricity change?
It’s a very enticing idea, making electricity from the predictable motions of the sea. But will we ever really utilize it? And will it generate much power?
Geothermal power is an old renewable energy source, with a huge potential — especially if enhanced geothermal systems can be commercialized.
Giant solar power projects may be flashy, but tapping into the massive potential of rooftop (and backyard, and parking lot) solar power is where we ought to be heading first.
The all-renewables future will require energy storage. Here we explore both current possibilities and technologies that might one day be practical.
