 What's the advantage of enhanced geothermal over, say, wind or solar power? Well, wind and solar power, as is inherent in the name, are variable weather-dependent resources. And so as the sun comes and goes or the wind comes and goes, the output that we get from those clean, renewable resources varies over time. And that means we need to pair those resources with what I call firm resources, technologies that are there whenever you need them for as long as you need them.
