The Energy Gang

Alternative sources of power are moving into the spotlight.As the share of dispatchable power in our electricity system declines, with coal-fired plants giving way to variable wind and solar, maintaining reliable supplies to keep the lights on becomes more complex. Investment in wind and solar is still vital for making progress towards net zero emissions, but other sources of low-carbon power are also moving into the spotlight. Those can include nuclear and hydrogen generation, as well as wave and tidal power, but there’s another source of renewable energy that’s been attracting a lot of attention recently: geothermal.   Today geothermal accounts for just 0.5% of renewables-based capacity for electricity generation globally, but some think it could play a much bigger role in the future. In the past few years there has been growing interest in geothermal energy, driven by some exciting innovations. Quaise Energy, for example, is developing a millimeter wave drill that they say could enable them
