Consistent renewable energy sources such as bioenergy and geothermal are inherently dispatchable, while VRE inputs such as wind or solar energy can be converted to dispatchable generation when combined with some form of energy storage. Geothermal power is constant (base-load), has high operability, is sustainable due to re-injection of cool fluids and is environmentally sound. Unlike power sources such as wind and solar, geothermal energy is dispatchable, meaning that it is both available whenever needed, and can quickly adjust output to match demand. •Dispatchable, 24-hour, base-load electricity In that case, the system could intra-day load for up to 3 times its nominal capacity (e.g., providing 24 MW for 8 hours). "It can provide fully dispatchable power or heat and is scalable in the same way other renewables are." In a recent report, the International Renewable Energy Agency (IRENA) predicted the output of geothermal in Europe could increase eight-fold by 2050. "Geothermal electricity is always on ," said Tester. It all started in Larderello, Italy, more than 100 years ago, when steam from a geothermal well was used to light four bulbs.
