Nuclear Energy

Vocabulary. Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe, and energy is what holds the nucleus together. There is a huge amount of energy in an atom ''s dense nucleus. In fact, the power that holds the nucleus together is officially called the " strong force ."

How does storage help us balance the grid? | ESO

How does storage help us balance the grid? Energy storage allows us to move energy through time, capturing it when we have too much and saving it for when we don''t have enough. When we have excess electricity, perhaps on a really windy day, we don''t want the extra energy to go to waste. If we can store the electricity to use later, when ...

Pumped Storage Power Station (Francis Turbine)

Introduction. Pumped storage power plants are a type of hydroelectric power plant; they are classified as a form of renewable (green) power generation. Pumped storage plants convert potential energy to electrical energy, or, electrical energy to potential energy. They achieve this by allowing water to flow from a high elevation to a lower ...
