Energy supply and use

Energy sources, electricity, grids, storage, reliability, cost, and environmental effects.

Energy is more than a power plant

Reliable, affordable energy with risks and environmental impacts that can be examined. Define the service required, including how it should perform during disruption.
Connect generation, transmission, distribution, storage, demand, maintenance, fuel or other inputs, and the people using the service. Examine how changes in one part affect the operating requirements of the rest.
Consider network capacity, construction times, available skills, supply chains, financing, operational limits, environmental requirements, and the need to serve demand throughout a transition.

An energy system must deliver usable energy when and where it is needed.
Compare the full cost of supply, networks, storage, backup, fuel, and environmental effects.

Hydrogen atoms are abundant. Hydrogen fuel is H2 molecules. Water contains hydrogen bound to oxygen; making H2 from it requires energy.

Gas stoves, furnaces, and water heaters: indoor air, ventilation, safety, costs, consumer choice, and rules for new or existing appliances.

Why is generation capacity alone an incomplete measure of an energy system?

Networks do not affect the usefulness of generation.

Nameplate capacity guarantees identical output at every hour.

Energy must reach users when needed, with networks and reliability arrangements.
