We are betting the bank on hydrogen. But are we ready for it?

Green hydrogen holds many promises: it can serve as a "battery" for energy storage, it can be used in the chemical industry, and its only emission will be water vapor. But, unfortunately, green hydrogen is not yet widely ...

Hydrogen, the net-zero hero?

Green hydrogen could transform our energy system and solve many supply and emissions challenges. Whether this happens will depend on how economically it can be produced and how attractive it will be to consumers.

Wind turbine

A wind turbine is a rotating machine which converts the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator, wind power unit (WPU), or wind energy converter (WEC).

This article discusses electric power generation machinery. The windmill article discusses machines used for grain-grinding, water pumping, etc. The article on wind power describes turbine placement, economics and public concerns. The wind energy section of that article describes the distribution of wind energy over time, and how that affects wind-turbine design.
