How West Africa can expand power supply and meet climate goals

Not too long ago, when the idea of solar and wind energy was still hotly debated, critics used to point out the limitations of these energy sources: the sun doesn't always shine and the wind doesn't always blow. But nowadays ...

Finding balance between green energy storage, harvesting

Generating power through wind or solar energy is dependent on the abundance of the right weather conditions, making finding the optimal strategy for storage crucial to the future of sustainable energy usage.

Inertia and the power grid: A guide without the spin

The power grid is evolving to include ever-higher levels of wind and solar generation—which do not provide inertia, historically a key source of grid reliability. Should system planners and operators panic? A new video ...

Hydropower plants to support solar and wind energy in West Africa

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" ...

Uncertain climate future could disrupt energy systems

Extreme weather events—such as severe drought, storms, and heat waves—have been forecast to become more commonplace and are already starting to occur. What has been less studied is the impact on energy systems and how ...

More wind, less hot air

Predictions about how much wind power will be in place by the year 2040 have been too conservative according to research published in the International Journal of Energy Technology and Policy.

Electricity generation

Electricity generation is the process of creating electricity from other forms of energy.

The fundamental principles of electricity generation were discovered during the 1820's and early 1830's by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire, or disc of copper between the poles of a magnet.

For electric utilities, it is the first process in the delivery of electricity to consumers. The other processes, electric power transmission, electricity distribution, and electrical power storage and recovery using pumped storage methods are normally carried out by the electrical power industry.

Electricity is most often generated at a power station by electromechanical generators, primarily driven by heat engines fueled by chemical combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. There are many other technologies that can be and are used to generate electricity such as solar photovoltaics and geothermal power.
