The electric grid has to balance power supply and demand nearly in real-time, requiring power plants to be adjusted on a second-by-second basis. This instantaneous balance is made significantly more complex by renewable energy ...
"The biggest and most complex machine ever built by humankind." That is how University of Wisconsin–Madison doctoral student of electrical engineering Philip Hart describes the nation's power grid.
Seasonal and daily patterns of electricity consumption follow almost identical forms everywhere. Demand is low in the middle of the night when the bulk of humanity is sleeping and it peaks either in the middle of the day ...
A former global champion of renewable energy, Spain wants to make up the ground it lost during the economic crisis when it reversed its policy slashing subsidies and decimating the sector.
On the edge of the Sahara desert, engineers make final checks to a sea of metal mirrors turned towards the sun, preparing for the launch of Morocco's first solar power plant.
Building a $400-million hydroelectric power plant in the world's most arid desert may seem like an engineering debacle, but Chile sees it as a revolutionary way to generate green energy.
Google is nearly doubling the amount of renewable energy feeding its massive data centers that enable more than 1 billion people to search for information, watch video clips and communicate virtually anytime they want.
The Kemper County power plant was supposed to be up and running by now, showing the world how to burn coal without spewing climate-warming carbon pollution into the air.
Over the last few years, Mark Jacobson, a Stanford professor of civil and environmental engineering, and his colleague, Mark Delucchi of the University of California, Berkeley, have produced a series of plans, based on huge ...
Heavily reliant on coal-fired electricity, South Africa is launching ambitious new projects aimed at diversifying its energy sources and avoiding the regular power cuts that have hobbled the economy in recent years.
